Cost Estimator

The Cost Estimator is a powerful tool that allows you to estimate proving costs for op-succinct without actually generating proofs. This helps you optimize your proof generation strategy by identifying potential causes of unexpected costs.

Overview

The cost estimator simulates the proof generation process and provides detailed metrics including:

• Total instruction count
• Oracle verification costs
• Derivation costs
• Block execution costs
• Blob verification costs
• SP1 gas usage
• Transaction counts and EVM gas usage
• Various precompile cycles (BN pair, add, mul, KZG eval, etc.)

Setup

Before running the cost estimator, you need to set up a .env file in the project root directory with the following RPC endpoints:

L1_RPC=<YOUR_L1_RPC_ENDPOINT>
L1_BEACON_RPC=<YOUR_L1_BEACON_RPC_ENDPOINT>
L2_RPC=<YOUR_L2_RPC_ENDPOINT>
L2_NODE_RPC=<YOUR_L2_NODE_RPC_ENDPOINT>

Usage

To run the cost estimator, use the following command:

RUST_LOG=info cargo run --bin cost-estimator -- \
    --start <START_BLOCK> \
    --end <END_BLOCK> \
    --batch-size <BATCH_SIZE>

Example:

RUST_LOG=info cargo run --bin cost-estimator -- \
    --start 2000000 \
    --end 2001800 \
    --batch-size 1800

For the best estimation, use a range bigger than the batcher interval with the batch size equal to the range.

Output

The execution report is saved in the execution-reports/{chain_id}/{start_block}-{end_block}-report.csv directory.
