halo2

What problem does it solve?

This Skill simplifies the complex process of building and debugging zero-knowledge PLONK circuits using the halo2_proofs Rust library, enabling developers to create verifiable computations efficiently.

Core Features & Use Cases

• Circuit Definition: Define custom circuits using the Circuit trait, specifying gates, columns, and constraints.
• Constraint System Management: Configure advice, fixed, and instance columns, along with selectors and lookup arguments.
• Debugging with MockProver: Utilize MockProver to test circuit logic and identify constraint violations without generating full proofs.
• Use Case: A developer needs to implement a zero-knowledge proof for a private transaction system. They can use this Skill to define the circuit logic, assign witnesses, and debug the constraints using the mock prover before deploying to a live network.

Quick Start

Use the halo2 skill to define a new PLONK circuit for a simple multiplication gate.
