Solana Validators Explained

How validators fit into Solana’s high-performance blockchain design and consensus process.

What validators do

Validators participate in maintaining the network by processing activity, voting, and helping the chain reach agreement over state.

Validators and time ordering

Proof of History helps organize event order, but validators still perform the network work needed for consensus and ledger maintenance.

Why validator performance matters

A high-performance architecture depends on validators being able to process and communicate efficiently.

Validators and finality

Validators participate in the process that moves transactions toward finality, where state updates are treated as settled.

How to read validator sections

Read validators together with Proof of History, consensus, finality, and throughput. These ideas are connected in Solana’s design.
