Blockchain Specialist Course

Lesson 1 • Cryptographic Primitives for Blockchain

Introduces hash functions, digital signatures, and public-key cryptography. These tools underpin every transaction and block validation mechanism.

Lesson 2 • Types of Blockchain Networks

Distinguishes public, private, and consortium blockchains by access control and governance. Guides selection of network type for specific use cases.

Lesson 3 • Block and Chain Data Structure

Examines how individual blocks are constructed and linked via cryptographic hashes. Students trace how tampering with one block invalidates the entire chain.

Lesson 4 • Consensus Mechanisms Overview

Surveys Proof of Work, Proof of Stake, and delegated variants. Connects consensus choice to network security, energy use, and throughput trade-offs.

Lesson 1 • Transaction Validation and Finality

Traces a transaction from broadcast through block inclusion to finality. Covers confirmation thresholds and probabilistic vs. deterministic finality.

Lesson 2 • Wallet Types and Architecture

Compares custodial, non-custodial, hot, and cold wallet designs. Connects wallet choice to security posture and operational requirements.

Lesson 3 • Cryptographic Key Management

Covers secure generation, storage, and rotation of key pairs. Proper key management prevents asset loss and unauthorized access.

Lesson 4 • Transaction Construction and Signing

Explains UTXO and account-based transaction models, then walks through signing workflows. Students build and verify raw transactions manually.

Lesson 1 • Writing and Testing Contract Logic

Applies unit and integration testing patterns to validate contract behavior before deployment. Students achieve high test coverage on sample contracts.

Lesson 2 • Smart Contract Programming Language

Introduces the primary high-level language for EVM-compatible contracts, covering syntax, types, and control flow. Students write basic contracts from scratch.

Lesson 3 • Contract Deployment and Upgradability

Covers deployment to test and main networks, and introduces proxy patterns for upgradable contracts. Students deploy and verify contracts on a public testnet.

Lesson 4 • Development Environment Setup

Configures local and cloud-based toolchains for compiling, testing, and deploying contracts. Reduces friction in the development feedback loop.

Lesson 1 • Post-Deployment Monitoring and Incident Response

Sets up on-chain monitoring alerts and defines an incident response playbook for live contracts. Minimizes damage when vulnerabilities are discovered post-launch.

Lesson 2 • Secure Coding Patterns

Presents checks-effects-interactions, pull payment, and role-based access patterns as defenses. Students refactor vulnerable contracts using these patterns.

Lesson 3 • Static and Dynamic Analysis Tools

Demonstrates automated scanners and fuzz testing tools for detecting vulnerabilities at scale. Integrates tooling into the development pipeline.

Lesson 4 • Common Vulnerability Classes

Catalogs reentrancy, integer overflow, access control flaws, and other critical vulnerability types. Each class is demonstrated with a vulnerable code example.

Lesson 1 • Tokenomics Design Principles

Models supply schedules, emission curves, vesting, and incentive alignment for sustainable token economies. Students critique and redesign a flawed tokenomics model.

Lesson 2 • Token Classification and Use Cases

Distinguishes utility, governance, security, and non-fungible tokens by function and regulatory implication. Frames token design decisions around intended behavior.

Lesson 3 • Fungible Token Standards

Implements the dominant fungible token interface standard, covering transfer, approval, and allowance functions. Students deploy a fully compliant fungible token.

Lesson 4 • Token Launch and Distribution Strategies

Compares fair launch, airdrop, liquidity bootstrapping, and private sale distribution methods. Evaluates each for decentralization and community alignment.

Lesson 1 • Oracle Integration and Off-Chain Data

Explains how oracles bridge real-world data to smart contracts and the trust assumptions involved. Students consume a price feed in a sample contract.

Lesson 2 • User Experience and Wallet Onboarding

Addresses friction points in dApp onboarding, including gas abstraction and account recovery. Improves adoption by reducing technical barriers for end users.

Lesson 3 • Blockchain Interaction Libraries

Covers JavaScript and Python libraries for reading state, sending transactions, and listening to events. Students integrate a library into a sample front end.

Lesson 4 • dApp Architecture Patterns

Maps the layers of a decentralized application: front end, wallet connection, smart contracts, and storage. Establishes design principles for each layer.

Lesson 1 • Decentralized Lending and Borrowing

Covers collateralization ratios, interest rate models, and liquidation mechanics in lending protocols. Students simulate a borrow position and liquidation scenario.

Lesson 2 • Automated Market Maker Mechanics

Explains constant-product and concentrated liquidity AMM formulas and their impact on price and slippage. Students calculate swap outputs and impermanent loss.

Lesson 3 • DeFi Risk Assessment Framework

Structures protocol risk evaluation across smart contract, liquidity, oracle, and governance dimensions. Students score a live protocol using the framework.

Lesson 4 • Yield Optimization Strategies

Analyzes yield farming, liquidity mining, and auto-compounding vault strategies. Students compare risk-adjusted returns across protocol combinations.

Lesson 1 • Regulatory Compliance and Risk Management

Addresses anti-money-laundering controls, data privacy obligations, and audit trail requirements in blockchain deployments. Maps compliance controls to technical features.

Lesson 2 • Scalability and Layer-2 Solutions

Analyzes state channels, rollups, and sidechains as throughput scaling approaches. Students select and justify a scaling solution for a given workload.

Lesson 3 • Enterprise Integration Patterns

Covers API gateway, event-driven, and middleware integration patterns for connecting blockchain to legacy systems. Students design an integration architecture diagram.

Lesson 4 • On-Chain Governance Design

Models voting mechanisms, proposal lifecycles, and parameter governance for decentralized and consortium networks. Evaluates governance attack scenarios.

Lesson 5 • Business Case and ROI Evaluation

Builds a structured business case by quantifying cost reduction, process efficiency, and trust gains from blockchain adoption. Students present a go/no-go recommendation.
