Is there a one-to-one correspondence between an Ethereum execution layer node and an Ethereum consensus layer node？ #30407

I want to know if there is a one-to-one correspondence between an Ethereum execution layer node and an Ethereum consensus layer node, and if so, how it is implemented; If not, will there be a one to many or many to one situation？

Unsure what you mean.

Currently one CL can use only one EL at a time, though any CL can use any EL (via the engine api).

If you mean whether one client of a type could use multiple other type at the same time, then:

I don't think there will ever be a way for multiple CLs to use a single EL.
For a single CL to use multiple ELs, I have a proposal https://gist.github.com/karalabe/47c906f0ab4fdc5b8b791b74f084e5f9, which doesn't run full fledged ELs, rather just the important bits.
