The LBRY Project and the LBRY Credits (LBC) crypto token used by it is reaching an important milestone for the miners and this is a moment when you might want to pay attention to. The block reward when mining LBRY Credits was constantly increasing in size from 1 to the maximum of 500 LBC over the course of a few months and the reward schedule is such that after peaking at 500 LBC the block reward will start to decrease. This is a good opportunity to catch the peak and mine some coins, especially if you are using Nvidia GPUs where you should give a try of the latest ccMiner from tpruvot. Do note that the project is still in invite mode beta, but there is no problem for you to mine LBC tokens and even trade them on the open market, alternatively you can just buy some of course.

Earlier this month the project has received some serious funding from a venture capital and that is here to show that the potential for LBRY is there and it is really promising idea that only needs to get implemented properly to really have a serious effect on the status quo. If that will happen is yet to be seen, but the project developers promise to open up the beta app by the end of this year (still in invite only mode) – and going to full product release in 2017. The 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 that LBRY promises can be a game changer, so make sure you don’t miss the train on this one. Again, there are no guarantees, but the potential is there, so why not give it a try and see for yourself.

A quick update with a new Windows binary compiled from the latest ccMiner 1.8.3-git fork from tpruvot (source) with some improvement in the LBRY mining performance based on Alexis Provos work and basic implementation of the Veltor algorithm with some other minor fixes. The release below includes two versions of ccMiner, one is 32-bit binary for Windows that is compiled with CUDA 7.5 and with support for Compute 2.0 or newer Nvidia GPUs, and another that is 64-bit Windows binary compiled with CUDA 7.5 for Compute 3.5 or newer Nvidia GPUs. We have tried compiling the 32-bit version of ccminer with CUDA 6.5, but the resulting version did have some issues with LBRY, so we have compiled with 7.5 as well and it worked fine.

Another update in the form of a Windows binary compiled from the latest cpuminer-opt (source) CPU miner with added optimizations for many algorithms using the AES-NI instruction set (also works on older SSE2 capable CPUs). Up until recently the cpuminer-opt was available only for Linux users, but starting from version 3.3 there is also Windows support and we have compiled 64-bit binaries of the miner for Windows for the latest released version 3.3.8. The latest update brings some performance improvements such as blake2s with about 10% higher hashrate, support for new algorithms such as LBRY, Whirlpool and WhirlpoolX as well as fixed Skein2 that was apparently broken in the previous version.

In the archive below you can find multiple executable files that are compiled for different CPU architectures that support AES-NI instructions, so you are welcome to try them to see what works best for you. If your processor does not support AES-NI (CPUS introduced 5 or more years ago), then you might want to use the cpuminer-sse2.exe binary. The default cpuminer.exe is compiled for Intel Westmere, the first Intel architecture that has support for the AES-NI instruction set and cpuminer-amd.exe is bdver1 which should work on all AMD processors with AES-NI support. If you have a more recent Intel Sandybridge, Ivybridge, Haswell or Broadwell-based processor you can try the respective binary to see if that will squeeze some extra performance, or you can compile directly on your PC with the native instruction set supported by your CPU.
