About VeriBlock
VeriBlock serves as the world's first blockchain which allows every blockchain in the world to inherit the full Proof-of-Work security of Bitcoin in a completely decentralized, trustless, transparent, and permissionless (or "DTTP") manner. The VeriBlock blockchain is built 100% from scratch, and has been engineered from the ground up to provide the most cost-effective, secure, and easy-to-use way for the world's blockchains to enjoy the unparalleled immutability of Bitcoin itself.


About Proof-of-Proof (PoP)
Proof-of-Proof is a novel consensus protocol invented by VeriBlock, Inc. which allows any blockchain (including sidechains and permissioned ledgers) to inherit the full security of Bitcoin in a truly decentralized, trustless, transparent, and permissionless (or "DTTP") manner.

It does so by gamifying the publication of data representing a blockchain's present state to Bitcoin (directly or indirectly) such that any user can participate and receive compensation for enabling blockchains to inherit Bitcoin's security. If you'd like to dive into the technical details, please check out our whitepaper.


DTTP
DTTP stands for Decentralized, Trustless, Transparent, and Permissionless; the core attributes which allow Bitcoin to achieve true security. We designed the VeriBlock blockchain and the Proof-of-Proof protocol with strict adherence to the properties which made Bitcoin what it is today, and believe that for any blockchain to truly inherit Bitcoin's security, it must do so in the same manner.


How is VeriBlock Mined?
The VeriBlock blockchain is mined in two different ways: PoW and PoP mining. PoW miners are responsible for creating the blocks, providing the blockchain with intermediate consensus, and providing blockchains inheriting security through VeriBlock with a PoW-powered first line of defense.

PoP miners are responsible for publishing a representation of the current state of the VeriBlock blockchain (and by proxy, all blockchains secured by VeriBlock) to Bitcoin in a fully DTTP manner.


How does VeriBlock Help Blockchains?
The use of Proof-of-Proof through the VeriBlock ecosystem enables any blockchain to inherit the consensus security of Bitcoin in a way which makes consensus attacks (rewriting agreed-upon history to perform attacks like double-spends) far harder to execute. This additional security significantly increases trust, allowing the blockchain's token to be listed on more exchanges, reduce confirmation waiting times for existing exchanges, and participate in fiat markets, due to the drastically reduced risk of consensus-related token theft. Consumers now have more confidence in the blockchain, and the project's developers can focus on creating a rich feature profile rather than inventing and implementing exotic and untested security mechanisms.


How does VeriBlock Help Exchanges and Merchants?
Due to the proliferation of secure blockchains, exchanges and merchants can list coins from more blockchains while generally requiring fewer confirmations, due to their dramatically reduced risk of double-spends.


How does VeriBlock Help Bitcoin?
PoP miners securing the VeriBlock blockchain spend Bitcoin to publish information regarding VeriBlock's present state, thereby increasing buy pressure for the Bitcoin coin while paying Bitcoin miners higher fees. VeriBlock also gives Bitcoin's PoW an eco-friendly image because it's PoW can be reused to secure a limitless number of blockchains.


How Hard is it to Attack a Blockchain Secured by VeriBlock?
Once a given block on a VeriBlock-secured blockchain reaches full security (after a period of time dependent on the aggression of the weighting algorithm employed by the blockchain and the absence of conflicting data, which is seen in real time), reversing consensus on that block would require forking Bitcoin, VeriBlock, and the VeriBlock-secured blockchain simultaneously.


How is VeriBlock Different From Sidechains/Drivechain?
VeriBlock Proof-of-Proof is a complementary technology to sidechains/Drivechain. Provided a sufficient security budget, a sidechain can adopt VeriBlock consensus technology just like any other public blockchain.


Why does VeriBlock Require a Coin?
The VeriBlock blockchain provides an aggregation layer of proof, and its coin provides a means for paying the decentralized VeriBlock PoW and PoP miners in a way controlled completely by the VeriBlock blockchain protocol. As such, the VeriBlock coin serves as a price discovery mechanism that allows the efficient allocation of the scare resource of proof, allowing all blockchains to inherit Bitcoin's PoW security.


What is Required for Proof-of-Proof Mining?
In order to earn VeriBlock testnet coins for PoP mining, you will need a running instance of Bitcoin Testnet (Mainnet VeriBlock will require Mainnet Bitcoin), with an address containing a positive Bitcoin balance. In addition, you will need the free VeriBlock Core Software (NodeCore, the CLI, and the PoP Miner).


What is Required for Proof-of-Work Mining?
In order to earn VeriBlock testnet coins for PoW mining, you will need a computer with unused CPU (or later, GPU) power. In addition, you will need the free VeriBlock Core Software (NodeCore, the CLI, and the PoW Miner).


What is vBlake?
vBlake is the Proof-of-Work hashing algorithm used by the VeriBlock blockchain. It is a tweaked version of BLAKE2b optimized for use as a PoW algorithm.

  guys, do you see the future potential revenue in this coin? maybe you have any forecasts for the price of this coin and its circulation? I really like this project because it has a real adoption with a noble goal, joined it with my computer but now I have thoughts to buy a powerful computer to join this project. would be any advices? or you can share your experience  Smiley

Since most cryptos spend huge amounts of electricity and thus release kilotons of CO2 in the atmosphere just to compute meaningless hashes (Bitcoin's yearly electricity consumption is pretty much the same as Peru's or New Zealand's) we can imagine that sooner or later governments may end-up banishing this kind of waste of energy so having bet on CureCoin with its PoW-free model (Curecoin 2.0 to be released soon this year Grin) would be a good thing.

Besides, CURE2.0 will be Quantum Computing resistant and is expected to have other nice features.

All these should be enough to make you take a decision especially if you are already aware that Folding helps Science.

Still, even with a powerful computer, don't expect to get rich overnight when you take into account that Vorksholk alone runs about 150 1080Ti GPUs (which by the way is a good sign he believes in the potential of this coin).



 

The core codebase behind 2.0 (which I'm developing in conjunction with a larger overall blockchain platform project) is still going well and we're primarily working on stability and performance testing, and the next step is to redo the certificate system to be more robust and allow us to easily onboard DCNs in the future using a "root certificate" system similar to CAs. All the quantum computing crypto and mini-blockchain ledger work is done.

Hey everyone, we've been getting some questions about cc2.0.

Short story is that development on codebase I'm currently working on for another project (which Curecoin will be a derivative of) is still progressing very well, but still needs some tweaks and supporting software (like optimized mining software) to make the launch as successful as possible. We are targeting sometime in Q1 (February?) for the initial cc2.0 release, which will occur (and directly benefit from, code-wise) after the launch of the other project I'm working on.
26  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN]CureCoin - CURECOIN TEAM HAS TAKEN RANK 1 ON FOLDING@HOME!!! on: December 26, 2017, 04:26:47 AM
What is the max number of coin ?

For CureCoin 1.0: Probably around 27M, where it depends on the POS extraction rate. The top 6 wallets on the blockchain explorer are the distribution addresses for doing Folding@Home work. The first 4-year blockchain distribution halving will be in about May 2018.   Smiley

there is below 8 millions in circulation!
the rest is reserved as folding rewards for upcoming years
a bad concept that will be changed in CC2
so that existing coins = circulating coins i hope


Yes, the CC2.0 release will make existing coins and circulating coins the same number, and future coins which reward folding will be paid out from the coinbase rather than the premined folding pool tokens. Smiley

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.

Hey, Curecoin 2.0 (which we're hoping to release the "code complete" testnet of sometime around New Year's 2018, and mainnet when the community and developers are satisfied with it's stability) will have QC-resistant Merkle Signatures implemented, although the current version of Curecoin uses the same cryptography (ECDSA with the secp256k1 curve) as Bitcoin. Cheers to a 2018: the year of post-QC crypto!

Nice rise on bittrex right now, is CURE related to FLDC??

They are both based on points accumulated by running the F@H software, but the dev teams and the technologies behind each coin are different.

CURE is an independent blockchain, and FLDC is a Counterparty asset. They can be "merge-folded" wherein someone can earn CURE and FLDC simultaneously. Smiley
29  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN]CureCoin - CURECOIN TEAM HAS TAKEN RANK 1 ON FOLDING@HOME!!! on: September 25, 2017, 02:23:30 AM
Goodbye.

 Vorshalk's "farm" is killing profitability on both CureCoin AND Foldingcoin, which I classify as ABUSE BY A DEVELOPER and am not willing to put up with any more.

 This is NOT going to "increase the price of the coin" - the SAME number of coins still get generated, they STILL end up getting spent - "donating them to charity" just means the CHARITY ends up spending them at which point they're right back into circulation.

 The ONLY effect of this massive farm is to KILL PROFITABILITY FOR THOSE OF US PARTICIPATING IN BOTH PROJECTS.


 If he really wanted to increase the price of the coin, he'd put the $100,000 (OR MORE, since he said he was using rigs with ONE GPU PER RIG) into BUYING CURECOIN instead - which WOULD increase the price of the coin, and if he then HELD ON to the Curecoin he bought it would also reduce the supply FOR REAL helping prop the price up.


 I am also starting to wonder VERY SERIOUSLY where he is getting the money to BUILD this farm - he's not like Ed Olkkola who is KNOWN to have a high-pay type job as an executive for an "investment banker" type company and has built his farm up over years.



 I can see it being reasonable for a Developer of a coin to have a FEW rigs for testing with.
 100+ RIGS that are eating over 10% of the profitability of the coin AND STILL GROWING IN NUMBER AND PROFITABILITY KILLING is not reasonable by ANY standard.




Anyone is free to build and deploy any number of servers for Curecoin folding (or any other type of mining in the cryptocurrency ecosystem); the entire ethos of this space relies on the permissionless nature of blockchain technology. No projects in this space can be built with any expectation of profit--the availability of hardware and performance of software will dictate the amount of folding/mining. It's a free market, and anyone is able to participate at any level. Curecoin developers don't have any advantage over anyone else in the ecosystem; would people be upset if a large folder unrelated to the development team were to come in and do the exact same thing? The fact that I'm involved in the project shouldn't limit my ability to participate compared to anyone else who isn't contributing code/ideas to the project. I'm not making any changes to the protocol or otherwise modifying the project in any way that benefits me, I'm simply paying money to build out infrastructure, and using it for folding for now.

I'm not going to purchase Curecoin for the sake of holding up the market--the goal of Curecoin is to drastically improve the computational resources put towards groundbreaking medical research, not ensure a profit margin for a particular user. The farm is no longer growing (and hasn't for a while), and it's around 8% of the total folding power, I believe. Building a mining rig is a calculated risk, and decisions should be made based on expected market growth/decline, profit margin predictions, alternative uses for the hardware that also generate profit, etc. Assuming that someone won't step in and benefit from an economic incentive is a bit silly, whether they're a developer of the project or not.

Sorry to see you go Sad

Good question! Yes, certificate authorities will sign certificates which certify that a particular user (as identified by a Curecoin address) did a certain quantity of work. The certificate gives a range of nonces that that user is allowed to try mining with, and if they get a nonce in the provided range that, when combined with the previous block hash (as defined by the certificate), and their address (as defined by the certificate), they are allowed to make a block.


 This sounds like you're now expecting Folders to mine as well to get our rewards?

 Or am I being confused?



Folders will also 'mine' but in a similar way to PoS (as far as how many computations are done). The certificate might give, say, 400,000 nonces for 8 hours of folding work, but the miner could run through those 400,000 nonces on a CPU in far less than a single second.

Does it mean that folders will have to run a specific mining software to perform that task?
Or will it be included in the wallet?
And what if somebody doesn't want to keep his wallet "open"/online fulltime?
If the computer/rig holding that software crashes, will the folder lose the coins corresponding to what he folded during the crash if the computer isn't rebooted?
Will it be possible to have several instances of that mining software running in parallel on different computers/rigs to prevent this problem?

Oh and by the way, what about SigmaX? Will it finally also be released? Do you have more information about the distribution process?

Lots of questions Smiley

Lots of good questions!

The folder will not necessarily have to run specific mining software, since they could opt to join a pool instead (where their certificate goes to the pool, and an 'extraData' section of the certificate becomes the worker, or similar).

If they want to 'solo-fold' then they'll have to run a small additional 'bridge' software or similar, which receives the certificates and tries to process them. Most likely, this will be part of the Curecoin wallet itself, which would need to be open for solo folding.

There is a potential for downtime being an issue if, immediately before or upon receipt of a certificate, the client crashed and was unable to actually mine with the certificate (and the network passes them by, creating other valid blocks instead). There would be the option for serious folders to have some redundancy system wherein all certificates mined by a particular individual would be sent to multiple machines which all attempt mining. This wouldn't increase any mining odds, but only prevent a system's failure from interfering with mining a block using an awarded certificate.

Not sure what exactly SigmaX will look like, but it's still on the docket. Basically cc2.0 but with the certificate system replaced by traditional PoW. It'll be released after cc2.0, and the distribution is still up for discussion (although we'd like to give SigmaX tokens to existing Curecoin holders, perhaps similar to the Byteball distribution mechanism?).

Given the problems with the Stanford stat server, will there be a distributed system for the certificate authorities.  If they can't be bothered to maintain a simple server I'm not sure how much faith I have in them issuing certificates.

Great question! Two things will be in place:
-Multiple CAs (if one goes down, their difficulty just falls while the other CAs (say, GPUGrid) continue to successfully issue certificates)
-Curecoin devs will also have the ability to automatically create blocks with no reward/fee during times of DCN disruption as a "last resport," simply to help network congestion [fees of included transactions will either be burnt, provably sent to charity, or forwarded to future block minters]

Obviously still a semi-centralized solution as anything like Curecoin is bound to be, but it's designed to best handle any issues in the best possible manner considering the constraints of a blockchain designed around DCNs. Smiley

frankly speaking,we got more promise from team but we did not see any code even a single line of code.

curecoin clone from ltc or not ?

CC2.0 is a completely brand-new codebase.

is CC2 POF (prove of folding) only or hybrid POF+POS ?

Good question! We haven't yet decided on whether PoS (or a similar system) will be used at all. It complicates thin-client support, but might act as a nice counter-balance for the certificate blockchain system in a "jigsaw-blockchain" (where several types of blocks are all required to exist in some capacity in a given period of 'n' blocks).

Curecoin 2.0 uses a mini-blockchain which drastically reduces the footprint of the blockchain (and makes thin clients very lightweight), implements quantum-computer-resistant cryptography, and will have an as-close-to-decentralized-as-possible distribution mechanism for folding rewards.

Wow, this is an important and useful evolution for future. Reducing blockchain's footprint is really useful in future when blockchain grown. This is the main issue of most coins that we have to download 100GB or more in order to perform any transaction in the wallet.

We're excited about it! Cryptonight pioneered the idea, and we see tons of value in it. While there will certainly be archival nodes which maintain a full history (blockchain explorers, etc.), being able to maintain a blockchain that grows with # of users rather than # of transactions should certainly be valuable!

I see this whole "certificate" concept as just adding one more layer of complexity and confusion with no benefit at all to those of us that fold, especially since a normal Folding rig generally already HAS it's CPU cores tied up feeding data to the GPUs to DO the folding with.

 Might be less of an issue if you include the "mining" software as an inherent part of the wallet.


For users who want to continue mining similar to how they do today, they can simply use a pool, and the pool will handle the complexity of the certificate system Smiley...
And where is that pool tree that the pool software grows on? Roll Eyes

We will release some basic pool software Smiley

I can't see the trivial amount of resources used to do the actual mining as a big problem, especially since most will probably be using a pool to do that part anyway.

I think the ability to be able to contribute to a wider range of projects and have more certificate authorities, and the decentralization that brings, far outweighs having to have a second type of client or a wallet open while you're mining folding.

btw what other projects/cert authorities will be coming on board...or is it too early to tell still?

Yup, I don't expect the complexity of the certificate system to drive anyone away from folding, since pools will exist and users can just fold under the pool address or similar.

For other projects we don't have a specific guaranteed list, but GPUGrid was responsive to our inquiries a while ago, so they'd probably be one of the first additional projects we add.

I think the halving is about every 4 years, so more like May 2018.   Smiley
The info is in the OP:

https://docs.google.com/spreadsheets/d/1BY-ezmmVbooFwa3dzJZowpYmxEu9HgO2o5FeR7Evc-U

Block 210240

With CC2.0 around the corner, is there a plan to burn the premine? Most of it could probably be burnt right now, and then the remainder just before the new coin launches.

Thanks for the information. Still a few months to go although less than a year from now. Sorry that I over look the OP, the spreadsheet stated clearly on coin distribution and halving details.

BTW, what are the new features in CC2.0?



The remaining initially mined tokens that haven't been distributed won't exist on the cc2.0 blockchain, so it'll be burnt or something similar (unless cc1.0 stays around as a merge-folded coin or something that we still do payouts on, but those tokens will be 'effectively' destroyed in cc2.0 because they still won't transfer).

Curecoin 2.0 uses a mini-blockchain which drastically reduces the footprint of the blockchain (and makes thin clients very lightweight), implements quantum-computer-resistant cryptography, and will have an as-close-to-decentralized-as-possible distribution mechanism for folding rewards.

Well medicine is just one (but certainly not the only) field that can greatly benefit from AI, so it is related. Anyhow I was just curious. Thanks for the response!

For the way the mining works, I think it sounds pretty good. Obviously it can't be completely decentralized since the computations have to be something useful to a scientist/lab/institution and are going to be highly specific to the research project. I don't know how you would make a generalized PoW algorithm that produces useful work for a wide range of research projects. Anyhow, the more projects/certificate authorities there are to choose from, the more decentralized it would be. Even with just F@H issuing certificates for now, it sounds like it will still be way more trustless than the current system of millions of premined coins.

Will folders be able to pool their certificates so they won't have to 'solo mine' an entire block to get rewards?

Yup, exactly! Someone has to decide what constitutes an "interesting" computational problem to solve, the closest we can really get would be things like prime number searches or looking for insight into problems like the Collatz Conjecture, with very well-known properties.

And yes, it will be possible to pool mine with the certificate system.

Can someone from the team explain a bit how the "folding" blocks are created and distributed in CC 2.0?

My understanding is that there will be no more need for a pre-mined amount that requires someone to distribute it; but that it will be based on certificates issued by Stanford (for folding work) and Berkeley, or whoever else (for BOINC projects and other work); and so coins will only be created as blocks are "mined".
But, without getting too technical, how does the network interact with the certificate authorities to decide what address to award a block to? Will each authority have to maintain their own "pool" in a sense? If so, how would each so-called pool be weighted?

Also will there still be a portion of rewards that go to ASIC miners for traditional PoW mining?

Thanks, and great job! Looking forward to seeing how this plays out. It would be awesome if pointing rigs toward scientific research was the most profitable thing to do (or at least on par) and everyone starts doing it.

P.S. I don't know if you'll have an answer for this one, but will distributed AI research projects be one of the things you can do for rewards? Seems there would be a huge demand for this kind of research, both right now and for the foreseeable future.

Thanks again!

Good question! Yes, certificate authorities will sign certificates which certify that a particular user (as identified by a Curecoin address) did a certain quantity of work. The certificate gives a range of nonces that that user is allowed to try mining with, and if they get a nonce in the provided range that, when combined with the previous block hash (as defined by the certificate), and their address (as defined by the certificate), they are allowed to make a block.

Obviously still a fairly centralized solution, but the design of the certificate system does mean that no signature authority can know ahead-of-time whether a particular certificate they issue will mine a valid block or not.

There will not be any traditional PoW mining on this network.

Not sure about the distributed AI research, but if it is related to medicine, there's a good chance Curecoin would adopt the DCN sometime in the future Smiley

While obviously not a "valid" thing to do:
Code:
submitblock 1503549351863:4:000000004CD8AF81DA2019F24207545DFDD3F97651A
E500CEBB361FE897E82E8:500000000
rather than
Code:
1503549351863:4:000000004CD8AF81DA2019F24207545DFDD3F97651A
E500CEBB361FE897E82E8:500000000:4326510258612929541:C162W5TNLB5OWWYUSSWBSQJWWW5Z

will crash the client and leave the following in the daemon:
Code:
net.curecoin.curecoin.exceptions.BlockFormatException: Too few block chunks! Blo

Thanks for the bug report! Noted.

Here's a version that should fix this bug:

70x1080s!!!
That's about 15kW power and heat.
Have you just moved to Greenland or some icy area like that? Cheesy
Let's see Ed's and Cure4All's responses Smiley

 More - my triple rig 1080 pulls almost 800 watts, if his are all single-card rigs he's probably pulling more like 25-30KW.



Luckily they're in a datacenter so I don't have to deal with the heat dissipation Smiley
These GPUs aren't necessarily Curecoin-dedicated (building out a GPU farm for several reasons), but they're default use is folding.
