Schnorr Signature Algorithm to Increase Bitcoin Scale and ...

Bitcoin transactions must necessarily be accompanied by signatures.

By using the Schnorr protocol to limit the number of signatures needed for a transaction, it would be possible to help, in part, Bitcoin to cope with the increase in its popularity.

Technology roadmap - Schnorr signatures and signature ...

The replacement of Bitcoin's digital signature algorithm (ECDSA) for the more efficient Schnorr algorithm has long been at the top of the wish list for many Bitcoin developers. A simple algorithm leveraging elliptic curve cryptography, Schnorr enables several improvements over the existing scheme all while preserving all of its features and security assumptions.

Notably, Schnorr signatures support "native multisig" which enables the aggregation...

Six Things Bitcoin Users Should Know about Private Keys ...

Private keys have been an integral component of Bitcoin since its first description in 2008. Wallet software often attempts to shield users from the need to understand what private keys are and how they work. Even so, most users eventually come face to face with private keys, too often with unpleasant results.

A basic understanding of private keys can help prevent loss of funds and other mishaps,...

Bitcoin Core Roadmap Hints at Schnorr Signatures To Reduce ...

Even though there is a ton of focus on Bitcoin Core vs Bitcoin unlimited right now, there are other things to keep an eye on as well. The Core developers released a new roadmap last night which offers some interesting concepts. Perhaps the biggest change is how digital signatures will be changed to a more sophisticated algorithm. This will also help decrease the amount of data found in the...

Mastering Bitcoin – O’Reilly Media

Ownership of bitcoin is established through digital keys, bitcoin addresses, and digital signatures. The digital keys are not actually stored in the network, but are instead created and stored by users in a file, or simple database, called a wallet. The digital keys in a user's wallet are completely independent of the bitcoin protocol and can be generated and managed by the user's wallet software...

The Cryptography of Bitcoin

It is actually surprisingly difficult for a layperson to find out precisely what cryptography Bitcoin uses, without consulting the source of Bitcoin directly. For example, the opcode OP_CHECKSIG , ostensibly checks the signature of something... but there is no indication what kind of signature it checks! (What are opcodes in Bitcoin? Well it turns out that the protocol...

Elliptic-curve digital signatures - Davide De Rosa

See on Github

Now that you're able to generate EC keypairs, the next step is using them to sign and verify messages. By message I mean any data -from text to binary- that needs to be authenticated. Specifically, Bitcoin clients produce signatures to authenticate their transactions, whereas miners verify such signatures to authorize and broadcast valid transactions.

This post is going to deal with...
