Babylon Labs, the developer of the largest BTC staking protocol, is constructing a trust-minimized bridge with the Cosmos network to enhance interoperability with Bitcoin 
$64,158, the oldest blockchain in the world. This initiative aims to introduce new functionalities to the Bitcoin ecosystem.
BitVM2 Technology Enables Ethereum-Like Smart Contracts
In collaboration with developer Fiamma, Babylon is utilizing the BitVM2 computing paradigm to enable Ethereum 
$1,819-style smart contracts on Bitcoin. This technology paves the way for zero-knowledge proofs, allowing for the bridging of digital assets between different blockchains.
Zero-knowledge computations enable parties to verify information without revealing it to each other. This forms the foundation for the secure transfer of digital assets across different blockchains. Developers like Babylon Labs and Fiamma aim to leverage this technology to finance other ecosystems and facilitate transactions on blockchains free from Bitcoin’s speed and scaling limitations.
The Future of BitVM2 and Programmability
Introduced by Robin Linus in October 2023, BitVM2 is viewed as a turning point for making Bitcoin more programmable. BitVM2 offers a rollup capable of handling faster and cheaper transactions without compromising security. This allows for the secure transfer of BTC to the rollup and its subsequent retrieval.
BitVM2 has sparked significant interest among developers working on projects atop Bitcoin. A zero-knowledge rollup named Citrea, backed by Galaxy Digital, deployed a BitVM-based bridge to the Bitcoin testnet in September, designed to be compatible with the Ethereum Virtual Machine (EVM).
Babylon’s Bitcoin staking protocol aims to secure BTC for other protocols and decentralized applications, boasting a total value locked of approximately $5.5 billion. These advancements are part of a movement to derive more utility from Bitcoin and bring functionalities prevalent in networks like Ethereum to Bitcoin, preparing it for a more active role in the DeFi ecosystem.
Meanwhile, institutions like Lombard Finance have expressed views that Bitcoin could become the preferred collateral in DeFi. The new bridge between Bitcoin and Cosmos may enhance blockchain interoperability, allowing digital assets to be utilized in a broader ecosystem, contributing to Bitcoin’s flexibility and functionality while creating new opportunities for users.
