qBitcoin – Proposal for a decentralized online quantum cash system
- vadym909 9y agoI'll take it. It is going to 10x in a few months, right?
- ClassyJacket 9y agoWith those buzzwords in the name? Quantum AND blockchain? To the moon.
- Nition 9y agoHello. Could I interest you in Quantum Magnetic IoT Coin? It's got learning AI.
- ClassyJacket 9y agoBut does it have deep learning?
- Nition 9y agoOnly shallow unfortunately. It understands that Discworld is a comic fantasy series, but not that it's a social satire.
- sanityUnbounded 9y agoSeems like a decent paper, only a few typos. Let's run a 300 million ICO
- Frogolocalypse 9y agoWhy you underballing it? Two billion, min.
- ojr 9y agowhy not just start a penny stock like the Wolf of Wall Street, no blockchain needed
- Frogolocalypse 9y agoCuz they still have to be registered as a security in the US as a security.
- ojr 9y agobitcoin was made so that regulation couldn't interfere, bitcoin is a security as well in a global stock exchange
- Frogolocalypse 9y agoThe SEC doesn't actually regulate bitcoin. So that's not true, at least as far as the Securities and Exchange Commission (SEC) thinks.
- ojr 9y agodoes Ethereum/Bitcoin pass the Howey Test?
- throwaway29292 9y agoSorry, I want some tenuous connection to VR/AR as well.
- Nition 9y agoOf course. The blockchain can be viewed in VR as a 3D landscape similar to fsn file manager.[1] [1] https://en.wikipedia.org/wiki/Fsn_(file_manager)#/media/File:Fsn.png https://en.wikipedia.org/wiki/Fsn_(file_manager)#/media/File...
- arisAlexis 9y agoTheqrl.org check it out
- aligajani 9y agoThe hype is real.
- xasos 9y agoHow does this contribution differentiate from https://arxiv.org/abs/1604.01383 https://arxiv.org/abs/1604.01383? This work just seems way too early + applying quantum-safe crypto to existing Bitcoin ECDSA seems like an easier and more practical solution.
- sigmar 9y ago>Making a bock is time consuming and the system of qBitcoin is based on a quantum chain, instead of blocks A typo in the abstract makes it pretty unlikely that I'll read your proposal.
- Nition 9y agoYou can have many bocks for the price of a chicken but it can indeed be time consuming.
- IIAOPSW 9y agoI just want to clarify I didn't write this. Also give the guy a break. English isn't his first language (presumably)
- sigmar 9y agoMeant to add the 'your' as a way to generalize the statement. It's fine if English is not his first language, that's why you have others proof read before publishing. If there wasn't much effort to edit, I tend to presume there wasn't much effort put into it more generally.
- jianshi 9y agoyou're totally right...

- 0xbear 9y agoI feel like this would have better traction if it also used deep learning and were written in Go or Rust.
- toomim 9y agoWhat an exciting proposition— if you can use quantum teleportation to solve double-spending, then you don't need mining at all! You don't even need proof-of-stake.
- amluto 9y agoIt's unclear to me why one might want to use quantum blockchain-based money when there are reasonable proposals for blockchain-free quantum money, e.g. [1]. In any event, I didn't bother reading most of the qBitcoin paper because of things like this: > First of all, we need to consider how to transmit a coin made of quantum information. The best way, at the present, will be to employ quantum teleportation [2, 3], which succeeds in transforming quantum information to remote places. Great benefit to use the quantum teleportation is that the quantum information cannot remain the original place, in other words, it is impossible for a transmitter to keep the original quantum data once if the quantum information is sent. This is nonsense. It's like saying that you can transmit a file by mailing a USB stick, which absolutely guarantees that you, the sender, no longer have the original file. That's wrong -- all that mailing a USB stick guarantees is that you don't have the USB stick any more, not that you didn't keep a copy of the contents. Similarly, quantum teleportation eats the input state but says nothing about any other copies of the input state that may exist. [1] https://arxiv.org/abs/1004.5127 https://arxiv.org/abs/1004.5127 (disclaimer: I'm an author)
- IIAOPSW 9y agoI think the author was talking about the no cloning theorem. It is true. If you have a few qubits (representing money) and you don't know their state then you can't send the coin and retain a copy.
- deleted 9y ago[deleted]
- amluto 9y agoThat's only a little bit true. You need a much stricter condition to adequately describe "don't know the state". In any event, this has nothing to do with teleportation.
- cyphar 9y ago> That's wrong -- all that mailing a USB stick guarantees is that you don't have the USB stick any more, not that you didn't keep a copy of the contents. On paper, no-cloning theorem means you aren't able to make a copy of the contents. However, the obvious downside of this scheme is that it requires all coins to always remain as a qubit when stored -- otherwise you can re-generate the coin. Also you can't have more than one photon to contain said signal (maybe there's some coherence trick you can pull, but I've read several papers that have found that most quantum cryptography has been broken -- especially cryptography that depends on being able to detect measurement and no-cloning theorem). I'm generally skeptical of quantum cryptography when it depends on physical properties of qubits to provide its security, simply because previous research has shown that claims of security are broken very soon afterwards.

- zitterbewegung 9y agoIn theory quantum key distribution systems (AKA quantum cryptography) are unbreakable. In practice they aren't. See http://www.qudev.ethz.ch/content/QSIT15/Q_Cryptography_Q_Hacking.pdf http://www.qudev.ethz.ch/content/QSIT15/Q_Cryptography_Q_Hac... https://phys.org/news/2015-12-quantum-cryptography-vulnerable-hacking.html https://phys.org/news/2015-12-quantum-cryptography-vulnerabl... P.S. They describe a property where the money can't be cloned which seems to be further explored in this paper which the author has commented on this thread (see amluto). https://arxiv.org/pdf/1004.5127.pdf https://arxiv.org/pdf/1004.5127.pdf (Quantum Money from Knots) .
