> The only non-constant in the VERSION message we send is the peer nonce

Yes and this can be used for fingerprinting, because we disconnect incoming connections that match an already existing nonce.

And I wouldn't be surprised if there are more ways to fingerprint in the version handshake. This will also end up being a maintenance concern going forward, mostly as a burden

while here, maybe test that assertion

Looking at `-ftime-trace=/tmp/`, I don't think there is anything that can be done, other than to nuke boost, or to define a smaller limited interface of our boost usage in a new header and hide the boost includes in the corresponding cpp file?

Concept ACK.

I've not reviewed the code in detail yet, but this is a nice followup to #28060.

It seems to work well so far. I wrote a quick-n-dirty [python script](https://gist.github.com/willcl-ark/d1dd7d80d4581671aa38157960a87ba7) to manually xor my data dir using the same 8 byte key from this pull, and Bitcoin Core at commit fa3c1d230a didn't have any problems reading the xored blocks or key afterwards.

This makes compilation of wallet.cpp use a few % less memory and time, locally.

Created in the context of https://github.com/bitcoin/bitcoin/issues/28109, but I don't think it is enough to actually fix this problem.

Guess that you wrote this because you saw it on an unit test?

I'm not seeing how this could be possible during the regular node initialization process. We aren't signaling any block prior to initializing the indexes.

In ba30b60b:

Isn't this conflicting with the `StartBackgroundSync()` call?

Let's say that there are new blocks on the notifications queue at this point. By not setting the `m_synced` flag, we allow `ThreadSync()` to start.
This former one might have some work to do if some of the queued blocks notifications were processed in-between `Init()` and `StartBackgroundSync()`. Then, while this is being done, the validation queue thread might end up setting `m_synced=true`. Which would enable the

No, it I believe it happens pretty reliably when you use `-reindex-chainstate`. I saw it reliably when I ran the `test/functional/feature_coinstatsindex.py` "[Test that the index works with -reindex-chainstate](https://github.com/bitcoin/bitcoin/blob/2fa60f0b683cefd7956273986dafe3bde00c98fd/test/functional/feature_coinstatsindex.py#L238-L240)" test and had
