##Setting up your own Bitcoind Node

  • Install Bitcoin-Qt
  • Edit bitcoin.conf server file with
    • server=1 to activate server
    • set a username and password, rpcusername= something, rpcpassword= somethingelse
    • set the server url (probably set as localhost) to local variable "node_url"
    • set the node username as local variable "node_username"
    • set the node password as local variable "node_password"
    • write txindex=1
  • Test with
    • python
    • import node
    • node.connect("getblockcount", []) this should return the last block
    • or merely perform py.test in the shell since the node-connection is tested

##Library Tools with Examples

###ADDRESSES.PY #####Get unspent outputs for address

  • addresses.unspent(public_address)
    • Returns an array of unspent outputs for an address.

###BITSOURCE.PY #####Translate a transaction input script to a color address according to the Open Assets protocol

  • bitsource.script_to_coloraddress(script)
    • Returns the color address

#####Read a Bitcoin Transaction for OPRETURN DATA

  • bitsource.read_tx(txhash)
    • Returns the OPRETURN message, Value in Satoshi of transaction outputs

#####Parse metadata from an OPRETURN for Open Assets Content

  • bitsource.parse_colored_tx(metadata, txhash_with_index)
    • returns a dictionary detailing the colored coin meaning of this transaction, issuance of coins, transfers, amounts, etc.

###TRANSACTIONS.PY #####Write Raw Transaction, Primitive Steps

  • transactions.make_raw_transaction(fromaddress,amount,destination, fee) ONE OUTPUT

    • returns an unsigned bitcoin transaction taking ALL unspent outputs for fromaddress. It sends the BTC amount to the destination, and returns the leftover minus fees to "fromaddress"
  • transactions.sign_tx(unsigned_raw_tx, privatekey)

    • Returns a signed bitcoin transaction. All inputs are signed with the given private key.
  • transactions.pushtx(rawtx)

    • Pushes a signed Bitcoin transaction to your connected Bitcoin Node
  • transactions.pushtx_toshi(rawtx)

    • Pushes a signed Bitcoin transaction to Coinbase's Toshi Node API

#####Send OPRETURN transaction

  • transactions.send_op_return(fromaddress, destination, fee, message, privatekey, specific_inputs)
    • Writes and sends a Bitcoin transaction to destination with an OPRETURN including message. Specific_inputs refers to an array of inputs to use as gathered from addresses.unspent(publicaddress)
