Circle Taps Malachite in Building Arc, a Blockchain Focused on Stablecoin Finance

Circle has acquired Malachite, the high-performance consensus engine developed by Informal Systems, to power its upcoming Arc1 blockchain, a Layer-1 network built for stablecoin finance.
Arc, set to launch testnet later this year, will leverage Malachite’s Byzantine Fault Tolerant consensus based on Tendermint to deliver secure and reliable stablecoin transactions. While several Informal team members will join Circle to support Arc’s development, Malachite will remain open source, ensuring continued industry access and innovation as Informal advances its broader blockchain projects.
