Arbitrum, the largest Ethereum layer-2 scaling solution by total value locked (TVL), is taking steps towards decentralization. In an update on April 16, Offchain Labs–Arbitrum developers–said they have deployed the permissionless version of their fraud proofs, dubbed Bounded Liquidity Delay (BOLD), to testnet.
Ethereum Layer-2s Are Popular, But There Is A Big Problem
Ethereum layer-2 solutions have been gaining prominence over the years. According to L2Beat data on April 17, these platforms control over $37 billion of assets. Protocol developers and users can send transactions cheaply through Arbitrum, Optimism, Base, and other alternatives.
However, while they are popular and command billions in TVL, most of these platforms’ fraud proofs are being developed. Typically, when users transact all chains, all transactions must be confirmed by a web of miners or validators, depending on the consensus mechanism.
This differs in layer-2 options, which must reroute trans
