Description
Chainway Labs is a blockchain infrastructure company that researches, builds, deploys, and scales technology at the intersection of Bitcoin, Ethereum, and zero-knowledge cryptography. Its flagship product is Citrea, described as Bitcoin's first ZK rollup, which enhances Bitcoin blockspace with zero-knowledge technology to enable smart contract functionality directly secured by Bitcoin. Previously, Chainway Labs built Proof of Innocence, a protocol allowing Tornado Cash users to prove via zero-knowledge proofs that their withdrawals are not linked to illicit funds (adopted by projects such as Railgun DAO and covered by outlets including CoinDesk, Bloomberg, The Block, and CryptoSlate), as well as OrdinalSafe, a now-discontinued browser extension for non-custodial storage and transfer of BTC and Inscriptions. The company's work targets crypto-native builders and users within the Bitcoin and Ethereum ecosystems.
