How to download PIE and PROOF files from your Atlantic queries

Downloading PIE & PROOF

Integrity allows you to verify STARK proofs on Starknet. It also registers all verified proofs in its storage, so other Cairo contracts can access them. It is crucial to understand how programs are stored inside Integrity’s Fact Registry.

Integrity Verifier

Proof verification with [Integrity](/atlantic/integrity-verifier) using `dynamic` or `all_cairo` layouts.

Dynamic Layout on L2

Contract Addresses

Trace generation is a process of running Cairo program on given inputs and generating `pie.zip` file. Pie represents exact execution of Cairo program and is necessary for proof generation.

Trace Generation

Proof generation is a process of converting `pie.zip` file into STARK proof (`proof.json` file), which can be later verified at a lower cost compared to running the program itself. Proof can be generated with either Starkware's Sharp Prover or Stone Prover hosted by Herodotus.

Proof Generation

Trace Generation and Proof Generation

This endpoint allows for proof generation and verification for Layer 1 (L1) in a single request. It takes a `pie.zip` file, generates a proof and verifies it in a smart contract on the Ethereum blockchain. This allows for secure on-chain verification of zero-knowledge proofs at L1 suitable for high security use cases but with potentially higher gas costs.

L1 Proof Generation Verification

You can verify your STARK proofs on Starknet (L2) using [Integrity verifier](/atlantic/integrity-verifier). It is faster and much cheaper compared to verifying on L1 and especially useful if you need an interaction with Starknet contracts.

L2 Proof Verification

L2 Proof Generation Verification

These endpoints provide a complete workflow for generating trace, proof and verifying the proof on L1 and L2 respectively.

L1/L2 Atlantic Query

This endpoint allows you to submit a compiled Cairo program to the program registry. Once submitted, the system registers the program and generates a unique program hash. This hash can be used for future proof and trace generation requests without needing to re-upload the program file, making the process more efficient for repeated queries.

Submit Program To Program Registry

Handles batch queries for interacting with storage slot data.

Submit a batch query

Allows you to estimate the cost of a batch query before submitting it, the body is the same as the submit batch query body, use that endpoint for reference on how to build the body.

Estimate batch query cost

Provide the batch query id to get the status of your batch query.
