Title: [QRCoin] - QauntumResistantCoin - the first alt resistant to quantum computers Post by: ripper234 on September 30, 2013, 09:34:40 AM Edit - rename from
There is ongoing research about building scalable quantum computers (in fact, I just met someone at the Bitcoin Europe conference who claims to have made real progress (http://noospheer.wordpress.com/2013/09/04/why-turing-machines-are-quantum/) in this direction). Regardless of any specific implementation, perhaps it is about time we start designing QuantumResistantCoin - the first Bitcoin fork that will be designed using Quantum Computing resistant algorithms. I am interested to find partners that would help me launch such a coin (disclaimer - I have negative amounts of free time, so such partners will be doing most of the grunt work :)).

Registered qrcoin.org.

1- Quantum computing era is not just about quantum hardware, it may become viable to see a lot of new quantum algorithms that may work much more effective in breaking cryptos than what hypothetically exist now, so a bit more reliance on academic work before designing anything is advisable. 2- Up to point 1 and the fact that it will take a lot more serious work than a routine coding project, it is much wiser to look after more effective way of designing the hashing-node network topology (51% attack) and also more stable economic model (better supply-demand difficulty adjustment and POS) Title: Re: [QRCoin] - QauntumResistantCoin - the first alt resistant to quantum computers Post by: miffman on October 02, 2013, 08:22:54 PM this will only be needed once quantum computers are actually commercialized and is accessible to the general population

By the time Quantum Computers are available... Bitcoin PoW hashing will be an anachronsim.

I agree that we will need to gather up the best of breed academic work about how to build quantum-resistant algorithms. I wouldn't put any proof of stake algorithms in this ... KISS. Let's make a simple coin with just one major parameter changed - the hashing algorithm (we can also do faster confirms like Litecoin ... why not). Adding POS just complicates things. The next coins after QRCoin can add other features like POS. |
