3rd Party Python Packages Required:

• Pycrypto 2.6 - https://www.dlitz.net/software/pycrypto/
  • WIN: http://www..voidspace.org.uk/python/modules.shtml#pycrypto
  • OTHER: See official site
• ECDSA - https://pypi.python.org/pypi/ecdsa

Note: If you are not using Eclipse as IDE, then you can ignore the two project files, using Eclipse will greatly simplify stuff though.

Added support for SIGHASH_ANYONECANPAY.

Few things to note:

• Testnet DNS resolved servers may be unstable for testing.
• After creating the signed transaction, should use bitcoin client to send the signed raw transaction to the Bitcoin network.
• Biteasy.com testnet status site is down.

Added support for multi-input transactions.

Successfully tested against TESTNET3 with the following transaction: https://www.biteasy.com/testnet/transactions/b11c5c3359087f6646b3ea2648bb9f33bfa7f1ea4e255b0ed92caafe23de79a0

Added configurations file to make parameter changes easier.

Successfully performed test against TESTNET3 by broadcasting the following transactions:

Rewrote most of the code forked from the version created by Ken Shirriff over at: http://www.righto.com/2014/02/bitcoins-hard-way-using-raw-bitcoin.html

There is still an issue when trying to broadcast transaction via TESTNET3, have not yet tried the MAIN NET yet.

• Run by executing transmission.py
• All the transaction details can be found inside the transaction.py file
• Message file helps the construction of the required messages needed to facilitate sending transactions.
• {publicKey,PrivateKey}.py files are required to generate keys within the keyGenerationLog.txt
• Keys generated here are cryptopgraphically secure, an improvement from Ken's previous code by adopting the use of the pycrypto package.
