Prevent stale Cardano registry metadata from replacing a newer property
An off-chain metadata registry can deliver updates in a different order from publication. CIP-26 provides sequence information for each entry to help clients detect older data.
Track each property independently
Key cached records by subject and property. Compare the incoming sequence number with the stored number for that same property. Preserve any signatures and validate them according to the registry’s authority policy.
subject X, property name, sequence 5 → cached
subject X, property name, sequence 4 → older
subject X, property description, sequence 2 → independent
In this example a name with sequence 4 cannot advance the cached name at sequence 5. A description at sequence 2 is a separate property and must be compared with the previous description, not with the name.
Keep registry data out of ledger accounting
A display name or description is off-chain metadata. Its update does not change asset balances or minting policy. If two sources present conflicting values at the same sequence, retain the conflict and verify origin before replacing the displayed value. cips.cardano.org Cardano CIP-26
