📊 bBench Setup & Benchmark Execution

This guide outlines the steps to configure a benchmarking environment using Hardhat and Hyperledger Caliper, based on the bBench project.

---

✅ Requirements

• One contract per file
• The contract name must match the name of the contract defined in the Solidity code

---

⚙️ Installation and Component Structure

📁 Hardhat Component

This component simulates a local Ethereum network where the benchmark will be executed.

1. Download the Hardhat folder from the bBench repository.

   /hardhat

---

📁 Caliper Component

This component runs the tests and generates performance metrics based on the smart contracts.

1. Download the Caliper folder from the bBench repository.

   /caliper

---

📥 Step 1 — Prepare the Input Folder

Copy the contract(s) to be tested into:

/hardhat/contracts

---

⚙️ Step 2 — Generate ABI Code

Compile the contracts with Hardhat to generate ABI files:

cd hardhat
. compile.sh contract_file.sol

---

📁 Step 3 — Set Up the Scenario

1. Edit the function parameters file:

   /caliper/workloadGen/functionParameters.json

2. Run the scenario creation script:

Usage: createParam.sh MaxRound NumberOfWorkers RampUp(min) MeasurementTime(min) RampDown(min) NumberOfTps

cd /caliper/ethereum
. createScenario.sh 10 5 2 10 2 200

---

🚀 Step 4 — Run the Benchmark

With everything set up, run the benchmark tests:

1. Run the bBench!!

Usage: startC.sh ContractName

cd /caliper/ethereum
. startC.sh contract_file

---

📈 Step 5 — Analyze the All Merged Output Files

/caliper/ethereum/output

---

(Optional) 🐘 Step 6 — Insert the CSV Files into PostgreSQL DataBase

Run DDL.sql Create the tables using this file.

Run EDA.sql to visualize and analyze the results.

---

🧪 Final Notes

• Make sure all file paths are correct and required configuration files are present.
