The quantum fud is overblown, imo. The same people who fud it as an excuse not to have Bitcoin, are the same people who don't realize nukes, their stocks and bank accounts would be easier to compromise lol.
Yeah, that's why I'm not really worried about it. Seems like an easy defense.
I didn't even notice that, how they didn't bring up quantum.
When he made the comment about Satoshi having sent a transaction, being where vulnerability is, I knew of this quantum thing, so that's what I assumed he was talking about.

They talk about how Satoshi’s coins “will eventually move” because how the keys were generated at the time was a less secure process. And when Satoshi sent the transaction to Hal, he “put a piece of information in there that people could use…”?
How correct is all that?
From GPT:
The ability of quantum computing to potentially crack a Bitcoin private key is tied to how public keys are exposed during Bitcoin transactions. Here's how this works:
Public Key Exposure in Bitcoin Transactions
Receiving Bitcoin: When someone receives Bitcoin to their wallet, only the Bitcoin address is exposed. This address is derived from a hash of the public key, specifically through SHA-256 followed by RIPEMD-160. Hash functions are resistant to quantum attacks with current quantum algorithms, making it computationally infeasible for a quantum computer to reverse-engineer the public key or private key from the address.
Sending Bitcoin: When a transaction is made to send Bitcoin, the public key is included in the transaction for verification purposes. This exposure of the public key is critical because it opens up the possibility for a quantum computer to attempt to derive the private key.
Quantum Computing and Cryptographic Vulnerabilities
Bitcoin's security relies on the elliptic curve digital signature algorithm (ECDSA). ECDSA is secure against classical computers but vulnerable to quantum computers due to Shor's algorithm.
Shor's Algorithm: A sufficiently powerful quantum computer can efficiently solve the discrete logarithm problem, which underpins the security of ECDSA. If the public key is exposed, Shor's algorithm can calculate the corresponding private key.
Why Sending Bitcoin Makes Keys Vulnerable
1. Exposing the Public Key: When Bitcoin is sent, the public key is revealed in the transaction data.
2. Quantum Attack Feasibility: With the public key exposed, a quantum computer can attempt to use Shor's algorithm to calculate the private key.
3. Time Sensitivity: For the quantum attack to succeed, it must be executed quickly, ideally before the transaction is confirmed and miners move the Bitcoin to a new address.
Why Only Receiving Bitcoin is Safer
If the Bitcoin is only received and never spent, the public key remains hidden. Since quantum computers cannot reverse the hash functions (SHA-256 and RIPEMD-160) efficiently, the private key cannot be derived from the Bitcoin address alone.
Key Takeaway
Bitcoin's vulnerability to quantum attacks lies in the exposure of public keys during transactions. By not sending Bitcoin, the public key remains hidden, preserving the security of the private key against quantum computing attacks.
Excuse me sir, hate speech is not a good way to increase the vibes
If burgers are made of beef, why are they called ham-burger? 🤔
I bet it'll be one stroke per guy 😂
I can't believe they didn't call off the second goal for Toronto.

The shecession was tackled, but now we have to get the good vibes going.
Oh yeah, we went from a shecession to a vibecession. Things have never been worse here.
I'm not sure, honestly... They may just like the idea of being fucked on a pedestal, instead of the floor 😂
We didn't have a bed frame for years, and it drove my wife crazy. I'm weird with furniture, where I won't buy something, until I find the exact thing I want. Took a few years, then I finally found a frame I liked at a price I was willing to pay. Haven't regretted it. It makes our bedroom look nice.
Mine seem to be okay at the moment. There are times when relays are down, and I lose some people temporarily.
Yeah, I agree. I think his content is still good, but you can feel there's a difference in his delivery.
BTC is the perfect bridge between people who want to eat real food,
and people who raise real food...
We often hear about the health benefits of beef, but what are your thoughts on pork, chicken & fish?
