==> smart contracts will be added very soon.
An experimental blockchain creation, mining, verification excersize.
Also on top of that is build AylaCoin where decentralized nodes in the network can exchange AylaCoin with each other.
in the mock/*.json files, you can find the mock data for the nodes and the transaction format.
This is the core blockchain logic where the AylaCoin is based on.
Flask requests
http://0.0.0.0:5000/${endpoint}
-> /mine_block
-> get_chain
-> validate
When a request is made to the endpoint '/mine_block', the node creates a new block and adds it to the chain. Minings is expected to be completed once the first 5 digits of the hashlib.sha256(str(current_proof**2-previous_proof**2 - 2**10).encode()).hexdigest() function are equal to '00000`.
When a request is made to the endpoint '/get_chain', the node returns the entire chain and also the length of the chain. If no mining is made before the request, the chain will only show the genesis block.
using the validate endpoint, the node will check if the chain is valid or not.
Basically an experimental custom cryptocurrency based on the blockchain.py implementation above.
-> /add_transaction ==> POST request
given the parameters sender and recipient and amount, the node will create a new transaction and add it to the list of transactions.
-> /connect_node ==> POST request
Takes the nodes from a JSON file (mock data is used), checks whether the json file actually contains any adresses. If there is at least one address, the node will connect to the node and add it to the list of nodes hence forming a network.
-> /replace_chain ==> GET request
replaces the chain with the longest chain in the network.
beware the sender and receiver which shows that the nodes are connected, the consensus is established and transactions are successfully made
