Deploy Bootnode

Setup bootnode on GCP

Go to https://node.unitcode.org/ and follow instructions for deploying node to GCP up until "Compile UNC codebase".

Build the node if you haven't done it yet.

Configure the validator keys (optional)

There is a set of keys configured by default in the chain, the 12-word seed phrase is the following:

tape between genre critic crouch adjust slot eternal cancel cry witness lucky

This private key is used to derive the set of keys for the initial validators and is the account with root privilege.

Generate the keys

Steps to deploy a chain using a new key:

Generate a new phrase using 'subkey'

./target/release/node-unitchain key generate

The result of this demostration is:

Secret phrase: rose cushion master install sentence want tuition simple goat jungle write help Network ID: substrate Secret seed: 0xe5771303b02b91117ac66f4a18581471f90a0d50763593528b42c86e9dcac5cf Public key (hex): 0x1ccd91edf2ef62e68daf6e9eda947c6c980986330dcc2e7da0bebaaf629f494f Account ID: 0x1ccd91edf2ef62e68daf6e9eda947c6c980986330dcc2e7da0bebaaf629f494f Public key (SS58): 5CiUGKg8FBucJ6fyeTrSSmEL9BAqFJzLGqyWZwyHygamHjXs SS58 Address: 5CiUGKg8FBucJ6fyeTrSSmEL9BAqFJzLGqyWZwyHygamHjXs

Replace the root key in 'node/src/chain_spec.rs' on the function 'staging_network_config_genesis'

The lines should look like:

.
.
.
// generated with secret: subkey inspect "$secret"
    let root_key: AccountId = hex![
        // 5CiUGKg8FBucJ6fyeTrSSmEL9BAqFJzLGqyWZwyHygamHjXs
        "1ccd91edf2ef62e68daf6e9eda947c6c980986330dcc2e7da0bebaaf629f494f"
    ].into();
.
.
.

Generate the set of keys for the validators:

Replace the 'VALIDATOR_BASE_KEY' variable located at 'scripts/session_keys/keys.sh' with secret seed generated in (1).
Run the following command, you need to specify the number of validators:

./scripts/prepate-test-net.sh 3

You will see the following result in the console:

IMPORTANT Delete the 'data' folder if any and build the node before moving to next step.

Start the node

Run the following command to start the set of nodes:

nohup ./scripts/start_multi_node.sh &

The previous command will run the three nodes in the background and insert the keys into the nodes.

At this point, the blocks should begin to be produced and finalized.

A folder called 'data' will be created with the database, keystore, and log for the nodes.
