Namecoin Support Module for Bitcore

bitcore-namecoin adds namecoin support to bitcore for creating namecoin name_* transactions, private keys, and scripts in Node.js and web browsers.

Note: This is still experimental software. This module is not intended for use in production environments, or for use where real money is at stake, at this point.

See the main bitcore repo for more information.

Getting Started

npm install bitcore-namecoin

bower install bitcore-namecoin

To import a namecoin WIF (from vanitygen, for example):

// return bitcore with namecoin commands overlayed
var bitcore = require('bitcore-namecoin');
var privateKey = bitcore.PrivateKey.fromWIF('74pxNKNpByQ2kMow4d9kF6Z77BYeKztQNLq3dSyU4ES1K5KLNiz');
var address = privateKey.toAddress();
console.log( address.toString());
// NAMEuWT2icj3ef8HWJwetZyZbXaZUJ5hFT

To create a name_new transaction:

var bitcore = require('bitcore-namecoin');
var tx = new bitcore.Transaction()
  .from(utxo)
  .nameNew('d/name', 'randomvalue', 'mzGfeiJFdQyiuQnhB45aeBYefzHJSsiSfj')
  .change('mpe83RGRVWibHrdgfmkJwTxgufNs9quaZC')
  .fee(0.005)
  .sign(privKeySet); // utxo and nameNew output addrs need to have privKeys here
// now we can broadcast out to the network
var serialized = tx.serialize();

To create a name_firstupdate transaction:

var tx = new bitcore.Transaction()
  .from([utxo, nameNewUtxo])
  .nameFirstUpdate('d/name', '092abbca8a938103abcc', 'VALUE', 'mzGfeiJFdQyiuQnhB45aeBYefzHJSsiSfj')
  .change('mpe83RGRVWibHrdgfmkJwTxgufNs9quaZC')
  .fee(constants.NETWORK_FEE.satoshis)
  .sign([privKeys[inputAddr], privKeys[nameNewAddr]]);
var serialized = tx.serialize();

To create a name_update transaction:

var tx =  new bitcore.Transaction()
  .from(utxos)
  .nameUpdate('AAAAAAAAAA', 'CCCCCCCCCC', 'mkGdewyuvU13uHzpMUZe2t8ii4LKgKC8mE')
  .change('mkVNqbVqcYxi3zB2fRfiRQonf4JjwdAvnE')
  .fee(constants.NETWORK_FEE.satoshis)
  .sign([privKeys[outputAddr],privKeys[nameFirstUpdate]]);
var serialized = tx.serialize();

Details

bitcore-namecoin works by pulling in bitcore and then adding Namecoin-specific version constants, name operation functions onto Transaction, and patches a few bitcore functions that do not allow for altcoin compatability (specifically bitcore.Script.fromString and Transaction.prototype._fromNonP2SH). These will hopefully by replaced by native Bitcore functions as I work to improve Bitcore's altcoin compatability.
