Elliptic curve
https://en.wikipedia.org/wiki/Elliptic_curve
The curve is used for "digital signatures".
Alice will be sending a message to Bob. Alice digitally signs her message, then sends the message and the signature to Bob. Bob is able to know that (1) the message really came from Alice, (2) nothing was added/removed/changed in the message between Alice and Bob.
This is important for Bitcoin.
When Bob sends Bitcoin to Alice, his wallet digitally signs, then broadcasts the transaction to all of the Bitcoin nodes, saying, "Owner of address 'B' sends 0.75 BTC to address 'A'." Digital signatures allow the other nodes to know (1) that message was actually sent by the owner of address 'B', and (2) the message has not been altered in any way.

They're mentioned many times because it's the first public ledger, very similar to how #Bitcoin works. The coin isn't moving, just the ownership changes - the stones worked the same way.

#Bitcoin changes you
Today's #Bitcoin test:
#Bitcoin
#BTC was never meant to be a unit, even the code is working in sats as units since the beginning.
Very true. We somehow messed it up, making it hard to go back.
Bits made sense, few years ago. Not anymore, IMHO
Controversial take: #sats > #bits because you have moar units 🤔
Seriously, using bits alongside sats makes things more complicated. Like when we had this in the UK:
Pounds
Shillings
Pennies
#Bitcoin doesn't want to go there! http://projectbritain.com/moneyold.htm
If something ain't #opensource, it's pushed by the pre #Bitcoin corporation minds.
Still have one more year until every #EU #Bitcoin Pleb gets hit by the regs.
