Demystifying the EVM: a practical guide for devs (with real examples)

Hey everyone,
This post is a guide that turns EVM internals from “I think I get it” into “I can actually use this.” It focuses on how the EVM actually executes your Solidity, how gas is consumed at the opcode level, and what really happens during calls.

Highlights:

• model of gas, why it exists, and how costs accrue at the opcode level
• What smart contracts are (in practice) and how the EVM enforces determinism
• Architecture walkthrough: stack, memory, storage, calldata.
• Function selectors and ABI calldata explained with example
• Mini example: from Solidity source to bytecode

Curious how others explain EVM internals to new teammates and what analogies or gotchas do you use?
