  • Enhanced bridge features include dispute resolution, on-chain verification, and integration with BOB Gateway

BOB ("Build on Bitcoin"), is a hybrid Layer-2 blockchain that combines Bitcoin's security with Ethereum's DeFi capabilities, it has officially launched its trust-minimized BitVM Bitcoin bridge on public testnet in collaboration with Fiamma.

This development represents a significant milestone in BOB's mission to provide secure, trust-minimized access to Bitcoin DeFi.

Unlike wrapped Bitcoin variants such as wBTC and cbBTC, Bitcoin bridged via BitVM is non-custodial and trust-minimized, ensuring funds remain secure if there is a single honest, online node.

"Removing the need for third-party bridges to deploy Bitcoin across DeFi is a major step toward unlocking Bitcoin's trillion-dollar potential," said Alexei Zamyatin, BOB Co-Founder and BitVM Core Contributor. "We've gone from concept to BitVM2 design, to prototype and now to public testnet in just a year."

Key improvements to the bridge include a dispute resolution mechanism with on-chain challenge functionality, verification of correct payments through an on-chain relay, and integration with BOB Gateway for efficient deposits and withdrawals.

Alongside the bridge launch, BOB has established the BitVM/acc Implementation Working Group to accelerate BitVM's adoption.

This initiative brings together industry leaders to refine BitVM's functionality and ensure its practical integration across the Bitcoin DeFi ecosystem.

Founding members include institutional partners like Amber, Anchorage, Rockaway, and Wintermute, and research partners including Babylon, Fiamma, and ZeroSync.

BOB's hybrid Layer-2 model aims to merge Bitcoin's security and capital with Ethereum's DeFi innovation, positioning BTC as the backbone of a new decentralized finance system without relying on third-party bridges for interoperability.
