9.5 Smart Contract Security

Role at Stage 9: AI Security, Blockchain, and ZKML

Recognize common contract vulnerabilities and design AI-to-chain permissions safely. This part is one capability inside the stage. It should leave behind an artifact, measurements, and a short explanation of failure modes.

Explanation

This part has 3 sub-parts because the topic needs that many learning units to feel natural. Some stages have more parts and some have fewer; the structure follows the topic, not a fixed template.

Sub-Parts

Sub-part folder	What it explains
9.5.1 Reentrancy and External Calls	Reentrancy and External Calls is the working skill inside Smart Contract Security that helps you build the stage artifact, A threat model, red-team report, smart contract security lab, and tiny ZKML or verifiable computation demo, while collecting enough evidence to trust the result.
9.5.2 Access Control Bugs	Access Control Bugs is the working skill inside Smart Contract Security that helps you build the stage artifact, A threat model, red-team report, smart contract security lab, and tiny ZKML or verifiable computation demo, while collecting enough evidence to trust the result.
9.5.3 MEV Front Running and Oracle Risk	MEV Front Running and Oracle Risk is the working skill inside Smart Contract Security that helps you build the stage artifact, A threat model, red-team report, smart contract security lab, and tiny ZKML or verifiable computation demo, while collecting enough evidence to trust the result.

What a Person Who Masters This Part Can Do

• Explain how Smart Contract Security supports a threat model, red-team report, smart contract security lab, and tiny zkml or verifiable computation demo..
• Build and inspect this artifact: Create vulnerable contracts, exploits, and fixes.
• Measure progress with: Track vulnerabilities reproduced, tests added, gas impact, and residual risk.
• Debug at least one failure mode before moving to the next part.

Build and Measure

Build: Create vulnerable contracts, exploits, and fixes.

Measure: Track vulnerabilities reproduced, tests added, gas impact, and residual risk.

Tests

Take one 30-question exam after studying this part. It opens in a new browser tab so the study page stays available.
