[ANN] [HVC] Heavycoin - Ultra-secure, Decentralized Block Reward Voting, Fast

[MrE78]

Remember folks arbitrage is your friend and you can sometimes buy some cheap HVC, the dev didn't list us on the front page as most developers would do when exchanges take their coin but we've been serving up HVC since launch and appreciate your support.

Both www.cryptoaltex.com and atomic-trade.com were here for you since launch, so bounce the HVC back and forth between the exchanges and grab yourself more of em those heavy suckers.

I think the dev is just snubbing you and www.atomic-trade.com

I know BryonP from AT was in contact with the dev but, didn't get far. But thats fine you are right about arbing, I made a nice chuck overall quick swapping, first round got screwed from slow withdrawal but thats life sometimes.

Guys let vote for 1 block reward!

Been doing that since start.

[Kooness]

good job!

1gh is getting all the blocks. If you don't spread the hashrate we are fucked

Getting stratum to work properly under windows in heavycoinpool.com (or elsewhere) is priority number one. This has been an issue since the first day. Stratum in 1gh works perfect for different platforms. I don't understand what's taking so long to have a good alternative for mass adoption.

On my home pc i7 3770K getting 200khash/sec (overcklocked to 4,4Mhz)

why mine i5 2500 k OC to 4400 get only 66k?

Isn't 1gh a version of p2pool? I don't have a worker and I am using my hvc address....

maybe because i'm mining from the wallet?

i have about the same oc of your cpu, yeah mine isn't the 3770k, but it's not a bad cpu also...

it is easy to overclock a cpu?

[Amph]

it is easy to overclock a cpu?

yeah, but not so easy to make it stable, you need to go to the bios settings

[hartvercoint]

I'm sorry for not crawling the entire thread,

can anyone link me windows binaries of the cpuminer fork?

sorry guys, got it!

I mean if i only overclocked it a tad would that be stable enough do you reckon?

its 2x12 core xeons I want to overclock

Are they in a motherboard where you can overclock? You can forget about it if they're in a server chassis. You'd need something like an EVGA SR-2.

they are just in a full tower not rack mountable server or anything like that.

What motherboard? I'm pretty sure the only dual LGA 1366 motherboard out there that allows for overclocking is the EVGA SR-2. I'm running a pair of X5650s in mine at 3.8GHz.

Someone private messaged me to check out HeavyCoin.

Sorry I realize this post will make people angry at me. I am usually the messenger who brings technical reality which is usually bad news because most coin developers are not competent.

Innovations and contributions

• HEFTY1 - a cryptographic hash function for CPU-only proof-of-work with a small memory footprint

Insufficient technical details. From what I read about their claim of SIMD as an issue. I think they fail to understand the nature of the GPU advantage.

• Ultra-secure hashing - a secure strategy for using multiple cryptographic hash functions

From the Github page:

Q: Doesn't Quarkcoin already implement multiple cryptographic hash functions?

A: Yes, but without increasing security against collisions. Quarkcoin (and its many clones) actually implement multiple hash functions as a simple chain of function compositions
Quark(x) = ... SKEIN512(KECCAK512( ... BMW512(BLAKE512(x))))

where ... contains additional hash function compositions using JH-512, Keccak-512, BMW-512, BLAKE-512, SKEIN-512 or Grøestl-512, which are randomly selected based on the 4th bit of previous hash outputs.

The problem is that, due to Quarkcoin's simple use of function compositions, if BLAKE512(x) has collisions, then so does BMW512(BLAKE512(x)) and SKEIN512(KECCAK512(... and so on, until we reach Quark(x), which also has collisions. Similarly, if SKEIN-512 or Grøestl-512 have collisions, then so does Quark(x). Simply put, if there's a collision attack or second-preimage attack for BLAKE-512(x), then Quark(x) is cracked.

Bullshit. Changing even one input bit to a hash should randomize all the output bits. Cracking any combinations of the hashes in the chain of hashes does not increase the risk of collisions for those in the chain that were not cracked.

This kind of silly mistake proves the developers are technically incompetent.

Whereas their "improvement" is worse in the sense that it takes 3 cracks to make it very insecure and 2 cracks to make it perhaps insecure, whereas with Quark it takes 4 cracks.

Q: How does Heavycoin implement multiple cryptographic hash functions?

A: Heavycoin takes 64 bits from the output of each of 4 well-known cryptographic hash functions (SHA-256, Keccak-512, Grøestl-512 and BLAKE-512) and interleaves these bits into a combined 256-bit hash that is more resistant against collisions and second-preimage attacks.

Hope you realize that 2^64 is crackable with a server farm. If 3 of the 4 are cracked, then the 4th is useless in Heavy's design.

• Temporal Retargeting - multipool protection that goes beyond Kimoto Gravity Well
• Decentralized Block Reward Voting - the mining schedule and money supply are democratically decided (total supply is still bounded to 128M)

Oh great let the early investors decide to make coins even more rare. This will be a very good experiment to show why democracy is a power vacuum.

Thanks for the supportive posts guys.  Having the coin on more than one exchange helps keep a stable price.  If it's only listed in one spot it can be manipulated way to easily and any good coin has a stable, steady rising price or a slight up and down and wave on the charts. 

I hope HVC goes far and that all your investment dreams come true.  Continue to support CryptoALTeX and Atomic-trade as atomic-trade has already gone through the legal hurdles herein the USA to make sure they are running a legit business.  CryptoALTeX is also an LLC and we are currently working on getting registered with FICEN and the other steps we need to take in order to bring you a proper business that meets all legal standards.

Nope. You can't overclock on the Z9PE-D16. You can on the Z9PE-D8 WS, though. You can't get much of an overclock on the E5s though, maybe 100-200MHz. I have a pair of E5-2670 V2s in mine.

2x2697s here, cheers for the help dude, they are running at 2.7 now, shame I cant get even a little bit more from them in the bios?
