Chaucha Commit Notarization

Using Chaucha blockchain, commits can be certified using OP_RETURN. Now Github history can be notarized.

Usage

Using a mixture of OP_RETURN and Git Notes we can notarize each commit.

          sendkey: "${{secrets.SENDKEY}}"
          message: "repo: ${{github.repository}};branch: ${{github.ref}};commit: ${{github.sha}}"

      # Save certification using git-notes
