Blockchain & Web3: Absolute Beginner’s Guide
- Description
- Curriculum
- Reviews
“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).
-
1Lesson 1 — What is Web3? Narratives vs realitiesText lesson
Estimated time
15–18 minutes reading + 3–5 minutes activity
Learning outcomes
After this lesson, you can:
-
Define Web3 in one–two sentences without buzzwords.
-
List three common Web3 narratives and state the realistic status of each.
-
Identify one credible Web3 use case in your own context.
-
-
2Lesson 2 — Centralized vs Decentralized (very high level)20 - 30 min
Goal: Understand the practical differences between centralized and decentralized systems so you can choose the right approach for real products.
Learning outcomes
After this lesson, you can:
-
Define centralized vs decentralized in simple language.
-
List 4–5 everyday trade-offs (speed, control, transparency, reliability, cost).
-
Choose when a centralized, decentralized, or hybrid model makes sense.
-
-
3Lesson 3 — Real-world Use Cases30–40 minutes
(payments/remittances, AgriSmart supply chains, carbon/MRV, identity)
Goal: Understand four credible use cases and the minimum viable architecture (MVA) for each—what must live on-chain vs. what should remain off-chain.
Learning outcomes
By the end you can:
-
Explain how Web3 helps payments, supply chains, carbon markets, and identity.
-
Identify “must-be on-chain” components vs “better off-chain” services.
-
Sketch a 3-line MVA brief for one use case, including top risk.
-
-
4Lesson 4 — Wallets & Safety60–75 minutes
Goal: Install a non-custodial wallet, add a test network, follow seed-security best practices, and learn to recognize/revoke risky approvals.
Learning outcomes
By the end you can:
-
Explain keys, seed phrases, addresses in plain language.
-
Install a wallet, add a public testnet, get faucet funds, and confirm your balance.
-
Describe token approvals/allowances and how to revoke them.
-
Complete a step-by-step safety checklist (Lab 1).
-
-
5Lesson 5 — Tokenomics 10145–60 minutes
Goal: Understand coins vs tokens, token roles (utility/governance/fees/rewards), supply & emissions, vesting, and how to align incentives without creating perverse outcomes.
Learning outcomes
By the end you can:
-
Distinguish coins (native) vs tokens (issued by contracts).
-
Explain utility, governance, rewards, and collateral roles.
-
Read a basic emissions schedule and describe vesting/treasury.
-
Sketch a 12-month emissions plan and call out key risks.
