PANews reported on April 23 that according to The Block, Ethereum Layer 2 network Scroll is promoting a major protocol upgrade called "Euclid", which is expected to reduce transaction fees by 90% and increase network throughput. The upgrade includes five core improvements: migration to a new L2 prover, adoption of the MPT state commitment system (natively compatible with Ethereum), optimization of the Rollup process, support for the EIP-7702 account abstraction proposal, and compatibility with the RIP-7212 Rollup improvement standard.

The technical team said that the Euclid upgrade will abandon Scroll's current "halo2 circuit" - the zero-knowledge proof circuit used to verify transactions, which is designed to replicate the Ethereum virtual machine of Scroll's zkEVM (zero-knowledge Ethereum virtual machine). In particular, the team will migrate the network to a new OpenVM, which provides more auditable and cheaper prover code and "supports arbitrarily complex transactions." Euclid will also introduce "MPT state commitments," the Merkle-Patricia Trie proofs used natively by Ethereum, which in theory will make it easier to build decentralized applications and improve the performance of the sorter.
