# Node Types

## Node Types and Roles

**SOLVM's network architecture is built on four distinct node types, each playing a crucial role in maintaining the system's efficiency, security, and accessibility**

**1 , Validator Nodes**

* Role: Transaction processing, block generation, maintaining network consensus
* Requirements: SOVM staking, high performance hardware
* Selection mechanism: Probabilistic selection + ranking based on performance metrics

**2 , Relay Nodes**

* Role: Transaction propagation, enhancing network connectivity
* Requirements: Moderate performance hardware
* Incentives: SOVM rewards based on bandwidth provision

**3 , Archival Nodes**

* Role: Storage of complete historical data, support for audits and analysis
* Storage requirements: Large capacity storage, able to accommodate annual growth
* Data structure: Custom compression algorithm + differential storage

**4 , Light Clients**

* Function: Sending transactions, balance checks, simplified state verification
* Implementation: Mobile wallets, browser extensions
* Security: Verification through Merkle proofs, support for fraud proofs
