Instructions

"Please run the init.py module to run a test of the libs"

Guidelines

• All classes and functions are documented, do take a look in case you do not understand any implementation logic.
• Wallet() to create a SHA256 generated wallet. It will ask you to put some gibberish to increase entropy, but this is not required.
• Transaction(wallet,inputs,outputs) to create a new transaction.
• NetworkNode(node_ip, wallet_node) to create a new Node on the BlockChain Network (this is just for semantic consistency purposes, there are no real Network capabilities implemented at this moment)
• This ~NetworkNode object will be the one that will search for a nonce, will verify Transactions and will generate a new block.
• This ~NetworkNode object will be the one responsible for creating as Merkle Tree using the ~HashedNode object and the create_tree() functions
• Finally, the ~NetworkNode creates a new ~Block object. The creation of this ~Block will be different if its defined as is_genesis = True on creation. In this case we will use the default value '0' as previous hash for the creation of the Genesis ~Block

All Objects implemented within this repository have a specialized str() implementation to facilitate the hashing of the objects. Feel free to print some objects as a string!
