[META] make ethereum's RPC using protobuf messages #140
Description
json is too verbose and too difficult to parse. We have to use binary format to pass data from embedded targets.
- evaluate available protobuf libraries suitable for an embedded system
- port JSONRPC messages to protobuf definition
- make a proxy that accepts protobuf-encoded message on one side (using HTTP as transport for now) and translates the request to JSONRPC (this can be done in python/flask)
- create protobuf RPC library for the embedded part
- integrate the proxy and the library
