If the bitcoin blockchain is based on Elliptic Curve Cryptography, and ECC is vulnerable to attacks by quantum computers, won't bitcoin be dead in only 10-20 years?

who cares, Im cashing out 50% before then anyway

It will, buy NEO.

They will simply change the cryptography to something quantum proof.

see this stupid question so often i cbf writng an answer. Just google 'bitcoin quantum'...

>> No.3319400

you can increase cryptography keys linearly while increasing the amount of qbits needed to crack the key exponentially

so they will literally just add bits to the keys and they will get that much harder to crack, assuming the quantum hardware is the bottleneck

if it's not, they'll just change the algo

But then its not really bitcoin anymore.

>> No.3319425

>>3319400
sorry, not the number of qbits but the amount of computational space required, which requires increasing the number of qbits

and increasing physical qbits is currently really difficult and you can null out a year's worth of (presumed) qbit hardware by adding even one bit of entropy. you cracked 256? cool good luck with 1028

>>3319409
literally doesn't matter what the algorithm is as long as the input performs the desired output

this is like saying bitcoin is no longer bitcoin because they patched bitcion

the result is still a ledger tracking the distribution of coins among wallets

No, the public addresses wouldn't reveal your private keys if that was used. So basically all they have to worry about is the trivial hardfork to quantum secure encryption.
