Google Quantum supremacy -Do you think that's the cause?

According to that leak they will be able to rewrite whole bloackchain in seconds in max 2 years.

Did anyone managed to download the paper while it was online?

I think the consensus is that nobody really knows.
In which case the sensible thing to do is plan for the worst hope for the best.

I dont think Quantum computing is that much of a threat to Bitcoin because there are nodes and it cant write every single node at once.
It doesnt matter if it can rewrite the whole blockchain because its all p2p
It might mean though that bitcoin will be mined out really quickly. Which could increase the price of bitcoin.
But it might be safe to put everything into an alt coin that can't be mined, such as Tron.

They need 2300 qubit for that they are at 72 now and the more they add the more unstable it is, we are at 15 years of that minimum.

It's not because the same encryption that holds crypto together holds the fabric of the whole world together at this point. Government encryption, banking encryption, world markets, etc, etc. If someone had a supercomputer they would just break a few wallets and slowly sell the coins to fund bigger projects to kill the world.

I'm guessing he's just talking about a wallet that has bitcoin in it. Because that's all you can do with this. Each address (wallet) has a 256-bit password (32 characters). You could theoretically break that password with a quantum computer where you can't with a normal one. But that's all you can do, and it's still pretty far off, although china will probably be there in 5 years.

they wouldn't rewrite the blockchain, that's not possible [directly]. They would hack satoshi's key in a few minutes and steal the money.

there's no proof of the 53 bit computation, no details around the specifics (could be a nothing burger, even at '53-qubit') and is exponentially less difficult than a 256 qubit. But even with the facts its probably still a good idea for crypto to be integrating quantum resistant algorithms into their hash functions.

uncertainty will proliferate until someone releases more info. TA was already showing price action coming, but people will blame it on this news anyway.

What >>15703788 is saying is that only wallets that have their public keys exposed are the ones that can be cracked by quantum computers.

When you have not yet spent coins from an address, the public key of that address is not yet known, as the address is only a hash of the actual public key (which is somewhat quantum-proof, as a quantum computer can compute the private key from a public key, and NOT from a hash).

The public key is only revealed when you spend from an address.

What he and >>15703838 are missing though, is that old transactions are on P2PK, which exposed the public keys of these old wallets.

Afaik these include the "Patoshi" coins, which are over a million bitcoins, as well as other huge forgotten wallets of early adopters. These are all quantum vulnerable coins that can be dumped on the market if cracked.

You guys just don’t get it
There is now no cap on the amount of computations we can do by siphoning off the task to other worlds and if the theory of tech is correct it means the speed will double every two years but that’s with old tech we just leap frogged by leaps and bounds so the two year double algorithm could be every two weeks for all we know it’s THAT much faster.

So the next question is so what it can calculate numbers so fast that what use to take 3 days can now be done in one second. And that’s only the beginning.

It’s like we started walking at 3mph
Then we got a bike so 10mph
Then a horse 15-25mph
Then a car up to 300 mph
Then a plane we broke the speed of sound

Now to put this in computing capability we went from walking too mach 1 million.

And this is just computing numbers..... this is how regular computing started first it was numbers then it became rendering video graphics then it became entire neural networks for artificial intelligence.
So imagine offsetting all this to another dimension w no cap no limit we are LIMITLESS

What can we compute ? Anything
What can we render graphically ? Anything
What can we create ? Whatever we want

This is prob the start of that singularity we keep hearing about

>they wouldn't rewrite the blockchain
obviously quantum computing is much more dangerous for public key crpytography but it requires enormous big quantum computers.
> finding some data which hashes to a specific SHA-256 hash requires 2^256 basic operations on a traditional computer, but 2^128 basic quantum operations that is basically a lot faster but still impossibly slow. and if you factor in parallelization and energy consumption quantum computers will not hold a candle beside asics for a very very long time.
what is worrying is the 128^3 time a private key can be cracked from a public key (if known) which makes address reuse extremely stupid in the quantum age. no client does it by default tho.

[Anonymous No.15705394]

You will not be able to “rewrite the entire blockchain”. What it does is you give it a public address and set up the qbits so they collapse into the only possible value that can generate the public address,the private addrrsss.

this is kinda desirable if it happens slowly and gradually. no bitcoin should be lost forever especially not large amounts like millions.
a p2sh soft fork can lead to quantum proof public keys and with segwit the size of them is not a big concern anymore either.

[Anonymous No.15705563]

here is however something important to note... lot of people use deterministic hierarchic wallets. generated from a seed also used in hardware wallets. these will all be extremely vulnerable to quantum computers if breaking public keys becomes a thing. if you break any private key of a hierarchy it can easily generate all others. so in this case not reusing addresses is simply not enough precaution.

Why? If I was an insider at Google, and they eventually secretly made something with enough qubits to crack ECDSA, I would sneak in at night and send all P2PK UTXOs to 1BitcoinEater (maybe keep 20k Satoshi coins for myself).

And maybe even any UTXOs in reused addresses that have 4 digits of coins or more, and have not moved in 3 years or more.

Unless you can convince me how this is a bad thing.
