Arbitrum Technical Roadmap

Offchain Labs, the team behind Arbitrum AnyTrust chains, released a technical roadmap outlining progress on decentralization, interoperability, scaling, and performance. Stylus, a programming environment for writing smart contracts using WASM, is set to go live on Arbitrum One on September 3rd. In Q3, Arbitrum will introduce fast withdrawals, allowing AnyTrust chains to settle to their parent chain within minutes. In Q4, Arbitrum will launch BoLD, a dispute resolution protocol, on the mainnet. Looking ahead to 2025, Offchain Labs plans to roll out multi-client support, dynamic gas pricing, and chain clusters, and potentially decentralize the Arbitrum sequencer. Offchain Labs is also researching the integration of ZK tech into Arbitrum.

Bolt Protocol Alpha Release

Bolt Protocol released an alpha version of its transaction preconfirmation system, enabling sub-second confirmations for most transactions. The system allows Ethereum block proposers to make credible, trustless commitments about the transactions they include in their blocks, enhancing the user experience. The implementation supports transaction pre-confirmations that are faster than Ethereum's 12-second block time. The system also ensures that proposers are held accountable by enforcing penalties if they breach their commitment. Bolt Protocol is fully open-source and live on the Helder devnet.

Optimism Adopts ERC-7683

Across, a cross-chain bridge protocol, announced that Optimism is adopting ERC-7683, a cross-chain intents standard that allows order fillers from any compatible system to fulfill intents by adhering to a unified order structure. Optimism will implement the intents standard on top of its new native interoperability architecture. By adopting ERC-7683, Optimism is extending its native interoperability to reach the broader Ethereum ecosystem. The two systems help enhance the speed, security, and cost-efficiency of cross-chain transfers for users. ERC-7683 was developed by Across in collaboration with Uniswap Labs.

Status Announces L2 On Linea

Private messaging platform Status announced plans to launch the Status Network, a new layer-2 rollup built on the Linea software stack. Status will also join as the first contributor to Linea's tech stack. Linea is an EVM-equivalent ZK-rollup by Consensys.
