[Milestone] Bytecode similarity search

[kuzdogan]

To be discussed during the quarterly planning

Given an onchain bytecode, what is a matching (or similar) bytecode that has a verified source code? Now that we have a bytecode db we can do it.

The input would be a raw bytecode and the output would be source codes and maybe a degree of similarity?

Should be worth to have a look at the Blockscout bytecode database service for this: https://docs.blockscout.com/devs/verification/ethereum-bytecode-database-microservice

I read through this but it doesn't seem like they are doing anything special for the bytecode search. They just take into account bytecode auxdata from what I understood.

Yes I think they are not doing similarity but looking for byte-by-byte matches (except cborAuxdata).

Of course if we find a byte-by-byte match, that will be the correct response. The similarity search comes if it this fails
