Certificate
On-chain X.509 certificates
The certificate transaction is part of the Palladium release.
A Certificate transaction allows an identity on the LTO Network to anchor an X.509 certificate on-chain, typically an organizational or Extended Validation (EV) certificate. This enables trusted identification of legal entities, such as companies, within decentralized workflows.
By registering the certificate on-chain, the organization’s identity can be cryptographically verified and linked to its LTO account. This serves as a foundation for verifiable credentials, cross-chain identity proofs, and secure interactions in regulated environments.
