OTS-PC: OTS-based Payment Channels for the Lightning Network (2511.04021v1)
Published 6 Nov 2025 in cs.CR and cs.NI
Abstract: We present a new type of bidirectional payment channel based on One-Time Signatures on state sequence numbers. This new construction is simpler than the Poon-Dryja construction, but provides a number of benefits such as $O(1)$ storage per channel, minimal information leakage, and compatibility with Lightning Network routing.
