Infura is a node in the Ethereum network. It’s one of the most popular ways to connect to the Ethereum network, and it’s used by a number of popular Ethereum wallets and applications.
There are a few different types of nodes in the Ethereum network, but Infura is what’s known as an “archive node.” That means it keeps a complete record of all the transactions that have ever happened on the Ethereum network.
That might sound like a lot of data, but Infura actually only stores a tiny fraction of the total data that’s out there. The full history of the Ethereum network is stored on every single node in the network.
But Infura only stores the most recent history.
That’s why Infura is so popular. It’s a lot faster and easier to connect to an Infura node than it is to run your own node.
And because Infura is run by a company called IPFS, you can trust that their servers are reliable and secure.
So, is Infura an Ethereum node? Yes, it is. And it’s one of the best ways to connect to the Ethereum network.
