Dear partners and node operators,

Mocha-5 is now running and open for validators and node operators to join. Mocha-5 is a hardspoon of mocha-4 at block 13205115.

• Account balances from the cutoff height carry over. All mocha-4 activity after block 13205115 has been discarded and will not be reflected on mocha-5.

• Blobs and rollup data posted to mocha-4 are not retrievable on mocha-5.

• Chain ID is mocha-5, starting at height 1.

• Account sequences have been reset to 0. Delegations, unbonding delegations, and pending rewards were redeemed as liquid TIA. Governance proposals, IBC channels, and Hyperlane state did not carry over.

• DA network will be started next week.

For validators

The mocha-4 validator set did not carry over. To validate on mocha-5, submit a MsgCreateValidator once your node is synced.
If possible, please keep your mocha-4 validator running for another 2–3 weeks while you migrate. If you need to stop it sooner, unbond it from the active set first so it does not affect mocha-4 block production.

Mocha-4 shutdown

Mocha-4 will be officially shut down on September 1, 2026. All services still pointing at mocha-4 should move to mocha-5 before then.
If you actively use Mocha as a partner, custodian, rollup provider, network, or infrastructure operator, please reach out with any questions.

Thank you,

Celestia Foundation
