Implement a Payment Channel with Libp2p
summary
Shows a working proof‑of‑concept: a Solidity channel manager contract plus JavaScript libp2p nodes that exchange signed state updates and settle on chain. Uses an ERC‑20 escrow, OpenZeppelin ECDSA signature recovery to verify counterparty messages, nonce + timeout dispute logic, and a ganache local chain for testing. Claims thousands (e.g. 10,000) of free off‑chain updates, but code is explicitly not production‑ready and contains known bugs; demo partially works over libp2p and ganache local chain.
