What is a WebSocket node?

A WebSocket node refers to a server within a blockchain or decentralized network, that uses WebSockets for communication. Unlike traditional HTTP requests, WebSockets in Node.js enable persistent, two-way communication between a client and the blockchain node.

What are WebSockets used for?

WebSocket is used to enable real-time communication between the client and a node. A typical Node.js WebSocket server can push data instantly to clients, making it especially useful for applications requiring live updates, such as financial dApps or gaming platforms.

What is the difference between JSON-RPC and WebSocket?

A node with WebSockets connection makes possible tasks like monitoring transactions and receiving event updates without needing to constantly re-establish a connection, as opposed to the more traditional request-response flow of JSON-RPC.

GraphQL vs WebSocket: How do they compare?

While WebSockets focus on communication efficiency, GraphQL emphasizes data retrieval efficiency. GraphQL provides a structured way to request specific data. On the other hand, node WebSocket clients have a continuous connection to a server, making it more suitable for applications requiring constant data flow.

How to use WebSockets in Node.js?

GetBlock provides WebSocket endpoints for different blockchain networks (e.g., Ethereum, BSC, Solana, etc.). You'll need to sign up for an API key from GetBlock and obtain the URL for the blockchain you want to connect to using WebSocket and Node.js. An example of the URL: wss://go.getblock.io/YOUR_ACCESS_TOKEN.

WebSockets Nodes

WebSocket (NEVM) in Syscoin is a communication protocol that enables real-time, bidirectional interaction with Syscoin's Network-Enhanced Virtual Machine (NEVM). It allows applications to receive instant updates on blockchain events, such as new transactions or changes in contract states, without constant polling. This enhances the responsiveness of decentralized applications on Syscoin platform.
