Braiins OS Wolfram With AsicBoost Support for All S9 ASIC Miners

26, Oct 2018

While we are still waiting Bitmain to release AsicBoost support for all of its Antminer S9 variations, Braiins OS Wolfram was made available from the Braiins team. This new release of the Braiins opensource OS for Bitcoin ASIC miners comes with support for all Antminer S9 variants and adds support for AsicBoost as well, it also works on DragonMint T1 (only the variant with Xilinx based control boards). Aside from AsicBoost support on S9 mining hardware, by using the Braiins OS Wolfram you also get the ability to change the clock frequency and voltage for the miners on per hashboard basis, so more tweaking options.

Braiins OS uses over (version-rolling) AsicBoost in accordance with BIP310. For Antminer S9, this is currently done using the bitstream provided by the manufacturer, but the goal is to switch to a custom open-source bitstream as soon as possible. All Antminer S9 models (S9, S9i, S9j) are supported, however, the amount of possible variations is rather high, so for this reason it is recommend to test an SD card image first on a single device and once you are confident that the firmware operates according to your expectations, you can apply factory transitional firmware images. Then you can start tweaking the voltage and frequency settings to utilize the extra power savings that you should get of about %13 thanks o the use of AsicBoost.

Braiins OS, An Opensource Operating System for ASIC Miners

3, Oct 2018

Braiins is the company behind one of the oldest and most trusted Bitcoin mining pools – Slush Pool, and they something new and interesting to show – an alternative opensource operating system for Bitcoin ASIC miners in the form of what they call Braiins OS. It is the very first fully open-source, Linux-based operating system for cryptocurrency embedded devices with the initial release targeted on mining devices and more specifically Bitcoin ASIC miners. Braiins OS has been developed for two primary reasons: to be open-source and have no “hidden features” and to work stable following standards without issues.

The first release includes images for Antminer S9 and DragonMint T1 (only the variant with Xilinx based control boards). Braiins OS is currently mostly on par with the official vendor firmware at this point. It monitors the hardware and its working conditions, handles errors and provides various performance data, but more features will be introduced making it a more interesting alternative. Most importantly possible performance improvements are being looked into as that would probably please the miners the most. The Braiins OS is intended to integrate flawlessly with the Slush Pool, but it should be just fine with any other alternative pool for SHA256 mining, so you are not going to be limited in where to mine with it.

Be aware that Braiins OS is still in alpha stage and has not been tested on a large scale yet, so you might want to start by deploying to single miner to give it a go before deciding to deploy on larger scale!

FutureBit Project Apollo: Bringing ASIC Mining Back to the Home Miner

31, Aug 2018

An interesting new project from the developer of the FutureBit Moonlander and FutureBit Moonlander 2 USB Litecoin ASIC miners jstefanop called FutureBit Project Apollo. The new device called the FutureBit Apollo LTC is trying to be the world’s most efficient Scrypt ASIC miner, using WiFi and actually being silent… and if it is available at a good price point we are sold. It is targeted at home miners that want to get into mining and/or play around with ASIC miners and not large scale mining operations and mining farms, though it might be interesting for bigger miners as well thanks to the promising specifications announced.

FutureBit Apollo LTC miner Prototype Specifications:
– Compact Stand-alone Pod Style Miner (4x6x4in).
– Very wide range of operation modes with preset ECO (quiet) mode and TURBO mode.
– 100-140+ MH/s of Scrypt performance per miner.
– Industry leading 1W/MH in ECO mode, and 1.4W/MH for TURBO (100-200 watts).
– Powered by a fully integrated Quad-Core A7 ARM based controller.
– First miner to be fully controlled over wifi, only cable needed is power! (this will be a Beta feature on launch..backup ethernet port is available as well).
– Clocks and Voltage is fully customizable by user with easy to use interface (no more pots!).
– Industry leading 97% efficiency 12v power-stage, with 27 ASIC chips powered in a 3×9 parallel/serial power arrangement.
– Custom designed cold forged hexagonal pin heatsink with leading thermal performance for the quietest ASIC miner in operation!
– 2k-6k PWM High Static Pressure Dual Ball Bearing Fan with automatic thermal management with onboard temperature sensor.
– Controlled via local connection on a web browser similar to antminers. You can simply set it up via smartphone browser. No crazy driver installs, hard to use miner software or scripts needed.
– Two Six Pin PCIE power connectors for wide-range of power draw (only one is needed in ECO mode).
– New future platform features including full-node/peer to peer fully decentralize mining, full stand-alone solo mining, cloud/app based controls and more in development.

According to jstefanop the device is ready for mass production and it will be available in pre-order batches just like the previous Moonlanders. The first batch will be a VERY limited run (under 1k units) in order to fix any production issues with expected price range of $200-300 USD (it is not easy to beat large scale manufacturing in China) with better price and better efficiency. The first batch will probably be available for October delivery to people that pre-order the device in a first come first served basis. All of the initial sales for the Futurebit Apollo miner will be handled through the official Futurebit project website, though later batches will probably be available through resellers.
