Where is JSON-RPC used?

How does JSON RPC work?

JSON-RPC works by sending a request to a server implementing this protocol. The client in that case is typically software intending to call a single method of a remote system.

What is REST in web?

Representational state transfer (REST) is a software architectural style that was created to guide the design and development of the architecture for the World Wide Web. In a RESTful Web service, requests made to a resource’s URI elicit a response with a payload formatted in HTML, XML, JSON, or some other format.

Is RPC outdated?

RPC has evolved over the years. Starting off as a synchronous, insecure, request-response system, RPC has evolved into a secure, asynchronous, resilient paradigm that has influenced protocols and programming designs like HTTP, REST, and just about anything with a request-response system.

Is JSON-RPC HTTP?

JSON-RPC is simply a remote procedure call protocol that is used on Ethereum to define different data structures. It also defines the rules on how data structures are processed in the network. Because it is transport-agnostic, you can use it to interact with an ETH node over sockets or HTTP.

What is the use of JSON-RPC?

JSON-RPC is a remote procedure call protocol encoded in JSON. It is a very simple protocol (and very similar to XML-RPC), defining only a few data types and commands. JSON-RPC allows for notifications (data sent to the server that does not require a response) and for multiple calls to be sent to the server which may be answered out of order.

What is the difference between JSON-RPC and XML RPC?

It is similar to the XML-RPC protocol, defining only a few data types and commands. JSON-RPC allows for notifications (data sent to the server that does not require a response) and for multiple calls to be sent to the server which may be answered asynchronously.

What is the cleanest RPC library?

It’s very clean, supports unicode (!) by default, and integrates extremely easily into e.g. python or javascript. And JSON-RPC — which uses JSON for serialization — is probably the simplest, most lightweight, cleanest “ASCII”-RPC out there.
