List of Web3 RPC Nodes and Settings

What is RPC in crypto?

Remote Procedure Call or RPC is a type of computer server (or a node, as it is referred to in crypto lingo) that makes communication with different servers a simple process.

In simpler terms, open-source dApps (Decentralized Apps) supported by blockchain do not have a central authority. Thus, RPC helps a dApp and its users to communicate, make transactions and access information on a blockchain.

How does RPC work?

RPC is a lightweight server based on a client-server model. The one requesting information is generally the client (a dApp in this case) and the one providing the requested information is a server (the blockchain the dApp is operating on).

For example, a gaming dApp based on the Ethereum blockchain can use Ethereum RPC node to communicate with it.

What is an RPC URL?

RPC URL is basically the endpoint of an RPC node. Like all URLs, it serves as a unique identity of a node.

For example, the RPC URL for Ethereum Pocket Portal will be different than that for Binance Smart Chain. Thus, each Blockchain RPC has a distinctive URL that differentiates it from others.

Essentially, when a client (a dApp) tries to request information or a server (a blockchain) tries to send information to a client, it is an RPC URL that is used to do the needful.
