Babylon Labs, developer of the biggest BTC staking protocol, is constructing a trust-minimized Bitcoin bridge with the Cosmos community to reinforce the world’s oldest blockchain’s interoperability.
In partnership with Bitcoin builders Fiamma, Babylon is utilizing the BitVM2 computing paradigm, which is designed to permit Ethereum-style sensible contracts on Bitcoin, which then paves the way in which for zero-knowledge expertise.
Zero-knowledge computations permit completely different events to confirm that data is correct with out really revealing to one another what the knowledge is. On this sense, it’s foundational to bridging digital property between completely different blockchains.
Builders like Babylon Labs and Fiamma are aiming to unlock the deep wells of worth saved in BTC to finance different ecosystems and permit it to be transacted on blockchains which might be freed from a few of Bitcoin’s limitations of velocity and scale.
This kinds a part of a broader motion to extract larger utility from Bitcoin, just like that which is commonplace on networks like Ethereum. Babylon’s Bitcoin staking protocol, which is likely one of the foremost tasks on this sector, is billed as a manner of utilizing BTC to safe different protocols and decentralized functions and has a complete worth locked (TVL) of round $5.5 billion.
The introduction of BitVM2’s predecessor by Robin Linus in October 2023 was hailed as a breakthrough for making Bitcoin extra programmable, via enabling a rollup that may deal with sooner and cheaper transactions with out compromising safety. This might then permit bridges to securely switch BTC to the rollup, and later deliver the BTC again in order that deposits may be withdrawn.
BitVM impressed loads of fervor amongst builders constructing tasks on Bitcoin, together with some centered on bridging to different networks. Zero-knowledge rollup Citrea, which is backed by Galaxy Digital, deployed a BitVM-based bridge to the Bitcoin testnet final September. It’s designed to be appropriate with the Ethereum Digital Machine (EVM), the smart-contracts-executing software program that powers the Ethereum protocol.
