How to run a Polkadot node?

When you are building products and dapp’s on a Substrate-based chain like Polkadot, Kusama or a custom Substrate, you will want to run your own node.

There are 3 types of nodes you can run.

An archive node keeps all the past blocks. An archive node makes it convenient to query the past state of the chain at any point in time.

A full node is pruned, meaning it discards all information older than 256 blocks, but keeps the extrinsics for all past blocks, and the genesis block. A node that is pruned this way requires much less space than an archive node.

Another type of node is a light node.

A light node has only the runtime and the current state, but does not store past extrinsics and so cannot restore the full chain from genesis.

Light nodes are useful for resource restricted devices.

You can find the instructions on how to setup a Polkadot node on the Polkadot Wiki node setup page. (https://wiki.polkadot.network/docs/en/maintain-sync)
