Plutus Optimization Example

Installation

• Checkout submodules private-alonzo-testnet and exunits-calculator by running git submodule update --init
• Download cardano-node binaries by running ./private-testnet/scripts/install.sh
• Install exunits-calculator dependencies by running cd exunits-calculator && npm install && npm install -g ts-node

Execution

• You need to run private testnet first by ./private-testnet/scripts/reset.sh
• There are 2 bash scripts run.sh and run_optimize.sh, each script will trigger a mock transaction to plutus script defined on OnChain.hs file. The transaction data will be stored on tx.raw and tx_optimized.raw which will be analyzed later
• Basic steps:
  • Run the private testnet node
  • Run the run.sh script
  • Stop the node and re-run
  • Run the run_optimized.sh script
  • Open main.ts then append two lines:
    • printExUnitsFromTxBody("../tx.raw");
    • printExUnitsFromTxBody("../tx_optimized.raw");
  • Run cd exunits-calculator && ts-node main.ts, you can see the difference of execution unit and the script size between two implementation methods.
