One of the key new features of the recently launched Shift (SHF) altcoin, the first one forked from Ethereum, was the availability of a GUI wallet – essentially a simple graphical frontend for the shift client software. This GUI is also available and was probably originally developed for Ethereum as the project is called Etherwall (source), written by one of the developers of the Shift team. Etherwall is also available as a compiled binary for Linux, Mac OS X and Windows and you can download these from the official website instead of having to compile the code from source. Do note that Etherwall requires geth 1.0.2 or newer to be installed and running in order for the wallet GUI to connect to it and function. What Etherwall does is provide a simple and easy to use basic functionality for managing your Ethereum accounts, check what balance you have as well as to send transactions. It is easier and much more user friendly for people that are not into working with console commands to do even simple things like checking a balance or sending some coins, so you might want to check it out.

It seems that there was another issue with the Go Ethereum client (geth) that was causing the difficulty of the Ethereum network to increase at high pace even when the network hashrate is not actually increasing. The problem has been identified and if you are using the geth client for solo mining or as a local wallet you should upgrade to the latest geth version 1.1.2 (source). It is more important however that the Ethereum mining pools update to the latest geth client as apparently this is the preferred client used by the pools and not the alternative cpp-ethereum that is not affected. After the fix has been deployed we should start seeing the Ethereum network difficulty to start to normalize. We have provided the updated Windows binary of geth 1.1.2 in our package intended for getting started with Ethereum. If you haven’t checked our guides for Ethereum solo mining and Ethereum pool mining on Windows using geth and ethminer, as well as our guide on Ethereum mining with cpp-ethereum.

Do note that if you are currently mining for the Shift (SHF) – the first altcoin that has been forked from Ethereum, then you should also update to the latest client. The Shift client software is based on the Go Ethereum client code, so it is affected by the same difficulty issue as Ethereum was, but this has been addressed in their latest update as well.

A new update in the form of a new Windows binary release compiled from the latest Git source code of the ccMiner 1.5.63-git SP-MOD fork of the Nvidia GPU miner optimized for the latest Maxwell-based video cards by SP (source). The latest version includes more fixes and some slight hashrate improvements. Do note that the SP-MOD fork of ccMiner is designed for Nvidia Maxwell GPUs such as the already available GTX 750, 750 Ti as well as the newer GTX 960, GTX 970, GTX 980 and GTX 980 Ti and GTX Titan X. The Windows binary release we have made available here is with support for Compute 5.0 and Compute 5.2 GPUs or with other words only for Maxwell-based cards compiled with CUDA 6.5 and VS2013.

Update: We have compiled and updated the binary with the latest code changes that include significant increase in performance for BlakeCoin – up to about 70% increase in the hashrate. As an example with GTX 980 Ti the older ccMiner could get up about 2.033 GHS and with the updated version the performance we get now form the same GPU is 3.531 GHS, a GTX 950 GPU is up from about 677 MHS to 1.17 GHS, so the increase is very significant. Due to the high difficulty that BlakeCoin (BLC) has because of it being merge mined with multiple other coins this performance increase might actually make it interesting to actually mine it with Nvidia GPUs.
