Midnight is a privacy-focused Cardano sidechain, with developer Sebastien Guillemot outlining its potential role as a cross-chain bridge between Ethereum and Cardano. Guillemot stated that the network has completed a critical cryptographic step by integrating Ethereum's Keccak hash function and Cardano's Blake2b hash function, enabling cross-chain wallet verification without compromising user privacy. He emphasized that users can retain their existing wallets while engaging in private interactions. As interest in privacy protocols grows, this advancement expands Midnight's vision and solidifies its recent token airdrop and partnerships.
