I updated the `waitTipChanged()` and `m_tip_block` doc.

@maflcko which if-guard do you mean?

> @maflcko which if-guard do you mean?

I think probably this one:

```c++
// Wait for genesis block to be processed
if (WITH_LOCK(chainman.GetMutex(), return chainman.ActiveTip() == nullptr)) {
```

Removing the `if()` might help verify that `m_tip_block` is set reliably

Also, the ZERO workaround could be removed completely, ensuring that any interfaces will only be spun up after that point in init?

> ensuring that any interfaces will only be spun up after that point in init

It could, but I'm not sure if it's worth putting such a restriction on the interfaces.

Similarly we have `startupnotify` which happens at the end of init. If we also ensure that the interfaces are ready to listen _before_ this notification, then at least from an application launched with systemd (or similiar) we could expect them to wait for this signal before trying to connect.

If on

I noticed this issue while reviewing #30595, and started working on an [alternative approach](https://github.com/stickies-v/bitcoin/commits/2024-11/add-bounded-integer/) before @TheCharlatan made me aware of this PR. I thought it would be nice to introduce a new `BoundedInt` type, that avoids relying on input validation and instead forces the underlying value to be bound to a (compile time constant) certain range.

However, there were much

nit: `CCheckQueue` is used for other things than `ScriptCheck` (in test code), but I don't see a better place to put the log statement, and making it a non-refactor commit by e..g updating the wording to "Verification queue uses ..." is probably not worth it either, so disregarding this nit might be the best way forward.

Related (but not required for this PR, and currently a no-op), the below patch removing default value duplication would ensure the default `work_threads_num` value doesn't depend on argsmanager being used either:

Tend to agree for now. Having waitTipChanged wait for a tip to be connected seems like a natural thing to implement and might avoid the need for clients to poll the node on startup. But I think this check could be dropped in BlockTemplate::waitNext in #31283 (maybe replaced with an assert there) since it should not be possible to get a blocktemplate reference before the tip is connected. After #31283 it m

Apologies l0rinc. I think we are probably just misunderstanding each other. All the checks you are suggesting are possible with the approach I'm suggesting, and it should only make them easier to implement and understand. And I might not understand what approach you prefer since your first comment https://github.com/bitcoin/bitcoin/pull/31212#discussion_r1850778259 seems to want new tests to be in the same commit as the bugfix, but the last one https://github.com/bitcoin/bitcoin/pull/31212#discu

I think it's generically useful though. There are various types of applications that need to know when a new block is added to the chain.
