If commented out, better to remove it completely.

I left it as its still helpful for memory/performance profiling to see from where we call it too often...
But Ok to me to remove it as well...

I guess it can be safely removed as it is checked during the write procedure anyways.

Got enabeld in a later commit again as it was required at some cases (resync from resources i guess, or regtest fresh start)

I think we should move the block snapshots to Git LFS. If I'm not mistaken adding p2p/src/main/resources/BsqBlocks_BTC_MAINNET/* filter=lfs diff=lfs merge=lfs -text to the .gitattributes file should do the trick.

utACK - besides the Git LFS config changes. As soon as it is in and rebased to master after merging #5782 I'll run it again against Mainnet before merging.

There are also two minor Codacy complaints regarding an import statement: https:/bisq-network/bisq/pull/5790/checks?check_run_id=4111754368

Remove blockHashes set from daoState

Avoid unnecessary serialisation/deserialisation cycle
6990486 
For the snapshot we create a deep clone by protobuf serialisation.
We do not need the deserialisation back to the java object as it is
only kept in memory for later persistence where we need to do protobuf
serialisation again. So we can skip that cycle and safe a bit of
time at creating and persisting snapshots.
@chimp1984
Persist bsq blocks as buckets of 1000 blocks

Improve logging

Add BsqBlockStore to protobuf

Remove DaoStateMonitoringService field

Do not persist the blocks in daoState anymore.

This improves persistence performance and reduces memory
requirements for snapshots.

@ripcurlx
Re Codacy complaints: Unnecessary use of fully qualified name 'protobuf.BaseBlock' due to existing import 'protobuf.BaseBlock'
I intentionally kept the protobuf package to make it clear that we dont use the java model here but the proto data.
So I prefer to keep it. I find those compaints anyway questionable. Leaving package qualifiers can help in certain context to improve readibility IMO.
