THE NSA JUST BROKE BITCOIN WITH QUANTUM COMPUTERS

SELL NOW ITS OVER

millions of mined coins from 2009-2010 are vulnerable including all of satoshi's

[Anonymous No.29834567]

no.

>quantum
the minute you read a piece of news containing this buzzword you know it comes out of the author's big hairy dirty asshole

The BTC implementation of SHA256 hasn't changed since 2009.

gummo mined 80k btc with 4 super computers he built, yet not many people know

the majority of coinbase transactions in 2009 and 2010 were p2pk, meaning that all mined coins from then have their full public key on the blockchain rather than a hash of the public key

coinbase was founded in 2012

>public key
>is public
>OH NOEZ!!!!!1

Back to /g/ with the other tards plz.

THE NSA HAS QUANTUM COMPUTERS

ECDSA IS BROKEN

NOOO they will mine all buttcorn NOOOOO.

[Anonymous No.29835549]

Fuck bros I just checked my wallet and all that’s left is an IOU note from the NSA and all my BTC is gone wtf

This. That swiss company that claimed to be able to crack AES with quantum computers was full of shit too, but the media still spewed it out. https://soatok.blog/2021/02/09/crackpot-cryptography-and-security-theater/ has a good explanation of why the things they said were rerarded.
Also, post-quantum cryptography will be standard long before anyone builds a quantum computer capable of doing anything useful - https://csrc.nist.gov/projects/post-quantum-cryptography/post-quantum-cryptography-standardization

memes aside, I don't understand what goes on in the mind of smoothbrains. They freak out about crypto whenever quantum computing is mentioned, despite quantum computing being a solved problem in crypto (fork, move to quantum resistant algorithm). And they don't worry about all the companies, hospitals, airports, local power infrastructure, water supply running on legacy systems with no clear upgrade path to anything quantum resistant

>Bitcoin and even other cryptocurrencies and their history are filled with examples of hardware and software changes that had to be made to make the network more secure and performant — and good security practices in the present (avoiding wallet reuse) can help prepare for a more uncertain future.
>So quantum computers being added to the mix won’t suddenly render classical modes of encryption useless or mining trivial — “quantum supremacy” now doesn’t mean that your encryption or the security of bitcoin is at risk right at this moment.
>The real threat is when quantum computers become many scales larger than they currently are — by which point planning for post-quantum encryption, which is already well on the way would come to the fore, and at which point bitcoin and other cryptocurrencies can soft fork — and use both decentralized governance and dynamism when needed in the face of new existential threats to defeat the threat of “quantum supremacy”.
