FLEX: Capital-Efficient Fraud-Proofs for Bitcoin Bridges

As Bitcoin interoperability advances, a persistent challenge remains: building secure, scalable bridges without locking up vast amounts of idle capital. FLEX (Fraud proofs with Lightweight Escrows for eXits) introduces a breakthrough approach to this problem. 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.

WISCH, An efficient data signing scheme via correlated signatures

As disputable computing protocols for Bitcoin evolve, data signing fees remain a significant portion of total operational costs. We’ll explore how WISCH, a new data signing scheme for Bitcoin, can help cut costs and optimize the efficiency of BitVMX, BitVM2, and Garbled Circuits solutions.

Building Advanced Bitcoin Protocols with BitVMX

This talk examines the building blocks that BitVMX provides for constructing complex disputable computing systems on Bitcoin. We will analyze the architectural design of these components, and discuss advanced solutions that emerge from their composition. The presentation will also reflect on lessons learned during the development of applications that use these techniques.
