![]() Bitcoin is a digital asset, with a high exchange value – meaning people buy, sell, and trade with it. In a sense, miners play the role of a digital accountant. Mining is the process of solving cryptographic puzzles to add transactions to a blockchain. However, not many people know how to ‘mine’ Bitcoin. It accepts the user/pass combination just fine, prints "Shutdown: In progress." in the terminal window and quits after a few seconds.The cryptosphere is growing every day, and most people have heard of Bitcoin by now. bitcoin-cli -rpcuser=(user) -rpcpassword=(password) -stop (Starting it via sudo is the only way for me to see the live log in terminal.) bitcoind -server -rpcuser=(user) -rpcpassword=(password) Thanks in advance for every kind help I can get! What am I doing wrong? The username and password I use for cgminer are 100% the same as in the nf. Starting it wouthout sudo gives me a permission error on my mining devices. ![]() cgminer -o :(port) -u (username) -p (password) -btc-address (address) Wrong password - but it's the correct one. Which starts just fine and then prints "wrong password attempt" or something like that in the log terminal window when I start cgminer with the correct rpc user/pass. I tried many different ports and many different username/password variations in the. Many older threads told me to only use Bitcoin Core 0.19.1 Because I did find various different startup commands via Google for cgminer and am completely puzzled which of them I should use and which I should not use. I hope other people google'ing the current versions of cgminer 4.9.2 and Bitcoin Core 0.21.0 + Bitcoin solo mining will find this thread with some helpful answers/a good tutorial made by someone nice in this thread. So I try it out first with low end miners.ġ: Are there any other commands I should add besides -o -u username -p passsword -btc-address address?Īre there any specific entries I should make for the nf file besides setting up a username and password and setting up the port with an entry in said file?Ģ: I have also read that a successfully setup cgminer with Bitcoin Core will display the textline "mining to (address)" in the cgminer window every few seconds, is that correct? What am I doing wrong if I do not see this message?ģ: What startup commands do I need for Bitcoin Core for this solo setup besides -server (or is it -server with 2x "-"?) Don't want to find out that Bitcoin Core does not support solo mining anymore with cgminer and end up with useless brand new mining hardware. I plan on testing everything out with the solo setup first before I buy any larger amounts of miners to get into it more seriously. Solo mining is selfish and the probability of finding a block with outdated mining hardware is low. The miners itself work just fine, I have tested them with a Bitcoin mining pool and they are hashing away nicely. Is that correct?Īm wondering if the current cgminer 4.9.2 version and Bitcoin Core 0.21.0 version work well together with solo mining Bitcoin? I am using a Raspberry Pi 4 with the latest Raspbian OS version and have the miners plugged into the USB ports. I also found out that I need to use the startup command -btc-address (address) in order to actually receive mined Bitcoin to my wallet. But I think it could have been an outdated thread and the latest cgminer and Bitcoin Core versions may have already fixed that issue so that one can solo mine again? Can't find the thread anymore where I have read this. I have researched a lot about solo mining with cgminer and Bitcoin Core and have found people saying that only Bitcoin Core 0.19 supports solo mining with cgminer because of some technical details.
