The roadmap for understanding WTF blockchain developer is. I'm curious if this technology can find its application in the gambling industry.

Vitto wrote something about web 3. Here's my filtered version.

Decentralized applications

What is a Decentralized Application?

  • frontend
  • Solidity/Solana backend, built on top of a blockchain

Specifically Ethereum blockchain. Ethereum is software running on a network of computers that ensures the replication and processing of small programs called Smart Contracts

A Smart Contract is software stored on a blockchain-based platform, that automatically executes an agreement. It is written in Solidity, Rust, or Vyper (Solidity but in Py flavor)

Solidity is a high-level, contract-oriented programming language to write smart contracts, allowing programmers to write self-executing code that powers blockchain DApps.


Choose between two JavaScript libraries to connect to local or remote blockchain:

Truffle - a development environment, testing framework, and asset pipeline for any EVM Blockchain. Ganache, part of the Truffle suite, is a tool solely built to test Ethereum contracts locally.


Remix is a Solidity IDE used to write, compile and debug Solidity code. Contract development in Remix. It has plugins.


Here are some project ideas rewritten from.


There is registration period and voting period. Anyone can register. Anyone can vote. All votes immediately visible, a vote cannot be changed.

Very good practive for roulette/horse racing app, where also there is a period for bets and show time later.

Before writing these projects, the architecture shouold be reviewed in terms of "Understanding and Discovering Attacks on Ethereum Decentralized Applications"

Also worth mentioning decentralized websites by - new way of web browsing.
