Linea's mainnet points system upgrade introduces a multi-chain gas consumption mode, integrating chains like Arbitrum and zkSync to boost activity weight verification. The upgrade enhances gas efficiency, reducing fees by up to 66% while maintaining EVM compatibility. Users earn points based on gas usage across supported chains, with increased weights for higher activity. Sybil detection is strengthened via clustering algorithms and multi-chain interaction verification. This incentivizes genuine engagement, rewarding active participants while filtering out manipulative behaviors. The system aligns with Linea's goal of seamless Ethereum Layer-2 scaling, offering developers mainnet-like functionality with optimized performance. By leveraging Arbitrum’s Optimistic Rollups and zkSync’s ZK proofs, the upgrade ensures robust verification and scalability, fostering a more active and secure ecosystem.
