Good to see the high perf. It's a shame we're stuck with jsonrpc for all things ethereum
Oh the other thing that sucks is that reading grpc from browsers and react native is a PITA So tbh we might end up with a json rpc or rest api for hubs at some point
reth is supposed to pluggable enough to write your own endpoints if you need the extra perf, jsonrpc is… fine for a baseline standard
