EOS Amsterdam Launches Blockchain Signing Tool

Use cases

  • An EOSIO block producer publishes a snapshot of a blockchain, or archival data, and signs the files with “filehashfact”. Other block producers may verify the validity of these files and co-sign, adding more trust to the original data.
  • A software company can sign its software releases. For example, EOS Sweden is publishing its own Debian packages of EOSIO software and its modifications (such as BOS and WAX versions). Users who verified and used these packages can endorse them with their signatures.
  • An artist can claim their authorship of the artwork before it’s used for NFT images. Third party experts can verify and confirm that the artwork is original.
