Bitcoin for payments is the DUMBEST shit I have ever heard. It's not fast It's not stable It's not private You really want to wait 90 minutes for confirmation on a speculative asset?
If lightweight cryptography was a good idea, we’d just call it “cryptography.”
we'll all agree that 'smart contract' isnt a great name, inherited from naive cryptopunk utopia; what else?
privacy ayatollahs recycling the positivist gimmick from Isidore Marie Auguste François Xavier Comte (and now Brazil and many others)

This will be your life if you commit crimes on the internet. Cyber crime is bad and illegal
I just sent money to a friend, with.. - instantaneous settlement (<10 seconds) - privacy of amount, sender, recipient, even transaction existence - reversible transaction in case of an error in the address/payee - 24/7 transaction support - only 5CHF gas fee

There's an old joke that all of cryptocurrency is the process of rediscovering the reason everything in finance exists by trial-and-error and it seems to keep playing out.
blockchain folks recently rediscovered "TEEs" wait until they rediscover the concepts of.. - role-based access control - security zones - secure boot - revocation - AAA
Most Bitcoiners don’t consider #Zcash until after a privacy failure, just like people who only start wearing seatbelts after a crash.

Since someone asked: a confidential token transfer in FHE costs around 400k gas. Thats only 10c on Ethereum mainnet and a 0.3c on Base. FHE is cheap guys
Making a confidential token transfer with FHE: # Send amount if enough balance, 0 otherwise has_enough_balance = FHE.ge(balance[from], amount) amount_to_send = FHE.select(has_enough_balance, amount, 0) # Send the money balance[to] =…
Fun historical story that most people don’t know: when the US National Institutes of Standards and Technology selected Keccak to be the new Secure Hash Algorithm (SHA3), they knew that it was inefficient—that it did a lot computation that wasn’t necessary for security. ⤵️
Easily one of the best paragraphs every in a science textbook
