Thanks guys.

As I say Testnet debugging and stress testing has begun (status can be checked: https://theqrl.org/status/).

It is true we are recovering from a FUD attack by a former team member.

Additionally:
One of our community, Scott, built a faucet: http://testnet-faucet.qrlexplorer.info/
Our block explorer can be accessed @ http://qrlexplorer.info/

I would urge anyone interested to join the slack: http://slack.theqrl.org to join the our discussion (we have 1616 people in our #general channel).

Kindest regards,

[ANN] QRL : the Quantum Resistant Ledger project
by
inca
on 05/08/2017, 20:18:55 UTC
I would like to announce that the Quantum Resistant Ledger (QRL) has our launch window: mid-Q1 2018!

The QRL will be the first decentralized cryptocurrency which is implemented from the outset to be resistant to both classical and quantum computing attack. It uses a different system of cryptography to bitcoin (and all other altcoins) known as XMSS, which is a hash-based digital signature scheme, and therefore provably quantum-resistant.  The ledger will be the first to use quantum-resistant signatures on a blockchain, which provides an ultra secure store of value in the event of a sudden advance in quantum computing (rendering bitcoin, ethereum etc vulnerable to attack). The initial aim of the project is to establish a functional and secure blockchain on which more technology can be built, such as the Ephemeral post-quantum secure data channels.

The project has grown significantly over the course of 2017, led by myself, a core dev team, ancillary devs and a post-quantum cryptographer. We have added to that a marketing manager and small communications team.

We will ship with the following featureset in Q1 2018.
 
1. multi-platform qrlcore node release.
2. 100% PQ-secure address space for the QRL (XMSS)
3. cryptonight POW algorithm, 1 minute block-time interval, ability to mine in existing pools, using existing mining software.
4. ephemeral messaging layer capability (PQ-secure end-end data channel functionality utilising Kyber and Dilithium).
5. completely separated wallet and node functionality with all wallet-based requests passing through the node by our universal grpc api.
6. Use of slave XMSS tree signing capability to allow secure mining (and later in the year staking) keeping private keys offline.
7. GUI-based webwallet and full block explorer functionality
8. PQ-token capability out of the box — creating tokens on the QRL chain is now functional.
9. PQ-secure data stamping functionality out of the box.

We now have our first video "Introducing the Quantum Resistant Ledger" up on Youtube! Check it out - https://www.youtube.com/watch?v=Ck-sHNNYFlQ

Anyone who wishes to get involved can join our Discord server below. The best way to find out QRL related news would be to keep an eye on Twitter, Reddit, Medium, and/or Discord.

The QRL is currently trading as an ERC20 token on bittrex, upbit and liqui.

Genesis Block = 65M coins.
Final distribution in 200 years is 105M (exponential decay in emission).
Blocktime will initially be 60s.

When PoS Comes:
No minimum staking limit. Secure offline staking via deferred stake signatures. .

Feel free to ask any questions.
Many thanks,
Inca

Hi,

I'm the founder of the QRL.

I'm curious what exactly it is you are forking. I'm all about open source but we haven't opened our source code up with a public license yet - mainly because our python codebase is a POC and our first task is to code up a golang security grade version of the node and POS protocol post-seed funding round.

I don't have time to go through your project in detail but I would guard against trying to fork experimental code, especially unlicensed without asking permission.

So to elaborate, there's no way to test the resistance against anything quantum computing capable, due to technology not being there yet? So as of right now, this quantum resistance is theoretical if I read that correctly?

Not exactly. We already know what is susceptible: RSA, ECDSA etc. We know that the digital signature scheme backing bitcoin and ethereum etc are vulnerable.

There are several classes of 'quantum safe' signatures of which hash based signatures used in the QRL are the most promising.

Based upon existing mathematics if a sufficiently powerful quantum computer were created by a government then bitcoin (and everything else) would insecure but the QRL would not. But you are right that it is of course theoretical resistance because no such computer exists publicly to attack either chain and test out the hypothesis!

The idea with the QRL is to get crypto ready for this computer advance so we are ahead of the curve.

First, congrats for your initiative and work on QRL.

But Quantum Resistant Ledger can not be tested without a Quantum attack, even if you apply theory and mathematics, we are still far from Quantum computing and have no insight about its capabilities.



Thanks. But we do know already that Shor's Algorithm had been used to factor small numbers with early quantum computer prototypes. It is true we may be some way off from such machines breaking ECDSA - but the honest answer is we cannot be sure! Smiley

Update: I have begun implementing POS on the test node.

I'm not entirely knowledgeable with how you have achieved this, but will mining be any different then SHA-256 or Scrypt, X-11, etc.?

Whilst the current design has a placeholder sha-256 pow function the testnet release will be proof of stake. With this in mind I will circulate a proportion of the starting ledger balance at genesis.

Interesting you call it a ledger and not a cryptocurrency. Was that intentional? Is the purpose of the QRL more for tamper resistance recording of information then as a transfer/store of value?

Whilst my original intention was simply to integrate post-quantum signatures into a blockchain (which I have done successfully) I did envision the QRL as carrying value. Information can have value of course, but for a blockchain to work the base tokens must be desirable IMO.

It goes without saying that no matter how cool this is - one should never put a private key into a browser.

Whilst your intentions are probably well meaning - please no one actually use this site unless you are able to personally verify the source code.

Update:
I am pleased to report that XMSS is now successfully integrated into the test node. I have also created deterministic addresses within giant XMSS trees from a single recoverable hexSEED / 32 word mnemonic using a provably secure pseudo random number function (HMAC_DRBG).

The QRL test node currently supports 3 types of post-quantum transaction types: 1) Lamport-Diffie one time signatures below a many time merkle tree signature scheme (MSS), 2) Winternitz-OTS signatures with a many time MSS and now 3) XMSS - a recommended post-quantum signature scheme incorporating W-OTS+ and XMSS many time trees. I may remove the support for the first two and focus upon a single tx type with longer keys.

What is interesting is that the signatures with XMSS are roughly 12kb hexlified (~6kb binary). Internode compression of transmitted transactions and blocks may be something to look into as they are currently communicated as plaintext JSON. Creating an XMSS tree which can provide 4096 signatures/transactions safely generates a wallet file size of ~50mb! There are around 330,000 256 bit keys generated (bitmasks, secret/public key fragments etc) for just this single tree. I was perplexed by this as most people like quite a few addresses and this would generate absolutely huge wallet files. But I have discovered a neat way of generating hundreds of addresses within the XMSS tree by simply contracting the merkle tree and recalculating the root value+PK..and voila a new address. New addresses can be added with minimal additional calculation (just need to keep the tree differences) as they share bitmasks and OTS keys with the original.

Releases:
A collaborator has created a blockchain explorer for the QRL (testnet) and we will be making that public once it looks pretty enough Smiley - probably later this week.

Whilst I work on the node he is now working on a client side JS web wallet similar to mymonero which will communicate with a custom node via an API. The general idea is that user supplies a seed word mnemonic and the JS wallet obtains state information from the node. Transactions can be created client side and sent fully formed+signed to the node. It is only as secure as the browser but should suffice for less technical users.

Todo:
There is still plenty of work to be done. The next stage is to declutter some of the code, tidy up the protocol, simplify and better partition the state code, finally sort the currency units and improve reliability of the node - in particular the chain following behaviour.

PoS:
Recently I have had some ideas about implementing a Proof of stake system. I like the idea of using proof of stake in the longer term. I will experiment with introducing a PoS system for the QRL which is very simple but secure. I have been writing my ideas for a protocol in a second whitepaper which I will release after some testing!

More updates as they come..Volunteers welcome as always.

talking about the quantum computing attack with the foresight consciousness is necessary,im very interest in this. but i think webwallet is not  primary task but the testnet is

Yes I won't be developing anything more than the server side code for a webwallet - needs a JS developer although we could fairly easily code up a mymonero clone.

First priority is to complete the node.

The project is still seeking python developers who want to join up. Anyone interested in the benefits that go with joining a project this early PM me.

Happy new year and a profitable 2017 to you all.

This looks very interesting. I'll be watching closely.
Haven't read the white paper yet but other than using hash based signatures will this have any other implementations that will be different to BTC/ETH etc?

Actually the ledger addresses are derived from a modified merkle tree signature scheme (XMSS) in a hypertree construction using hash-based one-time signatures to sign transactions.

But you are correct that at this time the project is to be similar to BTC, featuring a capped upper supply limit, with very limited scripting and an emphasis upon security over scalability (the signatures / transactions are necessarily much bigger than any other crypto ledger thus far).

We are at quite an early stage so some design parameters may change but i am keen to allow bitcoin users to directly import their balances into the chain for a time after the main net goes live.

Thanks for the interest.

We need to be fair to the users, and let them know they have a choice. And provide them the tools they need to make their voice heard. Only then we can truly claim to be decentralized.

It's strange that you think most active Bitcoin users aren't aware of projects like Classic, XT, etc. Everyone has heard of them, and the block size issue has been argued to death, and yet most users continue to support Core's road map for scalability. Users have made their choice already.

Ah it's theymos' alt cobra to the rescue. 

Given you have been censoring discussion on any alternative clients who knows what most active bitcoin users are aware of. It is just electronic cash to most people. Still you have singlehandedly contributed to the decline of market share bitcoin holds within the ecosystem. Oh and lost any vestiges of credibility you ever held in the cryptocurrency space :-)

Longs pretty high at 41M on finex. Shorts extremely high at 23k. Market floating for a giant move. Toss a coin. Hope you are all hedged appropriately after the recent huge gains.

I personally think we have a few months for the market to get acclimatised to this new price point before we charge much higher. But hey this is bitcoin so it could be ATH next week.

EDIT: it is worth pointing out that the trolls talking down bitcoin on here are themselves long otherwise they would have left long ago..

I wonder how low this goes. Full retrace down to 450? or do we hold 4000 cny. Unfortunately cannot check the price too often so move my bids right down to the upper 4xx's though I don't really expect it to get anywhere near there.

Things are certainly a bit more bearish now.

I wonder where the bottom is..

I managed quite spectacularly to disappear 10 btc earlier by selling at the exact bottom and buying in higher. Time to sit this out for bit.

Oh man, I know how you feel.  Lost many btc in that head fake bear trap back in Nov.  But then made up for it by rebuying around 450.  I also just bought some more trying to catch this falling knife at 660.  We'll see if it holds.

My goal has always been to gain more btc over time, not reduce them.  That bear trap back in Nov really taught me something: when in doubt, do nothing (aka just Hodl).

Yes. Amazing how easy it is to trade away those gains by churning your account or mistiming entry and exits. Oh well.
