Config genesis data and prefunded accounts

• Blockchain config seed_data/blockchain_config.json
• Accounts: 10,000 accounts with private keys generated in seed_data/accounts.json. They can be regenerated with different numbers by using the generate-accounts.py script
• Extra code allocation for smart contracts: Some special account such as precompiled smart contracts that need to be included in genesis, the seed_data/extra_allocation.json shows how to do it. In normal settings for experiments, you dont need to modify the accounts or precompiled smart contracts. You only need to change the blockchain config for block_time and gas_limit etc.

Install required packages

• git clone https://github.com/minhhn2910/ethereum-poa-testnet.git
• cd ethereum-poa-testnet
• pip install -r requirements.txt

Run the blockchain nodes

python poa-deploy.py start [workers param]

How to supply workers param:

Start from a node and counting up with a number of nodes:

python poa-deploy.py start --start-worker 30 --num-workers 8

This will deploy 8 nodes starting from worker-030, worker-031, ...., worker-037

Specify your own list of ip or hostnames:

Create a host file similar to seed_data/host_list.txt, each line is one ip or host that you can ssh into.

Then run with this command:

python poa-deploy.py stop --host-file seed_data/host_list.txt

Check if it runs sucessfully :

• docker services ls`` Check if the nodes are up and running with port 8503, 8504`, ... opens.

Stop blockchain nodes

python poa-deploy.py stop [workers param]

Clean the environment (clean docker swarm)

Optional, you dont need to do it because the script will automatically do it every time the start command is triggered. python poa-deploy.py remove_swarm [workers param]
