Physical bitcoin, can be transacted offline. Just hand it over like a dollar bill:
https://opendime.com https://opendime.com
Still mostly useful for larger amounts, though, due to the relative high cost of hardware, but it's new.
- icebraining 9y agoI seem to remember a simpler version - it was a scratch card, which had the address fully visible (so you could check the balance was correct) but the private key hidden behind the scratching area. That way you could reuse the bill or scratch it and transfer the amount. Can't seem to find it again, though.
- px1999 9y agoHow would you be able to tell what the balance on the stick is without power? How would you be able to calculate the current value in fiat, if you had power but no internet? For that matter, how could you verify that someone hadn't transferred the balance in a transaction that didn't exist in your (now offline) ledger (if they had internet and you didn't)? At some point, if you're being practical rather than ideological, isnt cash the clear winner in these situations? YMMV if your currency isn't as stable as USD though
