Published 6 months ago • 1 min read

GM Surgers,

Surge's Web3 Course is tailored towards people of all levels.

Whether you're already working in crypto and want a free, technical overview or you're just getting into the weeds of Web3.

We're releasing chapters to subscribers for free on YouTube and this week, we’re looking into nodes.

What are nodes and how do they work?

Nodes - What allows blockchains to exist?

In Web3, a node is a device linked to a cryptocurrency network that may produce, receive, store and move data.

Open and permissionless blockchains like Bitcoin or Ethereum allow anyone to run a node.

However, running a node requires a high-speed internet connection and computational power. If you’re running a full node, the node needs to be online all the time. However, you can also run light clients.

But, why do blockchains need nodes?

Nodes are connected together in a decentralized network and they validate and store data while ensuring that the network remains sufficiently decentralized.
