This repository contains Guix attestations for releases of Bitcoin Core.

Overall process

The Guix build consists of two stages:

• In the first stage (noncodesigned), people compile the binaries from source.
• Then, code signatures for Windows and MacOS are generated from the binaries that were produced in the first stage, and distributed to the builders.
• In the second stage (all), the builders attach these code signatures.

See https://github.com/bitcoin/bitcoin/blob/master/doc/release-process.md#building on how to build the release with Guix and create an attestation.

Directory structure

• /<version>/<signer>/: Build attestations for repository tag v<version> for <signer>.
  • noncodesigned.SHA256SUMS: Hashes of binaries produced by the first stage build for this version.
  • noncodesigned.SHA256SUMS.asc: Detached PGP signature for noncodesigned.SHA256SUMS.
  • all.SHA256SUMS: Hashes of binaries produced by the second stage build. This covers all the binaries uploaded to the website, and is what to check release binaries against.
  • all.SHA256SUMS.asc: Detached PGP signature for all.SHA256SUMS.
• /builder-keys/<signer>.gpg: PGP keys of the signers. If you're going to do builds and contribute attestations, file a PR to add your key here.
• /contrib: Scripts used in the CI tests.
