p2pIM is a peer-to-peer instant messaging prototype that uses proof-of-work to deter spam, with message storage capacity determined by PoW difficulty and time-based decay. It includes two Python server implementations, command-line tools for message generation, and a web UI for basic interaction. The project explores an interesting combination of P2P and PoW for spam resistance, but remains a rough prototype with minimal documentation and testing.

Target audience: backend developers, distributed systems enthusiasts, security researchers
