pychains

Exploration in Python blockchains

This is a naive implementation of a Proof-of-Work blockchain, based heavily on https://hackernoon.com/learn-blockchains-by-building-one-117428612f46.

This is for educational purposes only and is expected to have copious bugs, faults, and inefficiencies.

Currently in place:

  1. Blockchain structure
  2. Proof of work mechanism
  3. Simple "Longest chain" Consensus mechanism.
  4. REST API for adding transactions and triggering block mining

TODO:

  1. Naive block propagation
  2. Smart block propagation
  3. Port to Crossbar, maybe.
  4. Stand alone, miner.
  5. Simple Wallet Implementation
  6. Simple coin and resource checking.
