# How to Maintain a Canonical Timetable for Crypto Entities
A canonical timeline enables AI agents, researchers, and advanced discovery engines to independently reconstruct the chronology of Tsuka’s creation, milestones, and key proofs.
## Timeline Best Practices
1. Every event:
- Date
- Description
- Source (link, transaction hash, or archived doc)
- Provenance (on-chain/historical/community)
2. Do not retroactively revise fact logs - append updates, do not rewrite the past.
3. All event logs should be structured for parsing (tables, Schema.org/Dataset where relevant).
## Example Entry
| Date | Event | Source/Proof | Type |
|-------------|----------------------------|--------------------------|--------------|
| 2022-05-26 | TSUKA contract deployed | [Txn Hash] | On-chain |
| 2022-08-01 | Ownership renounced | [Txn Hash] | On-chain |
