According to Cointelegraph, Cardano is poised to unlock over $1.3 trillion in Bitcoin liquidity for its decentralized finance (DeFi) ecosystem through a new integration with BitcoinOS (BOS), a Bitcoin smart contract platform. This integration aims to enable Cardano users to securely access Bitcoin (BTC) without intermediaries, enhancing cross-chain functionality and expanding DeFi capabilities.

Zero-knowledge (ZK) cryptography will be instrumental in this collaboration, providing a trustless method for integrating BTC assets into Cardano through verified transactions that bypass third parties. The BOS Grail bridge, a crucial component of this integration, will offer a trustless connection powered by BOS’ ZK BitSNARK verification protocol. This technology allows BTC transactions and assets to be bridged onto Cardano’s blockchain, benefiting Cardano-native DeFi projects without compromising decentralization or security. With this integration, Bitcoin’s market capitalization of approximately $1.3 trillion will become accessible to the Cardano ecosystem.

Emurgo, the founding entity behind Cardano’s Web3 adoption efforts, views this collaboration as a significant step toward a more interconnected space. Ken Kodama, CEO of Emurgo, stated that the integration has the potential to unlock new cross-chain capabilities and drive DeFi adoption. Kodama emphasized that BOS’ bridge and ZK technology could further strengthen Cardano by providing its users, projects, and developers with a secure and trustless path to BTC.

On September 10, BOS partnered with the layer-2 (L2) scaling solution Merlin Chain to deploy the BitcoinOS Grail bridge, enhancing cross-chain transactions without centralized trust mechanisms. Jeff Yin, founder of Merlin Chain, highlighted that the partnership would offer users a trustless, decentralized bridge for Bitcoin-native assets. The bridge establishes ZK-proof-powered trustless bridging directly onto the BTC blockchain, eliminating the need for centralized security measures such as multisig or multiparty computation. Yin described this development as just the beginning, as the collaboration aims to create a more interoperable Bitcoin ecosystem.
