For Programmable Blockchains

Components Involved:

  1. Fiamma: The core network handling the verification of ZKPs.

  2. Data Availability (DA) Layer: Stores proof-related data securely.

  3. Ethereum: Executes smart contracts to verify data and signatures.

  4. Various ZKP Systems: Includes Boojum, Plonky2, Circle Stark, and others.

Steps:

Step 1: Proof Generation and Submission

  • ZKP Systems (Boojum, Plonky2, Circle Stark, etc.):

    • Various ZKPs are generated by different systems and submitted to the Fiamma network.

  • Fiamma:

    • Generate BLS Signature: Fiamma generates a BLS signature which includes data_hash, proof_hash, result, and new_state.

Step 2: Storing Data in DA Layer

  • Fiamma to DA Layer:

    • Send Data: Fiamma sends the transaction data (txdata), proof, and result to the DA layer for storage.

  • DA Layer:

    • Store Data: The DA layer securely stores the received data ensuring its availability and integrity.

Step 3: Retrieving Data from DA Layer

  • DA Layer to Ethereum:

    • Send Tuple Data: The DA layer sends a tuple of data (tuple_data{data_hash, proof_hash, result, new_state}) to Ethereum for further verification.

  • Ethereum:

    • Check Contract: Ethereum smart contracts retrieve and verify the data from the DA layer. The contracts perform checks on DA Check and Sig Check.

Step 4: Verification on Ethereum

  • Ethereum Smart Contracts:

    • Check Contract Execution: The smart contracts on Ethereum execute the checks (DA Check and Sig Check) to verify the data and signatures.

    • Final State Update: Once the checks are successful, the final state is updated on the Ethereum network.
