Schema Snorri will be the biggest change Bitcoin since SegWit

Bitcoin has received one of the most important improvements last week, when an influential developer Peter Wuille opened your project from a technical point of view. Together with the presentation of ideas, it became apparent that this is one of the most important works carried out by the developers of Bitcoin in recent years. It will bring the largest cryptocurrency in the world to scale and privacy.

Another major change in Bitcoin will become Schnorr ("Knorr") — this will be the biggest change after the introduction of Segregated Witness (SegWit), correction of key errors that gave rise to a protracted battle in the community of Bitcoin last year before he eventually did.

At the technical level, adding support for "Snorre", schema, digital signatures will give users a Bitcoin new method to generate cryptographic keys, they need to store and send bitcoins. Thus also making the way for a number of impressive additions, including addressing the issues of scalability and privacy, two of the most annoying problems of Bitcoin.

"This is the cornerstone of a number of improvements," said Vuille, adding that there will be other, not yet obvious changes in the future. Although Vuille hopes that this change will be ultimately made, the decision "remains with the users." If we want to accept it, we accept, as was the case SegWit.

New technical, mathematically complex sentence describes the exact signature scheme, which can be coded in Bitcoin. And although the end goal is far away, this is an important and necessary step on the way to it.

One of the authors Jonas Nick says that "standardization Snorra Bitcoin is an important step to using it [the scheme] in Bitcoin".

moving forward

The Project helps to avoid confusion in the future, offering a standard that ensures that all developers and sellers eventually implement code signature Snorra the same.

Although a full description is difficult to understand, the basic idea is a mathematical necessity of the use and production of signatures (signature) Snorre, offering an alternative to the algorithm of creation of digital signature using elliptic curve (ECDSA), which produces the keys and confirms the transactions in the Bitcoin network.

The schema Snorra have one thing in common with the schemes of the signing that she wants to oust. If the plan will accept, it will use the same mathematical "curves", which uses ECDSA for the production of keys, namely "secp256k1".
In this scheme, a lot of complex mathematics, so if you are not able to understand it, just follow the ensuing discussion among developers of Bitcoin.

However, much of the negative no, and the developers are optimistic. Especially for the reason that, unlike ECDSA, the security of the scheme Snorra possible to prove mathematically. Although the scheme Snorra offers a number of improvements in itself, it also paves the way for changes that can be build on top of it, like new privacy protection technology.

Now, when users send so-called "multiservice transactions", i.e. transactions with multiple signatures belonging to two different people, it immediately becomes obvious because of the public nature of the blockchain of Bitcoin. But the scheme Snorra paves the way for a method that will make the transaction look the same as everyone else.
In addition, these extended transactions will become cheaper, and this is important, given the Commission, which greatly increases during periods of congestion.

In addition, it seems that new technologies that can be created on the basis of the scheme Snorra offered constantly.
"Because of the large number of new discoveries made in recent times, I believe that technology should be developed in stages, and personally I'll focus on the first step is Schnorr and Taproot," says Vuille, mentioning the improvement of Bitcoin "Taproot" proposed in the beginning of this year another important Bitcoin developer Greg Maxwell to further improve the privacy of Bitcoin.

Less time

Work, of course, going over the diagram of Snorra this is a massive project with many moving parts.
While the proposal for improving Bitcoin offers developers a standard from which to work, Nick says that the implementation of the code takes a very long time, so the transition from draft to implementation will occur soon. In addition, when developers make sure that no more problems, they will have to find a way to add code to Bitcoin. The specifics of the deployment schemes in Bitcoin remains under active consideration.

"As with any change consensus, it will be a long process, including development of project for integration, publication, comment from the technical community and ecosystem, writing the implementation rules of consus and integration in software obespechenie wallets, offer your deployment plan and, if all goes according to plan, activate," says Vuille, the past not one change consensus.

Scheme Snorra is a huge upgrade. Despite the fact that the most used Bitcoin client are being introduced every day and some code comes from a motley group of coders from around the world, Knorr is a rare type of change, as it affects the most important rules in Bitcoin.

SegWit was the last change that "consensus" was implemented in Bitcoin, and so gave rise to great controversy, that the dissenters created theirown cryptocurrency without SegWit.

The Most ardent supporters of the introduction SegWit even got a caps to emphasize their desire to change the code. But now, it seems that schemes Snorra more likely softer to slip into the code of Bitcoin than even the SegWit. Well, let's wait and see.
