Course Outline

Day 1: Web3 Architecture & The SCF Use Case

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

Day 2: Smart Contract Engineering for Finance

  • Solidity/Chaincode Deep Dive: Examining data structures, mappings, and modifiers.
  • Coding the "Invoice": Creating a Struct to model an invoice, including state variables for approval status.
  • Automating Liquidity: Implementing functions for requestEarlyPayment(), approveInvoice(), and settlePayment().
  • Lab: Developing and unit testing a basic Factoring Smart Contract.

Day 3: Integration, Security & Deployment

  • The Oracle Problem: Strategies for securely integrating shipping data (e.g., "Goods Received") into Smart Contracts to initiate payments.
  • Security Best Practices: Identifying common vulnerabilities (such as Reentrancy and Integer Overflow) and utilizing audit tools (MythX/Slither).
  • The Dapp Frontend: An overview of connecting React/Next.js frontends to contracts using Ethers.js or Web3.js.
  • Project: Deploying the SCF contract to a testnet and interacting with it via a script.
