AT A GLANCE

What are crypto & Web3?

Cryptocurrency is a digital asset issued and transferred on a blockchain — a tamper-resistant, decentralised ledger. It lets you store and move value without a central administrator, and the broader system of such apps is called Web3. Leading examples are Bitcoin (BTC), Ethereum (ETH) and Solana (SOL). WEB3DOJO is a learning dojo that explains it all, from basics to practice, neutrally and with sources.

FAQ

What is cryptocurrency?

A digital asset issued and moved on a blockchain. It lets you store and transfer value with no central administrator — Bitcoin and Ethereum are the best-known examples.

What is Web3?

A vision of the web built on blockchains, where users hold their own assets and data instead of depending on a single company. It spans crypto, NFTs and DeFi.

Where should I start?

Learn blockchain basics first, then how to use a wallet and an exchange, then safety and taxes. The WEB3DOJO roadmap walks you through it in order.

Is crypto safe?

The technology is robust, but human risks — scams, sending to the wrong address, losing your keys — are real. Start small, use two-factor authentication and back up your wallet.
