.exe. Windows may show a SmartScreen warning — that's expected and explained below. Pick an install location, click through, and it's done in under a minute.
The installer is not currently signed with an Extended Validation code-signing certificate. EV certs cost several hundred pounds a year; we're working up to it, and it's one of the things a subscription helps fund. Until then, Windows SmartScreen flags any unsigned installer from a new publisher. It's a reputation thing, not a malware detection.
To install anyway:
If you're uncomfortable with that, you can verify the installer's SHA-256 against the hash published on the GitHub Releases page. If the hash matches, the binary is exactly what we published — and the source that produced it is also on GitHub.
Every release on GitHub ships with a SHA-256 hash. Check the downloaded installer matches before running it — takes about 10 seconds in PowerShell.
Full reproducible-build parity is in progress. That means you can currently verify that the binary matches what we published, but not yet that the binary matches a build from source you ran yourself. Reproducible builds are on the roadmap — when they ship, we'll publish build instructions here.
Community hubs stable, signed file manifests, mesh-pull live streaming, Dead Man's Switch with custom timers, mnemonic recovery polished, integration test suite at 80/80. Full changelog and older versions on GitHub.
