RLP Implementation

[sideninja]

Currently, the SDK uses RLP implementation from go-ethereum package which is huge!. I believe we would benefit from implementing RLP ourselves since that big dependency would be removed. Also RLP is something that wouldn't change.

There has been some work done for RLP integration in flow-go onflow/flow-go#2011
Keep an 👁️ on it

I agree with you 100%, from a performance perspective. RLP only requires about 8 code files, plus tests.

In addition to the heap thrashing addressed in onflow/flow-go#2011, the use of reflection and heap for walking the object graph is worth avoiding. Other forums online have suggested creating a kind of IDL -- a parser that will generate the appropriate code for generating struct and data object graph serialization. It's actually not hard to do, so it's on the radar. It would be much better if RLP code were forked (or appropriated somehow) to make this happen.

Is there any plan in the flow-go to do that? The forking/our implementation?
