Ponder has a permissive file on record. That is not a cleared export. Non-commercial or demo use does not remove the licence duty. When in doubt, link — do not copy.
Use
- A read model of public chain events you are allowed to index
Do not use for
- A system of record for legal title
- Private personal data
Risks
- A reorg can rewrite recent events. The read model needs a finality rule.
- Indexing public data can still create a privacy problem if you join it to identities.
Reviews required
- What you store, and for how long
