WebTime stamping is an increasingly valuable complement to digital signing practices, enabling organizations to record when a digital item—such as a message, document, transaction or piece of software—was signed. For some applications, the timing of a digital signature is critical, as in the case of stock trades, lottery ticket issuance and ... WebFeb 7, 2024 · To post a cryptographic timestamp, the BSL-4 labs can simply post cryptographic hashes of all of their data on a blockchain such as the Bitcoin or Circcash blockchains. The BSL-4 lab may also post a Merkle root of this data on a blockchain so that it is possible for an entity to select and reveal specific portions of this data while …
