GPU Miner for Heavycoin is Possible and is Being Worked On

14, Mar 2014

heavycoin-crypto-cyrrency

Heavycoin (HVC) is a recently launched crypto coin that can be mined only with the CPU, but apparently it is not impossible for a GPU miner to be created for it as well like with many other coins that started as CPU mining only. The key of the coin being “CPU only” is the use of multiple crypto algorithms – SHA-256, Keccak-512, Grøestl-512, BLAKE-512. But if you port all of them on the GPU you can achieve considerable speedup than what is possible with the CPU only mining, however for the moment there is no GPU miner available for HVC. The author of CudaMiner has reported some success already, note what he has posted in the bitcointalk forum about his work on a GPU miner for HVC (not CudaMiner, but a separate project):

we’ve accelerated 4 out of 5 hashing algos for HVC, but the last one (Groestl) is causing us a bit of trouble. Our first port is actually slower than the CPU – at least on my system.

Running Groestl on CPU and the rest on GPU I am getting an 800% performance boost vs. running the CPU alone.
Multiple CPU threads can even share a GPU ;)

Note that overall HVC is *not* CPU-only. They really need to change their advertising, and change it quickly. Whatever they did to SHA256 to turn it into a “GPU and ASIC resistant” HEFTY1 algorithm – it didn’t work as they intended.

Heavycoin (HVC) HEFTY1 based cryptocoin

8, Mar 2014

heavycoin-crypto-cyrrency

Heavycoin (HVC) is a HEFTY1 CPU-only Ultra-secure new crypto currency with decentralized block reward voting. Get ready to mine, mining starts on March 8th 12:00 UTC! Heavycoin has the potential to achieve massive adoption and become a wide-reaching crypto-currency. With a strong community behind it, Heavycoin could even challenge Litecoin for position number two next to Bitcoin. With this in mind, the Heavycoin launch is taking place in multiple stages to encourage a diverse body of early adopters and stakeholders. Heavycoin will also leverage multiple launch strategies for maximum impact.

Heavycoin mining will open up a new dynamic because of decentralized block reward voting. Miners who are greedy and have little stake could vote for the maximum block reward of 1024. However, this will increase the supply of Heavycoin and decrease their profits. Other miners, who are not greedy, or who already have a sufficient stake, might vote for a lower block reward — even zero — in order to decrease the supply and to slow the minting rate. Either way, this is going to be interesting!

Intially Heavycoin starts with a zero block reward. The very first miners will have the first opportunity to solve blocks and vote on what the first democratically selected block reward should be. The first 100 blocks (3.3 hours) will decide the starting block reward. From then on, block reward voting will continue, but the votes are counted and averaged every 3600 blocks (5 days).

Heavycoin is configured to mine and vote by default, with a default vote of 512 HVC. If you want to change your block reward vote then see “How to vote” section of our website. Otherwise, to disable voting then see “How to mine”. When mining is enabled, every time you mine a block your wallet will automatically cast a block reward vote. The Heavycoin network automatically averages these votes every 5 days (3600 blocks) and sets the new block reward accordingly. The block reward is the average of all 3600 votes over the previous voting period rounded to the nearest integer.

Protoshare Mining Test at 1GH PTS Mining Pool

31, Jan 2014

1gh-pts-mining-profitability

After trying out PTS mining at ypool we have also decided to try out another Protoshares mining pool with CPU mining to see if we are going to get better results with the Round-Based Pay Per Share (RBPPS) payment system and the lower 3.5% fee that the 1GH PTS mining pool has. We’ve been testing the pool with GPU miners lately, however for the last 24 hours we tested only with CPU miners to see what profit we are going to get.

The two CPUs we’ve used for mining are:
– Intel Core i5 2500K Quad Core 3.3 GHz
– AMD Phenom II X6 1100T Six Core 3.3 GHz

The 1GH pool we used for PTS mining has:
– 3.5% fee

The total earnings for 24 hour period (confirmed + unconfirmed):
– 0.1169 PTS

The value of the Protoshares mined for 24 hours is as follows:
– 0.00173806 BTC
– ~$1.38 USD

The profit we got from the 1GH PTS mining pool was a bit higher than the one we’ve managed to get for 24 hours at ypool, however the difference in USD is also affected by the BTC/USD and PTS/BTC exchange rates. What is clear however is the fact that there is not much point in mining Protoshares (PTS) with CPU at the moment, if you plan on mining Protoshares then you need to think about going for GPU mining. The 1GH Protoshares mining pool has a very good performing GPU miner that works on both AMD graphics and Nvidia graphics very well. Furthermore the 1GH pool has another advantage over ypool and that s the fact that this pool sends automatically your earnings as long as they are over 0.1 PTS confirmed and in ypool the minimum is 1 PTS.
