What is a JSON-RPC node?

JSON RPC node is a blockchain server using the JSON-RPC protocol to process the command and return the data encoded in JSON. It allows a client to communicate with the blockchain in a simple text-based format.

What is JSON-RPC used for?

Developers can integrate Node.js with JSON-RPC to create decentralized applications (dApps) that interact with various blockchain networks. The lightweight, stateless nature of the protocol makes it ideal for quick and frequent interactions between dApps and cryptocurrency networks.

What is the difference between JSON-RPC and GraphQL?

JSON-RPC lets clients send requests to servers and get back responses. This simplicity makes it straightforward and easy to use. Unlike a node using JSON-RPC, which handles one request at a time, GraphQL servers allow for more complex, structured, and flexible queries.

JSON-RPC vs Websocket: How are they different?

JSON-RPC is request-response based, ideal for independent actions. WebSocket, on the other hand, maintains a continuous connection, making it better suited for live updates or streaming. Both WebSockets and JSON-RPC in Node.js can be combined depending on the use case.

JSON-RPC Nodes

JSON-RPC is a remote procedure call (RPC) protocol encoded in JSON, facilitating communication between clients and servers. It enables executing commands and retrieving data on blockchain nodes, supporting methods for querying balances and sending transactions. JSON-RPC is lightweight, stateless, and commonly used in decentralized applications (dApps) for interaction with blockchain networks.
