Arbitrum Unveils Integration with BitcoinOS (BOS), Transforming Its Layer-2 Network into a Hybrid Rollup

This collaboration marks a groundbreaking shift, offering a robust and interoperable scalability solution between the two ecosystems.

Layer-2 network Arbitrum has announced a major integration with BitcoinOS (BOS), transforming Arbitrum into a hybrid rollup that combines the strengths of Ethereum and Bitcoin.

This collaboration marks a significant development, offering a robust and interoperable scalability solution between the two ecosystems.

With this innovation, Arbitrum users will now be able to tap into the $2 trillion liquidity of Bitcoin in a trustless manner, enabling seamless exchange and transfer of assets between Bitcoin and Ethereum with near-instant finality.

Moreover, the integration opens up new possibilities for developers, who can now create DeFi products on Bitcoin, overcoming current limitations.

Delving into the integration with BitcoinOS and the benefits of the Grail Bridge

BitcoinOS introduces BitSNARK, an innovative technology that enables trustless bridging of BTC through BOS Grail, a non-custodial transfer system that drastically reduces counterparty risk compared to existing solutions.

With this integration, Arbitrum One will harness the security of Bitcoin, ensuring scalability, liquidity, and interoperability between the two networks. Currently, Arbitrum boasts the highest TVL among all layer-2s, exceeding $16 billion, and this integration will further contribute to solidifying its leadership in the industry.

“The integration of BitcoinOS with Arbitrm showcases how our technology can empower the expansion of the Bitcoin ecosystem,” stated Nina Rong, Head of Partnerships at Arbitrm Foundation. “This collaboration demonstrates our commitment to enabling trustless bridging and programmability for Bitcoin, without compromising the security of the network.”

As Edan Yago, main contributor of BitcoinOS, puts it, “BOS has unlocked the ZK technology needed for Bitcoin to speak to other ecosystems, allowing any chain to now build and innovate on top of Bitcoin, the most secure network.” This pivotal change eliminates the competition and fragmentation between Ethereum and Bitcoin, forging a unified and complementary solution.

Ultimately, thanks to Arbitrm and BOS, users will be able to leverage the benefits of Ethereum L2 without being limited by Bitcoin's native scaling solutions. This translates to greater efficiency, security, and a scalable infrastructure for DeFi applications and dApps.

Security, speed, and guaranteed purpose

One of the key challenges for Bitcoin has been the lack of smart contract functionality, which has isolated its vast $2 trillion liquidity from Ethereum's DeFi applications. The integration with Arbitrm and BOS marks a groundbreaking development: using the Grail system, users will be able to access the entire Bitcoin ecosystem in a trustless manner, without the centralization risks posed by solutions such as Wrapped Bitcoin (WBTC), which currently holds over 129,000 BTC on the Ethereum network.

Furthermore, thanks to BOS Grail Vaults, withdrawals from Arbitrm to Bitcoin will occur without the 7-day waiting periods that characterize many optimistic rollups, ensuring fast and secure transactions with immediate finality.

The integration of Arbitrm with BitcoinOS marks a new era for decentralized finance on Bitcoin. With enhanced scalability, security, and interoperability between the two largest blockchain ecosystems, users and developers will gain access to a broader market, presenting unparalleled opportunities for innovation.
