> Or perhaps Rust Bitcoin could ship it as an example.

Yeah, right now it looks like this is just a few lines of docs and example code with the bulk being several imported rust-bitcoin dependencies. So I wonder what the benefits are to include it here, instead of somewhere closer where the majority of its (implicit) code sits.

This is a bit confusing. What does "back it up" mean? The wallet, the mnemonic? Also, I am not sure about the risks that users are exposed to now. I've only read the first section of https://github.com/bitcoin/bips/wiki/Comments:BIP-0039 and it mentions loss of funds. So I think it would be better to educate the users about how wallet incompatibilities can silently lead to loss of funds, instead of implying that a backup of the mnemonic is sufficient for recovery.

One more RPC worth mentioning here is `getblockstats` which is currently showing sat/vB in its `feerate_percentiles` JSON array.

I would find it much more helpful if it printed the integer values in sat/kvB as mentioned by @murchandamus .

Concept ACK

Good to document useful aspects of `Assume`.

💬 hodlinator commented on pull request "doc: clarify the documentation of `Assume` assertion":
(https://github.com/bitcoin/bitcoin/pull/32100#discussion_r2008737842)
This seems sufficient to me:
```suggestion
expression is always evaluated. However, if the compiler can prove that a
statement inside `Assume` is side-effect-free, it may optimize the call away,
skipping its evaluation in production. This enables a lower-cost way of
making explicit statements about the code, aiding review.
```

Motivation:

> `Assume` can also act as a lightweight debugging assertion, ensuring statements are tested e.g., during fuzzing—to catch violations.

Thanks, that's a good point I might have overlooked, that in a high fee environment, the tie break on weight is different than in a low fee environment.

Hmm that make sense now that you say it. sorting by density isn't strictly equivalent to sorting by value with weight as a tie break and as such would change the behavior of the search.

So, it sounds li

Right. It seems unnecessary to have Vulkan support on any platform right now, Windows has the DX stuff for rendering, MacOS has its own rendering thing, and i guess on Linux the common denominator is still something like GLES2.
