SP1, a general-purpose zkVM by Succinct Labs, is now production-ready. SP1 facilitates the development of zero-knowledge proofs using Rust, enhancing code maintainability, auditability, and adaptability. According to Succinct Labs, SP1 can process proofs up to 10 times faster and cheaper than competing zkVMs. SP1 has secured over $1 billion in TVL and processed over 10,000 proofs. It is used by Polygon to generate pessimistic proofs on the AggLayer and is built on Polygon’s Plonky3 proving system. Verifying an SP1 proof on Ethereum requires only 275k gas. SP1’s code is open-source and available for developers to use.
Erigon introduced OtterSync as part of its Erigon 3 alpha 2 release. OtterSync is a new synchronization algorithm that speeds up the setup of both full and archive Ethereum nodes. OtterSync shifts the initial synchronization load from the CPU to network bandwidth. The efficiency is achieved by downloading state data through secondary protocols like BitTorrent instead of direct execution. OtterSync enhances data distribution and verification processes, reducing the frequency of required software updates while improving data availability and maintaining the integrity of the network. The alpha 2 release also brings improvements to chain tip performance, disk usage, and block importing times. Erigon 3 is an all-in-one EVM node that supports both execution and consensus layers.
Optimism introduced a new fault-proof program named Kona and a virtual machine called Asterisc as part of its multi-proof system. Kona enhances the verification processes and secures reliable state transitions throughout the growing network of OP Stack chains. The Asterisc VM is designed to authenticate the execution of RISC-V programs using interactive fraud-proofs. The multi-proof system follows the principle of client diversity in Ethereum, by adding redundancy to enhance fault tolerance and remove single points of failure. Optimism initially enabled fault proofs on mainnet in June, advancing it to a stage 1 rollup. Kona and Asterisc are currently in a development phase and are not yet production-ready.
