Building Secure and Watchtower-efficient Bitcoin Payment Channels with BitVMX
This article presents a sample payment channel that uses to support efficient revocations. It can be easily extended to function as a state channel and support Hash-Time Locked Contracts (HTLCs) for lightning-like routing. However, we aim to keep it simple so that it serves as a clear example of BitVMX’s capabilities and how it can be integrated as a subcomponent of other Bitcoin protocols.
