edge 0 Posted July 6, 2017 (edited) With ever increasing achievements towards a fully usable quantum computer by so many nations, is there a plan in place to secure against quantum computers (if not done already)?@JoelKatz it would be great if you could give us your insights in this matter. Cheers! Edited July 6, 2017 by edge Share this post Link to post Share on other sites

JoelKatz 7,629 Posted July 6, 2017 Yes. Additional algorithms can easily be added, just as we added Ed25519. Existing accounts can be re-secured with a new key if desired. So you won't need a new ripple address. We haven't actually added any quantum-safe algorithms yet because none of the ones available today are perfect for our use case. And any algorithm we add we'll have to support forever. So we'd prefer to wait as long as we safely can so that we'll have the most information to make the choice of algorithm(s) to implement. 33 3 Xrpdude, CryptoJym, Xrphunter and 33 others reacted to this Share this post Link to post Share on other sites
Guest Posted July 6, 2017 Yeah I doubt there are any real quantum computers out yet, and even if they were I'd doubt they'd be able to run perfectly let alone send out an attack. Maybe in the next 5 - 10 years Share this post Link to post Share on other sites

BBS 137 Posted July 6, 2017 Dwave 2 is ahead in the game. How far do these need to go before they're a real problem? https://www.dwavesys.com/d-wave-two-system Geordie Rose - Quantum Computing: Artificial Intelligence Is Here: https://www.youtube.com/watch?v=PqN_2jDVbOU 1 Hodor reacted to this Share this post Link to post Share on other sites
Sukrim 1,345 Posted July 6, 2017 Dwave systems are great for quantum annealing (they are used for https://en.wikipedia.org/wiki/Adiabatic_quantum_computation), but not for crypto work. They are a special class of quantum computers, not the "general" type people are looking forward to. 3 BBS, Hodor and PhiGuy reacted to this Share this post Link to post Share on other sites

edge 0 Posted July 6, 2017 (edited) Thanks for all the replies. I'm still quite new to blockchain technologies. I was curious about this since I'm looking at Ripple/XRP and the rest of cryptos in long term. And yes, probably they are quite a few years away, but we will probably never know when the first one will become fully operational and in whose hands it will be, better safe than sorry. Same as with general purpose AI. Edited July 6, 2017 by edge Share this post Link to post Share on other sites

Few years ago it wasn't so essential for them to concentrate the project on crypto currencies. With this massive hype (perhaps earlier), no doubt they are looking into it.

Sorry, but I don't really get what you are trying to say. Do you suggest that adiabatic quantum computers are useful for attacking crypto primitives like ECDSA or SHA2 hashes? Or that there is even at least ongoing research in this area? If yes, I'm more than interested if you could link some papers. Share this post Link to post Share on other sites
tulo 2,852 Posted August 20, 2017 (edited) It seems a 2000 qbits quantum computer is available (but some are skeptical): https://www.dwavesys.com/press-releases/d-wave announces d-wave-2000q-quantum-computer-and-first-system-order Looking at the pace this is evolving I think in 2-3 years EVERYONE should implement post-quantum cryptography. Imagine quantum cumputers will be able to hack everything but XRP, it would be the new money of the world Edited August 20, 2017 by tulo Share this post Link to post Share on other sites
jargoman 256 Posted August 20, 2017 (edited) I bought some qrl - quantum resistant ledger. I figure even if ripple implements quantum safe algorithms who's to say there won't be a great culling of the 1000+ blockchains.
