This is an example repository to help in the implementation of an unidirectional payment channel.
The script will start a dogecoind regtest node inside a docker container. Initiate a payment channel using a p2sh multisig. Sign 2 payments. Close the payment channel by broadcasting the final transaction.
$ npm install
$ npm start
index.old.js was a first draft.
first step is basically GET pubkey then 2nd step is response so after this alice needs to tell bob "hey i funded a p2sh with amount x" i think this can be a psbt https://github.com/rllola/doge-payment-channel/blob/a70dae06a84ed036fc1f3cbab7836a8d41eae457/index.old.js#L52-L65 so you'd accept that on your endpoint (you anyway need to accept these) and if there are no outputs, then it means its the announcement of a new channel https://github.com/rllola/doge-payment-channel/blob/a70dae06a84ed036fc1f3cbab7836a8d41eae457/index.js#L166-L173 this one in the index.js need a little envelope around the psbt I think so for example: POST /payment { "type": "announce", "ref": undefined, "psbt": "hexstring" } then you code a controller that:
- parses the json
- based on the type, routes to a service:
- "announce" => PCAnnounceService or something
- implement PCAnnounceService to take the message object and
- decode pbst after that we implement some checks and then we store that shit lmk if thats doable
