WebSockets

WebSocket RPC (Remote Procedure Call) is a communication protocol that allows clients (such as wallets or dApps) to interact with a blockchain node in real-time. It establishes a persistent, bi-directional connection between the client and the node, enabling the client to send requests and receive responses instantly.

WebSocket RPC is commonly used for tasks such as

• submitting transactions

• querying blockchain data,

• subscribing to event notifications.

By leveraging WebSocket RPC, blockchain applications can provide a more responsive and interactive user experience compared to traditional HTTP-based communication.

REST vs WebSocket

WebSocket RPC and REST (Representational State Transfer) are two different approaches to client-server communication. The main differences between them are:

1. Protocol: WebSocket RPC uses the WebSocket protocol, which enables full-duplex, bi-directional communication over a single, persistent connection. REST, on the other hand, typically uses the HTTP protocol and follows a request-response model.

2. Communication Style: WebSocket RPC allows for real-time, event-driven communication, where the server can push updates to the client as soon as they occur. REST is based on a request-response cycle, where the client sends a request and waits for the server's response.
