Jesus Gyrsur. I want to see the real version Shocked

That's some next level figure there.

you trust the protocol which you verify with your own device which implements BIP 174. the other party signs the tx offline with his device and exchange a SD card with you. you verify the tx offline with your devices and after this you hands over the Cocaine. Wink

I just cant wrap my head around what prevents the hillbilly from spending that input that he used in his offline transaction with me on the block-chain before I can get home and publish the transaction myself. Huh

Really I need to actually read the whole BIP myself and stop being lazy. Was just kinda hoping someone here would have a quick answer that would bail me out of all of that work. Cheesy

maybe a collision if you upload the tx and he doesn't do that which prevents him to use the BTC a second time? have to read it too.

EDIT: but then you have to be fast! interesting! must study it! Grin

Got it. The Cocaine buyer have to sign the BIP 174 tx with the amount and have to upload it at home. then he and you will meet in the wilderness. you get the sd card with the proposed tx but it's not final until you sign (and check) it offline with your own device. than you can hand over the Cocaine. And if you're lucky you will get a bullet too. Grin

EDIT: the difference too exchange a pure private key is you have not to wait for at least one confirmation if you transfer the amount away from the private key from the buyer. you check and sign the proposed tx OFFLINE and the coins are yours. that's it! maybe a currently OFFLINE mobile wallet with BIP 174 support can scan a QR code from the buyer without exchanging a SD card.

EDIT2: can't resist! Grin
