Setting up an Ethereum Node for TxStreet

These instructions are meant for DigitalOcean, but you can use the same steps with some modifications to create a node on other cloud providers.

System Requirements

  • At least 2TB of storage recommended On DigitalOcean, use a large storage optimized disk. Do not use an external volume as the read and write speeds are not fast enough.
  • 16GB memory
  • At least 4 CPU cores

Setup

  1. Create the droplet on Digital Ocean.
  • Use the same region and datacenter as your other droplets and databases.
  • Ubuntu 23.04.
  • Storage optimized dedicated cpu with 1.5x SSD and at least 1.76 TB NVMe SSD.
  • Add your SSH key if you wish.
  • Add the tag 'geth'.
  • Click create droplet.
  1. Start syncing the execution client client 'geth'.
  • SSH into the droplet as the root user.
  • add-apt-repository -y ppa:ethereum/ethereum
  • apt update
  • apt install geth
  • mkdir /root/ethereum
  • openssl rand -hex 32 | sudo tee /root/ethereum/jwt.hex > /dev/null
  • nano /etc/systemd/system/geth.service
  • Paste the following and save:
[Unit]
Description=Geth

[Service]
Type=simple
User=root
Restart=always
RestartSec=12
ExecStart=/usr/bin/geth --http --http.corsdomain *  --http.addr 0.0.0.0 --http.api admin,db,eth,miner,web3,net,personal,txpool --ws --ws.addr 0.0.0.0 --ws.api admin,db,eth,miner,web3,net,personal,txpool --ws.origins *  --txpool.globalslots 75000 --txpool.accountslots 64 --txpool.accountqueue 16 --txpool.globalqueue 5000 --txpool.lifetime 24h0m0s --maxpeers 200 --authrpc.jwtsecret /root/ethereum/jwt.hex
[Install]
WantedBy=default.target
  • systemctl daemon-reload
  • service geth start
  • Verify the service is running properly with service geth status
  • systemctl enable geth.service
  1. Start syncing the consensus client, 'prysm'.
  • mkdir /root/prysm
  • cd prysm
  • curl https://raw.githubusercontent.com/prysmaticlabs/prysm/master/prysm.sh --output prysm.sh && chmod +x prysm.sh
  • nano /etc/systemd/system/beacon-chain.service
  • Paste the following and save:
[Unit]
Description=Prysm Consensus Client BN (Mainnet)
Wants=network-online.target
After=network-online.target
[Service]
User=root
Group=root
Type=simple
Restart=always
RestartSec=5
ExecStart=/root/prysm/prysm.sh beacon-chain \
  --mainnet \
  --datadir=/root/prysm/data \
  --execution-endpoint=http://127.0.0.1:8551 \
  --jwt-secret=/root/ethereum/jwt.hex \
  --checkpoint-sync-url=https://sync-mainnet.beaconcha.in \
  --genesis-beacon-api-url=https://sync-mainnet.beaconcha.in \
  --accept-terms-of-use
[Install]
WantedBy=multi-user.target
  • systemctl daemon-reload
  • service beacon-chain start
  • Verify the service is running properly with service beacon-chain status
  • systemctl enable beacon-chain.service
  1. Install nodejs and tmp-bulk-geth-api. This service will always run with pm2 and allow for bulk ipc requests to the geth node.
  • cd /root
  • curl https://raw.githubusercontent.com/creationix/nvm/master/install.sh | bash
  • exit and log back in with SSH.
  • nvm install node
  • npm install -g pm2
  • git clone https://github.com/txstreet/tmp-bulk-geth-api.git
  • cd tmp-bulk-geth-api
  • npm install
  • pm2 start "node index"
  • pm2 save
  • pm2 startup
  1. Monitor geth and prysm to make sure they complete syncing.
  • Monitor geth sync status with geth attach and then eth.syncing. It will return false if it is fully synced.
  • Monitor prysm by checking the beacon-chain service logs.
  1. Apply updates whenever a new version of geth or prysm is released.
  • To update geth apt update && apt install geth, then service geth restart
  • To update prysm service beacon-chain restart
