Walletwasabi: ARM/AARCH64 Compatibility

[Gfloresechaiz]

Hi,

Wasabi isn't ARM64 or Aarch64 compatible for the moment. I was wondering what would be needed for this to be a reality? Will a release of .NET Core 3.0.0 and an eventual Wasabi upgrade be sufficient or are there other components which will need upgrades?

Thank you for taking the time to evaluate my issue.

Let me see, there are probably millions of issues with this, but let me check our dependencies if they work or not.

• Tor should work, although there are some contradicting recent information on it: https://www.reddit.com/r/TOR/comments/blrx1h/building_tor_browser_on_arm/
• .NET Core doesn't: https://github.com/dotnet/announcements/issues/82
• HWI doesn't work out of the box either: https://github.com/bitcoin-core/HWI/releases
• Bitcoin Core should work. (Not a dependency yet.)
• Avalonia? NBitcoin? both depend on .NET Core.

There are instances of Avalonia & .NET Core working on Raspbian but i'm not privy into the grittier details.

Only supports ARM32 i guess but someone needs to check that (don't have a Pi atm).

Tor certainly works on Aarch64, I have it running on many rock64s for months. The link you attached is about the Tor browser, so it shouldn't apply to Wasabi but maybe that's the dependency and I'm mistaken

• .net core 3.0 will support aarch64 and I've read on Twitter that Nicolas Dorier will update Nbitcoin when it's full released which should be soon iirc

Thanks for the research!

@jmacato right, certain instances of .net can currently run on arm32 , will try to run Wasabi on a Pi later this week but doubt that it works.

I tested this on my Pinebook Pro and i can confirm that it is stable on coinjoin/normal wallet usage. HWI is inoperative. Tor needs to be a daemon/service in the host system.

I managed to build it on a old Raspberry Pi 3 B+ (ARM32 version of .NET Core 3.1), but seems to have failed the test:

Hey I'd be keen to get this running on a pinebook pro - you're link seemed to be dead, is there any more info on this?

[jmacato]

@humansinstitute please re-check, i've deleted the branch and i've restored it now. Be aware that there's no official support from us for ARM64.

[humansinstitute]

Hey thanks will have a look.
I actually ended up working around this by install wasabi on an old x64 laptop I use as a linux server and sending the app back to the PBP through X11 forwarding :)

Technically it is possible to make it work but we decided on the dev meeting to not support ARM devices as it would bring a maintainability/testing need that our team cannot fulfill.
