Hello Word smart contract for TON (FreeTON)

One of the interesting topics that I would like to talk about today is the programming of smart contracts. For the language in which we will program our smart we will take Solidity, and as a platform we will use FreeTON

We will not dive into blockchain technology today, because there are already many articles about it. Therefore, consider a simple smart contract in the following order:

1. Where to begin;

   
   
   
   
   

2. "Hello World";

   
   
   
   
   

3. TON features of the Hello World smart contract;

   
   
   
   
   

4. Links to additional information.

To obtain basic information about the TON project, you can go to the official website of the Pavel and Nikolai Durov project . Unfortunately, due to difficulties with regulators in the United States, the project, as part of Telegram, has been closed. The project that continued on its way became an independent community . And here is the developer documentation . Well, github .
