Setting up custom networks

Custom Autonity networks

To connect your node to a custom Autonity network, you will need the network’s: - bootnodes, typically given in a static-nodes.json file or specified when running the node with the --bootnodes command-line option. - genesis configuration file, genesis.json.

See Local Autonity Network configuration in the Genesis reference for how to create these files.

Note

Note that the client provides a command-line option for connecting to the Autonity Bakerloo Testnet --bakerloo. The node will not run if you specify both genesis and bootnodes for a custom network and a testnet flag. The client will create a genesis block for the custom network’s genesis configuration and the node’s local store will then have an incompatible genesis with the testnet.

1. Install Autonity in a working directory and create an autonity-chaindata sub-directory as described in Running a node, Install Autonity.

2. Create and copy the bootnode file into the autonity-chaindata sub directory:

cp ./<PATH>/static-nodes.json ./autonity-chaindata/

3. Create and copy the genesis file into the working directory:

cp ./<PATH>/genesis.json ./

4. Run the node as described in Running a node, Run Autonity, specifying your custom network by the options:
   • --genesis: to provide the genesis file.
   • --networkid: to provide the network identifier. This is typically the same value as the chainId file in the genesis configuration file, but may be different.
   An example run command for a local development network on localhost could be:

autonity \
        --datadir ./autonity-chaindata \
        --genesis ./genesis.json \
        --networkid 65110000 \
        --http \
        --http.addr 0.0.0.0 \
        --http.api aut,eth,net,txpool,web3,admin \
        --http.vhosts * \
        --ws \
        --ws.addr 0.0.0.0 \
        --ws.api aut,eth,net,txpool,web3,admin \
        --nat extip:<IP_ADDRESS>
        ;
