Provenance Proof Blockchain Participants

Aiming at bringing more transparency to every step of the gemstone’s value chain, the Provenance Proof Blockchain digitally records individual peer-to-peer transactions, creating a virtual ledger secured through cryptography, which is distributed and accessible to the custodian of the gemstone.
