The devfee is based on the exact number of hashes produced. ViaBTC is picked because their initial connection difficulty is lower than most, which improves your chances of getting paid. Note that where you are in the world gets you a different server, so this may not be the case for you. UselethMiner can run in proxy mode to aggregate multiple downstream connections into fewer upstream connections. Each upstream connection can handle at most downstream connections see the --aggr option , more upstream connections are created as needed.
Particularly when you're running UselethMiner on multiple machines, you should be running the proxy somewhere to increase your revenue. The proxy will keep its upstream connection alive as long as possible, so if one of the miners restarts or loses connection you don't have to overcome the difficulty problem mentioned in the UselethMiner section again.
Due to its aggregating nature it also strongly reduces that problem if you connect multiple miners. Connecting four clients at 0. A UselethMiner-to-UselethProxy connection is automatically weakly encrypted after initial handshake, as some providers and networks get upset about stratum connections I'm looking at you Google Cloud, and your mandatory monthly support case and timezone-ignoring midnight phone-call!
You can force UselethMiner to encrypt the handshake as well if you know you're connecting to a UselethProxy by using a negative port number. You probably also want to use a common port like in that case. UselethProxy is based on the same code we've used to run Bitcoin pools, which is known to be able to handle thousands of connections per core.
That code has been adjusted for this project though, and I did not have thousands of CPUs available to test with, so I really can't say how much it can handle. For the sake of performance, simplicity, and reduced resource usage, the proxy is currently not a verifying proxy.
As such it is important you only connect well-behaving miners, as a rejected share can potentially bring down an entire upstream connection. For this reason the proxy maintains separate connection pools for UselethMiner clients which are know to be well-behaved and non-UselethMiner clients I've tested only ethminer.
Downstream connections' submits will be logged, but they will only be forwarded to the upstream connection if they match the required difficulty. UselethProxy reduces the difficulty for downstream CPU connections for better connection tracking, so a large share of submits will not actually be valid, and will not be forwarded.
This can be confusing if you look at the proxy's output. The devfee is based on difficulty shares. The proxy will divert client connections to the devfee pool as needed. This is usually just one of the client connections, though it may become more if you have hundreds of clients connected. Stats shown in on-screen output are delayed and calculated back from submitted share difficulties.
They are an approximation that is statistically correct if averaged long-term with a fixed number of clients with stable hashrate. In other words, they're not exact numbers, newly connected client may take a while to be calculated in, newly disconnected clients may still be counted, etc. This is due to the nature of stratum and is the same reason your pool hashrates are not exact. As with mining, the proxy has mostly been tested against the ViaBTC pool.
It will only work properly if the upstream connection you use sends an extranonce of at most two bytes 4 hex characters. You cannot connect the proxy to another proxy! Well - you can, but it will not work right. Please also read the OS-specific notes section before using. You generally want to supply one or more stratum connections and a threading strategy:.
The proxy is single-threaded. As it's non-verifying and pretty darn fast, odds are this is more than enough for you. If you need to go beyond a single thread, run multiple instances depending on the OS these can be bound to the same host and port , use a load-balancer, etc. You can connect to it with your own code, or run uselethminer If you suffix an RPC command to that line quotes , it will execute that command and exit the console, for scripting purposes.
UselethMiner attempts to use huge pages if available see OS-specific notes. On many machines this doubles performance or more , so you should care about getting it to work. UselethMiner tells you if huge pages are being used every DAG load: it logs either hugepages:yes or hugepages:no. The DAG will start conflicting and go into a reload loop. While the miner does its best to detect compatible CPUs for each backend flavor, this is not perfect. It may crash with an illegal instruction, in which case you should use the --flavor option to manually specify a backend to use.
On first run, the benchmark will generate a DAG which will be immediately discarded when actual mining starts. Hugepages are supported, both if reserved and mounted hugeadm , kernel command line and with transparent hugepages THP , the latter both in always and madvise mode. Mining has been tested reasonably well, and Linux is my primary development and test target for the proxy.
I run an Ubuntu 18 Bionic based box, your mileage may vary on other distros. The proxy attemps to adjust ulimits as needed. A --hide-console option is available to get rid of the console window if you want to run it in the background, start it from a script, etc.
Hugepages are supported, but they have to be enabled for your user. UselethMiner attempts to enable it, but UAC may not let it. Contrary to Microsoft's documentation on the matter, you will need to reboot your computer for the setting to take effect. Note that if you only check the policy after running UselethMiner, even if your user appears to be set, you don't know if it was there before or added by UselethMiner, and you should reboot to be sure.
I've had some issues getting it to work for Administrator and groups, but it seems to work for individual users. There are ways to configure this on Windows 10 Home as well according to Google. Windows 10 is my primary test and development target for the mining part of UselethMiner, but the proxy part has only seen basic testing. If you want to run the proxy on Windows - especially with more than a handful of clients - you probably want to disable the firewall on the incoming network interface, exclude the binary from Windows Defender, and all the other things you might need to do to have a server run properly on Windows.
It can be used simultaneously with a CPU backend, mining to the same stratum connection. To enable GPU mining with Metal, add --flavor-gpu metal parameters. To disable CPU mining, add --flavor none parameters. This was tested on an AS M1 Max. I fully expect it to work on an M1 Pro.
No idea about the original M1. There is currently no performance scaling option for the GPU backend. Therefore, it is not recommended to take cards with 5 gigabytes of video memory - they will turn off soon. The second criterion is performance or hash rate. It shows how many cryptographic operations the card makes per second.
This parameter can be found in the table of the best GPUs for mining. It can be bypassed, but it will require additional configuration steps. Moreover, they consume quite a lot of energy. Pay special attention to the PSU. You should not save on it, even if only one video card is involved in the Ethereum mining.
Any modern CPU will do. The processor power does not matter for Ethereum mining. Any with support for multiple GPUs. If there are not enough PCI-e ports, the cards can be connected through risers. Mining is done using a special application - a miner.
There are several of them and each has its own features. For example, some miners only work on Nvidia cards and some only on AMD cards. In addition, they often give different profits. All the most popular miners are already built into Kryptex. In addition, the hardware bencmark system selects the optimal miner for each of GPUs.
To find the most profitable miner, you need to download, configure and run them all. It can be quite difficult to do it manually. Kryptex does it all automatically. Choosing a mining pool is not an easy task. You can focus on the capacity, the size of the commission and the minimum payments. Let's move on to the most important thing - mining. To do this, you need to configure and run the miner. The first step is to create a configuration file for the miner you will mine on.
A config file is a. All miners work in the command line interface, so it's more convenient to run them this way. Full descriptions of all commands can be found in the Phoenixminer documentation. Once you have started mining, you can overclock your video card.
If done correctly, it is safe. This increases the hash rate and your profit. Usually an Afterburner app is used for overclocking. It allows you to adjust the frequencies of the core, memory, set the power consumption limit and fan speed. Ethereum depends mainly on the video memory frequency and usually does not use the video card core at full thrust.
Therefore, it is possible to increase the hash rate and at the same time reduce electricity consumption, heating and fan noise. Take three steps:. This is a basic overclock that will suit almost any miner. Advanced users can go further and do undervolting to further reduce consumption. When you have mined enough Ethereum, the question arises: how can you turn it into real money?
You can't pay with Ethereum in a store.
