Download Prysm

the latest version of Prysm beacon node (beacon-chain) and run the checksum verification process to ensure that the downloaded file has not been tampered with.

cd
curl -LO https://github.com/prysmaticlabs/prysm/releases/download/v5.1.2/beacon-chain-v5.1.2-linux-amd64
curl -LO https://github.com/prysmaticlabs/prysm/releases/download/v5.1.2/beacon-chain-v5.1.2-linux-amd64.sha256

Run the checksum verification process.

sha256sum --check beacon-chain-v5.1.2-linux-amd64.sha256

Each downloadable file comes with it's own checksum. Replace the actual checksum and URL of the download link in the code block above.

Make sure to choose the amd64 version. Right click on the linked text and select "copy link address" to get the URL of the download link to curl.

Expected output: Verify output of the checksum verification.

beacon-chain-v5.1.2-linux-amd64: OK

If checksum is verified, extract the files and move them into the (/usr/local/bin) directory for neatness and best practice. Then, clean up the duplicated copies.

mv beacon-chain-v5.1.2-linux-amd64 prysmbeacon #rename the binary file for easy reference
chmod +x prysmbeacon
sudo cp prysmbeacon /usr/local/bin
rm -r prysmbeacon beacon-chain-v5.1.2-linux-amd64.sha256

Configure the Prysm Consensus Client

We will be running the consensus client and validator client of Prysm as separate services so that there is more flexibility to configure a failover node for maximum uptime when you decide it is needed.

Create an account (prysmbeacon) without server access for the Prysm Consensus Client & Validator Client to run as a background service. This type of user account will not have root access so it restricts potential attackers to only the Prysm Consensus Client & Validator Client services in the unlikely event that they manage to infiltrate via a compromised client update.

sudo useradd --no-create-home --shell /bin/false prysmbeacon

Create a directory for Prysm Beacon to store the blockchain and validator data of the Consensus layer. Move the validator_keys directory into this folder. Then set the owner of this directory to the prysmbeacon so that this user can read and write to the directory.

sudo mkdir -p /var/lib/prysm_beacon
sudo chown -R prysmbeacon:prysmbeacon /var/lib/prysm_beacon
sudo chmod 700 /var/lib/prysm_beacon

If there are no errors, create a systemd configuration file for the Prysm Consensus Client to run in the background.

sudo nano /etc/systemd/system/prysmbeacon.service

Paste the configuration parameters below into the file:

[Unit]
Description=Prysm Beacon Node (Holesky)
Wants=network-online.target
After=network-online.target

[Service]
User=prysmbeacon
Group=prysmbeacon

Once you're done, save with Ctrl+O and Enter, then exit with Ctrl+X. Understand and review your configuration summary below, and amend if needed.

Prysm Consensus Client configuration summary:

  1. --accept-terms-of-use: Accept the terms and conditions.

  2. --holesky: Run the Consensus Client service on the ETH Holesky testnet

  3. --datadir: Specify the directory for Prysm to store data related to the consensus client

  4. --execution-endpoint: URL to connect to the execution layer client

  5. --jwt-secret: File path to locate the JWT secret we generated earlier

  6. --monitoring-port: Port to connect to the metrics server. Used by Prometheus & Grafana for monitoring.

  7. --p2p-tcp-port/--p2p-udp-port: Sets the port for peer-to-peer communication. Defaults to 13000 & 12000 respectively.

  8. --rpc-port: RPC port exposed by the Prysm beacon node (default: 4000) that will be used by the validator and DVT clients.

  9. --rpc-host: Host on which the RPC server should listen (default: "127.0.0.1") that will be used by the validator and DVT clients.

  10. --grpc-gateway-port: Sets the port to connect to the consensus client

  11. --grpc-gateway-host: Sets the IP address to connect to the REST API of the consensus client that will be used by the validator and DVT clients. Use the internal IP address of your device here (check by running ip a) - e.g. 192.168.x.x. Defaults to 127.0.0.1 otherwise

  12. --http-mev-relay: URL to connect to external builders (e.g. MEV relays)

  13. --local-block-value-boost: What is the multiplier (in %) of the value of externally-built blocks in order to outsource block building vs building blocks locally. Set to 100 to be indifferent. Default =90

Start the Prysm Consensus Client

Reload systemd to register the changes made, start the Prysm Consensus Client service, and check its status to make sure its running.

sudo systemctl daemon-reload
sudo systemctl start prysmbeacon.service
sudo systemctl status prysmbeacon.service

Expected output: The output should say Prysm Consensus Client is “active (running)”. Press CTRL-C to exit and Prysm Consensus Client will continue to run. It should take just a few minutes for Prysm to sync on Holesky.

Use the following command to check the logs of Prysm Consensus Client’s syncing process. Watch out for any warnings or errors.

sudo journalctl -fu prysmbeacon -o cat | ccze -A

Expected output:

Press Ctrl+C to exit monitoring.

If the Prysm Consensus Client service is running smoothly, we can now enable it to fire up automatically when rebooting the system.

sudo systemctl enable prysmbeacon.service

Verify the Initial State roots (Checkpoint Sync)

  1. Verify the Block Root and State Root with your journalctl output

  2. journalctl output
