So the below is the function I'm running. I'm sending in the key for this bitcoin address
16WBguy6KVyTGnF4KX7Vmdx8ztj4wENh4W
and the message
bkawk
to this function
// Require the packages that we need.
var bitcoin = require('bitcoinjs-lib');
var request = require('request');
var blockchain = require('blockchain.info');
var blockexplorer = require('blockchain.info/blockexplorer');
// Export the module and pass in the message and the WIF
exports.opReturn = function (message, WIF) {
// Setup the new promise
return new Promise(function(resolve, reject) {
// Set the network to the main net not test
var network = bitcoin.networks.mainnet;
// Generate the keypair
var keyPair = bitcoin.ECPair.fromWIF(WIF);
// Get the address from the key pair
var address = keyPair.getAddress();
// Ask blockchain.info for all the unspent transactions
var url = 'https://blockchain.info/id/unspent?active='+address;
request(url, function (error, response, body) {
// Check the request didn't error and we got a 200 ok back
if (!error && response.statusCode == 200) {
// Parse the results
var body = JSON.parse(body);
// Build a new transaction
var tx = new bitcoin.TransactionBuilder(network);
cont...
// Buffer the message into hex
var data = new Buffer(message);
// Prepare the message
var dataScript = bitcoin.script.nullDataOutput(data);
// I Suspect there is problems here!!
var unspent = body.unspent_outputs[0].tx_hash_big_endian;
// Add the unspent tx to the output
tx.addInput(unspent, 0);
// Add the unspent transaction to the first output
tx.addOutput(dataScript, 0);
// Add our address to the 1st output - Must I use another address or no?
tx.addOutput(address, 1000);
// Add our address to the 2nd output - Must I use another address here too?
tx.addOutput(address, 1000);
// Sign the transaction
tx.sign(0, keyPair);
// Convert to hex
var txRaw = tx.build().toHex();
var txId = txRaw.getId()
console.log(txId);
// Resolve the promise
resolve(txRaw);
// Log the hex
console.log(txRaw.toHex());
} else{
// if there was an error reject the promise
reject(error);
};
})
}); //-- END PROMISE
};// END FUNCTION
the above console.log is giving me this transaction hex

Pushing it to https://blockchain.info/pushtx returns...
None Standard Script Output OP_RETURN 626b61776b
And pushing here http://blockr.io/tx/push results in
There was an error pushing your transaction to network!
Did you sign your transaction? Is this double spend? Have you already sent this transaction?
but then when I check it here I don't see the transaction. Any Ideas?

Here is an example of a successful transaction made from Colu
