Examples

Example 1: Real life usecase

Note

The following example is purely fictitious and does not showcase the final product. The sole purpose of this example is to provide a basic workflow on how smart contracts can be used.

Let’s suppose a simple example. A social media website wants to keep track of a like counter and wants to use the Avian blockchain to keep track of a decentralized matter.

This would be their workflow:

  • Install the Avian wallet

  • Write code

  • Deploy code to Avian blockchain

  • Hook website to call flight plan function

Let’s write the smart contract

Lua code

How to call the functions?

Use this RPC method:

call_flightplan [flight plan name] [function name] [args]

RPC Figure 1 - An example of calling an Avian flight plan via the RPC

How would you show the likes on the website?

Since a new RPC call will allow users to call flight plan functions, any RPC library should work. This means almost any programming language that supports HTTP calls can use Avian smart contracts. Figure 2 will show a simple example in React which is a popular frontend framework.

Example 2: Creating a DNS system

Note

This example is theoretical and only serves to show how flight plans can be coded.

Let’s create a DNS system using Avian flight plans! Our current DNS is used to convert domain names such as “avn.network” to their correct IP address. Unfortunately, DNS is centralized, so let’s take the opportunity to use assets and smart contracts to create a basic DNS system in Avian.
