SeedHammer is a metal engraving machine for bitcoin used for creating robust singlesig/multisig with mnemonic seed, descriptor and QRs. This update concerns SeedHammer source code, which is used to run the controller program for the SeedHammer machine.
"We have now officially released v1.0.0 of the SeedHammer software!"
"We now have reproducible builds and no more known software security issues."
"It took some to achieve bit-for-bit reproducible builds because:
1) We wanted reproducibility across all four combinations of macOS/Linux and Intel/M1. 2) nixpkgs does not have bit-for-bit reproducibility as a goal. We had to do PRs in order to obtain this. 3) Nix development was frozen around their 23.05 release in May. So our PRs couldn't get merged before that."
"So in essence this release doesn't really do much in itself, however it enables the community to help keep the builds honest."
Reproducible builds. "This release, and all future releases, should produce images that matches our official releases bit-for-bit. Look for "Reproducible builds" in the README for instructions." - "Reproducible builds was the single remaining security issue (the other being constant time engraving), so we feel confident in making this release v1.0.0."
Minor changes. "This release also restores version numbers on the main screen which was accidentally broken in the previous release."
