Poly RPC Prototype

Essentially a proof of concept of a multi-protocol RPC sub-system for rusty-kaspa.

This demo features:

• Trait RpcApi (initial work of Aspectron) exposing a protocol-agnostic API
• rpc-core RpcApi server responsible for fetching data from consensus
• rpc-grpc RpcApi service and client implementing (partially) the protowire RPC from kaspad
• Notification system with following pipeline: consensus -> rpc-core server -> rpc-grpc service -> rpc-grpc client -> client code

Limitations

The gRPC implementation at this stage should be considered essentially a proof of concept. It is limited to 2 queries: get_block and get_info.

The same is true of the notification system that only implements BlockAdded.

The whole rpc sub-system is not actually connected to consensus for now, neither for queries nor for notifications.

The client code requires an actual go kaspa node in order to demonstrate inter-operability and backwards compatibility.

Playing the demo

To run the prototype:

• Open 2 terminals and run respectively following commands:

  1. cargo run --bin server
  2. cargo run --bin client -- -a http://<kaspad_ip>:<rpc_port> (ie. -a http://192.168.1.233:16110)
