The proposal to bring permissionless transaction verification to Arbitrum passed the temperature check vote today (14th), which means that the Ethereum Layer 2 network with the highest TVL (Total Locked Value) is currently implementing Stage 2 Rollup. Another step on the road.

Following the passing of this vote, Arbitrum is expected to propose a governance proposal to upgrade its smart contracts to adopt BOLD. BOLD is a new dispute resolution protocol that enables anyone to become a validator on Arbitrum and enhances the security of the Arbitrum chain by reducing the risk of latency attacks. Validators validating withdrawals from Arbitrum to the Ethereum base layer are currently limited to a permission list.

Arbitrum’s proposal reads:

“Securing Arbitrum One and Nova through this AIP and implementing BOLD effectively enables permissionless verification, marking a key milestone for the Arbitrum chain to be recognized as Stage 2 rollups and part of Arbitrum’s comprehensive decentralization journey.”

BOLD was launched on the Arbitrum testnet in April this year. If the proposal is approved by the ArbitrumDAO, BOLD is expected to be implemented on Arbitrum One and Nova at some point in summer 2024.

Competitor Optimism, which also uses Optimistic rollups, has recently released fault proofs on its second-layer blockchain OP Mainnet, allowing it to advance to Stage 1 Rollup in terms of decentralization like Arbitrum.
