Use the following checklist to check the status of your nodes and validators. If you run into issues, generate a troubleshooting report using our troubleshooting checklist.
If you end up generating a troubleshooting report, your report will include your selected configuration.
Many common issues are resolved by the steps in our Quickstart guide. We recommend reviewing the quickstart guide before continuing below.
Execution client:
Nethermind
Besu
Geth
Operating system:
Linux, MacOS, Arm64
Windows
You can check your Geth execution node's sync status by running geth attach (IPC) or geth attach http://localhost:8545 (HTTP) from a separate terminal. Then type eth.syncing. A sync status of false indicates that your node is fully synced.
You should periodically see more than a few peers reported through Geth's log output. Look for output in the format of peercount=12. Refer to Geth's Connecting To The Network documentation for more detailed peer health monitoring guidance.
Execution client:
Geth
Nethermind
Besu
Use geth version to check Geth's version. See Geth's releases page and join their Discord to stay up to date as we approach Mainnet Merge.
You can check your beacon node's sync status by running curl http://localhost:3500/eth/v1/node/syncing | jq from a separate terminal window. When you see "is_syncing":false, your beacon node is fully synchronized with the beacon chain. When you see "is_optimistic":false, your beacon node sees that your execution node is either 1) not yet started, 2) hasn't synced past the merge block or 3) fully synchronized with the execution-layer blockchain.
You should periodically see more than a few peers reported through your beacon node's log output. Look for output in the format of peers=12. You can issue curl http://localhost:8080/healthz from a separate terminal window to check connectivity status. If you see currentConnectionError: no contract code at given address, your execution node may still be syncing. Otherwise, if you don't see any errors, your beacon node is connected to peers.
Ensure that you're using the latest stable Prysm release. Check Prysm's version by issuing the following command: prysm.sh beacon-chain --version (Linux) prysm.bat beacon-chain --version (Windows).
Issue curl http://localhost:3500/eth/v1alpha1/node/eth1/connections from a separate terminal window. If you see currentConnectionError: no contract code at given address, your execution node may still be syncing. Otherwise, if you don't see any errors, your beacon node is connected to your execution node. This output can be interpreted as "EN-BN connection is healthy": {"currentAddress":"http://localhost:8551","currentConnectionError":"","addresses":["http://localhost:8551"],"connectionErrors":[]}
Prysm will output an error if you attempt to provide an invalid Ethereum wallet address as a fee recipient address. You'll see warnings if a fee recipient address hasn't been provided. See Configure Fee Recipient for more information.

Paste your validator's public key (available in your deposit_data-*.json file) into a blockchain explorer like beaconcha.in to check the status of your validator.
Running into unexpected output, warnings, or errors? Although this is unintuitive, many errors and warnings are expected and have been identified in the below list of troubleshooting scenarios and solutions. We gratefully ask that you review this before asking for support.
Issue still not resolved? Generate a troubleshooting report below. Head over to Discord and paste your report for additional troubleshooting assistance.

You can check your Geth execution node's sync status by running geth attach (IPC) or geth attach http://localhost:8545 (HTTP) from a separate terminal.Then type eth.syncing . A sync status of false indicates that your node is fully synced.
Running a cryptocurrency validator node can be an excellent strategy for earning passive income. By carefully selecting the right blockchain, understanding staking rewards and yields, and marketing your validator node effectively, you can potentially generate substantial income.
Verify that you're running Prysm v3. 0.0 by issuing the following command: prysm.sh beacon-chain --version (Linux) prysm. bat beacon-chain --version (Windows) and the same for the validator command.
Prysm is an Ethereum proof-of-stake client written in Go. You can use Prysm to participate in Ethereum's decentralized economy by running a node and, if you have 32 ETH to stake, a validator client. If you're new to Ethereum, you may enjoy our beginner-friendly Nodes and networks explainer.
Syncthing REST API. The most reliable way to check Syncthing status is by using Syncthing's REST API, which can be found here: http://localhost:8384/rest. ...
Syncthing-cli (Command Line Interface) You can also install and configure Syncthing-cli, a command line tool for the Syncthing API.
A pre-synced Geth node saves you the syncing time, which is normally more than 2 days. Using Launchnodes pre-synced nodes it will take you 1 or 2 hours.
What is the average ETH staking APY? The average ETH staking APY is roughly 4% for validators that do not utilize MEV-Boost. Validators with MEV-Boost enabled average roughly 5.69%.
Validators are responsible for producing blocks and the security of the network. Since Validators validate all shards, high requirements are set for running them (an 8-Core CPU with 16GB of RAM and 1 TB SSD of storage). The cost of running a block-producing validator node is estimated to be $330 per month for hosting.
As decentralized actors, nodes enhance network security and enable the execution of smart contracts. At the time of writing, over 10,000 nodes are active on the Ethereum network.
To check the sync status, use the eth_syncing JSON-RPC method. When it returns false , Nethermind is considered fully synced with all block bodies and receipts needed to work properly as a validator.
Adding new validators to your already-running Prysm instance is quite simple! Go through the launchpad process again, generate a new deposit keystore using the Ethereum validator deposit cli, then run the validator accounts import command again as you used when you added your first validator key.
Crypto traders make money every day from changes in the Ethereum value. It is also worth investing in the ETH to receive passive income from staking. Developers need it to create projects on the blockchain, and ordinary users need it to pay for gas and use Web3 applications on the Ethereum blockchain.
- Beacon Chain: The core chain in Ethereum 2.0 that coordinates and manages validators. It's responsible for proposing new blocks and maintaining the overall network consensus. - Validators: Participants responsible for validating transactions and adding them to the blockchain.
To enable snap sync, chain operators need to spin up a node which is exposed to the network and has transaction gossip disabled. For snap sync, all op-geth nodes should expose port 30303 TCP and 30303 UDP to easily find other op-geth nodes to sync from.
According to ethereum. org's page on nodes and clients, Erigon can perform a full archive node sync using around 2 TB of disk space in less than three days.
