LedgerLoops

Examples:

• in-browser: shows a graph of friends, you can tell friends to give each other money, and they will cooperate to find and resolve ledger loops. See the README in that folder for instructions.

• client-server: example where Marsellus lives server-side, while Mia and Vincent live client-side. Shows and tests how WebSockets are used. See the README in that folder for instructions.

• monetized-blog: static page, combined with a WebSocket server, that will accrue money when a user with the LedgerLoops browser extension visits this page. This demo is still under construction. See https://github.com/ledgerloops/ledgerloops/issues/21.

• monetized-blog-heroku: Same as the previous demo, but running on Heroku instead of on localhost, and with the statics server rolled into the LedgerLoops agent server.

• API

• LedgerLoops.Agent constructor (myName, mySecret, credsHandler)

  • myName and mySecret are used when connecting to a server
  • credsHandler ({ peerName, peerSecret}) => Boolean is called when someone else connects as a client

• Agent#addClient: function(options) { return this.hubbie.addClient(Object.assign({ myName: this._myName, mySecret: this._mySecret, protocols: [ LEDGERLOOPS_PROTOCOL_VERSION ] }, options)); }

• Agent#listen: function (options) { return this.hubbie.listen(Object.assign({ protocolName: LEDGERLOOPS_PROTOCOL_VERSION }, options)); }

• Agent#addTransaction: function (peerName, amount) return this._propose(peerName, amount); }

• Agent#getBalance ()

  • returns a hash with the bank's current, payable, receivable balances.

* Agent#payIntoNetwork(peerName, value)

* instruct the Loops engine to use your balance from the account with that peer to pay into the network

* Agent#receiveFromNetwork(peerName, value)

* instruct the Loops engine to use the account with that peer to receive balance from the network
