Another promise of sidechains is the ability to have a stronger and faster mainchain, as transactions can happen on one of the sidechains. If users or developers are dissatisfied with the costs of sending a transaction and the transaction speed of the mainchain, they can use and or deploy their dapp on one of the sidechains. This leads to a more diversified network and a stronger, faster and more robust mainchain.


Now, making experimental or rapid changes to Bitcoin is very risky and so change happens slowly. So if the one-size-fits-all architecture of Bitcoin doesn’t suit a particular use-case, you have a problem. You either have to use an entirely different cryptocurrency (or build one!). Or you have to use (or build) a centralized service, which brings new risks.

A company called Blockstream has been focusing on these developments and has announced the release of Sidechain Elements, which is an open-sourced framework for sidechain development. It includes a functioning code and a testing environment for working with sidechains with several components: the core network software to build an initial testing sidechain, eight new features not currently supported by bitcoin, a basic wallet and the code for moving coins between blockchains.
Private blockchains are valuable for solving efficiency, security and fraud problems within traditional financial institutions, but only incrementally. It’s not very likely that private blockchains will revolutionize the financial system. Public blockchains, however, hold the potential to replace most functions of traditional financial institutions with software, fundamentally reshaping the way the financial system works.
Note: Some would argue that such a system cannot be defined as a blockchain. Also, Blockchain is still in it’s early stages. It is unclear how the technology will pan out and will be adopted. Many argue that private or federated Blockchains might suffer the fate of Intranets in the 1990’s, when private companies built their own private LANs or WANs instead of using the public Internet and all the services, but has more or less become obsolete especially with the advent of SAAS in the Web2.
There has been tremendous interest in blockchain, the technology on which Bitcoin functions. Nakamoto developed the blockchain as an acceptable solution to the game theory puzzle – Byzantine General’s Problem. This lead to a number of firms adopting the technology in different ways to solve real world issues, wherever there was an element of trust involved. Majority of them could be relating to the ability to provide proof of ownership – for documents, software modules/licenses, voting etc.
This is what, at its core, state channels are. Imagine we wanted to play a game of Starcraft and have a smart contract that pays 1 ETH to the winner. It would be ridiculous for each participant to have to write on the main Ethereum network each time a Zergling was killed by a Zealot, or when a Command Center was upgraded to an Orbital Command. The gas cost (Ethereum gas, not Starcraft gas) and time for each transaction would be prohibitive.
A blockchain is so-called “public” (or open) when anyone can become a member of the network without conditions of admission. In other words, anyone wishing to use the service proposed by the network can download the protocol locally without having to reveal his or her identity or meet predetermined criteria. A protocol is a computer program that could be compared to a Charter in that it defines the rules of operation of a network based on a blockchain. For example, the members of the bitcoin network download the Bitcoin protocol (through the intermediary of their “wallet”) to be able to join the network and exchange bitcoins, but the only condition is to have an Internet connection.
@gendal I am discussing private chains with prospects, so my interest is not superficial and theoretical. I see the benefits for the organization in using the private chain as another form of internal database, with better security properties. It can also be used where a service bus product would be today, to facilitate integration, conformance, monitoring, audit. Private chain can also, via a two way peg, be connected to the main chain, achieving a form of public/private network divide that routers created for us in the early stages of the Internet development. Anything else on the benefits side that I missed?

“Further, contribution is weighted by computational power rather than one threshold signature contribution per party, which allows anonymous membership without risk of a Sybil attack (when one party joins many times and has disproportionate input into the signature). For this reason, the DMMS has also been described as a solution to the Byzantine Generals Problem[AJK05].”


Security: RSK´s blockchain is secured by merge-mining, which means that they can achieve the same security as Bitcoin in terms of double-spend prevention and settlement finality. The 2way peg security will first rely in a federation holding custody of bitcoins, and later switch to an automatic peg, when the community accepts the security trade-offs of the automatic peg.
A diferencia con la, hasta ahora, plataforma estrella de smart contracts Ethereum, otra de las diferencias más importantes de Lisk es que, en Lisk, cada aplicación corre sobre su propia sidechain y no sobre una única cadena, cómo es el caso de Ethereum. Por lo tanto, un entorno propio e independiente que podrá exprimir cada desarrollador para cada DAPP desarrollada con un backend en JS/NodeJS y un frontend HTML/CSS/JS.

Anyway, new blocks do not appear on the blockchain all of a sudden – the network must achieve consensus. In other words, each transaction must be validated by the rest of the network members, so-called “nodes.” Their contribution to the final decision on consensus is equal. Each node solves a complex cryptographic problem, and when a solution is found a new block appears on the blockchain. Such algorithm is called “proof-of-work consensus protocol.”

An important distinction to be made about sidechains that needs to be understood is that sidechains themselves help to fuel innovation through experimentation. Rather than providing scalability directly, they allow for trivial experimentation on sidechains with various scalability mechanisms. Using sidechains, one can avoid the problems of initial distribution, market volatility, and barriers to entry when experimenting with altcoins due to the inherent derivation of their scarcity and supply from Bitcoin. That being said, each sidechain is independent and flexible to tool around with various features.
Cabe destacar el papel de la gente de Blockstream, una de las compañías centradas en la búsqueda de este objetivo (con un extremeño en sus filas, Jorge Timón). Blockstream está trabajando actualmente en el desarrollo de un protocolo que permita crear sidechains. Son los responsables de uno de los papers más conocidos sobre el tema, publicado en Octubre del 2014:
Because decentralization has been viewed by many as intrinsic to the revolutionary potential of blockchain, the point of private blockchains might be called into question. However, blockchains offer much more than a structure that accommodates decentralization. Among other features, their strong cryptography and auditability offers them more security than traditional protocols (although not bulletproof, as noted), and they allow for the development of new cryptocurrencies. Furthermore, voting platforms, accounting systems, and any type of data archive can arguably be optimized with blockchain technology. We are still in the early days of blockchain technology, and the power it has to reshape older systems has yet to be seen.
A partir de este momento, se podrán intercambiar y mover estas monedas para hacer uso del potencial de esa sidechain siguiendo las directrices y protocolo que ésta tenga estipulado. Por ejemplo, quizá la velocidad de creación de los bloques es más rápida en esta o quizá los scripts de transacción en esa cadena son turing completos (disponen de un poder de cómputo equivalente a la máquina universal de Turing).

The network's 'nodes'—users running the bitcoin software on their computers—collectively check the integrity of other nodes to ensure that no one spends the same coins twice. All transactions are published on a shared public ledger, called the 'block chain.'
