Fig2. The general flow of applications on Bitcoin

Components Involved:

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

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

3. Bitcoin: Executes scripts to verify data and signatures.

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

Steps:

Step 1: Proof Generation and Submission

• ZKP Systems (Fflonk, Boojum, Stark, etc.):

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

• Fiamma:

  • Generate Schnorr Signature: Fiamma generates a Schnorr 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 Bitcoin:

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

• Bitcoin:

  • Check Script: Bitcoin executes scripts to verify the data and signatures.

Step 4: Verification on Bitcoin

• Bitcoin Scripts:

  • Check Script Execution: The scripts on Bitcoin perform checks on 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 Bitcoin network.

Step 5: Kick off Transaction

• Fiamma:

  • Kick off Transaction: If necessary, Fiamma initiates the transaction based on the verified data and results.
