Innosilicon has just announced their A9 ZMaster ASIC miner for the Equihash algorithm used by Zcash (ZEC) and other coins that is apparently capable of 50000 Sol/s with just 620W of power usage. This significantly outperforms the already announced Bitmain Antminer Z9 mini that should be offering 10 Ksol/s with 300W of power usage, but what makes us frown here is the price that Innosilicon wants to charge you for this device. The Innosilicon A9 ZMaster should cost $9999 USD with a PSU included even though the miner is apparently already available in limited quantity of 300 units with shipping scheduled to start on June 10th.

The A9 ZMaster is pretty expensive at least for batch 1, but apparently Innosilicon wants to beat Bitmain in releasing first a more powerful product, even in limited quantities and charging a pretty expensive price for the device. The second batch shipments are planned to start on August 15th, but by then the price should be significantly lower, especially considering that even Bitmain has already announced lower prices for its upcoming batches of the Z9 mini devices. Meanwhile we are probably soon going to see more ASIC manufacturers coming out with Equihash-based devices and this should further drive down prices, especially if there isn’t that much of a demand for the hardware with the current market conditions. The only problem with ASIC manufacturers trying to fuck up each other is that in the end the one often getting fucked up is usually the miner that buys one or the other of the devices…

It has been quite a while since we have seen a new update for the EWBF’s ZCash CUDA Miner that is one of the most used miners for Equihash-based coins on Nvidia GPUs. Interestingly enough the new version 0.3.4c was made available from Bitcoin Gold team members and via an update on the Bitcointalk thread for example. The updated EWBF’s ZCash CUDA Miner 0.3.4c promises an improvement of the mining speed of up to about 4% according to the release details, and we are actually seeing some slight performance increase based on our quick initial tests on GTX 1080 Ti, the new GTX 1070 Ti seem to benefit a bit more though.

Do note however that the performance increase may vary depending on the settings of your GPUs – TDP and clock settings, so feel free to try out this release and report your results. The new EWBF’s ZCash CUDA Miner 0.3.4c can be used to mine Bitcoin Gold or any other Equihash-based crypto coin, so this release is not intended ro limited only to BTG. Do note that it comes as a binary only release for Windows and Linux and there is a 2% developer fee that can be disabled with a parameter.

Earlier this month we have told you about the upcoming Bitcoin fork called Bitcoin Gold (BTG), but now just a couple of days before it actually happening there are much more details than at the initial announcement. There are still quite a few things that are not clear yet, but the user interest in this fork is growing and that is no wonder when users holding BTC will be getting the same amount of BTG on October 25 when the fork is expected to happen. Bitcoin Gold (BTG) forks at block 491407 where a snapshot of the Bitcoin blockchain will be made in order to credit Bitcoin holders with their Bitcoin Gold coins (the same amount of BTC they hold will be available in BTG). Bitcoin Gold promises replay protection, meaning that after the fork occurs the two networks will continue to function independently form each other and transactions of coins in one of them will not affect the other one.

One of the most interesting things about the new Bitcoin Gold (BTG) is that after forking from Bitcoin it will adopt a different mining algorithm and the chosen one is Equihash (the one introduced by ZCash), so the new coin will be mineable with video cards and not ASICs. This is what is essentially getting the attention of the many GPU miner out there that do not have any or just a little ASIC mining power. This is essentially eliminating the large ASIC mining farms from able to mine the coin as there are currently no known ASIC miners available for the Equihash algorithm, though it still cannot do anything about any large GPU mining farms and such also exist similar to the big ASIC mining farms. Still smaller GPU miners will be able to get into the mining of Bitcoin Gold (BTG) even with one video card, something they are not able to do with Bitcoin anymore.

There are still thing that are not clear about the fork such as what exchanges will support it and will credit the users holding Bitcoin with BTG after the fork. Some exchanges like HitBTC and Yobit, along with a few mining pools, have expressed their will to support Bitcoin Gold. The biggest and most used Bitcoin exchanges however are still to come out with official statements regarding the fork, so the best thing is to hold your Bitcoins in a local wallet where you have full control over the private key in order to be able to claim BTG coins after the fork. The exchanges are probably waiting to decide based on user interest as well as to see if the fork will be successful and problem free and come out with statements after that or their users may force them to.

The things that are not getting too much attention are mostly centered around the final specifications of the coin that are not very clear. For example the initial announcement mentioned tat the Bitcoin Gold (BTG) fork will have 16000 blocks premined with 12.5 BTG reward for each (200000 BTC coins) that will be sold to ICO investors, though the official project website does not talk about that at all. The fact that the BTG is capped at 21 Million coins just like Bitcoin and adopts 10 minute lock time, just like the original BTC, 12.5 BTG current coin reward?, halving every 4 years maybe? and so on… Since there have been already 16.6 Million BTC mined with a total of 21 that leaves less than 4.5 Million coins left to be mined over a very long period of time. All of these kinda leave a big question mark about the mining part of BTG and as we’ve explained there are still important things that are not very clear just a few days before the fork happening.
