On October 24, Cardano unlocked more than $1.3 trillion in bitcoin liquidity for its DeFi ecosystem through a new integration with BitcoinOS (BOS), a bitcoin smart contract platform. The integration is designed to improve cross-chain functionality and DeFi scaling by giving Cardano users secure access to Bitcoin without an intermediary.ZK cryptography will play a key role in this partnership, providing a trust-less method by which BOS can integrate BTC assets onto Cardano through verified, third-party-neutral transactions.
