Add Signet and testnet4 launch shortcuts for Windows #26334

Sjors commented at 3:05 PM on October 18, 2022: member

This makes it easier to launch Signet and testnet4 on Windows. Follows the same pattern as testnet.

Before:

After: <img width="500" alt="signet1" src="https://user-images.githubusercontent.com/10217/220358057-d9efc532-272c-45e7-81fa-3a52f58a0f29.png"> <img width="527" alt="signet2" src="https://user-images.githubusercontent.com/10217/220358067-62b3b76f-604a-4163-9d35-c903fff29df0.png">

(the testnet4 icon is the same as testnet3, not in the above screenshot)

Concept ACK

Tested it on Windows and it works as expected except the color of logo for signet.

Looks like I need to set the correct yellow color.

jarolrod commented at 7:03 AM on October 19, 2022: contributor

we have actual ico files under res for the main and testnet icons, you would need to introduce a bitcoin_signet.ico with the correct yellow hue applied under src/qt/res in order to introduce the correct icon.

Looking ahead, I'd like to move away from having these different launchers to being able to select the chain from within the gui.

If you want a shortcut, please figure out a way to resolve this.

On my list to rebase, fix the icon color, and reduce potential confusion. I have a Windows setup now.

Sjors commented at 11:27 AM on February 21, 2023: member

I added the word "test" to the application name.

Since Bitcoin Inquisition uses the default Signet to deploy several proposed soft forks, I think it's useful to offer easier access (which requires the Inquisition folks to rebase after this is merged).

See #8285 for additional context.

I generated the icon from the mainnet icon by applying the same hue and saturation adjustments:

https://github.com/bitcoin/bitcoin/blob/94070029fb6b783833973f9fe08a3a871994492f/src/qt/networkstyle.cpp#L22

Though the -modulate command uses percentage instead of degrees, so it was a bit confusing to convert:

convert  src/qt/res/icons/bitcoin.ico -modulate 100,87,119.4 src/qt/res/icons/bitcoin_signet.ico

I added a screenshot in the PR description.

The big icon looks correct, but the mini version in the search result does not. I probably need to change the ImageMagick command somehow. I could also try using the Testnet icon as the basis (and rotate the hue in the other direction).

I think I found the right incantation, using the high res PNG as input:

convert src/qt/res/icons/bitcoin.png -modulate 100,87,119.4 -define icon:auto-resize="256,48,32,16" src/qt/res/icons/bitcoin_signet.ico

I updated the PR description screenshot.

I noticed that testnet has 4 icon resolutions, which I've used for signet too. But mainnet has 9. I could regenerate that one, but it would only save 11kb.

Most users won't know what "signet" means, and it isn't self-explanatory like "testnet"...

Most users wont use it and it just helps devs and power users on windows. They know what signet means. Everyone else clicking on it is same as downloading a malware instead of bitcoin core which is not something this repo needs to solve. First match in search is always "bitcoin core (mainnet)" and even that would open other network if bitcoin.conf has other network set.

So this NACK makes no sense for windows users.

NACK for "test signet"

signet already helps to know its NOT mainnet

Sjors commented at 5:47 PM on February 21, 2023: member

I don't see any harm in adding the word "test". A user who searches "bitcoin" will see the "signet" entry in their search results and wonder what it is, perhaps even worry about it. Without the word "test" the only two ways to figure out are to google "what is signet" or to launch the application.

I don't expect most users to know what "mainnet" is. They obviously know what Bitcoin is, but they may not know that one or more test networks exist.

If someone doesnt know what is mainnet they wont use bitcoin core as a wallet.

Perhaps the Bitcoin Design community will have a view on the wording. I'd go with standalone "signet" but I haven't done any user research on whether this isn't sufficiently informative.

Can just reuse the testnet icon to save 43.4kB in the git repo? Doesn't seem worth it to burden every clone forever just so that a color in a test-only picture is of a slightly different tone.

Sjors commented at 9:19 AM on August 14, 2023:

Or we could just drop testnet3 :-P

I find the difference in color useful enough.

maflcko commented at 9:22 AM on August 14, 2023:

I find the difference in color useful enough.

Then, it would be better to have a tiny script in the build process to create the .ico, no? This would make it reproducible, documented and easily modifiable, without on each modification bloating the git repo by 50kb

Sjors commented at 9:30 AM on August 14, 2023:

The incantation is in the commit message. Adding a script makes sense, but I'm not familiar enough with the (native) build tools to know where to add it. This particular command would also add a dependency to imagemagick (if we don't use it already), though I'm sure the operation can be done with other tools if needed.

Seems better to do in a followup and generate the testnet icon that way too.

On a second thought, I wonder what the target audience is. Someone aware of a test network, and wanting to use it, should be able to create a shortcut themselves? Creating the shortcut should be the easiest of their problems to get started with a test network.

Sjors commented at 1:20 PM on February 13, 2024: member

Creating a shortcut is easy, but creating an icon with a non-confusing color is not.

I would also expect not-super-tech-savy people to be testing applications on custom signets, e.g. testing a vault GUI on Inquisition. I would hope they don't use Windows of course :-)

Concept ACK, i think it's important that signet gets its own launch icon if testnet has, it's more useful for testing than testnet. The other option would be to keep only the mainnet icon. But i think there's value in making windows users aware of these kind of things (so they don't reinvent wheels, or, test on mainnet 😅 ).
