Beginners and students curious about blockchain who want real understanding, not hype, and a first practical project to show.
Beginner level
Blockchain and Web3 Engineering
Build a Blockchain and Your First Smart Contracts
Understand how blockchains really work by building one in Python: hashing, digital signatures, blocks, proof of work, wallets and transactions. Then learn Ethereum accounts and gas, deploy simple Solidity contracts with Remix to a test network and learn how to spot scams and risks.

At a glance
Basic Python (functions, classes, dictionaries, lists) and the ability to install packages with pip. No financial knowledge or cryptocurrency is needed, and you will only use free test networks, never real money.
Pass the quizzes, complete the labs and submit your capstone. Everything is checked as you go and your certificate is issued the moment you finish.
What you will be able to do
- 01Explain hashes, digital signatures, blocks, consensus and forks in plain language
- 02Build a working blockchain with proof of work, signed transactions and validation in Python
- 03Describe Ethereum accounts, transactions, gas and how smart contracts differ from ordinary programs
- 04Write, deploy and interact with simple Solidity contracts on a test network using Remix and a wallet
- 05Recognise common scams and risks and discuss regulation and taxation responsibly

What you take away
An internship certificate with your skills on it.
Made for you automatically when you finish the last part, it names the internship programme, the level and the 41 hours, lists what you showed, and carries a number and a QR code. Anyone can check it on the NIBVEDA verification page, and it shows as withdrawn there if it is ever revoked.
- Proof you completed all 41 hours of this internship programme
- An Internship badge for your profile, CV or portfolio
- Not a job, a stipend or an academic degree, and it says so
Keep building.
3 programmes in this track, from beginner to expert. Buy the learning path and save 15%.
Write production-style Solidity: storage, inheritance and custom errors, then test with Hardhat, build ERC-20, ERC-721 and staking contracts with OpenZeppelin, learn gas and design patterns, build a dApp front end with ethers.js and deploy and verify to a public test network.
- Solidity
- Hardhat
- OpenZeppelin
Learn how smart contracts are broken and how professionals defend them: vulnerability classes, Foundry fuzzing and invariant testing, DeFi mechanics and oracle attacks, upgradeability and cross-chain risk, static and formal analysis, and the audit process from scoping to a written report.
- Smart contract security
- Foundry fuzzing and invariants
- DeFi protocol analysis

Quick answers.
The policies have the full detail.
Is this a real internship?
It is a virtual internship programme: a structured, self-paced course built around a real project, with checked assessments and a certificate. It is not employment, it does not carry a stipend and it is not an academic or AICTE-approved qualification. What it gives you is verified, project-based evidence of skills.
How does self-paced work?
You start when you like and move at your own speed. Each part unlocks when you finish the one before it. There are no live classes and no deadlines. Your access is shown on each programme page.
How is my work checked?
Quizzes are marked as soon as you submit them. Labs use a tick-list of tasks. Intermediate and Expert programmes finish with a capstone that the NIBVEDA team reviews and either accepts or sends back with comments.
Can I get a refund?
Please read the refund policy before you buy. It explains when a refund is possible.
