Execution clients

Execution clients are upgraded versions of existing Ethereum clients like Besu, EthereumJS, Erigon, Geth and Nethermind. These clients have had the proof-of-work components removed and now rely upon a Consensus Client to perform the functions of a consensus mechanism.

Execution client Default Port

• geth 30303 TCP/UDP (Go)
• Besu 30303 TCP/UDP (Java, https://besu.hyperledger.org/en/stable/)
• Nethermind 30303 TCP/UDP
• Erigon 30303 TCP/UDP

• reth (Rust)

Activities

• Read about why beacon node controls the execution node and you must have one execution node per beacon node in lighthouse: https://github.com/sigp/lighthouse/blob/stable/book/src/merge-migration.md#connecting-to-an-execution-engine
• Ethereum execution layer synchronization nodes
