The ccMiner software miner for Nvidia GPUs has received an update to version 0.7 (source) adding support for Jackpotcoin and Myriad-Groestl. The new official release contains multiple versions for various GPUs, but do note that currently older Compute 2.0 hardware is not yet supported. Our test has shown a hashrate of about 7-7.2 MHS for mining Jackpotcoin on a single GTX 780 Ti GPU, so the performance you can expect mining JPC on Nvidia hardware is better than what the AMD GPU miner for JPC can currently provide.

Jackpotcoin (JPC) is a new crypto coin that uses a new hash algorithm called Jackpot Hashing Algorithm (JHA) and thus requires special miner software in order to be mined. The coin has a CPU miner available, but we are going to be skipping this one as there is also a GPU miner available already. The OpenCL miner for Jackpotcoin is based on the official sph-sgminer, but since the official release is not yet available with JPC support you need to use the fork for Jackpotcoin for now (source code). we have compiled a windows binary from the latest source that you can download below, our test on a single Radeon R9 280X GPU showed a performance of about 2.2-2.3 MHS mining Jackpotcoin, so it seems that Nvidia is currently the better choice for mining JPC on the GPU.

JackpotCoin (JPC) JHA-based cryptocoin

JackpotCoin (JPC) is a truly innovative coin with many new features. New hash algorithm called Jackpot Hashing Algorithm (JHA) uses variable hashing round with SHA3, Blake, Grøstl, JH, Skein – requiring a special miner to be mined. It is permanently ASIC-resist and with increased security and reduced loads. It saves power as compared to the conventional hash algorithms. It support both CPU mining and GPU mining. 2nd Generation of PoW/PoS coin. JackpotCoin PoW/PoS difficulty retargets are independent, with faster PoS block target to ensure faster transactions, yet different PoW block target does not generate too many coins to flood the market. Support true random superblocks. The true randomness eliminates the possibility that super-powerful mining pools (especially multipools) can profit from the pseudo-randomness based on the previous block hash. Multipools and cheaters cannot take any advantage of the true randomness of the superblock in JackpotCoin.

JackpotCoin offers a Jackpot reward. The superblock reward depends on the distance from last superblock reward. The longer the distance, the bigger the reward will be. The Jackpot starts at 10x the normal payout, increases in a parabolic way (thus non-linear way) with the distance to last super block: at 3.5 days, it will be at 100x the normal payment, and if goes to 7 days without triggering the superblock, the jackpot will be increased to 1000x the normal payout. The superblock is triggered in true random fashion with average 3.5 days per superblock. The JackpotCoin Client provides a special function to query the current jackpot size, and people can see it increases rapidly with time if not triggered.
