CPU Mining MicroBitcoin (MBC) Using the Power2b Algorithm

7, May 2020

MicroBitcoin (MBC) has started as a hard fork from Bitcoin at block 525000 some time ago, but since its inception it has moved through some changes and it its current form it is interesting for everyone that has spare CPU resources for mining. MBC currently employs a CPU-only mining algorithm called power2b which is essentially a yespower modification which is replaces sha256 with blake2b. Power2b or yespower2b is a CPU friendly algorithm with no GPU miners available and no apparent FPGA or ASICs miners available. So while a single CPU might not earn a lot of MicroBitcoin per day it is still something useful to do instead of having your CPUs sitting idle, and if you want to exchange the bitcoin into dollars there are tools as the Bitcoin to paypal services which help a lot of this.

There are a number of miners available with support for the power2b (yespower2b) algorithm with two of them that seem the most reasonable to be used. The fastest one at the moment of all variants that we have tried is the latest SRBMiner-MULTI miner closed source miner that has a 0.85% development fee and the bit slower cpuminer-opt that is open source and has no development fee (supported by user donations). Feel free to try them both on your hardware and see what works better, though in all our tests SRBMiner-MULTI has proved to be faster even with the extra dev fee. It is worth noting that Intel CPUs do manage to perform significantly better compared to their AMD counterparts, in fact an Intel Core i7-6850K (6C-12T) processor manages to get about 1550 H/s while an AMD Ryzen 9 3900X (12C-24T) surprisingly manages to get us just about 1000 H/s. So AMD Ryzen CPU users might be willing to stay away from this algorithm and use their CPU mining resource for RandomX and RandomX variations where the Ryzen CPUs do manage to get significantly better results compared to most Intel processors.

There are a number of mining pools available with support for MicroBitcoin (MBC) mining, but the top ones you might give a try are HashPool, Rplant, Zergpool, Zpool and SkyPool. Zergpool and Zpool support the option to mine MBC and get paid in MBCg or to mine MBC and have the coins autoconverted and sent as their BTC value, the other pools are just for mining MBC coins. The preferred crypto exchange with support for MBC to trade coins is Stex that has two trading pairs – MBC/ETH and MBC/USDT.

MicroBitcoin (MBC) Rainforestv2 Optimized ccminer from SP

9, Oct 2019

If you might be interested in MicroBitcoin’s (MBC) Rainforestv2 mining on Nvidia GPUs you might want to check out the latest optimized spmod ccminer fork that offers significantly faster performance than the publicly available official version from djm34 (rfv2 ccminer). A quick test shows that SP’s optimized miner (closed source binary available for Windows only) is about 4 times faster than the public open source version from djm34 on a GTX 1080 Ti GPU, so significant boost in performance is to be expected on other Nvidia GPUs as well.

The only drawback with MBC is that it is currently listed on just 2 small exchanges with very little volume, although with a hashrate a few times faster than before there could be some profit to be made at least initially, so you might want to check it out. It has a huge market capitalization as the project is not so new, but the trading volume is pretty low at the moment. The cmminer SPMOD for rfv2 is compiled with CUDA 9.2 and is a 64-bit only binary for Windows, so make sure you meet the requirements to run the miner software.

Update: And very soon after the release of the miner MicroBitcoin (MBC) has successfully forked to a new algorithm – yespower2b… a CPU friendly one and not GPU mining oriented apparently, so the optimized miner was usable for just a couple of hours before the fork. MBC apparently needs to keep all their information channels more up to date about tings such as upcoming hard forks!
