RPC Component

This is by far the simplest component. Essentially this is a thin gRPC server which proxies all requests to the store and block-producer components.

Its main function is to pre-validate all requests before sending them on. This means malformed or non-sensical requests get rejected before reaching the store and block-producer, reducing their load. Notably this also includes verifying the proofs of submitting transactions. This allows the block-producer to skip proof verification (it trusts the RPC component), reducing the load in this critical component.
