✨ Key Takeaways

You've completed the EVM module! Let's review what you've learned about Ethereum's decentralized computer.

⚡

Runs on 10,000+ nodes worldwide. Smart contracts execute identically everywhere—no single point of failure.

📚

LIFO stack (1024 items max). Simple, deterministic, perfect for consensus. PUSH → ADD → POP.

🧩

Stack (fast), Memory (temp), Storage (forever, expensive), Code (immutable).

⛽

Every opcode costs gas. Prevents spam/infinite loops. Storage writes = 20,000 gas. Stack ops = 3 gas.

🔤

Solidity → bytecode → opcodes. EVM executes sequentially: PUSH, ADD, SSTORE. Deterministic results.

🎯

Can compute anything (with enough gas). Loops, recursion, conditionals—full programming power.

💡

Deterministic Execution

Same inputs = same outputs. Critical for consensus across 10,000+ nodes.

🔒

Immutable Code

Once deployed, bytecode cannot change. Trust the code, not the deployer.

💾

Persistent Storage

State changes are permanent on blockchain. User balances never disappear.

⚖️

Gas Metering

Pay-per-computation. Complex operations cost more. Fair resource allocation.
