Prysm can be installed on macOS systems with Docker. This page includes instructions for performing this method.
NOTICE: The Prysm installation script is the easiest and most efficient way of installing the latest binaries. Instructions for using it can be found here.
Have questions? Stop by the #documentation channel on Discord and let us know.

Installing the beacon chain and validator
- Ensure you are running the most recent version of Docker by issuing the command:
- To pull the Prysm images, issue the following commands:
This process will also install any related dependencies.
For advanced users, the beacon-chain and validator images with Busybox debugging tools bundled in can be fetched instead by appending
-alpineto the end of the images in the
pullcommands above. For example:
docker pull .../prysm/validator:latest-alpine.
Connecting to the testnet: running a beacon node
Below are instructions for initialising a beacon node and connecting to the public testnet. To further understand the role that the beacon node plays in Prysm, see this section of the documentation.
NOTICE: It is recommended to open up port tcp/13000 and udp/12000 on your local router to improve connectivity and receive more peers from the network. To do so, navigate to
192.168.0.1in your browser and login if required. Follow along with the interface to modify your routers firewall settings. When this task is completed, append the parameter
--p2p-host-ip=$(curl -s ident.me)to your selected beacon startup command presented in this section to use the newly opened port.
To start your beacon node, issue the following command:
This will sync up the beacon node with the latest head block in the network.
Not getting enough peers? Refer to the improve P2P connectivity section of this documentation for tips on network configuration.
NOTICE: The beacon node must be completely synced before attempting to initialise a validator client, otherwise the validator will not be able to complete the deposit and funds will lost.
Staking ETH: Running a validator client
For step-by-step assistance with performing a deposit and setting up a validator client, see the activating a validator section of this documentation.
Once your beacon node is up, the chain will be waiting for you to deposit 32 Goerli ETH into a validator deposit contract in order to activate your validator (discussed in the section below).
If you need Goerli ETH, follow the instructions found on prylabs.network to use the testnet faucet. Otherwise, you can contact a team member on Discord to be sent some.
Please note that it may take up to 12 hours for the nodes in the network to process a deposit. Once the node is active, the validator will immediately begin performing its responsibilities.
In your validator client, you will be able to frequently see your validator balance as it goes up over time. Note that, should your node ever go offline for a long period, a validator will start gradually losing its deposit until it is removed from the network entirely.
Congratulations! If you've made it this far, you are now running Ethereum 2.0 Phase 0.
Managing the beacon node with Docker
Below are various methods of controlling the beacon node in Docker installations.
The beacon node can be halted by either using
Ctrl+c or with the command:
To restart the beacon node, issue the following command:
To delete a corrupted container, issue the following command:
To recreate a deleted container and refresh the chain database, issue the start command with an additional
