Similar to NoahCoin v1, but with security. There is now no way to steal other users money without knowing their private key.

• Install new dependency ecdsa with pip (pip install ecdsa) or another tool
• Clone the repo and navigate to its directory
• Checkout the noah/crypto-project branch
• Change directory with cd crypto/currency/scripts
• Make files executable with chmod +x run.sh stop.sh
• Run the code with ./run.sh. Now the flask server should be running on localhost as well as the local network on ports 5001 through 5004
• Begin calling endpoitnts. Open the Postman collection json file noahcoinv2.postman_collection.json in Postman and make requests there or call them another way

• Generate a wallet
  • Private key (32 char hex)
  • Public key (32 char hex)
  • 'NoahCoin address' (Base58 encoded 27-28 char string)
  • Static methods for step by step generation
• Make transactions
  • They must be signed with a private key. Signatures will be verified with public key.
  • Sender address must match public key of transaction
  • You cannot send a negative amount of NoahCoin or more than is currently in your account
  • Transactions can be from the miner node (call the POST new_transaction_from_node endpoint) or from another node on the network (POST new_transaction with all of the other fields)
  • The new_transaction_from_node endpoint will only function if called from the local machine. The code will check IP address, so you can steal from the miners!
• Check on transaction status
• Delete transaction in pool
• Get user account value
  • Sums up all of the transactions they have made in the chain
• Get transaction pool
• Connect node
• Get largest chain
  • Replaces local chain with the largest valid one on the network
• Check chain validity
  • Ensures users can afford all transactions, all signatures match, all transaction public keys match their senders, transaction hashes and block hashes are matched, and no data has been tampered with
