## What it is
Polkadot SDK is the consolidated Rust monorepo merging Substrate, Polkadot, and Cumulus, providing a framework for building blockchains and the Polkadot relay chain node client. It lets developers create custom, interoperable blockchains with pluggable consensus, runtime logic, and networking.

## Use cases
- build a custom blockchain with substrate
- run a polkadot relay chain node
- launch a parachain connected to polkadot
- develop a proof-of-stake blockchain in rust
- create a private permissioned blockchain
- implement custom runtime pallets for a chain

## When to choose
- you want to build a standalone or parachain blockchain with modular runtime components
- you need a production-tested node client for the polkadot ecosystem
- you want pluggable consensus, governance, and staking out of the box

## When to avoid
- you need a simple smart-contract-only dapp without running your own chain
- you are not working in rust or the polkadot ecosystem
- you want a lightweight toy blockchain for learning rather than a full framework
