A quantum computer just "broke" Bitcoin. Except it didn't. Not even close.
Google Quantum AI published a paper showing they've cut the theoretical ECDSA attack down to 1,200 logical qubits. They didn't publish the circuits. They didn't run the attack. They published a zero-knowledge proof that their math works, then cited national security.
Here's where we actually are.
Entangled logical qubits achieved so far: 96
Coherence time: 1-2 seconds
Time the attack requires: days
Physical qubits needed: 500,000
Largest quantum computer today: 1,200 noisy, non-error-corrected qubits
That's a 100,000x coherence gap. It's not a software problem. It's a fundamental engineering problem that nobody has solved.
But here's what most people miss.
Bitcoin developers aren't waiting for a crisis. They're already shipping.
SHRIMPS: post-quantum signatures 3x smaller than NIST standards, built for Bitcoin's block space constraints.
BIP-360: a quantum-resistant output type already live on testnet, with BTQ Technologies running transactions through it.
The full upgrade could take 7 years. That's why the work started now.
The protocol will be ready before the computers are.

Onko sinun palkkasi noussut 250% viidessä vuodessa, eli noin 20% vuodessa?
Jos palkkasi oli 3000€/kk vyonna 2019, onko se nyt 7500€? Jos ei ole niin minkä arvelet syyksi?
Huom! Laskelma olettaa että työpanoksesi on pysynyt samana.
@anttiviljami Probably once humanity realizes that something that comes out of evolution must be adapted to instead of trying to destroy it. You have cancer every day but your body is attuned to get rid of it. Cancer evolves against these measures and wins.

We prototype a Search Engine similar to Haskell's Hoogle but for C. You roughly describe the signature of the function you want and it gives the list of function closely matching the description. Planning to turn it into something I can use daily.
The new Paypal USD stablecoin has an "assetProtection" role which can wipe your balance in two transactions (first `freeze`, then `wipeFrozenAddress`)
In smart contract security we call this a "centralisation attack vector"
@stskeeps I've only lately realized that in order for NFT's to make more sense on Eth they should have shared common cryptographic parameters, so that the keys in IPFS and Eth would correspond properly. Now its a bit of a mess to try and verify hash ownership on IPFS.
A very dark experiment is under way in Nigeria, with deadly consequences. Since October 2021, 99.5% of Nigerians have refused to use the central bank's digital currency, the so-called e-Naira, preferring to continue using cash. So what did the central bank do? It doubled down.
🤯 Full body tracking now possible using only WiFi signals
A deep neural network maps the phase and amplitude of WiFi signals to UV coordinates within 24 human regions
The model can estimate the dense pose of multiple subjects by utilizing WiFi signals as the only input
