LBRY is a new blockchain-based decentralized content-sharing platform geared towards content creators (filmmakers, musicians, writers, or software developers) who want to have full control over their own work. There are no ads, no corporate censors, and LBRY takes no portion of your income as a content creator and consumers can also benefit as there is finally an alternative to the big media stores. It has been in development for a while, but just recently it was launched in Beta, though you still need to request an invitation in order to be able to get early access. The LBRY network uses its own crypto token called LBRY Credits (LBC) that you can already mine, even if you still have not received your early access to the platform for the moment (while waiting to get it). Not to mention that there is also an operational market for LBRY Credits on Bittrex, so that you can also trade them when you mine some.

Initially LBRY Credits (LBC) mining was only possible with a CPU miner released by bitbandi (source), with compiled Windows binaries by the miner author available here. The CPU miner however is not very useful anymore as a GPU miner has been released shortly after in the form of an sgminer 5.4.0 forked to support the algorithm used by LBRY (source) that is much faster, you can find a downloadable 64-bit Windows binary release below that you can try if you are interested. Do note that the sgminer for LBRY currently works only on AMD GPUs, but with this big interest we are hopefully also going to soon see a GPU miner for Nvidia GPUs as well. There are already two mining pools available with more probably to follow, the first one was made available by Suprnova (not yet updated for the difficulty adjustment of the GPU miner and the GPU miner can provide lower hashrate as a result) and the second one is by Pool.mn that already adjusts difficulty for the significantly higher hashrate of GPUs.

Wolf Has Publicly Released OpenCL Optimized Kernels

9 Jul
2016

wolf-optimized-kernels

Released under the MIT license for educational purposes, the collected kernels of Wolf are now available on GitHub for public download. The list includes optimized OpenCL kernels for a number of crypto algorithms: AES, Blake, BMW, CubeHash, Echo, Fugue, Groestl, Hamsi, JH, Luffa, Shabal, Shavite, Simd, Skein and Whirlpool. The OpenCL kernels need to be integrated into a miner like sgminer and some extra tweaking might be required, so they are more interesting for developers that are willing to optimize the performance of their own miners. They are even useful in understanding how some optimizations work and may be applied to other algorithms as well, so a good learning tool, at least for developers. If you find something useful or just want to send a tip to Wolf you can do so to his BTC address here: 1WoLFumNUvjCgaCyjFzvFrbGfDddYrKNR.

Siacoin (SC) Open Mining Pool Now Available from Nanopool

Siacoin (SC) has been picking up recently and there have been talks about privet mining pools available, but the good news is that you can already GPU mine the SIA crypto tokens that are powering a decentralized storage network in an open pool. The open Siacoin mining pool already available is sia.nanopool.org and you can join it and start mining in no time. The pool does not need a registration, all you need to have is a wallet address – generate one with a SIA local wallet or use an exchange generated wallet from Poloniex or Yunbi. You can download the GPU miner for Siacoin written in in Go for pool mining (source) compiled and ready to be used from the link below (64-bit release for Windows) or use the latest Claymore Dual Miner that brings support for Dual Mining Ethereum along with Decred or Siacoin as a second coin (previously only Decred was available for dual mining).

The SIA Nanopool pool uses PPLNS payout scheme, has a fee of 2%, executes payouts once a day with a minimum payout currently set at 5000 Siacoins. Out test with the Siacoin Go miner for Siacoin shows about 1116 MHS as a hashrate for a single Radeon R9 290X GPU without overclocking, so you can have that number as a reference. The miner also works on Nvidia GPUs (it is still using OpenCL, not CUDA), as a reference number you can expect to get about 803 MHS from a GTX 970, do note however that for Nvidia-based mining rigs the go miner is the only choice as the Claymore dual miner is only for AMD GPUs. If you want to focus on mining Ethereum and mine Siacoin as a secondary coin and have AMD GPU mining rigs, then you can also try the latest Claymore dual miner version 5.0 that now gives you the choice for mine Decred or Siacoin besides Ethereum. Please report your hashrate and success in running the miner on different hardware, both AMD and Nvidia-based GPUs, in the comments below. should you decide to try mining Siacoin.
