The RavenCoin (RVN) project is up for another fork sometime in April that will change once more the Proof of Work mining algorithm used in order to fend off FPGA and ASIC miners specifically and allow GPU miners to get back to mining the coin. The first fork to change the mining algorithm in October last year changed the initial algo to a new X16Rv2 and while that did drive off ASIC and FPGA miners for a while off the network, it did not help that much on the long run as apparently specialized mining hardware was quickly adapted to the new algorithm. This time the change in the algorithm is more drastic and should make sure that GPU mining on a level playing field for both AMD and Nvidia GPU miners is available for long…

The new algorithm that RVN will be adopting is called KAWPOW and is a derivative of ProgPOW with parameters specific for Ravencoin. The fork is planned for sometime in April, but a specific block time and expected date is not yet chosen. Meanwhile you are welcome to test the new dedicated miner called kawpowminer software that currently only supports mining the new algorithm and you can test it on the RavenCoin testnet using the MinerMore mining pool to make sure you are ready for the fork.

RavenCoin KAWPOW testnet pool:
kawpowminer -U -P stratum+tcp://WALLET.worker@rvnt.minermore.com:4505

The miner is currently available for both Windows and Linux operating systems, though apparently there is not yet official OpenCL binary for Windows, only CUDA. Since the binary releases do not include the required Nvidia CUDA 10.2 libraries you would also need to have the latest Nvidia CUDA Toolkit installed (or at least the runtime libraries from it). Other popular mining software would most likely add the required support for the new algorithm soon before or after the fork to the new algorithm occurs.

Expected performance on stock settings:
– GTX 1050Ti: ~5+ MH/s
– GTX 1060: ~9.5 MH/s
– GTX 1070: ~14 MH/s
– GTX 1070Ti: ~14 MH/s
– GTX 1080Ti: ~24.5 MH/s

We remind you that unlike with Ethash, PROGPOW does not favor lower-end AMD GPUs as it is not so much memory dependent, thus a lower-end AMD GPU will perform similarly to the same level of Nvidia GPU and a higher-end AMD GPU like a similar class Nvidia GPU when using the new KAWPOW algorithm!

Back in October Ravencoin (RVN) forked to X16Rv2 as a means to drive away the ASIC miners for the X16R algorithm it previously used. The new algorithm X16Rv2 has helped lower the hashrate and make RVN mining prfotable for mining with GPUs for a bit, but now it seems we are getting back on the road to ASIC miners in the near future for the new algo. The X16Rv2 is apparently getting bitstreams for FPGA miners like the BittWare CVP-13 FPGA with 240 MH/s cited hashrate for the initial release… this is faster than 6x GTX 1080 Ti GPU mining rig with a third of the power usage. The only catch is that the CVP-13 FPGA Cryptocurrency Mining Board is pretty expensive, but unlike ASICs it can be used for a number of algorithms and with future bitstream updates can be much more futureproof. Of course the next step is new ASIC miners coming in the near future for the new X16Rv2 algorithm with Ravencoin getting quite a lot of attention from users.

A few days have already passed since the fork of Ravencoin (RVN) on October 1st that included a change in the PoW algorithm used for mining – from X16R to X16Rv2. As you can see from the network hashrate graph above from Ravencoin Statistics it is still lower than prior he spike from end of Agust/beginning of September. This means that the fork has effectively affected the usage of what seems to be ASIC miners that went operational at the end of August that resulted in more than doubling the hahsrate in just a few days of time. Another sign that there are no more ASIC miners mining and dumping coins is the fairly stable price of RVN after the fork with no selling pressure on exchanges from such miners trying to get rid go the mined coins. As a result RVN is among the most profitable coins to mine for Nvidia GPUs at the moment after the fork, even if the profit is nothing to brag about, pretty much all the rest of the altcoins are doing worse…
