RegistrarController

Purpose:

Manages identity registration, renewal, and batch record updates.

Key Methods:

• makeCommitment(): Generates a commitment hash to reserve an identity.

• commit(): Finalizes the commitment.

• register(): Registers the identity after the waiting period.

• renew(): Extends the identity’s expiration duration.

• setRecords(): Batch updates resolver records (e.g., address, text, contenthash).

Events:

• NameRegistered(name, node, owner, expires)

• NameRenewed(name, node, duration, expires)

Interactions:

• Works with PublicResolver to set/update records.

• Uses PriceController to calculate registration/renewal fees.

Grace Period

Purpose: Enforces grace period rules post-identity expiration. Logic:

• After expiration, ownership is retained for GRACE_PERIOD (e.g., 30 days).

• Post-grace period, identities become available for purchase.

Interactions:

• Integrated into RegistrarController for renewal checks.
