According to Blast Scan, blocks stopped publishing around 10 am ET.

The “[layer-2] with native yield” drew criticism for initially soliciting deposits to a multisig wallet. All told, it saw $2.3 billion in deposits before its layer-2 went live. The layer-2, which went to mainnet in late February, is a fork of Optimism. As of Wednesday morning, Blast had surpassed Optimism as the second-largest Ethereum rollup by total value locked (TVL), according to DeFiLlama. The 51 protocols built on Blast cumulatively held over $1 billion. 

Optimism itself continued producing blocks through the Dencun upgrade. 

Blast said over 3,000 projects entered its developer contest to go live upon the layer-2’s mainnet launch and receive a larger airdrop allocation. Developers on Blast told Blockworks they were drawn to the rollup’s deep liquidity and its founder’s previous success building the NFT marketplace Blur.

EIP-8363 would progressively burn validator rewards as the staking ratio rises, reaching a 0% staking yield above a 50% staking ratio, limiting issuance-driven stake growth while preserving incentives for validators to perform their duties. Supporters argue that lower issuance would reduce unnecessary dilution, strengthen ETH’s monetary premium and maintain a large unstaked constituency capable of resisting validator capture. Critics contend that the modest inflation reduction may not justify the risks to staking products, institutional demand and the LST-based DeFi economy. Its equilibrium and prospects for adoption remain highly uncertain.
