Foundations of Cryptography and Distributed Systems
2-3 weeksLearn the fundamental building blocks of blockchain: cryptographic hash functions (SHA-256), public-key cryptography, digital signatures, and the basics of peer-to-peer distributed networks. Understand how these components work together to create trustless systems.

Understanding Bitcoin and Blockchain Architecture
3-4 weeksStudy how Bitcoin works in detail: the structure of blocks, Merkle trees, the UTXO model, mining and Proof of Work, difficulty adjustment, the mempool, and the Bitcoin halving cycle. Run a Bitcoin testnet node to experience the technology firsthand.
Ethereum and Smart Contract Programming
4-6 weeksLearn the Ethereum Virtual Machine (EVM), account model vs. UTXO model, gas mechanics, and the Solidity programming language. Write, test, and deploy basic smart contracts on test networks. Understand the ERC-20 and ERC-721 token standards.
Consensus Mechanisms and Network Security
2-3 weeksDeep dive into various consensus algorithms: Proof of Work, Proof of Stake, Delegated Proof of Stake, Proof of Authority, and Byzantine Fault Tolerance. Analyze their trade-offs in terms of security, decentralization, scalability, and energy consumption. Study common attack vectors including 51% attacks, Sybil attacks, and eclipse attacks.
Decentralized Finance (DeFi) Ecosystem
3-4 weeksExplore the DeFi landscape including decentralized exchanges (Uniswap, Curve), lending protocols (Aave, Compound), stablecoins (USDC, DAI), yield farming, liquidity mining, and the concept of composability. Understand the risks including smart contract vulnerabilities, impermanent loss, and liquidation cascades.
Advanced Topics: Scaling, Privacy, and Interoperability
3-4 weeksStudy Layer 2 scaling solutions (rollups, state channels, sidechains), cross-chain bridges and interoperability protocols (Cosmos IBC, Polkadot), privacy-focused technologies (zero-knowledge proofs, zk-SNARKs, zk-STARKs), and the trade-offs involved in blockchain scaling.
Regulation, Economics, and Real-World Applications
2-3 weeksExamine the regulatory landscape for cryptocurrencies across jurisdictions, tokenomics and cryptoeconomic design, DAOs and on-chain governance models, and real-world applications in supply chain, healthcare, identity, and voting. Analyze the economic implications of programmable money and CBDCs.
Building and Deploying Blockchain Projects
4-6 weeksApply your knowledge by building a complete decentralized application. Use development frameworks like Hardhat or Foundry, integrate with front-end libraries (ethers.js, wagmi), deploy smart contracts to mainnet, and conduct security audits. Contribute to open-source blockchain projects to deepen expertise.
