This release merges upstream up to ethereum/go-ethereum@v1.12.0.

What's Changed

• Merge ethereum/go-ethereum release v1.12.0. #551

• Drops Kotti chain support. #552

  for syncing with Kotti, v1.12.12 can be used. In advance, this v1.12.13 can also be used by importing Kotti genesis in advance of syncing.

Highlights

• In this merge we had to revert the changes made upstream with regards proof-of-work removal.
• core-geth defaults to use Pebble as a backend if no existing database is found (ethereum/go-ethereum#27136). If a previous LevelDB database exists core-geth will keep using that, and if you must have LevelDB for some compatibility reasons, you can force it in Geth with the --db.engine=leveldb flag.
