PeerCache

PeerCache is a distributed key-value data store built using Rust and leveraging libp2p and tokio libraries. Used the FloodSub protocol for efficient retrieval of stored messages across a decentralized network of nodes. The code is written to store "NFT" metadata with predefined fields (I wanted to get the implementation running quickly, so I made the data type concrete) but can be easily adapted to store any kind of data with minor modification to the code.

Note: The implementation may look hacky because I only intended to write this code for learning how to work with the rust-libp2p library and not to make a full fledged high performant distributed key value store.

#TODO: Update README

Instructions

  1. Install Rust v1.61.0-nightly (follow instructions here).
  2. Clone the repo: git clone https://github.com/h3lio5/rusty-messenger.git
  3. Start the p2p network by running the command cargo run RUST_LOG=info cargo run in multiple terminal tabs.
  4. Interact with the network using the following commands (run the commands in different terminal tabs)-
  • LIST PEERS: Lists all the peers connected to your node
  • CREATE NFT <collection_name>|<item_id>|| (NOTE: all the fields are necessary)
  • GET NFT ALL: lists all the NFTs stored on the network
  • GET NFT <collection_name>: Lists all the NFTs of the requested collection
