Arbitrum BoLD Goes Live On Mainnet
Arbitrum Bounded Liquidity Delay (BOLD), a dispute resolution protocol featuring interactive fraud proofs, is now live on mainnet. BOLD allows anyone to run a validator node, enabling permissionless validation. BOLD protects against delay attacks by implementing a fixed upper limit of 7 days for resolving disputes. Delay attacks occur when malicious actors spend funds to delay the confirmation of transactions. With BOLD, honest validators can collaborate and pool resources to successfully win disputes, even when facing multiple malicious actors. Arbitrum Orbit chains will be able to adopt BOLD by updating their Arbitrum Nitro stack.
Lens Chain, a SocialFi L2 built on ZKsync’s ZK Stack, announced plans to adopt Aave’s GHO stablecoin as its gas token. The implementation follows the GHO Gas Token Framework developed by Aave Labs, aiming to enhance user onboarding and minimize friction. Transaction fees will be dynamically priced in GHO, adjusting to the Ethereum gas market. GHO’s integration with the ZKSync Shared Bridge serves as the primary liquidity bridge and will enable seamless GHO minting on Lens Chain. Lens Chain will roll out in three phases, evolving from a Validium to a Volition. The network will process financial transactions in ZK Rollup mode while handling social transactions in Validium mode.
Paradigm released Reth v1.2, the latest version of its Ethereum execution client written in Rust. The release includes a new default gas limit of 36 million, a parallelized state root computation system, and Pectra hardfork readiness for Holesky and Sepolia testnets. The update delivers a 50% improvement in engine_newPayload call latencies and enhances state root computation efficiency. The release maintains Reth’s goal of combining Erigon’s compact archive node architecture with high-performance execution while moving towards further optimizations. Reth aims to improve Ethereum node stability, with optimizations in sync time, storage, and RPC throughput. Future releases will expand support to OP Stack L2s.
CBOE submitted Form 19b-4 to the SEC, seeking approval to enable staking in the 21Shares Core Ethereum ETF. Bloomberg analyst James Seyffart noted that it marks the first ETF filing to request staking. Once approved, the SEC would still need to greenlight the required Form S-1 filings before trading can commence. Following the news, ETH surged 2.5% to $2,750.
