## What it is
Lotus is the reference implementation of the Filecoin decentralized storage network, written in Go. It ships as a suite of command-line applications (lotus daemon, lotus miner, lotus worker) for running nodes, storing data, and operating as a storage provider.

## Use cases
- run a Filecoin full node and sync the chain
- store and retrieve files on the Filecoin network
- become a Filecoin storage provider and rent out disk space
- create a wallet and send or receive FIL
- interact with the Filecoin blockchain from the command line or JSON-RPC
- verify that storage providers are storing data correctly

## When to choose
- you need the canonical, full-featured Filecoin node implementation
- you want to run a storage provider operation on Filecoin mainnet
- you need a Go-based node with JSON-RPC access for building Filecoin tooling
- you want to participate in the Filecoin network on Linux or macOS

## When to avoid
- you need Windows support, which is not yet available
- you lack the heavy hardware requirements (32 GiB RAM, large SSD for chain data)
- you only want lightweight wallet or exchange interactions rather than running a node
- you want a simple centralized cloud storage solution

## Facets
- artifact type: application
