“Blockchain & Web3: Absolute Beginner’s Guide” is a practical, jargon-light orientation to the world of blockchain—built for newcomers who want clarity fast. Instead of drowning you in buzzwords, we walk through the core building blocks step-by-step: what a block is, how transactions work, why consensus matters, how wallets sign messages, and where fees (“gas”) fit in. You’ll see how Bitcoin and Ethereum differ at a conceptual level, what Layer-2 networks are trying to solve, and how a basic on-chain app (dApp) fits together.

This course is deliberately hands-on. You’ll install a non-custodial wallet, connect to a public testnet (no real money), request faucet funds, send a transaction, and verify it on a block explorer. We’ll also decode the transaction page—nonce, gas price, status, logs—so you can read on-chain activity with confidence. Short “knowledge checks” keep you on track, and two lightweight labs give you a real sense of how Web3 works day-to-day.

Because this Academy is part of Imali Wealth Group, examples draw from African fintech and real projects you’ll meet later in the Academy: AgriSmart Hubs (farm-to-market value chains), carbon credit tokenization and MRV, and payments/wallet experiences. You’ll leave with a clear mental model of the ecosystem and a map of next steps—developer, product, security/audit, enterprise (Hyperledger), or compliance/regulatory paths.

What you’ll be able to do by the end

• Explain blockchain and Web3 in plain language to a colleague or client.

• Safely use a wallet on a testnet and send a transaction end-to-end.

• Read a block explorer page and interpret the key fields.

• Understand the differences between Bitcoin (UTXO) and Ethereum (account model) at a high level.

• Describe what L2s/rollups are solving (scalability, cost) without hype.

• Identify which Imali Academy track fits your goals and how to proceed.

What this course is not

• It’s not a coding bootcamp (that starts in Solidity 101).

• It’s not investment advice.

• It’s not a legal/compliance deep dive (that’s a separate track).
