I believe that the coin aim is to replace the useless mining of the other coins with useful computation.
In this regard, the dogecoin effort doesn't deliver, nor does the current curecoin implementation.
But version 2 will, so I am really looking forward to it!
Let's hope people will understand the importance of this aspect of cryptocurrencies.

Yep, I completely agree.  The wasted energy and the actual release of Curecoin is why I stopped mining Dogecoin myself.  Without usage of the coin though Curecoin is in a tough spot.

I'm a believer in research based crypto.  I have no idea what that will ultimately look like in a few years with the various progressions but I do believe the two concepts are perfect for each other.

Of course there would be other difficult problems with "attaching" to another coin as well such as what would be done with the existing coins that we already have.  So I suspect any possibility of doing that is already too late.

Yeah, attaching to another coin at this point in time wouldn't make much sense.

4.) There will be a limited amount of coins that can be minted using certificate mining (however this will be stretched out over a very long period of time, and will be practical for encouraging computational research far into the future). If we implement a Proof-Of-Stake model, then we will see some form of interest, which will be rate-limited, but not limited to an actual final quantity. Hopefully that makes sense, let me know if you'd like me to clarify that one.


Thank you for your answers. I have some follow up questions regarding this point.

Why put a limit on the amount of coin to be minted using the certificate mining? I understand it will be stretch over a very long time but why have the limit in the first place? Why not  make it rate-limited somehow without a limited final quantity? Having it finite means that there will be a point in time in the future that would deem certificate mining unprofitable and people, being financially incentivized, will move from it to more profitable venues. Be it 10 days from now or 10 million years from now, that point in time will come and people will move away. Could you please elaborate more on the decisions to set a limit on coin mined with certificate mining and the thought process behind them ?

Thank you

Yeah, this part isn't actually set in stone, so if other people have input on this, don't be shy! Had a discussion with Cygnus and Cujo about this last night. Smiley

I'm thinking the best path might be a compromise between people wanting a set-limit system and an actual currency's behavior. Bitcoin and almost every other cryptocurrency has some finite limit to it's mintage, attractive to investors as it is scarce, similar to a commodity. On the other side, fiat currencies are designed in such a way that their mintage is based on a lot of factors including population, and tend to become less valuable over time, per unit. As a result, a compromise would be a very long mintage schedule with an extremely gradual decline, so the coin is still generated at a predictable rate, but is still limited in supply in a given period of time.

Just my 2 cents...  I do think a coin that follows a very small inflationary model is a good idea but only to the extent that it is slightly higher than what is needed to offset coins that will get lost via people losing interest, losing their hard drive with no backups, or forgetting their pass phrase etc.  I have no idea how to estimate what the natural deflation rate is but I wouldn't want to see growth being much higher than the best guess. 

My biggest concern as I've mentioned before is coin utilization.  If we don't find ways to actually use CureCoin, the coin is going to die no matter what its features.  People need to be able to use it and right now there is nothing to use it for.  That is the number one problem in my view.  Of course we can use it for speculation but that can be done with a thousand other coins as well.  We need real uses for CureCoin.

Maybe when CC 2.0 is released the devs can approach Moolah and others to see if they have an interest in working with the coin.  It would seem to fit in well with their mindset and could possibly bring in the Dogecoin community, but I don't think they would be interested under the current structure.  CC 2.0 should alleviate many concerns that would come up.  I would love to find a way to introduce CureCoin to the Dogecoin crowd.  Most members of the Dogecoin community can't mine anymore since the implementation of AuxPoW due to the soaring difficultly.  It would be nice to get a few over here and create a cross community if possible.  If we could find a way to tap into the DOGE community I think CureCoin's demand would skyrocket.

It appears I have veered off topic a bit from the original quote so I guess I put in 4 cents instead of my 2 cents.   Grin

I've been away for a while so this is a little late lol but here goes.

I completely agree that a well established currency that's used for daily transactions should NOT be deflationary. It should have an inflation that is organic and healthy for the growth of developing economies. I did some random readings on the topic and it  appears that an inflation rate between %1 and %3 correlates with healthy growing economies in developing countries ( curecoin is an economic ecosystem that will represent a digital form of a growing developing country) .. Therefore I highly highly HIGHLY discourage setting a hard limit on the supply. Give it an inflationary nature that reaches that optimum inflation rate between 1-3% that takes into account transaction fees are destroyed to balance the inflation. Economically speaking, this is the way to go. The Bitcoin simulation of precious metals and deflationary nature of it while exciting at first, it fails to be a medium of exchange for daily transactions due to the hoarding nature it has by the idea that the Bitcoin I hold today will be worth more tomorrow since there will be less to mine. It discourages economical growth on the long run by promoting hoarding and discouraging transacting in it.

Speaking of transacting and encouraging it, I've read that a healthy economy grows healthier with increased amount of transactions that occur in it. Therefore a model that encourages spending and discourages hoarding would be optimal. The REDDCOIN team have attempted to tackle that aspect and came in with Proof Of Stak Velocity ( POSV) . I invite the debs to read the REDDCOIN white paper and explore the possible use of a POSV model rather than POS or proof of capacity along side the proof of certificate Smiley

On another random note , I had lost the link to http://curecoinfolding.com/progress-updates-p2p-networking/ then I realized it's not on the curecoin.net website. I really think a link to the curecoinfolding.com website should be on the curecoin.net as I never really knew about that site until and accidently came by it.

PoSV is a very interesting concept, however it has a number of potential drawbacks I see occurring, namely involving unnecessary blockchain bloat. It seems any method of encouraging higher transaction volume wouldn't actually encourage more spending, but rather simply cause tons of 'useless' transactions where a coin holder simply sends coins to another address they own.

That being said, right now we're looking at some form of anti-inflationary mintage schedule similar to what you described above, which would kick into effect after the classic mintage period finishes. As you said, simulating a precious commodity has to give at some point, if Curecoin is to be used as a currency.

Marketing and creating usability for the coin will become top prioirty AFTER the implementation of the system. I see GREAT potential! For example, curecoin would require/encourage universities that want to apply as a signing authority to accept curecoin on campus for tuition and other stuff. Why would they do that? Cause it'll encourage more people to do proof of certificate work which will the help the university's research further develop. Not to mention the amazing PR the university would get for accepting a humane crypto currency. I know it's frustrating now with the price guys but once the system is implemented, the uses would endless. Heck we could create a fork of some sort that "rents out" computational power to private companies by giving them signing authority for a fee or a donation that could require the fee to paid only in curecoin and for a limited period of time for example. You know how much potential income could be generated by renting computational power ?? Great potential .. See what's coming not what's under your feet guys Wink

Yup, we're stuck in a bit of a hard spot right now, simply because we don't want to push for too much merchant/exchange integration before we completely change the codebase on them! That being said, once we have a final system in place and further improvements are made to the platform without requiring new APIs to be implemented for use, promotion/marketing is the number one objective. Thanks for the positive words!

hello all, I need some help, trying to solomine this coin, I have some rockminers, some dragon miners and some zeus miners. None are working, the sha-256 equipment gives me a reading as if I am using the wrong equipment with this coin. It says everywhere even the pools this is a sha-256 coin but none of my sha equipment can mine it. So since the miner program gave me the errors as if i were using the wrong equipment with this algo i tried my zeus, becasue the difficulty in the wallet says 0.002 thus would mean its probably a scrypt coin with a difficulty that low, the zeus did connect yet mined nothing. It was hashing, however with a difficulty of 0.002 I would hope to get at least 1 block with my zeus blizzard 4 Mhash/s machine in an hour right?

SO what am I doing wrong here,

Added note the wallet about says its an X11 scrypt coin is this true? that would explain why the difficulty is rated in the wallet at 0.002 and why my shaminers cant connect or force the chainstate as well as why y zeus is not processing blocks.

That's... very odd. Have you had luck solo-mining other similar SHA256 coins? Curecoin is SHA256 for sure.

...a signing algorithm which is resistant to Quantum Computers ...

I keep reading it, but also keep not understanding it. Is this relevant for today's implementations ? Google seems to have something like an QC in the corner, NSA maybe too.

Having it conceptual in mind is good, but need to spend efforts on it ? Can it be tested/validated ? Does it scares people off as techie-talk ?

But again, I keep not understanding it. Can you explain it in simple terms to me ?

Basically, modern signature schemes are based off of the multiplication of large prime numbers, and Shor's algorithm allows quantum computers to find the prime factorization of large numbers. Shor's algorithm requires a quantum computer to run, and thus factoring large numbers into their source prime numbers becomes practical.

I'll give an example of RSA because it's much more straight-forward, but keep in mind a similar issue exists in a more complex form inside of ECDSA. (The following steps are information-only, you can skip them if you wish. If you want an example of creating/breaking an RSA key, you're in the right place. Summary at the bottom!)
Code:
For public/private key cryptography, you need to generate a private key, and from this private key you can create or derive your public key. In the case of RSA, you generate a public key in the following manner:
1.) Choose two unique, large prime numbers. (p and q)
2.) Multiply these unique primes together (result = n)
3.) Compute: (p-1)*(q-1) (result = φ)
4.) Pick an integer between 1 and φ which doesn't share a prime factor with φ (result = e)
5.) Figure out what number (d) when multiplied by (e/φ) gives 1. In other words, the remainder of (d*e)/φ is 1.

So, let's do an example! :)
1.) My two primes (obviously waaaay to small to ever be practical for actual cryptography): p=7 and q=13
2.) Multiply them(n=91)
3.) Multiply (p-1) with (q-1): (6*12)φ=72
4.) Pick an integer sharing no prime factor with φ:e=11
5.) Number which when multiplied by (e/φ) gives us a remainder of one:d=51
-->Check: d*(e/φ)=649/72=9 + 1/72 or 9 remainder 1. YAY!

Now, your public key is the two numbers 'e' and 'n', so our public key is (11, 91).
Your private key is the two numbers 'd' and 'n', so our private key is (51, 91).

Now, of course these numbers are ridiculously small and not practical for encryption, but let's demonstrate breaking this simple RSA key given the availability of a 'function' B(x) which, when fed a number, would return the prime factorization. Example: B(391) returns two numbers: 17 and 23. THIS FUNCTION B(x) is what quantum computers would provide.

Given only the public key, we have two variables initially:
e = 11
n = 91
As you can see above, if we could calculate both p and q (the initial starting prime numbers), we could re-calculate the private key d. Given the starting primes, finding 'd' is deterministic. So, our only goal here is to calculate p and q. We already know pq, and we know p and q are both primes. To this effect, calling B(n) or B(91) yields {7, 13}. However, if we were unable to easily find the prime factorization of 91, we would be stuck brute-forcing:
2*x=91 (x not integer)
3*x=91 (x not integer)
5*x=91 (x not integer)
7*x=91 (x is an integer)
For very large values of  n, brute-forcing becomes computationally-infeasible. Another means of attacking RSA keys is the number field sieve, which is significantly more effective, and was used to crack a 768-bit RSA key. For a key of size 3072-bit, it would take all the computing power on Earth today longer (by orders of magnitude) than the age of the known universe to factor this number 'e' back into parts 'p' and 'q'.

Or, with a quantum computer of large enough (around 6144 'qubits' or quantum bits, a unit of quantum information which can exist in a superposition where it is both 1 AND 0), you'd just use Shor's algorithm (which has been demonstrated in factoring '15' into '3' and '5' (not impressive in itself of course, but the technology exists and Shor's algorithm is provably feasible) to call B(n).

Summary: RSA is vulnerable to quantum computers. A component of the public RSA key (n) is simply the product of two very large prime numbers. The infeasibility of factoring n into the two original primes p and q is an essential property of RSA's integrity. If a method were created which, when given a number, was able to efficiently calculate the prime factorization, it would break RSA. Shor's algorithm can factor extremely large numbers into a prime factorization in a practical timeframe. If quantum computers were stable and were scalable to a desired size, Shor's algorithm would be able to factor an RSA public key to an RSA private key.

Bitcoin doesn't use RSA, it uses ECDSA. However, Shor's 2nd algorithm from 1994 allows for solving discrete logarithms could attack ECDSA. Additionally, a smaller quantum computer would be required to attack a classically-similar security of ECDSA than for RSA (Breaking a 2048-bit RSA key needs around 4096 qubits, breaking a 224-bit ECDSA key would need somewhere between 1300 and 1600 qubits). If you're interested in reading a very dense document on quantum computers applied to Elliptical Curve Crypto, check out http://arxiv.org/pdf/quant-ph/0301141v2.pdf.

One of Shor's proposed algorithms from 1994 allows for quantum computers to "easily" solve discrete logarithms. So, what does this mean? (You can skip this section as well)

Code:
The discrete logarithm problem is another mathematical entity believed to be easy one way, hard the other.
For example:
q^b mod n ≡ x
Where n is a primitive root of q (basically, for all possible values of r, the chances of getting any result (1, 2, 3, 4, 5, 6) from (q^b MOD n) is equal)
Solve for x.
Knowing n, q, and b, this can be calculated very easily. Let's say n = 13. 6 is a primitive root.
How we know 6 is a primitive root of 13:
6^1 MOD 13 = 6
6^2 MOD 13 = 10
6^3 MOD 13 = 8
6^4 MOD 13 = 9
6^5 MOD 13 = 2
6^6 MOD 13 = 12
6^7 MOD 13 = 7
6^8 MOD 13 = 3
6^9 MOD 13 = 5
6^10 MOD 13 = 4
6^11 MOD 13 = 11
6^12 MOD 13 = 1
6^13 MOD 13 = 6
6^14 MOD 13 = 10
6^15 MOD 13 = 8
etc... You can see a pattern. 6^1 MOD 13 is the same as 6^13 MOD 13 is the same as 6^25 MOD 13 is the same as 6^37 MOD 13. Using this looping pattern, we can predict 6^1994833 MOD 6 as being 6. Why? Because (1994833-1)/12 is an integer. We don't have to calculate 6^1994833, we just use a pattern. Cool, huh? 6^1994834 MOD 13 is 10. 6^1994835 MOD 13 is 8. Etc. Not really important to what we're doing right now, it's just awesome. :D

Aaaanyhow, back to what we were doing.
 q^b mod n ≡ x
Let's set q as 6, n as 13, and b as 119. We could either use our pattern above or resort to asking a calculator, but x is easy to calculate. x = 11.
That's easy. Now, try calculating:
6^b mod 13 = 119.
For such a small modulus 13, this problem is trivial trial-and error. However, this problem becomes far more difficult with extremely large moduli, similar to a prime factorization.

So, let's summarize what we know so far.
Bitcoin uses ECDSA
ECDSA relies on the hardness of Discrete Logarithms.
Discrete Logarithms can be easily solved by an algorithm by Peter Shor on quantum computational devices.

So, if quantum computers can break ECDSA, how vulnerable is Bitcoin?



The above image explains the basic process for generating a Bitcoin address. The address itself cannot be reversed to the public key of the ECDSA keypair, because it is protected by a hash. However, when you create and sign a transaction (spend Bitcoins, namely), your public key is revealed. Peers re-calculate your address based on the public key you revealed to the network, and if the produced address matches the source address, and the signature matches the public key, the transaction is accepted.

So, coins sent to a Bitcoin address that has never sent a transaction can not be spent by someone with a Quantum computer. However, any address on the Bitcoin network that has previously made a transaction can be reversed to its private key, and an attacker can then empty the address.

As such, Bitcoin addresses would have to be one-time-use, which isn't exactly practical.

No quantum computers are available today which can crack ECDSA. Nor will they be here next year.

Quantum-resistant signing algorithms are proven effective. They rely only on the existence of a hashing function that is one-way by design, which is fulfilled perfectly fine by SHA256, SHA3, RIPE160, Grostel, etc. etc. Quantum computers can't brute-force deterministic circuit-logic operations in a cost-effective manner.

Hopefully that all made sense, I didn't expect to write a novella >.> Let me know if you have any other questions!

Hey Curecoin, let's work together?

.  ethical coins unite ..., let's join forces for specific projects.

Do you have a specific project that relates to science and are looking for a support partner, if so call on Einsteinium we will do what we can to forward your project.   

Support partners usually will pledge to retweet, provide comments, likes, small donations, and endorsements for specific events they choose to get involved with.

Einsteinium is a 'cause coin' we seek to provide funding for science endeavors, we are seeking project partners for small projects involving: educational science. science fairs, science instructors (teachers, professors, mentors, etc ...), or anything else that has a heavy science influence.



Ebola is topical subject, EMC2 is considering making a public donation, we need to know if you are willing to join our campaign if we carry it forward?



What kind of participation are you looking for? Smiley

How many people are mining Btc and alt's?

I think there are enough who are folding:
http://folding.extremeoverclocking.com/team_list.php?s=

Curecoin had a output of 4,012,966,688 points in May!
These people where not only "new" folding miners, some were for sure people of other teams, but they are all back in their old teams and the miners are looking at the current price........ Embarrassed


Quite a few people are still folding, we're nearly double the daily production of our closest competitor! Smiley

seems the coin is dying. it had decent idea but somehow peopel dint follow.
real sham as this oculd help many lives Sad

It's not dying, we're in a lull period while writing extensive amounts of code for cc2.0/3.0.

is the block explorer down? it says "coucou".

Certainly seems to be down, that block explorer seems to have had some problems lately. Curecoin 3.0 will have a built-in block explorer.

The graph of curecoin value is pretty disheartening. Essentially no upward movement for its entire life....yet I keep buying more and folding because I believe in the cause. Can anyone give some reasons why the downward movement won't continue? Any big plans that will increase the value long-term?

As a pretty vocal supporter of Curecoin I really wish I could say I'm aware of plans that will increase the long-term value of the coin, but sadly I'm not aware of any.  CC 2.0 is certainly an improvement, but unless universities literally get behind CC 2.0 I'm still not sure where the value will come from.

Additionally, it doesn't appear that the folding community is large enough to build an economy themselves such as with Dogecoin.

I'm no economist and can't make any predictions about future price with any kind of certainty (hey, it's crypto!), but one of the roadblocks to the next generation of Curecoin is getting universities to integrate certificate signing into their existing computational research projects. We're working on making sure this integration is as easy and faultless as possible, which should ease any University's resistance towards implementing Curecoin into their work. Value is certainly an odd concept in cryptocurrency, and no one is entirely sure where value for any coin truly comes from. Some of it comes from speculation, some from utility, some from blind diversification, some from market manipulation, and some seems to materialize out of thin air. The hope is that the utility of Curecoin will push it to a higher valuation--it will offer similar utility to existing cryptocurrencies, and will have a signing algorithm which is resistant to Quantum Computers, unlike Bitcoin/Litecoin/Peercoin/Dogecoin...etc's ECDSA. Additionally, it is a significantly cleaner alternative to traditional mining--all computational power pointed towards generating coins is doing valuable computational research, and the relationship with university research facilities will hopefully increase the public image and set it aside from the black-market-related image that most major cryptocurrencies have been unfortunately shaded with.

In addition to programming, the team is working with media contacts to further Curecoin's media exposure, though this has proven to be a lengthy process.

387  Alternate cryptocurrencies / Announcements (Altcoins) / Re: Curecoin 2.0 Questions on: September 19, 2014, 12:46:58 PM
Hi

I am working on a couple of projects that I would like to integrate Curecoin in as I believe in what it stands for. Having said that, I'm hesitant to work on incorporating it at the time being when knowing there is a complete rewriting of the source code coming in Curecoin 2.0 . The projects i'm implementing rely heavily on the RPC API calls and on multisig transactions.

I have the following questions:

1- will Curecoin 2.0 support multisig addresses and transactions ?

2- will Curecoin 2.0 support RPC calls like the current client does? Will it provide the current API calls and add new ones or should I wait until the client is released and work with a complete new set of API calls? I don't want to waste time and energy by implementing applications relying on an API that will be outdated and deprecated on the next release.

3- Aside from the folding/research computations for the proof of work, will curecoin 2.0 have another system to maintain the security of the network? Possibly Proof of Stake like Peercoin (a coin I believe in the ideals behind it like I do in Curecoin) http://peercoin.net/minting  ? or Proof Of Resources like which is a new concept that is quite interesting to be used by Safecoin, a coin still in development http://www.safecoin.io/ ? I read in the article http://curecoinfolding.com/progress-updates-p2p-networking/ that a Proof of Capacity is being considered but i couldn't find more information on the topic of Proof of Capacity. Could you please elaborate on what other means of securing the network aside from doing the research computations will be?

4- will there be a set limit on the amount of curecoins generated like in the case of Bitcoin or will it have an inflationary and deflationary aspects that will balance each other like in the case of Peercoin without a preset cap on curecoins?

5- I come to understand that for research to be added, the researchers will have to setup a centralized certificate issuing entity for validation. How could research that is completely decentralized be included in Curecoin with the proposed certificate model? An example of decentralized research computations that doesn't require a central authority is the search for prime numbers like in the case of Primecoin http://primecoin.io/ . How would such research be included in the curecoin model without a central authority issuing certificates? I could see great potential in merging primecoin with the Curecoin 2.0. You would probably get all the supporters of Primecoin migrate to Curecoin 2.0 if the same kind of computation could be used a form of research computation used for mining Curecoin 2.0.

Looking forward to hearing back from you


Hey Indigo, good questions!

1.) Yup, full support for multisig addresses/transactions will be available. The process behind it will likely have to change due to the signature scheme we are working on, so there may be multisig 'accounts,' in which the blockchain has a written record of all the addresses involved in a multisig account, and can apply appropriate verification rules to make it behave similar to multisig. This will also allow you to sign on additional parties to the account.

2.) Curecoin will have a new API, since so much under the hood is changing. While we don't currently have a RPC reference of any sort, we're rebuilding the structure of interfacing with the daemon from scratch, so while some RPC calls will be very similar in function, there will be far more complicated ones to account for additional features.

3.) The blockchain should be secure enough using only a certificate system, given that certain rate-limiting rules are integrated into every node. However, I'm not opposed to putting some kind of Proof of Stake or Proof of Capacity into the currency. If you would like to look at a current example of Proof-Of-Capacity, check out Burstcoin. Smiley

4.) There will be a limited amount of coins that can be minted using certificate mining (however this will be stretched out over a very long period of time, and will be practical for encouraging computational research far into the future). If we implement a Proof-Of-Stake model, then we will see some form of interest, which will be rate-limited, but not limited to an actual final quantity. Hopefully that makes sense, let me know if you'd like me to clarify that one.

5.) Unfortunately the design of a certificate system would require some authority to issue the certificates. For a very specific set of mathematical research, the solutions could be proven in the blockchain, however we don't plan to implement that feature, unless we can find a robust way to do so. Our logic essentially follows that *most* ground-breaking research requires fairly significant human intervention, from creating the workunits to be crunched for protein folding to developing climate predictions based on variables that scientists want to manipulate to best study their subject area. The few exceptions to such research are of course ones like Primecoin or Riecoin where the network looks for numbers that fit a given pattern that can be verified by the network. In order to do so, the Curecoin network would need a means of validating the work submitted, which, given the scope of potential research offered by deterministic work generation, doesn't seem terribly practical. That being said, if an extremely interesting research project which could behave in a decentralized manner was developed, the validation of that project could be added in a similar manner as adding an additional university to the network--and would require a client update.

Any kind of ETA for CC 2.0?

I'd like to say it'll be fully released by February (full crossplatform GUI, crossplatform daemon, exchanges, cc1.0<->2.0 trade working, etc.), and we'll have public (no value) betas before that, but you know how software development goes. I also don't know how much time it'll take to get universities on-board and signing certificates, but if the community is fine with it, we could be the issuing authority until the universities are ready to switch over. I'm not a huge fan of that idea, but it's on the table.

Took a break from coding curecoin core to do a bit of preliminary GUI mockups. This is what I came up with:



I would right-Align the numbers in the upper and lower section of the screen. Easier to read.



Ah good point, I'll fix that. Smiley


Hey guys, is this somehow related to you ? - https://bitcointalk.org/index.php?topic=781352.0

Similar idea, however we are completely unaffiliated.

How long would 4TB take to plot on a last gen i7 mobile? Anyone know how many nonces/second and how long it would take? How could I calculate this?

Don't wanna waste my time.

You're probably looking at somewhere between 4 and 5 days, depending on how good of a mobile i7 you have.

Is there any wiki/repository on plot speed vs cpu?

Not that I know of. Here's some basic performance metrics on Centos 6.5 with dcct's linux plotgen:
i5-2400: 3400 nonces/min
E5-2560v2: 7000 nonces/min
E5-2670v2: 7100 nonces/min
2xE5-2560v2: 13900 nonces/min
i7-3770k: 4300 nonces/min
FX-8350 @ 4.2GHz: 3500 nonces/min

Hey guys, thanks for the interest in MintPal! I'm afraid Curecoin is too low-volume right now to float on MintPal unfortunately, and I doubt MintPal would be likely to re-add a coin that they already delisted due to low trading volume.

If enough people are interested, I'll reach out to MintPal, but I was personally planning to wait until the volume began to pick up a bit more, maybe closer to cc2.0 release, when we have some solid pieces of infrastructure proven working, and there is more community interest.

I didn't know CureCoin had been on MintPal before.  Oops!  I thought we was on the voting page for MintPal and then they discontinued the voting process but I was quite busy for a while and apparently missed it.  In any event, waiting for cc2.0 or sometime near it is fine with me.  Their new volume requirements are actually quite low now so delisting shouldn't be an issue in the future.

Yeah I hope CureCoin 2.0 brings in more interest.  It's a great cause and I thought a lot more people would be on-board and stay on-board.  That isn't to say team CureCoin hasn't been doing great.  I just thought a lot more GPU's would find there way here when they couldn't "mine" other coins profitably anymore.  Hopefully cc2.0's changes will bring in more people and keep them.  In the mean time I'll just keep accumulating cc1.0's.

Oh, we were never on Mintpal. Just don't want to get added and then delisted due to low volume. Smiley

I have 4TB drives available to start generating plots immediately (which would take 2-3 days to complete) after which I could ship the drive. For other capacities, I would have to wait a few days for shipping to me first, so a 6TB drive would likely ship from me in about a week. The included shipping is UPS ground, though if you wanted the drive faster I can offer faster shipping for an additional fee.

What about renting?  Do you have plots ready to go for that?

For solo or pool mining, I would need to generate the plots for your own address, so unfortunately I can't pre-generate plots. However, I can deploy storage very quickly in the cloud.

How long will it take you to ship the drive?

Is there a way I can generate plots on a cloud server? How and where?
Yeah, you can, but storage ain't cheap..

How and where please? I would like to look at it from top to bottom and do a cost benefit analysis.

You can check out OVH's dedicated storage servers, which you can grab 48TB for $489.00/mo. That's around $120/TB/year. Or if you wanna go biger, 216TB will be $1659.00/mo, or around $92/TB/year. Keep in mind you'll need to generate all the plots too, so you might want to vRack that with a powerful "Big-Data" server such as the HG (which could generate plots at a rate around 13900 nonces/min, as it has 2xE5-2650v2) or an Infrastructure server such as the EG-128 (which you can rent weekly for $100, and could generate around a rate of 7000 nonces/min) for a few weeks to generate all the plots, constantly moving them over the vRack connection.

Alternately, you could rent SYS servers such as their 24TB option for around $150 per month, or around $75/TB/year. Keep in mind that every TB of stated space is 0.9TB of space after formatting and creating the filesystem, so the 24TB server will give you 3.6TBx6=21.6TB after formatting and using "tune2fs -m 0 /dev/sdx." I also rent out burst mining power at a rate of 0.045BTC/TB for the first month (for an actual full Terabyte, or a Terabyte *after* formatting), and 0.0225BTC/TB each month afterwards. If you use SYS for the servers, you can still use OVH Enterprise Dedicated Boxes, and then download the plots over the internet. However, this connection will be limited to 500Mbps, and in actuality you're performance will waver between 300 and 400 if you are saturating multiple connections constantly.

Interestingly enough, Hetzner.de offers a 16TB dedicated server for 69 Eur including 19% VAT (so around $74/mo if you don't live in Germany, so you don't have to pay VAT). The processor in that box is capable of somewhere in the ballpark of 3600 nonces/minute more than likely, which would give you just over 1.18TB/day of plots. 16TB after formatting is 14.4TB-ish, so that would take the server around 14.4/1.18=12.2 days to create all the plots. Renting another dedicated server for plot generation seems impractical with Hetzner given the 200Mbps/connection, which may or may not also be the download speed.

Would people be interested in a service where you can buy pre-plotted external hard drives with a one-click miner?

why not cloud mining, just rent couple TB, for any period of time

Already providing that (0.045BTC/TB for setup + one month, then 0.0225BTC/TB a month after), but some people would probably prefer to outright own the hardware if they're looking for long-term BURST mining.

cool, i have a nice idea to mix PoC with PoW
first we do read plot as PoC, then we are idle right?
then during that idle time, we are generating more plots on the fly using GPU, just like on GPU PoW mining
thats like adding extra GB over your plot without need any disk space at all
but i am not sure how much GB, GPU can generate per seconds

I believe someone did a preliminary test and got the equivalent of 35GB per 4-minute period, so effectively 35GB per block on a high-end GPU, which drew somewhere around 200+ W at the wall.
