Synchronize the evm changes in go-ethereum to Semux

[VictorECDSA]

Is EVM source code in Semux from the EVM module in the "https://github.com/ethereum/ethereumj"?
If so, consider that "ethereum/ethereumj" is currently no longer supported.
What about the Semux team thinking about synchronizing some of the evm improvements and bug fixes in go-ethereum to Semux?
Thank you!

No longer supported for eth new forks. Which also, afaik, semux is not supporting or planning to support.

I suppose we will evaluate new eth forked opcode's for VM as they come up.

What new EVM features are not synchronized to the Semux project?
For example, the blake2F precompiled contract in Istanbul fork, or those newly added instructions, and the instructions with changed gas consumption, and so on.
Does the Semux team have such a list?
Thank you very much!

We will certainly accept pull requests if someone wants to propose/implement Istanbul, but given low adoption, I'm not sure its high on dev teams list unless there's known vulnerability
