Learning & debugging EVM bytecode
The EVM is easiest to understand when you can watch it run. Zig EVM pairs an interactive playground with a detailed blog so you can see — and reason about — every opcode, gas charge and stack change.
The playground
The browser playground is a bytecode editor with real-time disassembly, stack visualisation and step-by-step execution tracing. Paste bytecode or write it by hand, then watch how each instruction moves the stack, touches memory and consumes gas — no install, no node required.
The blog
Deep, practical write-ups on EVM internals and Zig systems programming:
- How the Ethereum Virtual Machine works — the architecture deep dive.
- EVM opcodes explained — a complete reference with examples.
- Understanding EVM gas — metering and optimisation.
- EVM bytecode from Solidity to opcodes — the compilation pipeline.
- Debugging with transaction tracing — finding what went wrong.
Why it clicks faster
Because the playground and the docs run on the same MIT-licensed engine described in how it works, what you read maps directly onto what you can run. When you are ready to go deeper, the whole implementation is on GitHub.
FAQ
Do I need to install anything to try Zig EVM?
No. The playground runs in the browser — edit bytecode and watch the disassembly, stack and execution trace update in real time, with no local setup.
Where can I learn how the EVM actually works?
The blog covers EVM internals opcode by opcode: how the EVM works, EVM opcodes explained, understanding EVM gas, bytecode from Solidity to opcodes, storage layout, call types, precompiles and more.
