Use Msgpack encoded Bytes instead of JSON to transfer data

[Niraj-Kamdar]

If RPC call give bytes as response, it may not be JSON serializable in some languages.
So, we should use msgpack instead of JSON.

Current schema

request(method: String!, params: JSON, connection: Connection): JSON!

Proposed Schema

request(method: String!, params: Bytes!, connection: Connection): Bytes!

hey @Niraj-Kamdar I think that since the request method is just an JSON-RPC call to an Ethereum node, it makes sense to return JSON. If a method's response is in bytes, those bytes will be received as string

That's not true for every implementation. Checkout web3.py

can you be more specific about what should I check? I've seen & used the library but I am not sure what you mean exactly

[Niraj-Kamdar]

call eth_getTransactionReceipt RPC method and try to stringify the result. You can do this by invoking request method which will fail.
