It enables the operation of beacon nodes to track network state and the running of validator nodes to propose blocks and sign attestations. The project includes an MEV-boost integrated client that routes blocks through external relays and builders to optimize transaction fee rewards. It provides a slashing protection database to prevent conflicting signatures and supports remote key signing to keep private keys on external secure services. The software covers the full staking lifecycle, including validator activation, fund withdrawal, and exit validation. It manages data through checkpoint synchronization and archival hosting, while providing observability via performance metrics export and validator monitoring. Security is handled through authenticated execution node coupling and encrypted communication between nodes. ## Tags ### Data & Databases - [Proof-of-Stake Consensus](https://awesome-repositories.com/f/data-databases/proof-of-stake-delegation/proof-of-stake-consensus.md) — Implements a full Ethereum consensus layer providing a proof-of-stake client for block validation and network consensus. - [Checkpoint Sync Methods](https://awesome-repositories.com/f/data-databases/blockchain-sync-pipelines/checkpoint-sync-methods.md) — Accelerates initial node synchronization by downloading a recent finalized state from a trusted source. - [Ethereum Proof of Stake Validation](https://awesome-repositories.com/f/data-databases/ethereum-proof-of-stake-validation.md) — Runs a validator node to secure the Ethereum network by proposing blocks and signing attestations. - [Ethereum Staking Lifecycle](https://awesome-repositories.com/f/data-databases/ethereum-staking-lifecycle.md) — Manages the process of activating validators, withdrawing staked funds, and safely exiting the network. - [Validator Key Storage](https://awesome-repositories.com/f/data-databases/proof-of-stake-delegation/validator-lifecycle-management/validator-key-storage.md) — Handles the secure import and storage of keystore files used to sign blocks and manage stakes.
