Description

I'm working on Part 2. So I thought I'd share a bit of the roadmap. I'm aiming on publishing sometime in the next week but still have a few hurdles and could use your expertise.

Hop on to our Slack if you wanna get involved.

  • Basic Contract (P2P Protocol)
    • Endpoints:
      • get_chain, post_transactions, get_nodes, post_block, ...
  • Heartbeat Loop
    • Ported to aiohttp over Flask
    • asyncio allows us to have an event loop for introspection (and pinging other nodes)
  • Transaction Verification
    • Using Python NaCl to generate a public/private signing key pair: private.key, public.key which should be generated before runtime.
    • Would still appreciate thoughts on this method
  • NAT (Opening ports on Router, like uTorrent/Transmission/Bitcoin Wallet): uPNP, NAT-PMP, PCP...
    • Attempting to open a port on the router at runtime using one of these protocols
    • Bogged down on this one, poor python library support unsure how to proceed for now
    • Would appreciate help on this one

Research direction
This is a roadmap for implementing Part 2 of a blockchain project. The issue outlines tasks including transaction verification using PyNaCl and NAT traversal. The maintainer is seeking help on the NAT part and general thoughts on transaction verification. The repository is a Python blockchain project (dvf/blockchain). Focus on the incomplete tasks: implementing transaction verification with PyNaCl and exploring NAT libraries in Python. Check the Slack invite for discussion. No existing PRs or assignees.
