Recently the NiceHash platform has made available a new feature that they call Solo Mining with “Catch the Block” and we have decided to try our luck and see if we can manage to hit a block and get the full block reward. NiceHash have made this new feature very easy to be used, almost like buying lottery tickets and testing your luck hitting a big reward. What you do here is buy a package of hashing power from their platform that will be used for mining a certain crypto coin for some time, and if you validate a block with it then you get the full block reward. All you need to do is choose a mining package (pay for it with Bitcoin) and wait for it to finish mining and see if you were lucky enough or not to hit a block and get a nice reward. Currently mining Bitcoin (BTC), Bitcoin Cash (BCH), ZCash (ZEC) and Dogecoin (DOGE) are supported by thins new mining feature and you have a couple of different mining packages that you can choose from…

In order to be able to use the Solo Mining mode you must first have an account at NiceHash and then also have some Bitcoin (BTC) transferred to your platform wallet that you would be using to pay for the mining packages you want to purchase. That may require a certain level of verification if you are registering a new account. Also have in mind that in order to receive your reward you would need to be Tier 2 verified (not required to try your luck) and that requires identity and address verification! There are 3 different mining packages available – Bronze, Silver and Gold with 3 levels of each (S, M and L) available so 9 different packages in total. Bronze is for Zcoin (ZEC), Silver is for DOGE although the L level is for Bitcoin Cash (BCH) and Gold is for Bitcoin mining.

Each of the mining packages available is priced differently with the lowest one starting at sub $2 USD at the moment and the highest priced one is a little shy of $200 USD. The higher the price goes, the more hashing power and time you get to try and validate a block, thus your chances are getting higher. The more you pay however the less you will get if you manage to validate a block, but the chance of doing so is higher (the probability is listed for each package and it varies). With 1:3 or 1:4 probability the chances are high, but you can still buy a mining package and get nothing in return, so maybe not as much like a lottery, but more like gambling.

When you buy a mining packages shortly it starts mining and showing you how much time is left and how are you doing trying to validate a block for the specified crypto coin the mining package you bought for. There is no need to have the page open or anything, it will run for the specified time and you can find the results and your luck afterwards. Of course, there are some pretty graphics that are showing should you decide to spend time watching how things are progressing.

We’ve decided to start with the S or Small mining package for the three options available and then get three of each, so 9 in total for a total of 0.0009 BTC or about $17.37 USD with the current price of Bitcoin. Each of the packages ran for about 1 hour and although we got high percentages of being close to hit the reward, we did not have enough luck and did not manage to pull off validating any blocks with our 9 “lottery tickets”.

If you click on the smaller icon in the ACTIVE order section of any of the purchased mining packages you will get a more detailed graph and stats with information about it, so if you are curious and want to spend more time watching as things progress you can do so. Or you can just leave it to finish and then return to see the results of your luck or chance and if you managed to score any rewards or not and decide to maybe try again or not. Here is also another useful option you can take advantage of – the ability to stop an active mining package from the three small dots on the upper right corner.

The mining duration you get for the S-sized package is about 1 hour, for the M-sized one it is about 2 hours and for the L-sized one it is about 4 hours. There is no exact mention of the amount of hashpower you get with each of the packages, but on the detailed page you see how the spending of the amount paid in BTC is progressing. However when you purchase a mining package you are not charged the full amount, instead it gets depleted over the duration of the mining time you get. So, say you hit a block very early on and you can stop the mining package and not use up the remaining amount. You’ve already beaten the high odds, or would you continue and try hitting another block maybe.

There is a dedicated page showing all of your completed orders as an easy to view list including how close were you to hitting a reward and if any of the mining packages you bought actually managed to hit a block and score you are reward. If you click on any of the packages listed on the COMPLETED orders page you will also get a more detailed full stats for the whole mining time of the package, similar to the detailed data you can watch during the actual mining.

The closest we got a reward with our 9 S-sized mining packages was 89% on a Bronze S package for mining ZCash (ZEC) and that one had 1:118 chance according to the data when purchasing the package, so pretty good, although a little disappointed that we were not lucky enough to hit a block and get a reward. Maybe will give it a couple more tries and you are welcome to try your own luck with a few mining packages and see if you can manage to score a block reward or not.

Update: Meanwhile we have also given it another try with one package of the second M-sized levels for each and unfortunately our luck has not improved much and again we did not get to validate a block on either of the three crypto currencies with the higher mining packages. We are not ready to give up yet, so next come the L-sized ones, hopefully with better results or we are getting completely disappointed from our luck today, but maybe you would have better luck than us.

There is a new fork of GRIN based on the MimbleWimble protocol called Epic Cash (EPIC) that has officially launched their blockchain a day or so ago. EPIC can be CPU, GPU, and ASIC-mined with 3 different algorithms available for each type of hardware and block rewards are distributed according to a schedule that balances wide distribution with long-term security. One of the main goals of the project is to offer high level of privacy to the users with a monetary policy very similar to that of Bitcoin (BTC). This includes a maximum supply of 21 million coins and a higher initial emission in order to reach and synchronize with Bitcoin in terms of available coins in a couple of years time frame. The so called Epic Singularity will happe in 2028 when the Epic circulating supply intersects the number of Bitcoin’s circulating supply, at which point Epic Cash adopts the Bitcoin block reward and halving pattern. Until then the starting block reward is 16 coins halving around every year initially and then around every two until it reaches a halving every 4 years.

The Epic Cash blockchain is initially available to CPU, GPU, and ASIC miners by using three respective hashing algorithms: RandomX, ProgPow, and CuckAToo31+ wih different percent distribution for each one starting with higher CPU advantage and slowly transitioning to GPUs and then ASICs. Since for the moment there are not publicly available CuckAToo31+ ASIC miners the algo is available for GPUs as well, however work is being done by multiple manufacturers and maybe by the end of this year or early next year such devices might become available on the market (optimistically speaking). So far, so good the project looks interesting and promising, though not everything seems to be that great for non-advanced users interested in mining EPIC. If you are looking for a crypto exchange where you can trade EPIC, then you can head on to Citex.

First of all EPIC can currently be only solo mined and since it is based on GRIN codebase, just like GRIN it is not that user friendly running and mining it. LINUX users have a better advantage as for example the CUDA GPU miner is not officially available for Windows yet and the OpenCL one is giving trouble and using third party ProgPow miners for solo mining the coin is also a kind of a challenge with no pool available yet. CPU mining is working pretty well with the available miner, but solo mining with the already high difficulty could be a challenge for most users to mine even one block. mining pools should be coming out shortly with talk about icemining probably being the first on the train, though nothing official about that yet.

AS requested here comes a simple guide on how to solo mine Ethereum Ether coins on a local system or within a network with multiple mining rigs. Note that at this point it is already pointless to try local solo mining with CPU only, and if you do not have enough GPU power available and you end up with some bad luck you may not be able to solve a block in a long time. Also our experience shows that geth may lockup at times when solo mining not sending new work from the current block, so do monitor your mining rigs carefully should you decide to try it. If you want to mine in a pool, then you might want to check out our other Quick Guide on How to Mine Ethereum on Windows. Before you get started you need to download the geth and ethminer Windows binaries from the link below, then just follow the instructions below:

Generating wallet address:
– Open the geth folder and run geth-console.bat to start Ethereum in console mode
– The software will need to download the blockchain data, it can take some time
– In the console type: personal.newAccount("password")
– Instead of password in the quotes above write your own password and remember it well
– In the console type: eth.accounts
– This will list your Ethereum wallet address
– To check your account balance you can type: web3.fromWei(eth.getBalance(eth.coinbase), "ether")

Sending Ether to another wallet:
– First you need to unlock your account by typing in the console the following (replace password with your password): personal.unlockAccount(eth.accounts[0], "password")
– In the console type: eth.sendTransaction({from: 'your_address', to: 'recipient_address', value: web3.toWei(1, "ether")})
– In the above code replace your_address and recipient_address with the respective addresses, the example is for sending 1 Ether, but you can change the value depending on your needs

Starting geth for solo mining:
– To listen for connections only on the local system type: geth --rpc --rpcaddr "localhost" --rpcport 8545
– To be accessible on the local network type: geth --rpc --rpcaddr "192.168.0.123" --rpcport 8545
– Make sure that for local LAN accessibility you replace the rpcaddr IP address to the one that of the machine geth is running on, the 192.168.0.123 is just an example
– To be accessible on the Internet type: geth --rpc --rpcaddr "x.x.x.x" --rpcport 8545
– Make sure that for Internet accessibility you replace the rpcaddr IP address to the one that of the machine geth is running on, the x.x.x.x in the example will not work, also make sure that the 8545 port (or another one you decide to use) is forwarded

Starting ethminer for solo mining:
– For local system mining with ethminer on the same PC that geth is running on use: ethminer -G
– For mining on a system in the Local LAN where geth is installed and running use: ethminer -G -F http://192.168.0.123:8545
– Make sure that for local LAN mining the IP address of the system geth is running on is set correctly on the miner, the 192.168.0.123 is just an example, also make sure that there is no Firewall blocking connections
– For using mining rig to mine over the Internet on a PC with geth running in your local LAN use: ethminer -G -F http://x.x.x.x:8545
– For Internet access make sure that instead of the x.x.x.x in the example you set your external IP address and that the 8545 port is properly forwarded between the external IP and the system running geth

It seems that ethpool has just stopped accepting new users due to high load on their server, they have posted the following message: “Due too the high hashrate the pool currently does not accept new miners!”. So if you still haven’t started mining there, existing users can continue using the service, so now may just be the right time to try out solo mining.

Download geth and ethminer compiled for Windows and ready to be used…
