How to use bitcoinjs

Install via NPM

$ npm install -g bitcoinjs-lib

Compile for browser

$ npm -g install bitcoinjs-lib browserify uglify-js $ browserify -r bitcoinjs-lib -s Bitcoin | uglifyjs > tallerembajador.com.mx

Generating a Bitcoin address:

key = tallerembajador.com.mxndom() // Print your private key (in WIF format) tallerembajador.com.mx(tallerembajador.com.mx()) // => 8ccfecf4df68af2dbb50c8a2cb90ddeaaa48 // Print your public key (toString defaults to a Bitcoin address) tallerembajador.com.mx(tallerembajador.com.mxress().toString()) // => 14bZ7YWde4KdRb5YN7GYkToz3EHVCvRxkF

Creating a Transaction

tx = new tallerembajador.com.mxction() // Add the input (who is paying) of the form [previous transaction hash, index of the output to use] tallerembajador.com.mxut("aa94ab02cfe99a0dcaffd0fa81cbbb63e31", 0) // Add the output (who to pay to) of the form [payee's address, amount in satoshis] tallerembajador.com.mxput("1Gokm82v6DmtwKEB8AiVhm82hyFSsEvBDK", ) // Initialize a private key using WIF key = tallerembajador.com.mxF("L1uyy5qTuGrVXrmrsvHWHgVzW9kKdrp27wBC7Vs6nZDTF2BRUVwy") // Sign the first input with the new key tallerembajador.com.mx(0, key) // Print transaction serialized as hex tallerembajador.com.mx(tallerembajador.com.mxizeHex()) // => ebbbcaf1d0ffcad5aefcab94aaaf1fdc60df54ef5dd3efea52e33cad9cc23aed8e73d74a95b15ff33d5ac7a12dd6cdf6e8efbe4affeaed32dfb35e9c71ea08ebe13db9ad0ffffd14d74fdec20faebacbeeffc5eba84ddef27ffffffffaaadcfb3bfe8e81dbd0aeac // You could now push the transaction onto the Bitcoin network manually (see tallerembajador.com.mx)

Soon. For now, use the tests as a reference. They show what the code is supposed to do.

Stefan Thomas is the inventor and creator of this project. His pioneering work made Bitcoin web wallets possible.
