This is a clear shot across the bow of Dorsey's empire. Given Square's huge portion of their revenue coming from readers, things have to be looking bleak over there. Square is down 61% since October.

A lot of bubbly tech stocks are down massively, it's not particular to Square. The bubble popped. Teladoc is down 77% Fastly is down 77% Pinterest is down 71% DraftKings is down 70% Zoom is down 69% Palantir is down 66% DocuSign is down 62% DoorDash is down 61% Twilio is down 57% Twitter is down 55% Roblox is down 55% Etsy is down 54% DigitalOcean is down 53% Shopify is down 50% Cloudflare is down 50% Unity is down 4…

Man, I swear sometimes I feel like I’m on a forum full of wanted criminals, state actors, and/or felons. I’m not saying I’m against privacy. I am all for not being tracked, but we are approaching absurdity. I really want to see all of you who praise “privacy” go fully offline and use only cash. No cards. No bank account. Nothing. Salary? Cash, because earnings could also be sold and used for advertising. Groceries? C…

Earlier quoted context omitted.

I believe while the token is generated once, each transaction is signed with a unique signature (I believe that's the term) that only the payment processor can decipher. The merchant doesn't get any stable/identifiable information that can be used to track you across purchases/sessions/stores.

No, the merchant still does get a stable identifier with every payment (the "device account number"). More recently, an additional identifier uniquely identifying the underlying card has also been added [1]. That one persists even across multiple devices and token deletions.

Cash decentralises power to the extent possible. E-currency centralises it to an absurd degree. That's the point. The slope of convenience though is gradual and slippery indeed. Institutions we've had for centuries crumbling in a matter of decades is a matter of concern. They worked more or less. There is no guarantee what is replacing them will work but we seem to have blind faith they will, since we're throwing the…

Hacker News is such a bizarre place. On the one hand, we have threads about how browsers are fingerprintable and some app is using telemetry and endless discussions on theoretical zero-knowledge protocols and the importance of cryptography and Snowden saying this and that that get voted up to the top. On the other hand, something like this comes up which is basically another step along the "no-one accepts cash" funne…
