Topic: Vertcoin - First Scrypt N | First Stealth Address - Privacy without mixer - page 685. (Read 1232692 times)

Glad to see another coin getting away from just scrypt. I'm definitely interested.

Finally, something that isn't a blatant cash-in. Eagerly waiting the white paper/tech specs.

Sure, I will upload it before tomorrow. Currently, we are testing in testnet to mark sure it can generate block and other things.

It shouldn't be hard. Will you disclosure algo some time before launch? I think the only thing required is CBlock::GetHash() code.

Nice!

Thank you for your recommendation.

400 years in the future, my garbage can should have 256 Gig of memory.

Goooood.

You should put that logo in the first post, and Vertcoin in big letters!

I will upload code to Github before tomorrow. Let's me test the code first

Actual programming? In MY coin?

This looks kinda cool. I'm gonna keep myself posted

Announcing Vertlet - Vertcoin Wallet for iOS
http://www.reddit.com/r/vertcoin/comments/28ugnu/announcing_vertlet_vertcoin_wallet_for_ios/

What is Vertcoin?

Vertcoin is a cryptographic currency, similar to Bitcoin and Litecoin, with one major difference.  As the forerunner of the digital currency movement, the original Bitcoin developers were unable to perceive all potential threats that would arise to challenge it's mission as a decentralized currency.  

Millions of dollars were spent by various companies to build application specific integrated circuit (ASIC)  computers in an attempt to monopolize mining.  These devices made it so GPUs and CPUs were no longer useful in the mining process.  As a result, the vast majority of Bitcoin mining and transactions would now be processed by large data centers that required hundreds of thousands, or millions of dollars in investment.

Now that Bitcoin computational power is handled almost entirely by large data centers, the currency has rapidly changed from a distributed, decentralized currency, to one that is much more centralized and vulnerable.  Companies such as Cex.io are routinely hitting 40% PoW computational power on a daily basis, and will soon be able to perform 51% attacks at will, if they so choose.

Due to the problems ASIC chips brought on the digital currency platform, a new currency, Litecoin was created.  Litecoin attempted to utilize the Scrypt hashing algorithm, which is more memory intensive than SHA256, to deter ASIC use.  As of January 2014, there are now Scrypt ASIC chips being deployed by the Chinese for mining.  So far, around 1000 Mhash of Gridseed ASIC chips have been brought online and used on the litecoin and middlecoin.com network.

The Chinese chips have not been released on the greater market at large, but eventually they will, and the same problems that SHA256 currency faces will come to the Litecoin and other Scrypt currency networks next.

Where does Vertcoin fit into this?

Scrypt was utilized by Litecoin to try and deter ASIC use because large memory requirements are the best way to try and make ASIC financially unfeasible.  Litecoin held out for a while, but the original memory requirements in the barebone litecoin distribution were just not high enough to lock out ASIC completely.  

Vertcoin has now been released as the logical evolution of Litecoin and introduces what's known as "Adaptive N-Factor".  The N-factor component of Scrypt determines how much memory is required to compute the hashing functions.  Vertcoin N-factor increases with time to stay one step ahead of any possible ASIC development.

For the long, foreseeable future, GPU computing will be the fastest method of computation for Vertcoin, but CPU computation will eventually make gains as N-factor increases.


Due to the large demand for having a more ASIC proof currency ( https://bitcointalksearch.org/topic/ltc-changing-the-litecoin-proof-of-work-function-to-avoid-asic-mining-359323 ), Vertcoin was created using Litecoin as a base, and has an adaptive N-factor applied based on the timestamp of blocks generated.  Instead of using a fixed value of 10, such as Litecoin does, the Vertcoin N-factor begins at 11 and gradually increases over time using the following schedule:

How to Mine
    
1)  GPU mine using CGminer modified for Vertcoin support (currently fastest method):
   1.  Windows Version https://vertcoin.org/downloads/vertminer-0.5.3.zip
   2.  Source code for both Windows and Linux https://github.com/Bufius/vertminer-gpu
 
   Build HOWTO for vertminer: https://vertcoin.org/gpu-miner-build-howto.html
 
   IMPORTANT: Please note that the Vertcoin algorithm requires different GPU settings, and that you will attain, at most, 50% of the normal hashrate that you would get mining a normal scrypt coin. Everyone else will also of course have at most half their normal hashrate, so you will remain equally competitive and mine the same "slice of the pie" as you normally would.
    In particular, you will need a --thread-concurrency setting of around 70% your normal setting. There is a GPU settings thread at https://bitcointalksearch.org/topic/the-big-vtc-vertcoin-settings-thread-416572.new#new that may help with setup, and if you are setting up on a GPU type that no-one has posted settings for yet, it would be appreciated if you would post your GPU type, settings and hashrate achieved in that thread.

2)  GPU mine using CUDAminer modified for Vertcoin support
   1.  Windows 64 bit Version https://vertcoin.org/downloads/CudaminerWin64.zip
   2.  Source code for both Windows and Linux https://github.com/cbuchner1/CudaMiner
   3.  OSx Build of CUDAMiner https://vertcoin.org/downloads/CudaminerOSx-Aleks_N.zip
        Requirement : CUDA toolkit 5.5 and "--algo=scrypt:2048" command
    
3)  CPU mine using CGminer or CPUminer modified for Vertcoin
   1. Windows version https://www.amazon.com/clouddrive/share?s=D_fMD9YnSuMm5b8Ldi-jiA
   2. Source https://github.com/Bufius/cpuminer-vert
    
4)  CPU mine with wallet (currently slowest method):  
   1. Open Vertcoin Wallet
   2. Choose Help
   3. Select Debug window
   4. Select Console
   5. Type “setgenerate true ”
   6.  type  "getmininginfo" to see hashrate
