Prerequisites

Geth
Parity

Geth (home) setup

In one terminal, initialize the geth chain using this genesis.json

{
    "config": {
        "chainId": 15,
        "homesteadBlock": 0,
        "eip155Block": 0,
        "eip158Block": 0,
        "eip160Block": 0,
        "byzantiumBlock": 0
    },
    "difficulty": "100000",
    "gasLimit": "0x1000000000",
    "alloc": {
        "0xaaB52d66283F7A1D5978bcFcB55721ACB467384b": { "balance": "1000000000000000000000" },
        "0xbb140FbA6242a1c3887A7823F7750a73101383e3": { "balance": "1000000000000000000000" }
    }
}

and run this command:

geth --datadir ./data init genesis.json

Then start the node:

geth --datadir ./data --networkid 15 --rpc --rpcapi eth,web3,net

After doing this, you can enable the mining mode by doing:

geth attach --datadir ./data --exec "miner.setEtherbase('0xaaB52d66283F7A1D5978bcFcB55721ACB467384b'); miner.start(1)"

And you can disable it by doing:

geth attach --datadir ./data --exec "miner.stop()"

Parity (foreign) setup

Start a parity node using the docker image in the e2e/parity directory. Assuming that this image has been built and that the image name is my-parity, run:

docker run -p 8546:8545 my-parity

Deploy contracts and start the bridge

Set the geth node in mining mode. Set http://localhost:8545 as the home RPC URL, http://localhost:8546 as the foreign RPC URL and 0xaaB52d66283F7A1D5978bcFcB55721ACB467384b as the deployer and validator. Deploy the contracts.

To start the bridge, you can do npm run dev, or you can start all the scripts separately.

Generate a block with several transactions

Stop the mining in the node. Then, generate 1000 transactions by doing node scripts/sendUserTxToHome.js 1000. After checking that the node received all the transactions, start the mining again.

This will generate a block with 1000 transactions that the bridge will process.

Generate statistics

After doing all of this, run node scripts/compute-stats.js. This will print some statistics about the processed transactions.
