@Patoshiパトシ if your debug.log file reports `progress=1.0000`, then your node has synced up to the longest chain that it is aware of. You can also run the command `bitcoin-cli getblockchaininfo` to see more details related to your node's view of the chain.

There is no need to resolve anything - some miners create arbitrary versions to attempt to speed up the mining process, as it gives them an additional field in the block block header to alter without having to recalculate the merkle root and other fields.

This is harmless, provided they aren't producing invalid blocks for version 2, in which case the block would be rejected
