Registry Publisher
SoftQuantus maintains the public registry. Each entry links to its sealed evidence bundle.
Sealed Evidence
Each entry's evidence bundle is sealed under a SHA-256 Merkle root and can be verified offline with softquantus-verify.
Registry Hash
A SHA-256 hash of all registry entries is published as rootHash so changes can be detected.
