Union Bridge: A Trust-Minimized Bitcoin Bridge
Cross-chain interoperability is a critical challenge in the blockchain ecosystem, especially when it comes to bridging Bitcoin with other networks. Existing solutions often rely on centralized intermediaries, exposing users to counterparty risks and censorship concerns. At Fairgate, in collaboration with Rootstock Labs, we set out to tackle this issue by developing the Union Bridge —a trust-minimized bridge, based on BitVMX, between Bitcoin and Rootstock.
