Interledger.js Ledger Plugin for Bitcoin using CLTV Payment Channels

This plugin enables Interledger payments through Bitcoin using simple payment channels.

ilp-plugin-bitcoin-paychan implements the Interledger.js Ledger Plugin Interface, which allows Bitcoin to be used with ilp client and the ilp-connector.

Dependencies:

• Node.js >=v7.10.0
• Bitcoin Cored Node

Setup:

git clone https://github.com/interledgerjs/ilp-plugin-bitcoin-paychan.git
cd ilp-plugin-bitcoin-paychan
npm install

ilp-plugin-bitcoin-paychan uses simple unidirectional Bitcoin payment channels implemented with CHECKLOCKTIMEVERIFY (CLTV). While the underlying channel is not conditional (i.e. does not use hashlocks), the plugin only sends updates to the channel when it receives the fulfillment from the other party. This means that payments that there is some risk for payments that are in flight. However, the Interledger Protocol isolates participants from risk from indirect peers.

By implementing all of the functions required by the Ledger Plugin Interface, this allows Bitcoin to be used by standard Interledger.js components.
