    Founder of Loopring Foundation Daniel Wang shared in his blog clear instruction on how to forge Lightning Bitcoin Original link: How to Run Lighting BTC Node and Start Mining I invested 50 BTC into Lighting BTC (LBTC), so during the weekend I tried to mine LBTC for fun.medium.com I invested 50 BTC into Lighting BTC (LBTC), so during the weekend I tried to mine LBTC for fun. Install and Run 1. Start an EC2 Server Without prior knowledge, I chose a x1e.4xlarge instance and added 400G SSD storage. 2. Secure My Server I need to setup the firewall to secure my server. sudo ufw allow ssh sudo ufw allow 8333 sudo ufw default deny incoming sudo ufw default allow outgoing sudo ufw enable [edited]: Lighting network use 9333 instead of 8333. sudo ufw allow 9333 3. Install LightingBTC software Ligiting BTC node is being actively developed, and the documentation is really incomplete. I decided to go with bitcoin-unlimited and then replace the binaries with those downloaded on lbtc.io. sudo apt-get install software-properties-common sudo add-apt-repository ppa:bitcoin-unlimited/bu-ppa sudo apt-get update sudo apt-get install -y bitcoind Then I installed libraries required by LBTC, just in case they are not required by bitcoin-unlimited. sudo apt-get install -y libzmq5 libevent-dev libboost-chrono-dev libboost-filesystem-dev libboost-program-options-dev libboost-dev libboost-all-dev You can download bitcoind and bitcoin-cli from lbtc.io. I found there is no directly URL to download, so I downloaded them manually and put it into my own github repository. You should ALWAYS download the software from lbtc.io. wget https://github.com/dong77/lbtcnode/raw/master/bitcoind wget https://github.com/dong77/lbtcnode/raw/master/bitcoin-cli chmod +x bitcoind bitcoin-cli sudo mv bitcoind /usr/bin sudo mv bitcoin-cli /usr/bin 4. Config Swap Space Running a full bitcoin node uses a little over 1GB of memory, and I don’t know how much memory it needs to run a Lighting BTC node. The node I created has 16GB, but in case the one you run has less memory, I’ll make some spare “virtual memory” using swap space. sudo fallocate -l 1g /swap1.swap sudo chmod 0600 /swap1.swap sudo mkswap /swap1.swap sudo swapon /swap1.swap sudo vi /etc/fstab Add this line at the end of the file: /swap1.swap none swap sw 0 0 5. Add a User I’ll make a bitcoin user account and give it the ability to use “sudo” so you can do some system administration from the bitcoin user if you want to. sudo adduser --system --group --shell /bin/bash bitcoin sudo usermod -a -G sudo bitcoin 6. Set up log rotation for your bitcoin logs. This will ensure that your logs don’t grow too big and use up all your disk space. sudo vi /etc/logrotate.d/bitcoin-debug Enter into it: /home/bitcoin/.bitcoin/debug.log { rotate 5 copytruncate daily missingok notifempty compress delaycompress sharedscripts } 7. Configure Bitcoind sudo mkdir /home/bitcoin/.bitcoin sudo vi /home/bitcoin/.bitcoin/bitcoin.conf And paste the following as content: server=1 daemon=1 rpcuser=bitcoin rpcpassword=ANY_PASSWORD_WILL_DO Then copy the file so that I can use bitcoin-cli as the default “ubuntu” user. sudo mkdir .bitcoin sudo cp /home/bitcoin/.bitcoin/bitcoin.conf .bitcoin/ 8. Set Up a Systemd Service Set up the bitcoin daemon to auto-run: sudo vi /etc/systemd/system/multi-user.target.wants/bitcoind.service Enter into it: [Unit] Description=Bitcoin Server After=network.target After=syslog.target [Install] WantedBy=multi-user.target Alias=bitcoind.service [Service] User=bitcoin Group=bitcoin Type=forking # Start main service ExecStart=/usr/bin/bitcoind --daemon ExecStop=/usr/bin/bitcoin-cli stop Restart=always PrivateTmp=false Reboot the server: sudo reboot Now bitcoind should have been started automatically; or you can reload systemd and start bitcoind manually: sudo systemctl restart bitcoind sudo systemctl status bitcoind If you want to stop bitcoind, use this command: sudo systemctl stop bitcoind Start to Mine LBTC First I need an address: sudo bitcoin-cli getnewaddress sudo bitcoin-cli dumpprivkey 1L3ur9z8AydjnKdE8fXmpRTi3wtxcWJ2eJ I need to backup the private key printed by this command. sudo bitcoin-cli register 1L3ur9z8AydjnKdE8fXmpRTi3wtxcWJ2eJ loopring Apparently I need some LBTC to register as a miner, so I asked someone for 5 LRC. Then run the registration command again, it succeeded. Now I’m ready to mine. sudo bitcoin-cli startforging 1L3ur9z8AydjnKdE8fXmpRTi3wtxcWJ2eJ Future Work I need to ask other LBTC miners to vote for me, and I may have to vote back so we can form a partnership.
