Prysm
Prysm is a Go implementation of the Ethereum consensus layer, providing an Ethereum proof of stake client, beacon node, and validator client. 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.
Features
- Proof-of-Stake Consensus - Implements a full Ethereum consensus layer providing a proof-of-stake client for block validation and network consensus.
- Ethereum Beacon Node Operation - Maintains a node that tracks the network state, syncs blockchain data, and provides API access for validators.
- Checkpoint Sync Methods - Accelerates initial node synchronization by downloading a recent finalized state from a trusted source.
- Ethereum Proof of Stake Validation - Runs a validator node to secure the Ethereum network by proposing blocks and signing attestations.
- Ethereum Staking Lifecycle - Manages the process of activating validators, withdrawing staked funds, and safely exiting the network.
- Validator Key Storage - Handles the secure import and storage of keystore files used to sign blocks and manage stakes.
- Slashing Prevention - Maintains a persistent local record of signed messages to prevent conflicting headers and avoid slashing penalties.
- Ethereum Beacon Nodes - Implements a network node that tracks validator activity and synchronization state for the Ethereum PoS chain.
- Execution Node Coupling - Establishes a secure authenticated channel to a separate execution client for verifying transaction data.
- Staking Withdrawals - Provides capabilities to transfer validator earnings or the entire stake from the chain to a chosen address.
- Validator Exit Processing - Manages the process for validators to voluntarily leave the network and stop participating in consensus.
- Ethereum Validator Clients - Provides a dedicated validator client for managing keys and signing blocks and attestations.
- Blockchain Archivers - Maintains a node that stores the complete historical state of the blockchain for rapid data retrieval.
- Historical Data Archiving - Supports storing extended blockchain data locally to speed up the retrieval of historical queries.
- MEV Reward Optimization - Integrates with specialized relays and builders to maximize transaction fee tips and block rewards.
- gRPC Node Communication - Uses a high-performance gRPC framework to exchange encrypted data between the beacon node and validator.
- MEV Block Routing - Integrates with specialized relays and builders to optimize block production and increase validator rewards.
- MEV-Relay Integration - Routes block proposals through external builders and relays to maximize transaction fee rewards.
- Remote Signing - Supports remote signing services to keep private keys off the local machine for increased security.
- Remote Validator Signing - Supports remote key signing to keep private keys on external secure services.
- MEV-Boost Integrated Clients - Includes an MEV-boost integrated client to optimize transaction fee rewards via external relays and builders.
- Observability Metrics Exporters - Exposes internal performance statistics via a standardized endpoint for external monitoring and alerting tools.
- Blockchain Network Monitors - Tracks validator performance and node metrics to prevent slashing and ensure high uptime.
- Validator Performance Tracking - Tracks block proposals, attestations, and slashing events for specific validators to ensure high uptime.
