Hedgehog is a protocol enhancing Bitcoin's layer two payments, offering simpler, two-party payment channels akin to Lightning but with some advantages:

-It simplifies state updates, allowing one party to propose changes and the other to accept at their convenience (kinda like ecash protocols without a central server.)

-Payments can be made asynchronously (improving usability and flexibility in transactions).

on GitHub: supertestnet/hedgehog.

this doesn't fix lightning lol
