blastQR
Truly offline file transfers through animated QR code sequences. It's one of the projects I've been working on for the past 2 years: blastQR. Currently hitting peak transfer speeds of 1.4MB/s and I'm excited to keep pushing it further. Some of the more interesting use-cases I was thinking about are large-screen broadcasts so people can receive information during digital blackouts, government cutting off internet, etc. It also has use in daily life for quickly sharing pictures and other small files privately and offline, for air-gapped systems and in airplanes. It's FOSS, a cross-platform app and CLI tool available now. https://codeberg.org/cukha/blastqr
