Merged Mining: Analysis of Effects and Implications

Date: 2017-08-24
Author(s): Alexei Zamyatin, Edgar Weippl

Link to Paper


Abstract
Merged mining refers to the concept of mining more than one cryptocurrency without necessitating additional proof-of-work effort. Merged mining was introduced in 2011 as a boostrapping mechanism for new cryptocurrencies and countermeasures against the fragmentation of mining power across competing systems. Although merged mining has already been adopted by a number of cryptocurrencies, to this date little is known about the effects and implications.
In this thesis, we shed light on this topic area by performing a comprehensive analysis of merged mining in practice. As part of this analysis, we present a block attribution scheme for mining pools to assist in the evaluation of mining centralization. Our findings disclose that mining pools in merge-mined cryptocurrencies have operated at the edge of, and even beyond, the security guarantees offered by the underlying Nakamoto consensus for extended periods. We discuss the implications and security considerations for these cryptocurrencies and the mining ecosystem as a whole, and link our findings to the intended effects of merged mining.

P.D2:[url]https://www.reddit.com/Bitcoin/comments/5609tu/1st_test_on_lightning_network_between_rusty/[/url] [I](primer ejemplo de lightning_network)[/I]
explicacion del video anterior: [SPOILER]Todo lo hace en la testchain de Bitcoin. Abre un canal con 0'04 testcoins y efectua el pago de 10000 milisatoshis para comprar la ya famosa imagen de los gatitos viendo la luna.
No hay transacción de vuelta, es símplemente un pago que se ha realizado a través del canal que habían abierto.
En la blockchain (en realidad, en la testchain, puesto que se está utilizando la cadena de bloques para pruebas que tiene Bitcoin) se ha realizado una transacción, que es la transacción necesaria que hay que hacer para establecer el canal.
La transacción de compra de la imagen (la de los 10000 milisatoshis) es la que se hace fuera de la cadena de bloques.
A ver, el canal se establece por un importe de 0'04 bitcoins (testcoins, en realidad). Una vez realizada la transacción de 10000 milibitcoins en la lightning network, el balance de ese canal cambia a 0'04 bitcoins - 10000 milibitcoins.
Pero lo bueno del asunto es que el canal de pagos es bidireccional y, se supone, que formará parte de una red (la lightning network) de manera que el balance se irá reajustando conforme las transacciones de la red vayan necesitando hacer uso de dicho del canal de pago que has abierto.
Cuando cualquiera de las dos partes decida cerrar el canal, entonces el balance que contenga en ese instante será el que se fijará en la cadena de bloques.
Las transacciones que emplean el canal de pago son "off blockchain", esto es, se realizan sin necesidad de ser reflejadas en la cadena de bloques. La única transacción que ha necesitado utilizar la cadena de bloques es la necesaria para crear el canal.
El canal no se ha cerrado, ha permanecido abierto.[/SPOILER] P.D 3:

Using the Merkle Tree and root to prove transactions are in a block

Okay so I've read alot about this over the past days, including parts of the white paper, youtube videos and Wiki pages as well as different forums.
However, none of them seem to touch on how merkle trees are used for verifying transactions in practice.
Take this tree for example:
 ABCDEEEE .......Merkle root / \ ABCD EEEE / \ / AB CD EE .......E is paired with itself /\ /\ / A B C D E .........Transactions 
According to the Bitcoin developer guide, in order to verify a specific transaction D, we only need the AB, C and EEEE part. So these parts and our transaction D can be used to create the merkle root. Is that how it works?
How do I verify a given transaction in a block of say 1024 transactions? I've read somewhere that verifying is O(log(n)) for hash trees, does that mean that verifying any given transaction in a merkle tree of size 1024 is given by log(1024) =~ 3.01. I.e. 3 hashes?
Would really like some help and clarification on this! Regards.
