Great start! Thanks for continuing to do this man. I have not tested on my machine, responding to screenshots below.
Top-tier PR write-up, kudos! My main gripe still is that 'load/generate snapshot' makes no sense in Connection Settings. Otherwise looks good.
Isn't the snapshot generated a pre-decided block height only? not the current block height?
Suggested copy: "A snapshot captures the state of the bitcoin network up to a certain date in the recent past. It can be imported into other bitcoin nodes to speed up their initial sync.
Perhaps the "Rewinding" text is placeholder. Should be something like: You can continue using the application while the process continues in the background.** Good to have would be to show some a % progress number
The View File button is awesome! Consider adding a Done button too that will send the user back to home screen/block clock... |
in the figma design where would you idealy prefer these options would be placed under? |
Great suggestions will update with the next push |
Could you share some design ideas for this? |
Could you update the figma to reflect that? |

@GBKS could you take a look at the current iteration of the design and user flow, and le me know your thoughts? |
|
Nice progress here. I just tried to test and just see the message that IBD is not complete: 
However, the block status tells me it's all synced, as well as the CLI: 
The signet explorer also showed this block as the latest one. Do you maybe know what the problem might be? On a different note, my assumption was that we show either snapshot import (during IBD) or snapshot creation (post-IBD). We only need one at a time, right? |
Thanks for testing. Ok going to take a look I think I know what the issue is
Yep that's correct. That said, in terms of display if the user has loaded a snapshot my assumption is that we still want to display that, is that correct? (see screenshot below) Connection Settings Snapshot Loaded
|
Makes sense. On the flip side, if they *did not load a snapshot during IBD, the green check icon should not be present. (the Load Snapshot text has could be greyed out too). The description part could read "Cannot load a snapshot because sync is already completed". |

with fd78f7e rebased and addressed @GBKS feedback (please see screenshots below) Generate Button appears after IBD completion
Next: will address the use case that @yashrajd mentioned...
|
|
Let's clarify the situation around having an imported snapshot. Is there any user benefit to showing that a snapshot was imported, after the import is done? Of course, during the import, the user wants to see progress and at the end they want to see a confirmation that it was completed successfully. But after that, is there any reason to keep this note around? |
Great questions, going to let @yashrajd respond first... then will share my thoughts |
I don't have a strong preference as I said earlier, but here's why I think it should be there:
|
|
Thanks @GBKS and @yashrajd for the feedback. So got a compromise in the form of 3 potential use cases:
Please let me know your thoughts? |

@yashrajd we're not removing anything and it's not a marketing thing. There is a single item for this feature that is always visible and shows the appropriate state. If you can generate a snapshot, it shows that. If you can't, it shows that you can import a snapshot. It's one or the other, or am I missing something? |
|
TL;DR: IMO it's just a couple of list items that don't take up prominent or important space. They can serve multiple functions (as actionable elements, show state: enabled/disabled/progress) and we always display both, it even serves as marketing/education/communication. Happy to mockup different states if @D33r-Gee needs it.
my impression is that you are saying: the Load Snapshot list item should be removed after snapshot has been imported. sorry if I misunderstood you & don't have to read the stuff below .
|
Yes that would be helpful to visualize the different use cases/states. |

- Extend node interface with virtual functions for UTXO snapshot loading - Add signal mechanism to monitor snapshot loading progress - Include predefined signet UTXO dataset in chainparams for validation
This introduces a Rewind Progress notification so that it is available when generating an AssumeUTXO snapshot through the UI.
