Additional EIPs to consider for kitabu

Berlin

Openethereum compatibility

Config examples:

f13fa10b8a/crates/ethcore/res/chainspec/test/basic_authority.json minimal authority example
f13fa10b8a/crates/ethcore/res/chainspec/test/berlin_test.json full berlin hardfork
f13fa10b8a/crates/ethcore/res/chainspec/goerli.json clique config example

Several EIPs do not seem to be included among the keys that are parsed through config. We should probably ask why that is the case.

@willruddick for the short term we know too little about evmos.

We don't know how stable is it, nor whether anything important is based on currently running instances.

We don't know about the performance of it; it most likely wraps a significant portion of geth, and geth is very heavy.

We can't use this with other ethereum clients, that locks us in to the cosmos ecosystem.
