## What it is
snarkOS is a decentralized operating system for zero-knowledge applications, forming the backbone of the Aleo network. It implements node software for validators, clients, and provers that verify transactions and store encrypted application state in a publicly-verifiable manner.

## Use cases
- run an Aleo validator node for consensus
- run an Aleo client node to query network state and relay transactions
- run a prover node to solve the Aleo puzzle
- spin up a local devnet for zero-knowledge application development
- verify and store encrypted state for ZK applications

## When to choose
- you want to participate in the Aleo network as a validator, client, or prover
- you are developing or testing zero-knowledge applications on Aleo and need a local devnet
- you need publicly-verifiable transaction verification with encrypted state

## When to avoid
- you need a general-purpose blockchain node unrelated to Aleo
- you want a simple ZK proof library rather than full node infrastructure
- you lack 64-bit hardware or the resources required to run network nodes

## Facets
