Folder Structure

Basic Healthy Folder Structure of Poseidon

Once --circuit-setup is done you will get the below folder structure.

circom folder will not be there if you have already got circom installed earlier - so nothing to worry !!

poseidon/
│── circom
│── circomlib/            # Standard library for Circom components
│── circuits/             # Where your .circom files go
│   └── circuit1.circom   # A starter circuit with boilerplate
│── requirements.txt
│── poseidon.py             

The Poseidon project is organized to streamline zk-SNARK development:

• circom/ – (Optional) Place to store local circom binary or related builds.

• circomlib/ – Standard Circom library, includes reusable components like Poseidon hash, Merkle tree, etc.

• circuits/ – Your working directory for writing circuits in .circom files.

  • circuit1.circom – A basic starter circuit with template logic to begin with.

• requirements.txt – Python dependencies needed by poseidon.py.

• poseidon.py – Main CLI script to automate setup, compile, prove, and verify workflows.

This layout ensures everything is in place to begin writing and testing zero-knowledge circuits efficiently.
