(https://github.com/bitcoin/bitcoin/pull/29325)
Given that the use of a transaction's nVersion is always as an unsigned int, it doesn't make sense to store it as signed and then cast it to unsigned everywhere it is used and displayed.

Since a few alternative implementations have recently been revealed to have made an error with this signedness that would have resulted in consensus failure, I think it makes sense for us to just make this always unsigned to make it clear that the version is treated as unsigned. This would also help us avoid

I don’t know if it’s robust to remove the CSV 1 and potential interactions of invalidated chain of transactions with `m_recent_rejects`.

Done, `CFeeRate` is the right format since we are representing fee rate.

>Shouldn't there be a check in CreateTransactionInternal that makes sure we don't make transactions above this feerate, and an arg passed to BroadcastTransaction? I also don't see a test case for it.

Agreed

I Added a check in `CreateTransactionInternal` in 0c9e0c5b2218c154b62275794b878af7e1457647.

No need to pass an arg to `BroadcastTransaction` if the transaction fee rate is above `maxfeerate` it will not read `BroadcastTransaction` so it will just be a dead code.

i think there is @petertodd ’s https://petertodd.org/2024/one-shot-replace-by-fee-rate to weigh as a pinning solution.
sounds to me slightly more robust than v3 policy as no malleability in the fee-bumping mechanism.
however the dynamic N replace-by-feerate window might be a mess for miners mempools.
whatever the solution (v3 or replace-by-feerate), i believe you will still have exploitable asymmetries for L2s.

I think `BroadcastTransaction can be called by RPC or by the wallet` is ambiguous in this case.
By which RPC?

`BroadcastTransaction` can be invoked by other components that will like to submit transactions to the mempool and relay them to peers, in addition to the wallet and RPC.
It's accessible through the node interface https://github.com/bitcoin/bitcoin/blob/717103bccec8d271f61f9cd6481b334bd9889146/src/node/interfaces.cpp#L341

Another instance in the tests which could be adapted to 0xffffffff:

Slightly related to this PR: since this currently doesn't produce a warning, was it ever considered to enable `-Wsign-conversion`?

Concept ACK on making transaction's `nVersion` unsigned, as that is in practice how it already behaves.

Would it make sense to also rename the field to e.g. `unsigned_version` or so, so that:
* Reviewing the diff makes it obvious whether any references to the field exist that aren't modified.
* Any future contributor who missed this change won't accidentally assume the field still has signed semantics?

For normal code I'd consider this measure overkill, but this is pretty fundamental con

This is insufficient to fix pinning in comparison to existing solutions: https://petertodd.org/2023/v3-txs-pinning-vulnerability

For example, at the moment the transaction fee required to get into the next block is about 23sat/vB, while the minimum relay fee of a typical mempool is 20sat/vB. So an attacker who simply did a straightforward pinning attack on an ephemeral anchor sp
