Blockchaindevelopmenttutorials

Blockchaindevelopmenttutorials is a public repository of blockchain development course materials. Each topic pairs an annotated solution with a code-free, comment-based Architecture scaffold for learners to implement first. Materials cover Ethereum, Solana, CosmWasm and Hyperledger Fabric.

Understand the project

Practical overview

When it fits

Use the relevant ecosystem folder to study its example and try the corresponding Architecture scaffold before checking the solution. Treat the Ethereum materials as conceptual exercises rather than production deployment guidance.

Who it is for

  • Learners practicing blockchain development by writing code from a scaffold before reviewing an annotated solution.
  • Developers comparing smart-contract and chaincode approaches across Ethereum, Solana, CosmWasm and Hyperledger Fabric.

Documented uses

  • Practice implementing a tutorial example before consulting its completed, line-commented solution.
  • Study Ethereum contract-to-DApp concepts, including interaction through Web3.js.
  • Compare account-based state handling in Solana, CosmWasm contract storage and Fabric world-state operations.
Before you choose

Requirements & limits

The repository is public and its metadata specifies the MIT license.

  • Ethereum examples use Solidity ^0.4.x; the repository warns that some patterns are outdated and advises against deploying them to mainnet.
  • Solana, CosmWasm and Hyperledger Fabric materials illustrate different state and execution models rather than one interchangeable contract format.
  • The Fabric example covers creating, reading and transferring assets in world state and is described as a private-blockchain model without gas or tokens.
  • The repository suggests contributing by forking and opening a pull request, and identifies Issues as the preferred channel for questions.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Practice a tutorial using its architecture scaffold

Implement an example from its code-free scaffold, then compare your work with the annotated solution.

Before you start

  • A tutorial topic containing an Architecture folder and a full solution.

Steps

  1. Choose a topic in the repository.

  2. Open its Architecture file, which contains comments without code.

  3. Write the code using that scaffold.

  4. Compare your result with the full solution, which includes line-by-line comments.

Expected outcome

A self-practice attempt checked against the corresponding annotated solution.

Guide limitations

  • Ethereum examples use Solidity ^0.4.x and the corresponding compiler; some patterns are outdated. Do not deploy these contracts to mainnet.
  • The repository describes tutorial materials, not a tested course-generation workflow.
