Odaily News Cardano will unlock over $1.3 trillion in Bitcoin liquidity for its DeFi ecosystem through a new integration with Bitcoin smart contract platform BitcoinOS (BOS). The purpose of this integration is to enable Cardano users to securely access Bitcoin without intermediaries, thereby driving improvements in cross-chain functionality and the expansion of DeFi. ZK cryptography will play a key role in this collaboration, providing a trustless method for BOS to integrate BTC assets onto Cardano through verified transactions that do not involve third parties. The BOS Grail bridge is a key integration component that provides a trustless connection powered by BOS's ZK BitSNARK verification protocol. (Cointelegraph)
