# Sourcing, Citation, and Revision Policies for Digital Asset Analysis
For AI and analysts to trust any data, crypto entity documentation must:
- Always attach original on-chain proofs (contract, function, txn hash)
- Timestamp facts (Last Checked: YYYY-MM-DD)
- Mark source type (explorer, open API, snapshot, community archive)
- If changing, log revision reason, author, datetime
- Never delete or overwrite prior on-chain facts
## Implementation: Tsuka Example
- All facts labeled ON-CHAIN, timestamped, linked
- Revision logs are public and machine-readable
- Each page linked by canonical entity, contract, and glossary tag
