When you make online transactions sitting in a cafe you feel safe in sending websites your credit card. This admittedly requires _some_ optimism but it would be surprising if someone in that cafe could break TLS.
Systems like zcash and monero are similar: if you don't trust the cryptography then they're not useful, but it seems like a strange objection to say somebody could do unsavory things if they could break the cryptography, that's what it's for!
- shadowgovt 5y agoI think OP's claim is that even if someone breaks TLS, they only get the data from that cafe session. Finding an exploit in the not-yet-battle-hardened implementation of the cryptographic systems in popular blockchains could reveal private information that is recorded in a ledger "forever."
- can16358p 5y agoI don't think we need to break any cryptography here. Someone with enough ether can post private data or offense on blockchain already, and it'd be forever available to anyone.
- threeseed 5y agoI feel safe because my bank is responsible for that transaction. If the cafe, thief or anyone steals my money for whatever reason other than me physically giving someone my card/PIN then the bank or credit card company is legally responsible. And they will refund you the money. Look forward to Web3 without a similar safety net in place.

This admittedly requires _some_ optimism but it would be surprising if someone in that cafe could break TLS. The worry wouldn't be about someone breaking TLS, but someone MitM your connection with your card processor in a way you don't notice. One is much more likely than the other.
