If/when quantum computers are able to break ECC in real time (before the transaction is committed to the blockchain) that will be a real problem.

I believe for BTC the public key is vulnerable as soon as the adress has been used once. So for a BTC address to be safe for quantum attack, it has to be unused. Ever.
The public key is not exposed when bitcoin is deposited in an address - an address from which nothing has been spent is secure. The danger is in spending twice from the same address - the public key is exposed when you spend the first time, and the attacker has much time to try to derive the private key. Address reuse is already considered very bad practice for this reason. So it just isn't so that every address in the blockchain is vulnerable to quantum computers. Just those that have already exposed their public key. |

But the bitcoin blockchain does not store the actual public key - it stores a hash of the public key, and going from that to the actual public key is close to impossible, even for a quantum computer.
The real public key is exposed during a transaction. This is the vulnerable point.
Or so I understand it.

An overlooked point: this will be a cash settled market ( http://www.zerohedge.com/news/2017-10-31/cme-launch-bitcoin-futures-q4). No bitcoin will actually change hands. If you want actual bitcoin, you have to cash out of your futures contract and buy bitcoin just as you otherwise would. If you want to short bitcoin, you don't actually have to borrow a bitcoin, you just have to put up the required cash margin. Or so I read it. I think on most other futures markets you at least have the option to settle in the commodity traded, e.g. you can demand real gold or real pork bellies on those markets, though hardly anyone does. This will have consequences, but I'm not smart enough to know what they will be. It creates an exclusively paper bitcoin market that will operate in parallel with the real bitcoin market, but the prices on the paper market will be set according to the "CME CF Bitcoin Reference Rate (BRR)" which is supposed to be an agglomeration of rates from various "constituent exchanges" which are Bitstamp, GDAX, itBit and Kraken - all trading in real bitcoin. In a "real" futures market, if you shorted bitcoin you would have to borrow bitcoin and sell it, expecting to buy it back at a lower price, and this would push the price down. But in the CME version, no bitcoin would actually be sold on the real exchanges, so the downward pressure on the price would not be direct - and the effect on the CME prices would not be direct either, since the CME prices are fixed by the "real" prices. My head hurts. This is as far as I can go. |

Hi guys, new to Curecoin and not an investor (yet, anyway). I was very surprised to learn that Curecoin has a quantum resistant algorithm and has had it for some time. Are you aware that hardly anyone knows this? Nobody on the QRL (Quantum Resistant Ledger) discussion on Discord had any idea. They think IOTA is the only other game in town. This could be huge for you - if anyone knew about it.
Of course protein folding is one of the things that quantum computers would be great at. Could a quantum computer mine Curecoin? If it could, obviously Curecoin would need quantum resistance to keep its blockchain safe. There has to be a tie-in here.

I don't really understand the "platform" features. The whitepaper is badly out of date on some issues (including the initial distribution discussed above - the distribution by Bitcoin swap is "inoperative"). They say they will have it updated soon. For more up-to-date information see the blog at https://medium.com/the-quantum-resistant-ledger. |

Here's the QRL thread: https://bitcointalk.org/index.php?topic=1730273.600This post from that thread might answer some questions: Quantum resistant blockchain is a good idea but their is already many project working on it and usually it is just a security feature of the project and not them main feature. Your coin should bring something else or you should better put your effort to help some already working poject with your competences in quantum resistant blockchain.
This project is A LOT more than simply quantum resistance. I quote for you couple of my earlier posts in this thread to save time and they also explain why implementing real quantum resistance on existing chains is a no go. Look how many years it has taken and still debate is ongoing about BTC scaling it's a nightmare to implement anything on existing chains. I still dont get it what QRL makes unique. There are already quantum resistant coins out there and it seems to be no big problem to integrate quantum resistant mechanism in existing coins in the future. So can anyone explain me what QRL makes special? I really dont understand it but i want  No there is no quantum resistant crypto out there other than IOTA, but IOTA is a DAG (+ last time I checked the consensus in IOTA is centralized it's not even decentralized). I know there have been a few cryptos to make this claim because they use really long keys or whatever, but they still use Elliptic-curve cryptography. Quantum computer can use shor's algorithm to break this kind of cryptography which is used basicly in all crypto's today. Yes it is a big problem to integrate real quantum resistance or they would have done it already and most of them don't even have any plans to do it. Ethereum is saying they will do it, but the way Vitalik is saying now that they plan to do it is to implement one time keys scheme and it will be optional. One time key scheme will simply not be enough it's more like a marketing stunt and Vitalik can't implement any real quantum resistant solution because that would bottleneck he's already struggling network. He wants the network to scale or the idea of Ethereum dies and what is even worse is that it will be optional that leaves a lot of addresses compromised and will be devastating in a post QC event. What is unique in QRL you ask? 1) Use of stateful XMSS signatures to secure addresses. 2) Custom hash-based POS algorithm generating randomness using hash-based PRF and iterative keyed hash-chains. 3) Ephemeral messaging layer with anonymous completely private post-quantum secure end-end data channels. I would also add that the team is unique. They even have a post-quantum cryptography researcher in the team (which there are only a few in the whole World) who is also working on a post-quantum protection project funded by the European Commission. The lead dev is really a genius and most friendly person I have met in crypto and they are not greedy. They could have have collected 10's or 100's of millions for this project like many others have done, but they capped crowdfund at 4M$ because anything more would just be greed. They really believe in their vision and that this is important for the World. Rest of the team is just as awesome they have really delivered these past months. You can see this on Github and if you join the alpha testers. As some wise man once said. Invest in people, not ideas. Below is also the roadmap for features to be implemented after mainnet launch. https://theqrl.org/roadmap.htmlNatively quantum resistant ledger is the perfect platform to build on. |

What would be the process of an ERC-20 token "swapping" for a QRL? Would the ERC-20 tokens somehow cease to exist? Is that possible? How would the QRL blockchain be able to use the private keys from the ERC-20 token, since the protocol would have to be different?
There will be means to burn one's ERC20 tokens in exchange for mainnet tokens. Beyond that, I don't know the details. Such an exchange is far from unprecedented though. |

Sounds like a scam to me. 1:1 swap with bitcoin?? BTC is now trading > $5500 and a QRL is at 0.70. Besides, the circulation of QRL ~100,000,000, not 21 million.
Nice catch  QRL is an ERC20 token right now but will move to its own blockchain hopefully in about 3 months (but who knows about these things). At that time the ERC20 tokens will be swapped for QRLs on their own blockchain. Somebody had a brief mental lapse there - of course there's no swap with Bitcoin. QRL is probably actually a decent coin. It solves a genuine problem to which most coins are vulnerable. I have done my research and I am impressed by the development team. Contrary to what might be implied by the OP, they are not rolling their own cryptography but are using established techniques. This coin is designed from the ground up to be quantum resistant, it's not just an add-on. There has been a flood of articles in the past six months about advances in quantum cryptography. Google supposedly has a 39 qbit machine nearing completion. Google "quantum chip" if you want to see how fast things are moving. Interestingly, I think Curecoin was the first with a quantum resistant algorithm. It's been out for a year or two already. Curecoin does protein folding calculations for medical research for its POW algorithm, which is one of the primary applications for a quantum computer. There must be a connection there somewhere. Disclaimer - not surprisingly, I have a position in QRL. No position in Curecoin. |

And why only 42 coins. Whence such figure. For example, I like the figure 100. A wider market coverage. True, the more coins, the harder it is to monitor them. It is necessary to build a whole system of signals and monitor them. But, I think that 25 percent of the capial should be kept in the etherium, and 25 percent in bitcoins.
It is a reference to Douglas Adams "Hitchhiker's Guide to the Galaxy" in which 42 is the answer to the ultimate question of the universe. Unfortunately nobody knows what the question is. |

maybe some new coins with valuable technology,such as deeponion.I think it has great potential.
Yes, you are looking for a coin with unique, even game-changing technology that sets it apart from the hundreds of wannabe coins out there. My money is on QRL which is designed to be secure against quantum computing which is advancing far more rapidly than most people realize and which has the potential to break RSA and elliptic curve cryptography used in almost all cryptocurrencies. |

Probably your previous failed transaction is still sitting in your daemon's tx pool which causes the daemon to think you're trying to double spend your coins. Do "flush_txpool" in monerod and try again, now the "double spend" error should go away.
Thanks! All is well now. |

Another "withdrawal in limbo" problem here. We're a nonprofit that received a gift of cryptocurrency and registered on Kraken in order to liquidate it. We eventually got Tier 4 status.
We made, fortunately, only a small test sale and attempted to withdraw the proceeds to our bank. That was 28 days ago. The withdrawal is still listed as "pending" on Kraken. We submitted a ticket #647966 and heard that the problem was with SynapsePay and have attempted to contact them but haven't heard boo from them or, again, from Kraken on repeated attempts.
If Kraken is sending our money out into limbo and deciding after that it's not their problem, there is something seriously wrong here! If we could at least get the money into our Kraken account again we could buy Bitcoin and get it out that way.
Hi, this ticket has been escalated up a level. We want to make sure this problem is solved. Thank you for bringing it to our attention, and don't hesitate to contact us again if the problem continues to occur. It is now 43 days since we submitted our withdrawal, 14 days since our ticket was "escalated", and the withdrawal is still pending. We have heard nothing from Kraken, SynapsePay, or anyone else. Now 44 days in limbo, 15 days since the promise to escalate. Still not a peep from Kraken. |

I have a problem here -- I tried to send a large amount of Monero from my GUI wallet to Bittrex. The Monero never arrived and I see that the GUI wallet still has "Block height: PENDING" after 6 hours.
So, following advice I found via Google, I deleted all my wallet files except the .keys file and reopened the wallet. As expected, it scanned the blockchain (doesn't take nearly as long as with the prior version, is this expected?). Voila, all my Monero are back in the wallet and the pending transaction isn't there.
So I tried to resend the transaction to Bittrex and the transaction fails with the error message "double spend".
Any idea what is going on here? Thanks!

I'm putting this in a separate post because I am writing now in my private capacity as a Kraken customer.
I got myself verified at tier 4 and, naively, assumed that all would be smooth sailing. Until I discovered that fiat withdrawals didn't work. Tried that on Sept. 1 and the wire transfer failed without explanation. Submitted a ticket, have lost track of escalations etc. Finally on Oct 4 I received a reply that my documents have been reviewed and withdrawals should now work.
Apparently there is a whole extra layer of verifications that one has to go through after one is approved at tier 4 if one wants to actually withdraw cash, which is the reason I chose Kraken in the first place. Don't you think that it is a little disingenuous to tell someone he's approved at tier 4 and can withdraw $500,000/month and not tell him that, well, actually, he can't expect withdrawals to work? Don't you think that Kraken should notice that it should be working but isn't? Why is it necessary to even submit a ticket in this case - shouldn't Kraken notice that their tier 4 customer is having problems and start working on the problem on its own?
Oh, and in the middle of all this my login stops working with no explanation from Kraken. Had to open a ticket, resubmit all my identifying information and wait a week. Then I get a message that it's working again with the same password.Why didn't Kraken take the initiative and notify me that there was some problem? If my account was re-enabled with the same password Kraken couldn't have thought my account had been compromised. Why did this happen at all?
Maybe fiat withdrawals are working for me now. I will never know. I have converted my cash account balance to Bitcoin and sent it to an exchange that actually works. At least crypto withdrawals are working, thank you very much.
This thread is a litany of horror stories from Kraken customers and empty promises from Kraken. It is only a matter of time until someone starts a thread on the main bitcoin forum entitled "Kraken: it's deja vu all over again" or "Post your Kraken horror story here" or "Poll: has anyone actually succeeded in getting money out of Kraken".

Why we are going nowhere?
We may well go nowhere for many months, until the meme of the vulnerability of almost all cryptocurrencies to quantum computing begins to take hold. Until then we're just another wannabe cryptocurrency with a gimmick nobody takes seriously. It will happen. |
