Cryptographic Data Verification
Every data point in Avena Terminal is cryptographically hashed and publicly auditable. Verify any statistic, any time, without trusting us.
HOW IT WORKS
Data Created
Every property record, score, and statistic is processed. A SHA-256 cryptographic hash is generated from the raw data.
Hash Stored Immutably
The hash and timestamp are stored in an append-only log. No record can be altered without invalidating the chain.
Anyone Verifies
Paste any statistic or property reference to verify its integrity. The system returns a cryptographic proof of authenticity.
