15,000 words from 12+ year old emails?

Further specification is needed to explain how this has anything to do with Peter's control of his DNS seed. All I see are discussions of how different aspects of Bitcoin work.

🤔 l0rinc requested changes to a pull request: "refactor: Return uint64_t from GetSerializeSize"
(https://github.com/bitcoin/bitcoin/pull/33724#pullrequestreview-3393067389)
I like the focused commits with good explanations.

I would like to suggest to consider something slightly simpler that may fit the data better.
We're storing these serialized sizes as 64 bits to avoid having to cast when we multiply the value. But we're always serializing these sizes as either variable length ints or 32 bit ones, so it's a bit awkward that a method returns 64 bit value and we just have to remember to cast them to 32 at call sites (otherwise they would serialize incorrectly in a

Can we migrate the constant to 64 bits as well?
https://github.com/bitcoin/bitcoin/blob/fab75c2d0332fdb25030abb441363478cd486dc5/src/rpc/blockchain.cpp#L1907
```C++
static constexpr uint64_t PER_UTXO_OVERHEAD{sizeof(COutPoint) + sizeof(uint32_t) + sizeof(bool)};
```
Or if we will go the other way and mirror storage and only up-cast when needed, it would be:
```C++
static constexpr uint32_t PER_UTXO_OVERHEAD{sizeof(COutPoint) + sizeof(uint32_t) + sizeof(bool)};
```

Presumably it would also be possible to use the same signature on a p2wsh tx (`<sig> SWAP CHECKSIG`) which would lose the `CONST_SCRIPTCODE` requirement. Could also presumably just have the script be `CHECKSIG` and provide both the pubkey and the short signature in either p2sh or p2wsh.

@willcl-ark you can also look at the memory model and seeing if/how you can make the cache more parallel during block validation. IIRC there is some unnecessary locking which can be eliminated/reduced to something like one acquire/release per thread and a single thread holding a unique lock to prevent writers.

> But as you said, the thread sanitizer would likely complain about that. We’re accessing the same variable from different threads (main and worker).

It won't complain if we synchronize access to the same non-atomic variable, which we do here because we lock when calling `Submit`.

The new accounting options introduced in https://github.com/bitcoin/bitcoin/pull/32582 can be quite heavy, and not needed when debug logging is disabled.

`PartiallyDownloadedBlock::FillBlock()` and `PeerManagerImpl::SendBlockTransactions()` accumulate transaction sizes for debug logging by calling `GetTotalSize()` in loops, which invokes expensive `GetSerializeSize()` serializations.

Guard the size calculations with `LogAcceptCategory()` checks so serialization only occurs when compact bl
