Provide a brief description of the functionality you're trying to implement and the issue you are running into.

Hi, i'm a developer for lachainzk, i'm currently working on adding support to the external node for the contract verification api, this api now only lives in the main node rpc. We don't want to expose the main node rpc publicly, so our only option for contract verification is to add the api to the EN.
I would like to know if contract verification data is exchanged between nodes, or does it only live on the main sequencer database.

Thanks.

Hey @alfarkas. I'm pretty sure that contract verification data isn't exchanged and indeed lives only on the main server. This is relatively legacy piece of code. And I would say usually such info as contract verification should live on the Block Explorer side, rather then the chain server.

I think is going to work, i've been working on this since last week and just now i was able to make it return the zksolc versions. In deed it required messing around with the code a little bit. I still need to see if contract verification works. Would this feature be something you'd be interested in adding to the original code once is ready? I think this is a easier and more straightforward way to remove contract verification from main node, but maybe in the future i could also try to implement it it in the block explorer which would be a better approach but probably more complex.

Sounds good, I'll share it with the team!
