The latest Bminer 15.5.0 comes with another interesting dual-mining feature that has attracted our attention, namely dual-mining Ethereum (ETH) and VeriBlock (VBK), meaning that you can mine any Ethash coin together with the vBlake2 algorithm used by VBK. The new version also comes with improved performance of the Cuckatoo31 algorithm and added parameter
-version to output the current miner version and exit.
What we were most interested in the new version was the support for VBK (no standalone support for the algorithm yet), so only dual mining Ethash and VBK for now. We wanted to see what performance we can expect in this dual mode from VBK as we already know what to expect regarding Ethash hashrate. Unfortunately it seems that VBK support really does need some more work as the miner is somewhat unstable when dual mining and crashes from time to time and results are also erratic. With OhGodAnETHlargementPill running we were not getting any accepted shares for VBK, only stales, and with the Pill software not running it seems that VBlake2 shares are properly submitted. It is hard to understand however what is the exact hashrate for each of the two algorithms when dual mining, so more work is required on that new feature apparently.
We remind you that that Bminer is a closed source Nvidia GPU miner available for Linux and Windows in the form of pre-compiled binaries and that there is a 2% development fee for Grin, Beam, Bytom (BTM), Equihash and Zhash coins, 0.65% for Ethash and 1.3% for dual mining Ethash and Blake.
