Fork from https://github.com/drandreaskrueger/chainhammer to work with Hyperledger Besu.

Requirements

• Python >= 3.6

Install dependencies using virtualenv

sudo pip3 install virtualenv
virtualenv -p python3 venv
source venv/bin/activate
pip3 install -r requirements.txt

Configuration

Create a .env with the following environment variables:

• Set the MNEMONIC; used to initiate accounts and sign transactions
• Set the RPC_NODE_SEND; node used to flood the network with transactions
• Set the RPC_NODE_WATCH; node used to observe and analyze each block TPS (transactions per second)

Quickstart

0. Node up and running?

source venv/bin/activate
hammer/is_up.py

1. Deploy Storage contract:

hammer/deploy.py

2. Start TPS measuring

NOTE: Start a new terminal session.

source venv/bin/activate
hammer/measure_tps.py

3. Flood the network with transactions

Use the first 3 accounts to broadcast 100 transactions.

NOTE: The first account (index 0) needs to have funds. It will then send 5 ETH to each new account.

source venv/bin/activate
hammer/send.py 100 accounts 3
