Prysm node

Requirements

  • Get to know Prysm a bit
  • Server with 4 (v)cpus & 8 gb memory & 250 gb storage

Services

  • geth
  • beacon
  • validator
  • slasher
  • prometheus
  • grafana

All services are enabled by default.

Minimal Setup (beacon & validator only)

In case you want to run only beacon & validator (geth, slasher, prometheus, grafana get disabled) move the ./compose-examples/prysm-only/override-examples/docker-compose.beacon-validator.override.yaml file in the same folder as your docker-compose.yaml and rename it to docker-compose.override.yaml. Read up on docker-compose files & override to customize your setup further.

(optional) Configure your node

Public ip & other Prysm parameters/arguments

Configuration files are located in the folder ./config. To gain a better connectivity for your beacon node you should specifiy your public ip and/or your dns name in ./config/prysm/slasher/beacon.yaml. Follow the guide Improve Peer-to-Peer Connectivity.

Validator accounts with launchpad

Please complete the steps on launchpad and store the generated files of ~/eth2.0-deposit-cli/validator_keys in ./launchpad. The necessary directories need to be created. Please create the directories ./data/prysm/validator/wallets and put your wallet password in ./data/prysm/validator/passwords/wallet-password.

  1. Generate your validator(s) using launchpad and complete the process
  2. Copy your generated validator(s) from ~/eth2.0-deposit-cli/validator_keys to ./launchpad
  3. Run docker-compose -f create-account.yaml run validator-import-launchpad and use the same password as in the generation of the validator(s)

Repeat these steps as often as you like, restart your validator to make it notice your new accounts!

Validator accounts voluntary exit

  1. Copy exit-account.yaml to the project's root directory (this directory)
  2. Run ./prysm_validator_exit.sh public-key-of-your-validator

For instance: ./prysm_validator_exit.sh 0xabcde12345...

The "Expect" needs to be installed to execute prysm_validator_exit.sh. Run apt-get install expect to install expect

Validator accounts delete

  1. Copy delete-account.yaml to the project's root directory (this directory)
  2. Run ./prysm_validator_delete.sh public-key-of-your-validator
  3. Run docker-compose stop validator then docker-compose up -d validator to restart validator service

For instance: ./prysm_validator_delete.sh 0xabcde12345...

The "Expect" needs to be installed to execute prysm_validator_delete.sh. Run apt-get install expect to install expect

Validator accounts list

  1. Copy list-account.yaml to the project's root directory (this directory)
  2. Run docker-compose -f list-account.yaml run validator-list-accounts

Run your Prysm Ethereum 2.0 staking node

Start it up

Run with (as deamon with "-d")

docker-compose up -d

or run only certain services (in this case only beacon and validator)

docker-compose up -d beacon validator

Stop it

Stop services (or everything) like this

docker-compose stop validator slasher

Shut it down for good

Shut down your services (or everything) like this:

docker-compose down

Please note: This will also erase your logs, they are stored with your containers and will be deleted as well.

Monitoring

Logging

Docker takes care of log files and log file rotation as well as limit (set to 10x100mb log files for each service). View logs of a certain service (in this case beacon, only the last 100 lines)

docker-compose logs --tail=100 beacon

Prometheus

Runs on http://localhost:9090, scrapes data of beacon, validator and slasher.

Grafana

Grafana listens on http://localhost:3000 and uses the data provided by prometheus service.

Login with username admin and password admin (Grafana defaults), data source to Prometheus is already established and dashboards installed.

Prysm Web Interface

Runs on http://localhost:7500, a wallet is already created then signup with your web interface password.

If not, use Imported Wallet option to import the your keystores & set your web interface password.

FAQ

I keep missing attestations or keep getting warnings/errors about roughtime

E. g. error messages like this:

WARN roughtime: Roughtime reports your clock is off by more than 2 seconds offset=4h0m0.345549475s

Make sure the OS' clock is synced. For Windows 10 and its subsystem linux might run on different times, to check this run wsl and then date (may differ by the OS you have installed).

Ask google on how to get your OS' time synced again.

I want to use a specific Ethereum 1 node!

Edit the line with http-web3provider in ./config/prysm/slasher/beacon.yaml and set your Ethereum 1 node URL, e. g. use it with Infura.io and make it look like this: http-web3provider: "https://goerli.infura.io:443/v3/put-your-infura-id-here" (make sure to use "" for the url).
