Why use blockchain for Certificates of Authenticity?
Blockchain technology lets us create permanent certificates that can be publicly verified while still protecting the privacy of owners, buyers and sellers.
The blockchain is a public record so anybody can verify the existence of a certificate and check provenance instantly if they have access to the certificate. However, the identity of key parties and transactional details can be kept out of public view.
Each blockchain record is tamper-proof which ensures your certificate timestamps are securely and permanently recorded.
The combination of security, transparency and anonymity provided by the blockchain enables the certification and verification of your data without the risk of corruption, loss or expiry protecting your records of creation and ownership.
How do certificates use blockchain?
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 (creators, issuers and owners). These prove which creator 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. 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"
