Gridcoin 126.96.36.199-Mandatory "Fern" Release
https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/188.8.131.52 Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that. Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap. We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout. Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.
Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now. Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date. The transition height is also when the team requirement will be relaxed for the network.
Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.
The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use. There are so many goodies here it is hard to summarize them all. I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures. The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!
Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.
Network magnitude unit pinned to a static value of 0.25
Max research reward allowed per block raised to 16384 GRC (from 12750 GRC)
New CPIDs begin accruing research rewards from the first superblock that contains the CPID instead of from the time of the beacon advertisement
500 GRC research reward limit for a CPID's first stake
6-month expiration for unclaimed rewards
10-block spacing requirement between research reward claims
Rolling 5-day payment-per-day limit
Legacy tolerances for floating-point error and time drift
The need to include a valid copy of a CPID's magnitude in a claim
10-block emission adjustment interval for the magnitude unit
One-time beacon activation requires that participants temporarily change their usernames to a verification code at one whitelisted BOINC project
Verification codes of pending beacons expire after 3 days
Self-service beacon removal
Burn fee for beacon advertisement increased from 0.00001 GRC to 0.5 GRC
Rain addresses derived from beacon keys instead of a default wallet address
Beacon expiration determined as of the current block instead of the previous block
The ability for developers to remove beacons
The ability to sign research reward claims with non-current but unexpired beacons
As a reminder:
Beacons expire after 6 months pass (180 days)
Beacons can be renewed after 5 months pass (150 days)
Renewed beacons must be signed with the same key as the original beacon
Magnitudes less than 1 include two fractional places
Magnitudes greater than or equal to 1 but less than 10 include one fractional place
A valid superblock must match a scraper convergence
Superblock popularity election mechanics
Yes/no/abstain and single-choice response types (no user-facing support yet)
To create a poll, a maximum of 250 UTXOs for a single address must add up to 100000 GRC. These are selected from the largest downwards.
Burn fee for creating polls scaled by the number of UTXOs claimed
50 GRC for a poll contract
0.001 GRC per claimed UTXO
Burn fee for casting votes scaled by the number of UTXOs claimed
0.01 GRC for a vote contract
0.01 GRC to claim magnitude
0.01 GRC per claimed address
0.001 GRC per claimed UTXO
Maximum length of a poll title: 80 characters
Maximum length of a poll question: 100 characters
Maximum length of a poll discussion website URL: 100 characters
Maximum number of poll choices: 20
Maximum length of a poll choice label: 100 characters
Magnitude, CPID count, and participant count poll weight types

Just like the first Protocol (Core 1.0), the TKEY asset used in the TkeyNet network — there are no changes in this plan. After launching TkeyNet, you can transfer TKEY to any user on the TKEY network without any restrictions.
Transactions in TkeyNet will be much faster than it was before. You can check it in practice.
The Protocol has a built-in TkeyConnect module, which allows you to connect various blockchains to our network to conduct transactions directly in the TkeyNet blockchain. Besides, TkeyConnect meets the international ISO and ISIN standards, which also allows you to conduct transactions with Fiat currencies and shares in the TkeyNet blockchain. TkeyConnect creates a flexible system, giving users the ability to store and conduct transactions in any assets, be it Bitcoin, Ethereum, Litecoin or dollars, euros, etc. https://preview.redd.it/rkroh5ulbjg51.png?width=700&format=png&auto=webp&s=c47a094c9ae3d22131bebea80badafd0dd1f8dd6
If the previous software based on the Core 1.0 Protocol, after switching to TkeyNet, wallets, a blockchain search engine, and other software related to the project will be adapted to the new Protocol.
Contact information and support service
Email addresses of the support service and other departments will be transferred to other service providers and will structure in the following areas: B2B and B2C. The list of email addresses will publish after updates are complete.
B2B (business-to-business)a term that means that a company or a division of a company sells its goods/services to corporate clients, that is, to other companies.B2C (business-to-consumer)is a term that refers to the commercial relationship between an organization (Business) and a private, so-called “end” consumer.
Information about the project, the company, and its products will subdivide into two websites: tkeycoin.com and tkey.org. The purpose of this division is to simplify product navigation, improve the appearance of pages for each product and solution, and update content. The solution is modular. The information will be structured according to sections and sites, dividing the corporate and user segments. As the products develop, the information will be updated. Technical specifications, documentation, and a description of the Protocol and its features will appear on the official website: tkey.org. Sections will fill in gradually.
Testing and launching TkeyNet
Between July 22 and July 24, Telnet was successfully launched in testnet mode. Our team is actively testing the entire TkeyNet network and its functions. The system is tested with different scenarios, its effectiveness is checked when working with high loads, and the security of the entire system is audited. Testing of TkeyNet is an important stage of production aimed at detailed research of the program code and identification of errors in the system operation. Comprehensive testing, which is carried out by our team, is necessary to determine the level of readiness of the system for subsequent operation. Testing is based on a set of test scenarios that cover the main business operations.
The testing process contains all the life cycle activities: dynamic and static indicators. The testing process involves planning, preparing, and evaluating a software product. The purpose of testing is to determine that all meet the requirements described, as well as to show that they are suitable for the stated purposes and for detecting errors.
You can buy or sell TKEY only on the exchange and not in any other source. Private transactions are subject to high risks. Once again, we remind you that at the time of updates, any transactions with TKEY will be invalid.
Safety of funds
If you use a local wallet on your computer, make a backup copy of the wallet.dat file. If you use a TkeySpace mobile wallet, make a backup copy of the private key (backup phrase).
Transactions before updates are completed
During updates-no transactions can be made on the network, which means that any private dealing made at the time of updates will be invalid. Additionally, we ask you to refrain from any actions related to TKEY until the end of updates protocol, including starting mining, local wallets, and reinstalling them.
Testing of the system and its functions takes place in a stable mode without days off. The test results that will receive at the end of this week will reflect the current state of Affairs. We will get up-to-date information about the end date of updates and the planned release date of TkeyNet. An announcement of interim test results, as well as future updates, will be published at the end of this week or early next.
Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything. The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years. In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.
UPDATED - Groestlcoin Core 2.18.2
This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables. NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.
Builds are now done through Gitian
Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the "high water mark") before dropping additional messages. The default value is 1,000, the same as was used for previous releases.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:1441:1441 (this is an extra :1441 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it's ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers.
A new short about the JSON-RPC interface describes cases where the results of anRPC might contain inconsistencies between data sourced from differentsubsystems, such as wallet state and mempool state.
A new document introduces Groestlcoin Core's BIP174 interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor (https://github.com/groestlcoin/groestlcoin/blob/mastedoc/descriptors.md) documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.
A new --disable-bip70 option may be passed to ./configure to prevent Groestlcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Groestlcoin Core to libssl vulnerabilities in the past, builders who don't need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)
getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured bythe -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. Currently, it returns an array of the currently active commands and how long they've been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information aboutit, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyze psbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.
getpeerinfo now returns an additional minfeefilter field set to the peer's BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional "bip125-replaceable" value indicating whether thetransaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of"0" may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable Boolean field when Groestlcoin Core knows enough about the address's scriptPubKey, optional redeemScript, and optional witnessScript for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label "coldwallet" in earlier releases of Groestlcoin Core, subsequently importing the private key would default to resetting the address's label to the default empty-string label (""). In this release, the previous label of "cold wallet" will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows:
If a blockhash is provided, check the corresponding block.
If no blockhash is provided, check the mempool.
If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A desc parameter can be provided instead of the "scriptPubKey" in are quest, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HDseed. They cannot be opened in software older than 2.18.2. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 2.17.2. Encrypting a blank wallet will also set a HD seed for it.
signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 2.17.2.
The 'account' API is removed after being deprecated in v2.17.2 The 'label' API was introduced in v2.17.2 as a replacement for accounts. See the release notes from v2.17.2 for a full description of the changes from the 'account' API to the 'label' API.
addwitnessaddress is removed after being deprecated in version 2.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart groestlcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly,script, hex, pubkeys, sigsrequired, pubkey, embedded,iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddressand getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.
A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).
A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for "pay only the required fee" has been removed. Instead, the user can simply decrease the value in the Custom Fee rate field all the way down to the node's configured minimumrelay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and thedisable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (useCXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" for setting the deployment sdkversion)
A new groestlcoin-wallet tool is now distributed alongside Groestlcoin Core's other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.
Since version 2.16.0, Groestlcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely used software. Starting with Groestlcoin Core 2.20.1 (expected about a year after 2.18.2), Groestlcoin Core will default to native segwitaddresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Groestlcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Groestlcoin Core 2.19.1. P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn't want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Groestlcoin Core release from 2.16.0 up.)
BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v2.17.2 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.
The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block but returned a generic "duplicate" rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns "duplicate" for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if thebip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).
The -usehd configuration option was removed in version 2.16.0 From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.
This release allows peers that your node automatically disconnected for misbehaviour (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don't have many other peers). Previously, Groestlcoin Core banned the IP addresses of misbehaving peers for a period (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.
The key metadata will need to be upgraded the first time that the HDseed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Bitcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Groestlcoin Core. See their project page for details.
This release changes the Random Number Generator (RNG) used from OpenSSL to Groestlcoin Core's own implementation, although entropy gathered by Groestlcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Groestlcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.
On macOS, Groestlcoin Core now opts out of application CPU throttling ("app nap") during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.
How to Upgrade?
Windows If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet
Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network. GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.
Groestlcoin Mainnet & Testnet supported
Multiple wallet support
Electrum - Support for both random and custom peers
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
BIP39 Passphrase functionality
Support for Segwit-compatible & legacy addresses in settings
Support individual private key sweeping
UTXO blacklisting - Accessible via the Transaction Detail view, this allows users to blacklist any utxo that they do not wish to include in their list of available utxo's when sending transactions. Blacklisting a utxo excludes its amount from the wallet's total balance.
Ability to Sign & Verify Messages
Support BitID for password-free authentication
Coin Control - This can be accessed from the Send Transaction view and basically allows users to select from a list of available UTXO's to include in their transaction.
HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled. HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user. Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.
Simplified payment verification for fast mobile performance
Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases. This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats. To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.
If a word is wrong, the tool will try to suggest the closest option.
If a word is missing or unknown, please type "?" instead and the tool will find all relevant options.
NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator. VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline. If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address. VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase. VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).
Fixed size arithmetic
Fast Modular Inversion (Delayed Right Shift 62 bits)
SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
Use some properties of elliptic curve to generate more keys
SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet. If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet
Ability to output keys to a text file (And shows button to open that directory)
Show and hide the private key with a simple toggle switch
Show full output of commands
Ability to choose between Processor (CPU) and Graphics Card (GPU) ( NVidia ONLY! )
Features both a Light and Dark Material Design-Style Themes
Free software - MIT. Anyone can audit the code.
Written in C# - The code is short, and easy to review.
Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode. This wallet was previously deprecated but has been brought back to life with modern standards.
Works via TOR or SOCKS5 proxy
Can use bootstrap.dat format as blockchain database
Import/Export blockchain to/from bootstrap.dat
Import wallet.dat from Groestlcoin-qt wallet
Export wallet to wallet.dat
Use both groestlcoin-wpf and groestlcoin-qt with the same addresses in parallel. When you send money from one program, the transaction will automatically be visible on the other wallet.
Rescan blockchain with a simple mouse click
Works as a full node and listens to port 1331 (listening port can be changed)
Fast Block verifying, parallel processing on multi-core CPUs
Mine Groestlcoins with your CPU by a simple mouse click
All private keys are kept encrypted on your local machine (or on a USB stick)
Lite - Has a lightweight "thin client" mode which does not require a new user to download the entire Groestlcoin chain and store it
Free and decentralised - Open Source under GNU license
Fixed Import/Export to wallet.dat
Rescan wallet option
Change wallet password option
Address type and Change type options through *.conf file
Import from bootstrap.dat - It is a flat, binary file containing Groestlcoin blockchain data, from the genesis block through a recent height. All versions automatically validate and import the file "grs.bootstrap.dat" in the GRS directory. Grs.bootstrap.dat is compatible with Qt wallet. GroestlCoin-Qt can load from it.
In Full mode file %APPDATA%\Groestlcoin-WPF\GRS\GRS.bootstrap.dat is full blockchain in standard bootstrap.dat format and can be used with other clients.
Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node. It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node. Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine. Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in. Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet. Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.
Use your own node
Uses less CPU and RAM than ElectrumX
Used intermittently rather than needing to be always-on
Doesn't require an index of every Groestlcoin address ever used like on ElectrumX
UPDATED – Android Wallet 7.38.1 - Main Net + Test Net
The app allows you to send and receive Groestlcoin on your device using QR codes and URI links. When using this app, please back up your wallet and email them to yourself! This will save your wallet in a password protected file. Then your coins can be retrieved even if you lose your phone.
Add confidence messages, helping users to understand the confidence state of their payments.
Handle edge case when restoring via an external app.
Count devices with a memory class of 128 MB as low ram.
Introduce dark mode on Android 10 devices.
Reduce memory usage of PIN-protected wallets.
Tapping on the app's version will reveal a checksum of the APK that was installed.
Fix issue with confirmation of transactions that empty your wallet.
Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet. Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.
An extensive guide for cashing out bitcoin and cryptocurrencies into private banks
Hey guys. Merry Xmas ! I am coming back to you with a follow up post, as I have helped many people cash out this year and I have streamlined the process. After my original post, I received many requests to be more specific and provide more details. I thought that after the amazing rally we have been attending over the last few months, and the volatility of the last few days, it would be interesting to revisit more extensively. The attitude of banks around crypto is changing slowly, but it is still a tough stance. For the first partial cash out I operated around a year ago for a client, it took me months to find a bank. They wouldn’t want to even consider the case and we had to knock at each and every door. Despite all my contacts it was very difficult back in the days. This has changed now, and banks have started to open their doors, but there is a process, a set of best practices and codes one has to follow. I often get requests from crypto guys who are very privacy-oriented, and it takes me months to have them understand that I am bound by Swiss law on banking secrecy, and I am their ally in this onboarding process. It’s funny how I have to convince people that banks are legit, while on the other side, banks ask me to show that crypto millionaires are legit. I have a solid background in both banking and in crypto so I manage to make the bridge, but yeah sometimes it is tough to reconcile the two worlds. I am a crypto enthusiast myself and I can say that after years of work in the banking industry I have grown disillusioned towards banks as well, like many of you. Still an account in a Private bank is convenient and powerful. So let’s get started.
A. What is required to open an account in a Private bank when you made your fortune through crypto.
There are two different aspects to your onboarding in a Swiss Private bank, compliance-wise. *The origin of your crypto wealth *Your background (residence, citizenship and probity) These two aspects must be documented in-depth. How to document your crypto wealth. Each new crypto millionaire has a different story. I may detail a few fun stories later in this post, but at the end of the day, most of crypto rich I have met can be categorized within the following profiles: the miner, the early adopter, the trader, the corporate entity, the black market, the libertarian/OTC buyer. The real question is how you prove your wealth is legit. 1. Context around the original amount/investment Generally speaking, your first crypto purchase may not be documented. But the context around this acquisition can be. I have had many cases where the original amount was bought through Mtgox, and no proof of purchase could be provided, nor could be documented any Mtgox claim. That’s perfectly fine. At some point Mtgox amounted 70% of the bitcoin transactions globally, and people who bought there and managed to withdraw and keep hold of their bitcoins do not have any Mtgox claim. This is absolutely fine. However, if you can show me the record of a wire from your bank to Tisbane (Mtgox's parent company) it's a great way to start. Otherwise, what I am trying to document here is the following: I need context. If you made your first purchase by saving from summer jobs, show me a payroll. Even if it was USD 2k. If you acquired your first bitcoins from mining, show me the bills of your mining equipment from 2012 or if it was through a pool mine, give me your slushpool account ref for instance. If you were given bitcoin against a service you charged, show me an invoice. 2. Tracking your wealth until today and making sense of it. What I have been doing over the last few months was basically educating compliance officers. Thanks God, the blockchain is a global digital ledger! I have been telling my auditors and compliance officers they have the best tool at their disposal to lead a proper investigation. Whether you like it or not, your wealth can be tracked, from address to address. You may have thought all along this was a bad feature, but I am telling you, if you want to cash out, in the context of Private Banking onboarding, tracking your wealth through the block explorer is a boon. We can see the inflows, outflows. We can see the age behind an address. An early adopter who bought 1000 BTC in 2010, and let his bitcoin behind one address and held thus far is legit, whether or not he has a proof of purchase to show. That’s just common sense. My job is to explain that to the banks in a language they understand. Let’s have a look at a few examples and how to document the few profiles I mentioned earlier. The trader. I love traders. These are easy cases. I have a ton of respect for them. Being a trader myself in investment banks for a decade earlier in my career has taught me that controlling one’s emotions and having the discipline to impose oneself some proper risk management system is really really hard. Further, being able to avoid the exchange bankruptcy and hacks throughout crypto history is outstanding. It shows real survival instinct, or just plain blissed ignorance. In any cases traders at exchange are easy cases to corroborate since their whole track record is potentially available. Some traders I have met have automated their trading and have shown me more than 500k trades done over the span of 4 years. Obviously in this kind of scenario I don’t show everything to the bank to avoid information overload, and prefer to do some snacking here and there. My strategy is to show the early trades, the most profitable ones, explain the trading strategy and (partially expose) the situation as of now with id pages of the exchanges and current balance. Many traders have become insensitive to the risk of parking their crypto at exchange as they want to be able to trade or to grasp an occasion any minute, so they generally do not secure a substantial portion on the blockchain which tends to make me very nervous. The early adopter. Provided that he has not mixed his coin, the early adopter or “hodler” is not a difficult case either. Who cares how you bought your first 10k btc if you bought them below 3$ ? Even if you do not have a purchase proof, I would generally manage to find ways. We just have to corroborate the original 30’000 USD investment in this case. I mainly focus on three things here: *proof of early adoption I have managed to educate some banks on a few evidences specifically related to crypto markets. For instance with me, an old bitcointalk account can serve as a proof of early adoption. Even an old reddit post from a few years ago where you say how much you despise this Ripple premined scam can prove to be a treasure readily available to show you were early. *story telling Compliance officers like to know when, why and how. They are human being looking for simple answers to simple questions and they don’t want like to be played fool. Telling the truth, even without a proof can do wonders, and even though bluffing might still work because banks don’t fully understand bitcoin yet, it is a risky strategy that is less and less likely to pay off as they are getting more sophisticated by the day. *micro transaction from an old address you control This is the killer feature. Send a $20 worth transaction from an old address to my company wallet and to one of my partner bank’s wallet and you are all set ! This is gold and considered a very solid piece of evidence. You can also do a microtransaction to your own wallet, but banks generally prefer transfer to their own wallet. Patience with them please. they are still learning. *signature message Why do a micro transaction when you can sign a message and avoid potentially tainting your coins ? *ICO millionaire Some clients made their wealth participating in ETH crowdsale or IOTA ICO. They were very easy to deal with obviously and the account opening was very smooth since we could evidence the GENESIS TxHash flow. The miner Not so easy to proof the wealth is legit in that case. Most early miners never took screenshot of the blocks on bitcoin core, nor did they note down the block number of each block they mined. Until the the Slashdot article from August 2010 anyone could mine on his laptop, let his computer run overnight and wake up to a freshly minted block containing 50 bitcoins back in the days. Not many people were structured enough to store and secure these coins, avoid malwares while syncing the blockchain continuously, let alone document the mined blocks in the process. What was 50 BTC worth really for the early miners ? dust of dollars, games and magic cards… Even miners post 2010 are generally difficult to deal with in terms of compliance onboarding. Many pool mining are long dead. Deepbit is down for instance and the founders are MIA. So my strategy to proof mining activity is as follow: *Focusing on IT background whenever possible. An IT background does help a lot to bring some substance to the fact you had the technical ability to operate a mining rig. *Showing mining equipment receipts. If you mined on your own you must have bought the hardware to do so. For instance mining equipment receipts from butterfly lab from 2012-2013 could help document your case. Similarly, high electricity bill from your household on a consistent basis back in the day could help. I have already unlocked a tricky case in the past with such documents when the bank was doubtful. *Wallet.dat files with block mining transactions from 2011 thereafter This obviously is a fantastic piece of evidence for both you and me if you have an old wallet and if you control an address that received original mined blocks, (even if the wallet is now empty). I will make sure compliance officers understand what it means, and as for the early adopter, you can prove your control over these wallet through a microtransaction. With these kind of addresses, I can show on the block explorer the mined block rewards hitting at regular time interval, and I can even spot when difficulty level increased or when halvening process happened. *Poolmining account. Here again I have educated my partner bank to understand that a slush account opened in 2013 or an OnionTip presence was enough to corroborate mining activity. The block explorer then helps me to do the bridge with your current wallet. *Describing your set up and putting it in context In the history of mining we had CPU, GPU, FPG and ASICs mining. I will describe your technical set up and explain why and how your set up was competitive at that time. The corporate entity Remember 2012 when we were all convinced bitcoin would take over the world, and soon everyone would pay his coffee in bitcoin? How naïve we were to think transaction fees would remain low forever. I don’t blame bitcoin cash supporters; I once shared this dream as well. Remember when we thought global adoption was right around the corner and some brick and mortar would soon accept bitcoin transaction as a common mean of payment? Well, some shop actually did accept payment and held. I had a few cases as such of shops holders, who made it to the multi million mark holding and had invoices or receipts to proof the transactions. If you are organized enough to keep a record for these trades and are willing to cooperate for the documentation, you are making your life easy. The digital advertising business is also a big market for the bitcoin industry, and affiliates partner compensated in btc are common. It is good to show an invoice, it is better to show a contract. If you do not have a contract (which is common since all advertising deals are about ticking a check box on the website to accept terms and conditions), there are ways around that. If you are in that case, pm me. The black market Sorry guys, I can’t do much for you officially. Not that I am judging you. I am a libertarian myself. It’s just already very difficult to onboard legit btc adopters, so the black market is a market I cannot afford to consider. My company is regulated so KYC and compliance are key for me if I want to stay in business. Behind each case I push forward I am risking the credibility and reputation I have built over the years. So I am sorry guys I am not risking it to make an extra buck. Your best hope is that crypto will eventually take over the world and you won’t need to cash out anyway. Or go find a Lithuanian bank that is light on compliance and cooperative. The OTC buyer and the libertarian. Generally a very difficult case. If you bought your stack during your journey in Japan 5 years ago to a guy you never met again; or if you accumulated on https://localbitcoins.com/ and kept no record or lost your account, it is going to be difficult. Not impossible but difficult. We will try to build a case with everything else we have, and I may be able to onboard you. However I am risking a lot here so I need to be 100% confident you are legit, before I defend you. Come & see me in Geneva, and we will talk. I will run forensic services like elliptic, chainalysis, or scorechain on an extract of your wallet. If this scan does not raise too many red flags, then maybe we can work together ! If you mixed your coins all along your crypto history, and shredded your seeds because you were paranoid, or if you made your wealth mining professionally monero over the last 3 years but never opened an account at an exchange. ¯_(ツ)_/¯ I am not a magician and don’t get me wrong, I love monero, it’s not the point. Cashing out ICOs Private companies or foundations who have ran an ICO generally have a very hard time opening a bank account. The few banks that accept such projects would generally look at 4 criteria: *Seriousness of the project Extensive study of the whitepaper to limit the reputation risk *AML of the onboarding process ICOs 1.0 have no chance basically if a background check of the investors has not been conducted *Structure of the moral entity List of signatories, certificate of incumbency, work contract, premises... *Fiscal conformity Did the company informed the authorities and seek a fiscal ruling.
B. The tax issue I am not a tax specialist, but I can say that this year I have seen it all. Again I am not judging. You made $100m hodling, and still wouldn’t pay your taxes ? Your decision.I personally advise everyone to pay their taxes, but also to be generous, to give to charities. I mean you eventually made it. Good for you. What about you contribute to make the world a better place now? I will stop patronizing you. It’s just my 2cts, and it’s your money.
For the record, I am not into the tax avoidance business, so people come to me with a set up and I see if I can make it work within the legal framework imposed to me. First, stop thinking Switzerland is a “offshore heaven” Swiss banks have made deals with many governments for the exchange of fiscal information. If you are a French citizen, resident in France and want to open an account in a Private Bank in Switzerland to cash out your bitcoins, you will get slaughtered (>60%). There are ways around that, and I could refer you to good tax specialists for fiscal optimization, but I cannot organize it myself. It would be illegal for me. Swiss private banks makes it easy for you to keep a good your relation with your retail bank and continue paying your bills without headaches. They are integrated to SEPA, provide ebanking and credit cards. For information, these are the kind of set up some of my clients came up with. It’s all legal; obviously I do not onboard clients that are not tax compliant. Further disclaimer: I did not contribute myself to these set up. Do not ask me to organize it for you. I won’t. EU tricks Swiss lump sum taxation Foreign nationals resident in Switzerland can be taxed on a lump-sum basis if they are not gainfully employed in our country. Under the lump-sum tax regime, foreign nationals taking residence in Switzerland may choose to pay an expense-based tax instead of ordinary income and wealth tax. Attractive cantons for the lump sum taxation are Zug, Vaud, Valais, Grisons, Lucerne and Berne. To make it short, you will be paying somewhere between 200 and 400k a year and all expenses will be deductible. Switzerland has adopted a very friendly attitude towards crypto currency in general. There is a whole crypto valley in Zug now. 30% of ICOs are operated in Switzerland. The reason is that Switzerland has thrived for centuries on banking secrecy, and today with FATCA and exchange of fiscal info with EU, banking secrecy is dead. Regulators in Switzerland have understood that digital ledger technologies were a way to roll over this competitive advantage for the generations to come. Switzerland does not tax capital gains on crypto profits. The Finma has a very pragmatic approach. They have issued guidance- updated guidelines here. They let the business get organized and operate their analysis on a case per case basis. Only after getting a deep understanding of the market will they issue a global fintech license in 2019. This approach is much more realistic than legislations which try to regulate everything beforehand. Italy new tax exemption. It’s a brand new fiscal exemption. Go to Aoste, get residency and you could be taxed a 100k/year for 10years. Yes, really. Portugal What’s crazy in Europe is the lack of fiscal harmonization. Even if no one in Brussels dares admit it, every other country is doing fiscal dumping. Portugal is such a country and has proved very friendly fiscally speaking. I personally have a hard time trusting Europe. I have witnessed what happened in Greece over the last few years. Some of our ultra high net worth clients got stuck with capital controls. I mean no way you got out of crypto to have your funds confiscated at the next financial crisis! Anyway. FYI Malta Generally speaking, if you get a residence somewhere you have to live there for a certain period of time. Being stuck in Italy is no big deal with Schengen Agreement, but in Malta it is a different story. In Malta, the ordinary residence scheme is more attractive than the HNWI residence scheme. Being an individual, you can hold a residence permit under this scheme and pay zero income tax in Malta in a completely legal way. Monaco Not suitable for French citizens, but for other Ultra High Net worth individual, Monaco is worth considering. You need an account at a local bank as a proof of fortune, and this account generally has to be seeded with at least EUR500k. You also need a proof of residence. I do mean UHNI because if you don’t cash out minimum 30m it’s not interesting. Everything is expensive in Monaco. Real Estate is EUR 50k per square meter. A breakfast at Monte Carlo Bay hotel is 70 EUR. Monaco is sunny but sometimes it feels like a golden jail. Do you really want that for your kids? Dubaï
Set up a company in Dubaï, get your resident card.
Spend one day every 6 month there
Be tax free
US tricks Some Private banks in Geneva do have the license to manage the assets of US persons and U.S citizens. However, do not think it is a way to avoid paying taxes in the US. Opening an account at an authorized Swiss Private banks is literally the same tax-wise as opening an account at Fidelity or at Bank of America in the US. The only difference is that you will avoid all the horror stories. Horror stories are all real by the way. In Switzerland, if you build a decent case and answer all the questions and corroborate your case in depth, you will manage to convince compliance officers beforehand. When the money eventually hits your account, it is actually available and not frozen. The IRS and FATCA require to file FBAR if an offshore account is open. However FBAR is a reporting requirement and does not have taxes related to holding an account outside the US. The taxes would be the same if the account was in the US. However penalties for non compliance with FBAR are very large. The tax liability management is actually performed through the management of the assets ( for exemple by maximizing long term capital gains and minimizing short term gains). The case for Porto Rico. Full disclaimer here. I am not encouraging this. Have not collaborated on such tax avoidance schemes. if you are interested I strongly encourage you to seek a tax advisor and get a legal opinion. I am not responsible for anything written below. I am not going to say much because I am so afraid of uncle Sam that I prefer to humbly pass the hot potato to pwc From here all it takes is a good advisor and some creativity to be tax free on your crypto wealth if you are a US person apparently. Please, please please don’t ask me more. And read the disclaimer again. Trust tricks Generally speaking I do not accept fringe fiscal situation because it puts me in a difficult situation to the banks I work with, and it is already difficult enough to defend a legit crypto case. Trust might be a way to optimize your fiscal situation. Belize. Bahamas. Seychelles. Panama, You name it. At the end of the day, what matters for Swiss Banks are the beneficial owner and the settlor. Get a legal opinion, get it done, and when you eventually knock at a private bank’s door, don’t say it was for fiscal avoidance you stupid ! You will get the door smashed upon you. Be smarter. It will work. My advice is just to have it done by a great tax specialist lawyer, even if it costs you some money, as the entity itself needs to be structured in a professional way. Remember that with trust you are dispossessing yourself off your wealth. Not something to be taken lightly. “Anonymous” cash out. Right. I think I am not going into this topic, neither expose the ways to get it done. Pm me for details. I already feel a bit uncomfortable with all the info I have provided. I am just going to mention many people fear that crypto exchange might become reporting entities soon, and rightly so. This might happen anyday. You have been warned. FYI, this only works for non-US and large cash out. The difference between traders an investors. Danmark, Holland and Germany all make a huge difference if you are a passive investor or if you are a trader. ICO is considered investing for instance and is not taxed, while trading might be considered as income and charged aggressively. I would try my best to protect you and put a focus on your investor profile whenever possible, so you don't have to pay 52% tax if you do not have to :D
C. The cash out itself So you have accumulated patiently a good amount of wealth. For some of us who have been involved in crypto since 2010, it took years. Remember when BTC was stuck at 200$ for months? I personally feel like it was yesterday. There is no way you screw up your wealth by cashing out in a hurry or with low security standards. Here is how the cash out takes should place.
Full cash out or partial cash out? People who have been sitting on crypto for long have grown an emotional and irrational link with their coins. They come to me and say, look, I have 50m in crypto but I would like to cash out 500k only. So first let me tell you that as a wealth manager my advice to you is to take some off the table. Doing a partial cash out is absolutely fine. The market is bullish. We are witnessing a redistribution of wealth at a global scale. Bitcoin is the real #occupywallstreet, and every one will discuss crypto at Xmas eve which will make the market even more supportive beginning 2018, especially with all hedge funds entering the scene. If you want to stay exposed to bitcoin and altcoins, and believe these techs will change the world, it’s just natural you want to keep some coins. In the meantime, if you have lived off pizzas over the last years, and have the means to now buy yourself an nice house and have an account at a private bank, then f***ing do it mate ! Buy physical gold with this account, buy real estate, have some cash at hands. Even though US dollar is worthless to your eyes, it’s good and convenient to have some. Also remember your wife deserves it ! And if you have no wife yet and you are socially awkward like the rest of us, then maybe cashing out partially will help your situation ;) What the Private Banks expect. Joke aside, it is important you understand something. If you come around in Zurich to open a bank account and partially cash out, just don’t expect Private Banks will make an exception for you if you are small. You can’t ask them to facilitate your cash out, buy a 1m apartment with the proceeds of the sale, and not leave anything on your current account. It won’t work. Sadly, under 5m you are considered small in private banking. The bank is ok to let you open an account, provided that your kyc and compliance file are validated, but they will also want you to become a client and leave some money there to invest. This might me despicable, but I am just explaining you their rules. If you want to cash out, you should sell enough to be comfortable and have some left. Also expect the account opening to last at least 3-4 week if everything goes well. You can't just open an account overnight. The cash out logistics. Cashing out 1m USD a day in bitcoin or more is not so hard. Let me just tell you this: Even if you get a Tier 4 account with Kraken and ask Alejandro there to raise your limit over $100k per day, Even if you have a bitfinex account and you are willing to expose your wealth there, Even if you have managed to pass all the crazy due diligence at Bitstamp, The amount should be fractioned to avoid risking your full wealth on exchange and getting slaughtered on the price by trading big quantities. Cashing out involves significant risks at all time. There is a security risk of compromising your keys, a counterparty risk, a fat finger risk. Let it be done by professionals. It is worth every single penny. Most importantly, there is a major difference between trading on an exchange and trading OTC. Even though it’s not publicly disclosed some exchange like Kraken do have OTC desks. Trading on an exchange for a large amount will weight on the prices. Bitcoin is a thin market. In my opinion over 30% of the coins are lost in translation forever. Selling $10m on an exchange in a day can weight on the prices more than you’d think. And if you trade on a exchange, everything is shown on record, and you might wipe out the prices because on exchanges like bitstamp or kraken ultimately your counterparties are retail investors and the market depth is not huge. It is a bit better on Bitfinex. It is way better to trade OTC. Accessing the institutional OTC market is not easy, and that is also the reason why you should ask a regulated financial intermediary if we are talking about huge amounts. Last point, always chose EUR as opposed to USD. EU correspondent banks won’t generally block institutional amounts. However we had the cases of USD funds frozen or delayed by weeks. Most well-known OTC desks are Cumberlandmining (ask for Lucas), Genesis (ask for Martin), Bitcoin Suisse AG (ask for Niklas), circletrade, B2C2, or Altcoinomy (ask for Olivier) Very very large whales can also set up escrow accounts for massive block trades. This world, where blocks over 30k BTC are exchanged between 2 parties would deserve a reddit thread of its own. Crazyness all around. Your options: DIY or going through a regulated financial intermediary. Execution trading is a job in itself. You have to be patient, be careful not to wipe out the order book and place limit orders, monitor the market intraday for spikes or opportunities. At big levels, for a large cash out that may take weeks, these kind of details will save you hundred thousands of dollars. I understand crypto holders are suspicious and may prefer to do it by themselves, but there are regulated entities who now offer the services. Besides, being a crypto millionaire is not a guarantee you will get institutional daily withdrawal limits at exchange. You might, but it will take you another round of KYC with them, and surprisingly this round might be even more aggressive that the ones at Private banks since exchange have gone under intense scrutiny by regulators lately. The fees for cashing out through a regulated financial intermediary to help you with your cash out should be around 1-2% flat on the nominal, not more. And for this price you should get the full package: execution/monitoring of the trades AND onboarding in a private bank. If you are asked more, you are being abused. Of course, you also have the option to do it yourself. It is a way more tedious and risky process. Compliance with the exchange, compliance with the private bank, trading BTC/fiat, monitoring the transfers…You will save some money but it will take you some time and stress. Further, if you approach a private bank directly, it will trigger a series of red flag to the banks. As I said in my previous post, they call a direct approach a “walk-in”. They will be more suspicious than if you were introduced by someone and won’t hesitate to show you high fees and load your portfolio with in-house products that earn more money to the banks than to you. Remember also most banks still do not understand crypto so you will have a lot of explanations to provide and you will have to start form scratch with them! The paradox of crypto millionaires Most of my clients who made their wealth through crypto all took massive amount of risks to end up where they are. However, most of them want their bank account to be managed with a low volatility fixed income capital preservation risk profile. This is a paradox I have a hard time to explain and I think it is mainly due to the fact that most are distrustful towards banks and financial markets in general. Many clients who have sold their crypto also have a cash-out blues in the first few months. This is a classic situation. The emotions involved in hodling for so long, the relief that everything has eventually gone well, the life-changing dynamics, the difficulties to find a new motivation in life…All these elements may trigger a post cash-out depression. It is another paradox of the crypto rich who has every card in his hand to be happy, but often feel a bit sad and lonely. Sometimes, even though it’s not my job, I had to do some psychological support. A lot of clients have also become my friends, because we have the same age and went through the same “ordeal”. First world problem I know… Remember, cashing out is not the end. It’s actually the beginning. Don’t look back, don’t regret. Cash out partially, because it does not make sense to cash out in full, regret it and want back in. relax. The race to cash out crypto billionaire and the concept of late exiter. The Winklevoss brothers are obviously the first of a series. There will be crypto billionaires. Many of them. At a certain level you can have a whole family office working for you to manage your assets and take care of your needs . However, let me tell you it’s is not because you made it so big that you should think you are a genius and know everything better than anyone. You should hire professionals to help you. Managing assets require some education around the investment vehicles and risk management strategies. Sorry guys but with all the respect I have for wallstreebet, AMD and YOLO stock picking, some discipline is necessary. The investors who have made money through crypto are generally early adopters. However I have started to see another profile popping up. They are not early adopters. They are late exiters. It is another way but just as efficient. Last week I met the first crypto millionaire I know who first bough bitcoin over 1000$. 55k invested at the beginning of this year. Late adopter & late exiter is a route that can lead to the million. Last remarks. I know banks, bankers, and FIAT currencies are so last century. I know some of you despise them and would like to have them burn to the ground. With compliance officers taking over the business, I would like to start the fire myself sometimes. I hope this extensive guide has helped some of you. I am around if you need more details. I love my job despite all my frustration towards the banking industry because it makes me meet interesting people on a daily basis. I am a crypto enthusiast myself, and I do think this tech is here to stay and will change the world. Banks will have to adapt big time. Things have started to change already; they understand the threat is real. I can feel the generational gap in Geneva, with all these old bankers who don’t get what’s going on. They glaze at the bitcoin chart on CNBC in disbelief and they start to get it. This bitcoin thing is not a joke. Deep inside, as an early adopter who also intends to be a late exiter, as a libertarian myself, it makes me smile with satisfaction. Cheers. @swisspb on telegram
Colin gives a rundown on Nexus layered architecture
This is an excerpt from a much larger impromptu Q&A on Nexus Telegram, and provides an excellent overview of Nexus architecture. (edited for clarity) --------------------------------------------------------------------- Paul Screen, [10.09.19 22:03] [In reply to CryptoJoker] yes it is. There's no question that ethereum and it's direct competitors that offer turing-complete programmable contracts are very powerful. But when you actually look at the requirements of businesses trying to onboard to blockchain, we found that most of them just need simple requirements met and don't need all of the complexity and baggage that comes with it. CryptoJoker, [10.09.19 22:04] [In reply to Paul Screen] ok so ca u run only simple multi conditional transactions on the nexus VM or facebook type DAPPs on nexus ? Viz., [10.09.19 22:09] [In reply to CryptoJoker] Nah the VM is the interpreter so the language fits on top, we haven’t designed nexus to be a programming language this is an approach we didn’t agree with. It is APi based so you can code in any language and work with the functionality of the blockchain layer for what you need it to do. No you can’t port EVM code into Nexus CryptoJoker, [11.09.19 00:22] [In reply to Viz.] when you make an api request, does this result in computations done on the blockchain ? Viz., [11.09.19 00:23] It depends on the API request, if you do let’s say users/list/notifications then no as this is reading data, but finance/credit/account would since it broadcasts a transaction with OP::CREDIT CryptoJoker, [11.09.19 00:24] [In reply to Viz.] ok thanks , and can you provide me an idea of the flexbility of the VM on nexus ? can it run like facebook type dapps for example ? Viz., [11.09.19 00:28] It depends, it depends on what you want the blockchain to do and don’t. Dapp is an overused word and overstated in capability because a blockchain isn’t a computer and shouldn’t ever be, it’s a verifier. So, if you wanted to make a social network on nexus, trade tokens, chat, sure you could. A lot of functionality will be in the logical Layer as there’s no point to compute let’s say an image compression on the blockchain, you would on the logical Layer compress it, hash it, then build an object Register to hold the meta data associated with it that includes the checksum, include description. Then to update, you change the state in the object register, etc. If you wanted to do conditions in some of these interactions you could program the Boolean expression in such as, I’ll sell you this object for 5 NXS, someone is able to claim the transfer based on the condition of their debit, so on. CryptoJoker, [11.09.19 00:29] [In reply to CryptoJoker] how does the functinonality of the nexus scripts compare to that of bitcoin scripts ? is it fair to assume this: bitcoin scripting < nexus scripting < ethereum type smart contracts ? it seems like its mostly built to handle only transactions ... Viz., [11.09.19 00:31] [In reply to CryptoJoker] Not really, our architecture is completely different, hard to compare functionality. Let’s just say bitcoin scripts are slow, clunky, and stack based and only handle a Boolean expression to spend inputs, ours is a register based system with primitive operations and conditions that all interact to provide contract functionality Viz., [11.09.19 00:31] [In reply to CryptoJoker] You miss what the term register means then And “programmable data structures” CryptoJoker, [11.09.19 00:31] [In reply to Viz.] yes, this is the first time i am encountering this i also dont have a programming background unfortunately Viz., [11.09.19 00:33] A register is a structure that on hardware is what your cpu uses to store numbers in low latency memory (close to the CPU in its internal cache).... hang on, switching to computer... CryptoJoker, [11.09.19 00:34] [In reply to Viz.] ok this is all fine and good, but i guess for a layman like me i just wanna know what its functionalities are in comparison to EVM type VMs ... what can it do in comparison to EVMs, and is it fasteslower, more expensive/cheaper ? Viz., [11.09.19 00:36] Let me explain it like this: Ethereum is like everything put in one bucket, it has a turing complete byte code because they imagined you could program it like a universal computer. The reality is though, that most people abstract away from the EVM and use it for pure data storage, or managing accounts and tokens. They include operations like EXP for example, and use what is termed "Big Numbers" which are numbers that are in the range of 2^256 which is a number with over a hundred zeros. This has led to significant bottlenecks, and little value in being turing complete even though this was their value propositiion. Viz., [11.09.19 00:36] Now we get to Bitcoin, which was deliberatly not turing complete, and its scripts were designed to control the conditions on spending inputs in the UTXO model, in which it has proven useful, and some scripts such as OP_RETURN have allowed people to store data on it, but then again it aws not useful for much more than that. Viz., [11.09.19 00:37] Then we get to us, think of us between bitcoin and ethereum, but building contracts to act like contracts between people, rather than computer code. Viz., [11.09.19 00:41] So think of us as a blend of the two concepts, but in a way that is practical and useful for developers. From my research of talking to many companies that were using blockchain, I deduced a simple common denominator: nobody used ethereum for the turing completeness, they used it to store data. This was the foundation of the architecture that I developed for tritium that is a seven layer stack. So I'm going to break this down, and hope this communicates how it functions to create smart contracts or dapps in just about any capacity that's needed: Viz., [11.09.19 00:41]
Network - this is responsible for end to end communication between nodes, handling the relaying and receiving of ledger level data
Viz., [11.09.19 00:43]
Ledger - this is responsible for ensuring all data is formed under consensus and is immutable by nature. This is where your 'sigchain' or blockchain account exists. A sigchain is a decentralized blockchain account that allows you to login from any node with a username, password, and pin without the need for wallet.dat files or constantly rescanning the database. This is an important piece to how the layers above work as well, think of it as a personal blockchain that allows decentralized access through the login system that does not store any credentials, but rather deterministically creates a 'lock' mathematically that only your credentials can unlock, using a few different cryptographic functions I won't name here
Viz., [11.09.19 00:46]
Register - this layer is the data retention layer, or the layer that stores information relating to users. A register takes two forms: state and object. A state register is jsut a simple register that can store data in any sequence with no formatting enforced by the ledger. This would be for applications that have a state they want to remain immutable whih they can record in a state register. The second form is an object register, which is a programmable data type. What this means is that I can specify the fields of this register, and set some of the fields to be mutable or immutable such as lets say S/N would be immutable, but notes mutable. This allows objects to take the form much like a struct or class in object oritented languages, that can be accessed by any node, and only written to by the owning sigchain. Now registers sit on top of the ledger, and they can be transferred between sigchains or users, allowing them to take a natural form as assets or simple objects that would be included in a decentralized application such as a crypto kitty, or a post yoj make on social media, etc. This layer is responsible for managing all these states and ensuring the specified fields in these states are immutable, while other fi9elds can be updated like a program would do as it operates.
Viz., [11.09.19 00:51]
Operation - this layer is what gives context to a register and causes some action to take place. It includes two aspects to this layer, Primitive operations and Conditional operations. A contract object is a self contained object containing: a register pre-state (the register that is being operated on), a primitive operation (only one primitive operation per contract), and a set of conditions (any amount of conditional ops may be used for a fee of course). The primitive operations are basic ones like WRITE, APPEND, DEBIT, CREDIT, TRANSFER, CLAIM, CREATE, AUTHORIZE, TRUST, CONBASE, GENERATE. Each of these has a specific operation on the register it is initiated in. This is how you would maintain the state of a decentralized app, lets say crypto kitties, you have an object register that you create with OP::CREATE that has a specific meta data format associated with it, you then OP::TRANSFER it to someone else, but you gie a condition saying they must send 500 NXS beforehand, and this is the stiuplation of the TRANSFER being CLAIMABLE. When this ondition is satisfied you are able to claim the other point allowing for forms of exhange. Other stipulations or conditions could be arbitration, escrow, etc. Conditions are when there is an interaction between two actors or sigchains, which happens with a DEBIT or TRANSFER. Otherwise the other primitive oeprations act on the register such as changing its state.
Viz., [11.09.19 00:52]
API - This layer is responsible for giving an interface for the programmer to build their DAPP. This gies them direct access to login, create registers, create accounts, send coins, read data, manage notifications, etc. This is the layer develoeprs will interact with when building applications.
Viz., [11.09.19 00:53]
Logical - This is the first 'developer' layer, menaing that this is the layer that will give most of the logic to the application. This coudl be simple things like, send message to this user if they have this object that has a value of 'you're my friend' ,or antything else. This layer is the 'backend' of the dapp, and what provides a lot of the functionality. States can be read and written into the register layer, information from the ledger can be shared, stipulations on interactions can be applied. etc.
Viz., [11.09.19 00:54]
Interface - This is the 'user' layer, where the user will interact with. This in the facebook example would be the website you go to, and all the buttons that do fun stuff. This is the last layer of the 'developer' application space.
CryptoJoker, [11.09.19 00:54] thank you big applause!!!! CryptoJoker, [11.09.19 00:56] ok so to summarize my understanding of this 3 allows for creation and transfer of digital assets/objects 4 governs the operations that on objects in 3 5 interface between dapp logic and registeoperations layer
this is where the "dapp" is written by developers
am i right ? Viz., [11.09.19 00:57] So as you can see, all these layers together are what form the foundation of a dapp, with the blockchain doing some things, the application does other things. They togheter give the blockchain scability and easy to build on, and also give the appliation powerful tools to utilize. For example of an object register, your NXS account. It contains fields identifier and balance. The identifier identfies the token's contract-id or object register, and the balance keeps track of how much you have at stake. Object registers can be polymorphic though, so you can create an object register with tehse two base types, but add, notes, which you could fill with personal notes and the DEBIT and CREDIT operations would process it off of the base object, or the account menaing that you can expand from these basic objects and create many different types and uses, creating object oriented and polymorphic behavior Viz., [11.09.19 00:57] 3 is simply where they are store, it takes 4 to create the object 5 yes 6 yes plus 7, the dapp space is layers 6 and 7 together. If the dapp developer is really good though, they make custom API's with more complex contracts under the hood to provide additional functionality to their dapp, but we currently abstract the developer away from this to prevent them making mistakes that could lose people a lot of money CryptoJoker, [11.09.19 00:59] whereas for the EVM, 3,4,5,6 and 7 are all bundles into one entitiy, am i right ? Viz., [11.09.19 00:59] And last note, on layer 4, the conditional statements. These also operate on a register based VM that processes the conditional statements, and they can be grouped with as many different conditions as desired, so they can grow into quite complex contracts like we would see with legal contracts. Viz., [11.09.19 01:00] EVM doesn't really have layers It's just EVM opcodes, and then the compiler for solidity which creates the byte code, so maybe two layers Same with bitcoin scripts But bitcoin scripts dont have a compiler that creates the byte code so you have to program it as a type of assembly Viz., [11.09.19 01:01] So long story short is, our techniques and architecture are quite unique, and designed around years of market research to ensure that it was built as something that people could use easily, but also powerful enough to power the dapps people want to see Viz., [11.09.19 01:03] The login account is really important for adoption in my opinion, because users having to manage keys wont bode well for applications that expand, lets say like supply chains or other mobile applications. Managing keys in a file on your computer I think is a big hurdle to mainstream adoption, the other one is the complexity of EVM and how little practical appliation it has, even though it contains a lot of functionality, most of it us unused or abstracted away from
I'm not at all on top of my incoming messages, so in an attempt to stem the flood and address most of them, here's the current contents of my head. I feel some are using our rise to illustrate the absurdity of cryptocurrency pricing (http://uk.businessinsider.com/dogecoin-cryptocurrency-has-market-cap-above-2-billion-2018-1 for example). To me, in an environment where a cryptoasset with $30 USD equivalent transaction fees has a market cap of over a quarter of trillion dollars, I don't think we're the absurd one. Yes we take ourselves less seriously, but that doesn't mean we're not serious behind the scenes. We're a 4 year old currency with transaction fees barely over a cent and significantly higher throughput than most other cryptocurrencies. That said, now is not the time to pat ourselves on the back, 1.14 needs shipping and we need wider adoption. If you run a service/store, please look into taking Dogecoin. If you don't, please talk to others about how you can help them accept Dogecoin (DO NOT just flood them with emails saying they should, but ask why they don't and what you can do about it). On that note, lets talk structure of Dogecoin for a second. A lot of people presume Dogecoin is managed by a single coherent entity - this is very much not the case. The founders, current developers, reddit moderators, IRC, social and other teams behave as loosely coupled teams, with our own projects. We talk frequently, but there's no single leadership structure. In common with Bitcoin we have a post-launch dev team; we are not those who decided to launch a coin (that's Jackson & Billy), we saw Dogecoin as it was and decided it was something we wanted to be involved in. We're also not those who missed out on Bitcoin, I was in Bitcoin in 2011, but I didn't believe in how it was designed. As a consequence of this, "Why is no-one doing ?" generally boils down to either "We like it this way" or "Why aren't you doing ?". Most crucially; we're not taking the inflationary coins away because they're why we're in Dogecoin. I said I was in Bitcoin in 2011, and the reason I didn't stick with it is I don't believe in deflationary currencies. Even if we did, we'd have to somehow convince the miners to mine a coin where they weren't paid (which is what the inflation pays for), so the realistic scenario is an inflation-less Dogecoin would either have no miner adoption, or fees matching Bitcoin. This is typically where someone says something about their investment in Dogecoin. I really can't advise on investments, I bought Bitcoin in 2011 and sold early enough on that I'm typing this from my bedroom rather than a beach, so you probably shouldn't listen to me. I will however say that the developers have a lot less Dogecoin than virtually anyone thinks, and certainly the next dev fund payout is likely to be a significant multiple of my personal holdings, simply because we're post-launch so we've had to buy our Doge the way everyone else had to buy or mine. What else... Nodes - I've added a new permanent node in LA, and I'm bringing additional nodes up in Ireland and Seoul now. A bootstrap.dat torrent is being worked on right now, which should help too. If you're running a node please note:
It really needs to be kept online, to ensure it's actually relaying more data than it's consuming
If you can open port 22556 to the world, please do so, it will vastly improve the number of nodes that can connect to you
It's full nodes (those running Dogecoin Core) we need, leaving Multidoge/Android wallet/etc. open doesn't help us very much
1.14 will also significantly improve performance, and is making nice progress. Fees are my next task after this post, and then there's a lot of small items to address, but I'm hoping to get an alpha out shortly. Also I haven't broken testnet yet, which is a nice change compared to 1.10! We aren't about to introduce paying nodes because it's essentially technically impractical. This could either come from mining rewards (and you can fight either the miners or those who we create too many coins already, for that), or from other receiving nodes themselves. If it's from mining then somehow we'd have to identify contributing nodes, if it's from receiving nodes I'm not sure people are going to be happy with their balance dropping due to network usage. Although it might be a break-even I suppose. Generally, though, paying nodes is called proof of stake, and that's a whole different discussion. Someone asked about the website - it's being discussed, let me get back to you. Please treat your Dogecoins and wallet files like you would cash. We can't get them back for you if you send them to the wrong person (if we could, we'd have raided the Dogeparty address and be retired on a beach by now). Keep backups, and never delete old wallets (you never know when you might need a random key from an old wallet). Full list of changes in 1.14 is coming (although generally if it's in Bitcoin Core 0.14, expect to see it in), but the highlight for me beyond the improved performance is hierarchical deterministic wallets, which mean restoring old wallet backups will recover more recent funds. That should save a lot of lost funds, I hope! Last one, quick list of Twitter accounts to follow:
