A module for bitcore that implements Payment Code

Getting Started

This library is distributed in both the npm and bower packaging systems.

npm install bitcore-payment-code
bower install bitcore-payment-code

// Generating a Payment code and its notification address for Alice

var PaymentCode = require('bitcore-payment-code');

// Alice's extended private key: MasterPrivKey

var xPrivKey = MasterPrivKey.derive("m/47'/0'/0'"); // See BIP47 for details
var xPubKey = xPrivKey.hdPublicKey;


var alicePc = new PaymentCode([xPubKey]); // Generate a payment Code
//also, new PaymentCode([xPubKey0, ..., xPubKeyN], m)  // Multisig M-N

var serializedPaymentCode = alicePc.toString(); // PaymentCode to share

var aliceNotificationPubKey = alicePc.publicKey;  
var aliceNotificationAddress = aliceNotificationPubKey.toAddress();


// Making a payment to Bob
var paymentInfo = alice.makePaymentInfo(BobPaymentCode, xPrivKey, index, outpoint);

// Index is the alice->bob payment order
// outpoint is where in the transaction the public key will be exposed

// Sample output:
 { 
  publicKeys: [ '023ded791973898f6892cead1b62ba57b9e5dc6c45aeaf0f20813acec96540cec1' ],
  paymentAddress: '1AJ3gNTaJ96NBDcj4cVmPZVBB7sF9rVA31',
  notificationOutputs: [ '010003874d18c82ce5fa774d3cefa16129159cc893007015e5791c0e1d1edba8d4fec48654656a77d16a1c25aaf61423c56973f71d526aab8a10fcc6cb65f3f21c403d00000000000000000000000000' ],
  notificationAddresses: [ '14L2fpcYwQQMmJvVJeewyuvdGfi49HmCZY' ] }
  }

// Then alice needs to send a notification TX:
// .from should be a valid UTXO



// Then the TX should be broadcasted... And the actual payment sent to `paymentInfo.paymentAddress`
// For future payments, index should be incremented.


// ===================================================
// Bob retrieval of the payment....


// When Bob receives a TX on his notification address:
