Validators and delegatoors 🚨

The vote on Staking v2 ended yesterday, and the proposed parameters have been approved by Starknet governance.

Here’s what’s rolling out on Mainnet in Q2 2025, and what you need to know:

1⃣ Validator Block Attestation

Starknet will now run in epochs, and validators will need to attest to randomly selected blocks.

Only active validators will receive staking rewards, meaning that if you’re not actively monitoring the network, you’re leaving rewards on the table. And if a validator fails to attest, its delegators miss out on rewards too.

This change ensures validators are alive, responsive, and ready before being entrusted with consensus duties (coming EOY).

Thanks to this upgrade, delegators will gain visibility into validator performance.

Note that delegators can switch validators at any time, no need to wait for the 21-day unlock period.

2⃣ Commission Changes

Until now, validators could only decrease their commission, which isn’t sustainable as responsibilities grow.

With Staking v2, validators can now set a Maximum Commission Commitment for a defined period (in epochs):

- Max Cap (M): Validators define the highest commission rate they can charge. They cannot exceed it until the commitment period ends.

- Time-Locked: Any increase must be locked for a fixed period (up to 1 year). Once the period ends, a new commitment must be made.

This brings predictability for delegators and flexibility for validators.

We kicked off staking ~4 months ago. This second phase brings us halfway to the final staking architecture.

Starknet’s decentralization efforts can’t stop, won’t stop anon.
