Course Outline

Day 1: Web3 Architecture & The SCF Use Case

  • Cryptographic Primitives: Exploration of hashing, Merkle Trees, and Public/Private Key Cryptography within the context of enterprise identity (DID).
  • Consensus Mechanisms: In-depth analysis of PoS (Proof of Stake) versus PoA (Proof of Authority) for consortium chains.
  • The SCF Engineering Challenge: Mapping the "Reverse Factoring" workflow to a state-machine diagram.
  • Lab: Establishing the local development environment (Hardhat/Truffle/Ganache) and connecting to a testnet.

Day 2: Smart Contract Engineering for Finance

  • Solidity/Chaincode Deep Dive: Examination of data structures, mappings, and modifiers.
  • Coding the "Invoice": Creating a Struct to define an invoice entity and state variables for tracking approval status.
  • Automating Liquidity: Developing functions for requestEarlyPayment(), approveInvoice(), and settlePayment().
  • Lab: Writing and performing unit testing on a foundational Factoring Smart Contract.

Day 3: Integration, Security & Deployment

  • The Oracle Problem: Strategies for securely importing shipping data (e.g., confirmation of "Goods Received") into the Smart Contract to trigger payments.
  • Security Best Practices: Analysis of common vulnerabilities (such as Reentrancy and Integer Overflow) alongside audit tools like MythX/Slither.
  • The Dapp Frontend: A concise overview of connecting a React/Next.js frontend to the contract using Ethers.js or Web3.js.
  • Project: Deploying the SCF contract to a testnet and interacting with it via script.
