According to PANews, Ethereum Layer2 network Scroll has announced the launch of its highly anticipated Darwin upgrade, scheduled for August 21, 2024. The upgrade aims to reduce gas fees by 34% through a single aggregated proof, thereby lowering the costs associated with multiple batches. By bundling multiple batch proofs into a single validity proof, the Darwin upgrade will decrease verification costs. This improvement will be achieved by introducing a new batch encoding format and bundling concept.

The specific timeline for the upgrade includes deployment on the Scroll Sepolia testnet on August 14 and the execution of the contract upgrade on the Scroll mainnet on August 21. The security of this upgrade has been audited by Trail of Bits.
