Solana's biggest consensus overhaul, Alpenglow, is now live on a community test cluster, moving the network from its current Proof-of-Stake, TowerBFT, and Proof-of-History system toward a new architecture aimed at reducing finality times and improving responsiveness. This marks a major step toward potential mainnet rollout. Meanwhile, LayerZero admitted it made a mistake by allowing its verification infrastructure to act as a single verifier for high-value transactions, a vulnerability exploited in the $292 million Kelp DAO hack initially blamed on the developer. Ronin is officially transitioning from a sidechain to an Ethereum layer 2 on May 12, executing a hard fork that will cause about 10 hours of downtime, aiming to improve security after its 2022 bridge exploit. Additionally, the Ethereum Foundation and wallet developers released a new 'Clear Signing' standard to help users understand transaction details before signing, addressing blind signing exploited in attacks like the Bybit hack.
