Byzantine Swaps -- A Rigorously Secure Way For Cross-Chain Asset Exchange
Channel: Hyperledger Foundation
Date: 28/02/2023

A virtual meetup hosted by Hyperledger San Francisco on February 28, 2023 with Francis Mendoza speaking about Byzantine Swaps and blockchain interoperability.

Blockchain interoperability has the potential to unlock magnitudes more value from the disparate and siloed layer-one ecosystems, functionally doing for the industry what the Hypertext Transmission Protocol (HTTP) did for the fledgling internet.

The prior art for cross-chain transactions primarily involved utilization of bridges as the most popular choice, with atomic cross-chain swaps following suit. However, the fundamental security limits of bridges and the string of recent exploits block mass-adoption.

In this talk, we propose "Byzantine Swaps": a novel iteration of trustless cross-chain atomic swaps with greater security guarantees as an alternative to classical bridges and to advance security-centric interoperability developments in Blockchain R&D. We also perform a live demonstration of the cross-chain transfer of Nonfungible and Fungible assets across a Fabric-to-Fabric Network atop Hyperledger Weaver.
