descent-collective/ozi

Ozi is an application run by nodes(Descent price feeds). It broadcasts signed price messages through a network of peer-to-peer nodes over the gossip-sub protocol of libp2p.

POC for using libp2p gossipsub protocol to broadcast signed price messages for relayer clients to pick it up and send to the oracle smart contract.

TODO:

• use kademlia for peer discovery. right now we do it by pinging a peer. see libp2p/rust-libp2p#2447
• Get price for a particular collateral pair(e.g USDC/NGN) from listed exchanges(e.g. cryptocompare)
• Sign price data using nodes private keys
• Use variables from config to make API calls to exchanges.

usage

In one terminal:

$ cd ozi && cargo run -- m "hello"

The following will be printed:

Listening on < address >

---

In another terminal:

$ cd ozi && cargo run --m "hello from 2" -p < address >
