pretty crazy
Bonkers.
Seems so ridiculous once you've understood PKC.
Never thought about this 😬😬
And your social security number is the private key to yourself, according to the US, and it hardly has any entropy!
Kinda. But you can grovel before your custodian if someone sweeps you and they will waive the debt.
Yup, it’s a multisig setup where we only have 1 of an unknown amount of keys.
Damn, never thought of it this way
The exception is tap to pay, that basically works using a signature at the point of payment
Checks also have the private key to your checking account printed on every one just like credit cards.
Crazy thing is, inflation theft is still higher than checks and credit card fraud combined.
