The BSHA3 project was apparently revealed last year, however it seems that the original developer of the coin has abandoned his work and a bit earlier this year it has been revived as a community supported project. BSHA3 is apparently the first crypto coin to use the SHA3d algorithm (like SHA3-256, but two iterations each time – in the spirit of Bitcoin’s SHA-256d). Other than the different algorithm the coin follows Bitcoin’s math with 50 BSHA3 coins per block, 10 minute block time and 21 million coins to be ever mined in total. The original chain relied on 2016 block difficulty adjustment as well, though that apparently caused it to get stuck at a point, so the new community fork at block 20418 with the new LWMA 3 difficulty algorithm was made available to fix the problem and restore the network.

There are already a number of mining pools available as well as few small exchanges that have listed the coin, though it seems that currently the mining is being dominated by a single Asian mining pool. There is a miner forked from ccminer for Nvidia GPUs available for the SHA3d algorithm available. Also the algorithm is already available for mining on FPGA devices as well, the HashAltcoin Blackminer F1 series do have support for SHA3d, though that does not bring that much advantage over a high-end GPU mining rig in terms of performance compared to ASICs for example.

The VeriBlock (VBK) project has recently launched its mainnet after a long period of testing and has just finished an IEO (Initial Exchange Offering) on the Bittrex exchange with all coins available in it sold in just about 10 seconds, so apparently there is quite the interest. VeriBlock’s technology supposedly delivers Bitcoin-level security to both new and established blockchain and cryptocurrency projects that may otherwise be vulnerable. This enables crypto coin development teams to focus on the innovative features and functionality of their project, rather than worrying about possible attacks.

VeriBlock is both PoW (Proof of Work) and PoP (Proof-of-Proof) coin, so you can mine it with your GPUs or spend some Bitcoins to PoP mine it. PoW miners are responsible for creating the blocks, providing the blockchain with intermediate consensus, and providing blockchains inheriting security through VeriBlock with a PoW-powered first line of defense. PoP miners are responsible for publishing a representation of the current state of the VeriBlock blockchain (and by proxy, all blockchains secured by VeriBlock) to Bitcoin in a fully DTTP manner.

Here we are going to focus on PoW mining (vBlake2 algorithm) with AMD and Nvidia GPUs, for both of which there are miners available and a number of pools. Do note that although there are no ASIC miners available currently for VBK, apparently there are FPGAs already available for mining VeriBlock with hashrate equal to that of about three rigs with GTX 1080 Ti (~18 GHS). Using the latest nodecore pow CUDA miner 0.3.11 on GeForce GTX 1080 Ti you can expect to get around 800 MHS hashrate per card, while AMD GPU owners with the latest AMD VeriBlock miner the expected hashrate per Radeon RX 580 8GB should be around 300 MHS (similar to the performance of GTX 1060 or P106 GPUs).

Since the nodecore miners are not yet that stable and fully optimized and sometimes pools are not very responsive, it is wise to use a simple restart script to make sure that your mining rigs won’t end up staying idle. Here is an example BAT file for Windows for the miner:

Veriblock.exe -o -u VHmonhpN6fiuyNdJgGnwsJ741CvkZY -p x
goto loop

The above BATCH file should be fine for the miner cleanly exiting after it encounters some error, however on some Windows systems we have seen the miner crashing with an error window popping up and the above code will not help in such cases. If you experience such instability, then you can add a bit more automation in order to restart the miner every 30 minutes (1800 seconds) with the example code below:

start Veriblock.exe -o -u VHmonhpN6fiuyNdJgGnwsJ741CvkZY -p x
timeout /t 1800
taskkill /f /im Veriblock.exe
goto loop

In order to mine VeriBlock (VBK) locally, since it is not yet available on an exchange (it should very soon be active on Bittrex after the IEO), you will need to install the latest VeriBlock Nodecore 0.4.1, sync the VBK blockchain and then run the Nodecore Wallet GUI 0.4.0 (Java-based platform independent GUI). There are a number of mining pools available already, though most of them are not very user friendly and it is hard to keep a rack on your mining rewards (it is easier to track them at the local wallet than on the mining pool) we would recommend that you try the as it is currently the most user-friendly visually and functionality wise VBK mining pool out there.

In order to check the current state of the VeriBlock (VBK) network…

The much anticipated Constantinople hardfork of Ethereum was initially planned for the middle of January, however a serious bug was discovered shortly before the time of the fork, so it was postponed. The new date for for Ethereum’s latest network hardfork system upgrade is around 27-28 February (end of the month) or more specifically at block number 7,280,000 (200,000 blocks later than the originally planed block). The hardfork will be in two parts, the first one will include all five EIPs (Ethereum Improvement Proposals) including the problematic EIP 1283, that was the reason to postpone the fork initially, and the second part will be used to remove the problematic EIP 1283. So after the Constantinople and Petersburg hardfork (the two parts we are talking about) the Ethereum network will have the following 4 EIPs active – 145, 1014, 1052 and 1234.

The improvements to the Ethereum network that the new hardfork will bring are numerous and they focus on improving salability, speed and efficiency of the blockchain. There is however a change that is also important to the economics of the Ethereum network and one that is especially important for miners. EIP 1234 is going to adjust the block reward, so after the fork miners will be getting just 2 ETH coins per block instead of the 3 ETH that they are getting at the moment. There isn’t much needed from you to do in order to be ready for the hardfork if you are using or mining Ether, just make sure you update any local wallet or client that you might be running. Also make sure to not make any transactions around the time of the hardfork in order to avoid any possible issues with delayed transactions and lost coins, though normally such problems are not very likely.
