You can sign transactions offline and hand deliver the file if you felt so inclined.
Signed transactions cant be modified.
Someone needs to make sure nodes see it that transaction and add it to the database, eventually.
This user experience has not been refined, but is very possible. A system with fewer nodes, like if the internet was attacked and not available, would still work for this currency.

- ggreer 6y agoIt's usually less than 300 bytes. A comically huge QR code could handle that.
- Canada 6y agoThe specific transaction this post refers to was 1813 bytes. It had 12 inputs that had to be signed for making it larger than average. For $10M I'd be willing to manually type out the 3626 hex digits, or if feeling lazy splurge on a $10 USB stick. Only 3 inputs account for almost all of the balance, so really it could have been moved for under 1000 bytes, which I happily write longhand on paper with a quill in triplicate before I'd even consider exposing the secret key to the internet.
- mianos 6y agoLike the Coldcard wallet where you can choose to only transfer the transaction via an air gap on a MicroSD.
