Optimism Highlights 🔴✨

Optimism Announces OP Airdrop 3
Optimism announced its third airdrop, distributing 19 million OP tokens to over 31,000 unique addresses. The airdrop rewarded users based on the OP tokens they had delegated, with a minimum threshold. The calculation multiplies the amount of delegated OP tokens by the number of days they are held. The minimum threshold is equivalent to delegating 180 OP over 100 days. Participants who delegated to an active delegate who voted in at least one onchain proposal received a 2x multiplier. The maximum reward per address was capped at 10,000 OP tokens. This eligibility period extended over six months, running from January 20th to July 20th. Approximately 570 million OP tokens remain available for future airdrops.

Canto Migrates To ZK Chain On Polygon CDK

Canto, a Layer-1 EVM blockchain focused on DeFi, is migrating to a ZK-powered chain built on Polygon’s Chain Development Kit (CDK). Canto’s new ZK-powered L2 will focus on real-world assets. The transition provides Canto with cryptographic security through the adoption of a Plonky2 ZK proving implementation. Canto will also have access to deep liquidity through a shared ZK bridge on Polygon 2.0. Canto developers can leverage the ZK bridge for canonical assets, enhanced decentralization, and trustless asset bridging. Canto aims to further neofinance, a concept for enhancing capital efficiency by deploying offchain assets with protocol rails.

Aztec Network Announces Fernet

Aztec Network announced the winning proposal from its Sequencer Selection Request for Proposals. The winner, Fernet, is a sequencer selection protocol distinguished by its permissionless random leader election, enabling anyone to participate in block building on the Aztec Network. Random leader election promotes inclusivity, decentralization, and resistance to censorship. The decision to choose Fernet over other proposals was based on its straightforwardness, security, and simple implementation. Systems engineering firm BlockScience also provided an independent report on the sequencer selection protocol. Fernet employs VRF to assign random scores to sequences.

Geth v1.13.1 Hotfix Release

Go Ethereum released Geth v1.13.1, a hotfix release addressing a bug relating to block production in v1.13. The release also addresses active fork detection issues, database corruption during snap sync, and RPC API gas price calculation. It also introduces support for configuring Geth via environmental variables.
