Stellar is used as an integrity and attestation layer. TUGMA publishes only a cryptographic fingerprint of a finalized evidence package so its integrity can be independently verified.
Step 1
A finalized, immutable set of control evidence assembled for a period.
Step 2
The package is serialized into a canonical form and hashed with SHA-256.
Step 3
The hash — never the underlying data — is attested to the Stellar test network.
Step 4
Anyone can re-hash the package and compare it against the attested fingerprint.
Sensitive payment and customer information is never written to any blockchain. Only a hash is attested.
If a single byte of the evidence package changes, its hash changes and verification fails.
This is a prototype on the Stellar test network. It does not imply mainnet production readiness.
