What is JSON-RPC ❓ Definition, Work, Comparison

An Overview to JSON: What is it and How it works?

What is JSON RPC?

  • It defines the data processing related constraints over a network.
  • Its light construction and quick processing are the features that make it suitable to initiate data transfer with Ethereum nodes.
  • As this protocol is transport-agnostic protocol, it can utilize sockets as well as HTTP for interacting.
  • It’s a really good choice for developing Ethereum-based solutions that utilize Blockchain.
  • JSON-RPC 1.0 lacked utility at multiple fronts. Especially the absence of names parameters and error-message explanations caused troubles more than one’s expectations. It was more of a peer-to-peer communication method.
  • The updated specification, JSON RPC 2.0, was highly advanced and solved the lacunas of the previous version. v1.0 was replaced by client-server in version 2.0. The transport means dependency was achieved in version 2.0.

How to use JSON RPC?

  1. Method: It refers to the stringthat will be petitioned while calling a method. There is a set of reserved names with prefix ‘rpc’, meant for internal RPC calls. One cannot use these method names causally.
  2. Params: The second element of the JSON-RPC that could be an Object or an Array, featuring value of the parameter to be carried forward. params are not invoked in every call.
  3. ID: The non-fraction or string number regularly deployed to maintain the balance between response and requests. In the absence of a response towards a request, the ID will be removed automatically.
  1. Result is the first and foremost part of response that carries the data returned by invoked method. It is often called JSON-stat and will remain absent if an error occurs.
  2. Error, the second member, will come into being if a problem occurs while invoking the process. Code and message are the essential parts of this member.
  3. A response ID refers to the request against which a response is taking place. For situations demanding no responses, JSON-RPC makes use of notifications that is a version of a request having no ID. In v1, notification ID is forwarded as null while in the case of version 2.0 it’s completely omitted.
