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)O(1) storage per channel, minimal information leakage, and compatibility with Lightning Network routing.
