Ethereum's Altair upgrade is progressing as planned with Pyrmont testnet successfully upgraded and scenario testing currently underway. The Prater testnet upgrade is scheduled for September 2 at 12pm UTC, with mainnet deployment to follow after successful testing completion.
Ethereum's London upgrade is ready for deployment with merge checklist and draft EIP finalized. Altair devnets have launched as clients prepare for mainnet implementation of consensus layer improvements.
The Ethereum Foundation disclosed the first set of vulnerabilities from its Bug Bounty Programs for both Execution and Consensus layers. These security issues were previously discovered and reported through the foundation's official bounty programs, representing a transparent approach to vulnerability management.
Ethereum currently supports two types of clients following the beacon chain launch in 2020: execution-layer clients (eth1) and consensus-layer clients (eth2) for proof-of-stake. Validators must run both client types as they serve different but complementary functions in the network.
The article announces allocation updates for Q3 and Q4 2021 grantees, featuring updated terminology where Ethereum 1.0/1.x is now called 'Execution Layer' and Ethereum 2.0 is now 'Consensus Layer'. This represents part of a broader effort to standardize Ethereum development terminology.
