Signet

This is a description of how to get started with Signet. This document assumes you are capable of using git, and that you are able to compile Bitcoin. (If you have not yet done so, you should begin by doing that now.)

Fetch and compile signet

$ git clone https://github.com/kallewoof/bitcoin.git signet
$ cd signet
$ git checkout 2003-signet-consensus

Setting up Clang Static Analyzer on macOS

• Go to https://clang-analyzer.llvm.org/
• Grab the checker-279.tar.bz2 file from the link under Mac OS X
• Untar this file somewhere, e.g. ~/workspace/checker-279

Using it

• Go to e.g. ~/workspace/myproject
• Compile it from scratch, including autogen parts, with make clean, but prefix each call with the scan-build in the path above. E.g.

Schnorr signature test vectors

Test vector overview

1. Hash function H(m) = SHA256(m)

Basics

• For a private key x, the public key is xG.
• A signature on the message m with private key x is (R, s) where R=kG, s=k+H(R,X,m)x.
• Verifying a signature is testing whether sG = R+H(R,X,m)X.
