🖥️Node

Overview

In a Proof-of-Stake (PoS) Ethereum Virtual Machine (EVM) compatible blockchain, nodes form the foundational infrastructure that ensures the network’s functionality, security, and decentralization. Nodes are broadly classified into two categories—Validator Nodes and Non-Validator Nodes—each fulfilling specific roles within the ecosystem. This section provides a high-level introduction to these node types and their contributions to a PoS EVM network, setting the stage for detailed exploration in subsequent sections.

Node Types and Roles

Validator Node

Validator Nodes are active participants in the PoS consensus mechanism. By staking a required amount of cryptocurrency, these nodes are responsible for validating transactions, proposing new blocks, and finalizing them through a process known as "sealing." They play a critical role in maintaining the network’s security and integrity, earning staking rewards and transaction fees in return for their efforts.

Non-Validator Node

Non-Validator Nodes, identified by a seal: false configuration, do not engage in the consensus process or block production. Operating as full nodes or light nodes, they focus on synchronizing with the blockchain, verifying transactions and blocks for local use, and relaying data across the network. These nodes enhance accessibility, support decentralized data propagation, and provide infrastructure for applications and users without the resource-intensive demands of validation.

Network Contribution

Validator Nodes drive the core operations of block creation and consensus, ensuring the blockchain progresses securely and consistently. Non-Validator Nodes complement this by bolstering network resilience, enabling data availability, and facilitating broader participation. Together, they create a balanced and robust PoS EVM environment.
