Verisart uses blockchain technology to create permanent certificates that can be publicly verified while still protecting the privacy of owners, buyers and sellers.
Events like the creation or transfer of a certificate are registered by time-stamping the blockchain ledger.
The data on your certificate is permanently registered on the Bitcoin blockchain, specifically, we use OpenTimestamps to timestamp provenance. The creation and any subsequent updates to the certificate are timestamped, added to the blockchain and captured in the history of the certificate.
The certificate data, including files and metadata, are stored in a cryptographically signed format on our systems. This combined data is then linked to a timestamped provenance record on the bitcoin blockchain.
We also create digital signatures using public keys owned by various parties involved in a certificate (artists, issuers and owners). These prove which artist created a certificate, who issued the certificate, and who owned the certificate during its life.
You can download a permanent archive of your certificate, which can be independently verified by checking the blockchain record, and the digital signatures against. These checks can be done without Verisart's assistance.
To download the archive file, find the desired certificate in your dashboard, click the download icon and select "archive"
