Yes. EMOZ uses public blockchains (e.g. Polygon, Polygon-Amoy) to record structured data, making it functionally equivalent to a decentralized electronic ledger. Each record written via a smart contract includes:
An immutable transaction containing a SHA-256 file hash and encrypted metadata.
A verifiable, timestamped sequence guaranteed by the blockchain’s structure.
Cryptographic integrity: changes would break the chain, making tampering instantly detectable.
EMOZ does not control the ledger (i.e. the blockchain): it uses it as a third-party decentralized record-keeping system.
