What is an SBIX Certificate?

An SBIX certificate is an immutable cryptographic proof of a document's existence at a specific point in time. It combines a SHA-256 fingerprint, a Merkle tree proof, an Ed25519 signature, a legally-recognised RFC-3161 timestamp, and dual blockchain anchoring on Tezos and Aleph Cloud.
