Fairgate Introduces FLEX: Capital-Efficient Fraud Proofs for Bitcoin

Fairgate introduces FLEX, a new fraud-proof system for Bitcoin bridges that eliminates the need for large, permanent security bonds. Built using garbled circuits and compatible with the BitVM and BitVMX ecosystems, FLEX enables on-demand security bonds that are only activated when a dispute arises. This reduces costs without compromising security.

πŸ”— Introducing FLEX: Capital-Efficient Fraud-Proofs for Bitcoin Bridges

Built using garbled circuits and compatible with the BitVM and ecosystems, FLEX enables on-demand security bonds that are only activated when a dispute arises. This reduces costs without compromising security.
The result is a bridge architecture that is more capital-efficient, decentralized, and resilient to denial-of-service attacks, while maintaining compatibility with Bitcoin’s existing consensus rules: no soft-forks or opcode changes required.
