1 · Foundations
Ledgers, hashing, keys, transactions and consensus.
- 1. What Is a Blockchain?Blocks, hashes and the append-only ledger: why a chain of hashed blocks makes history hard to rewrite.8 min · 4 MCQs
- 2. Keys, Addresses & WalletsPrivate keys, public keys, seed phrases and how the same 12 words can control EVM, SVM, BTC and DOGE accounts.10 min · 4 MCQs
- 3. Transactions, Nonces & FeesHow a signed transaction travels from your wallet to a block, and what you actually pay for.9 min · 4 MCQs
- 4. Consensus & FinalityProof of Work, Proof of Stake, reorgs and how many confirmations are enough.8 min · 4 MCQs
- 5. Smart Contracts & TokensEVM bytecode, ABIs, ERC-20/721, Solana programs and accounts — and where your staking contract fits.10 min · 4 MCQs
- 6. Security, Testnets & Safe HabitsFaucets, testnet workflow, signature phishing, approvals and the habits that keep student wallets safe.9 min · 4 MCQs
2 · Protocols & smart contracts
Ethereum, the EVM, Solidity and token standards.
- 7. Bitcoin Deep Dive: UTXOs, Script, Ordinals & RunesHow Bitcoin's UTXO model, Script locks and Taproot witness data enable inscriptions and Runes fungible tokens.11 min · 5 MCQs
- 8. Solidity for the EVMContract structure, storage vs memory, events and the ABI, and the safety patterns behind the SimpleStaking contract.11 min · 5 MCQs
- 9. Rust for Solana ProgramsOwnership in one pass, stateless programs with separate accounts, PDAs, rent and how Anchor removes boilerplate.11 min · 5 MCQs
- 10. Clarity on StacksA decidable, interpreted smart-contract language: LISP syntax, explicit responses, post-conditions and Bitcoin settlement.10 min · 5 MCQs
- 11. Go for Blockchain InfrastructureWhere Go lives in the stack: clients like go-ethereum, Cosmos SDK chains, indexers, bots and RPC tooling.10 min · 5 MCQs
- 12. JavaScript & TypeScript for dAppsWallet providers, ethers.js contract objects, BigInt maths and typed async transaction handling — the code behind the staking sandbox.11 min · 5 MCQs
3 · Scaling, DeFi & security
Layer 2s, DeFi, NFTs, DAOs, security and auditing.
- 13. Layer 2 Scaling & RollupsWhy base layers are slow, and how optimistic and zero-knowledge rollups inherit L1 security while batching execution off-chain.11 min · 5 MCQs
- 14. DeFi Primitives: AMMs, Lending & StablecoinsHow constant-product pools price trades, how overcollateralized lending markets work, and the mechanics behind different stablecoin designs.12 min · 5 MCQs

- 16. DAOs & On-Chain GovernanceHow token-weighted voting, timelocks and delegation let a community steer a protocol's treasury and parameters without a central operator.10 min · 5 MCQs
- 17. Wallet Security & Key ManagementHot vs cold storage, multisig and social-recovery wallets, and the phishing and signing tricks that drain self-custodied funds.10 min · 5 MCQs
- 18. Smart Contract Auditing BasicsA practical checklist mindset: reentrancy, access control, integer edge cases, oracle trust and the layered process real audits follow.12 min · 5 MCQs
