Creditcoin Mining Node Setup

Prerequisites

Setup Steps

  1. In order to receive mining rewards you will need an account on the Creditcoin network. Each account has an address and a balance associated with it. The account is backed by a keypair. You can use an existing ECDSA keypair (e.g. from pre-Creditcoin 2.0) or you can generate a new keypair. You can use subkey to retrieve the account address from an existing private key (e.g. from pre-Creditcoin 2.0) or to generate a new keypair.

    • Using an existing ECDSA keypair:

      • Your private key should be formatted as hex and start with 0x, for example 0x3351b11eca7b5c78c0f55c681d9a2e8a0630bcc7a95a35a4a87615c916771774

        • Note: if your existing private key starts with 00, remove the leading 00 first.

      • Run docker run -it docker.io/parity/subkey inspect --scheme Ecdsa <private key> which will display the account information fot the keypair. For example:

        Secret Key URI `0x3351b11eca7b5c78c0f55c681d9a2e8a0630bcc7a95a35a4a87615c916771774` is account:
Secret seed:       0x3351b11eca7b5c78c0f55c681d9a2e8a0630bcc7a95a35a4a87615c916771774
Public key (hex):  0x02abf7befd96f80ce3a27772e7903f45a930c54ede2f0b9e052bfb21e90e0a4b40
Account ID:        0xe37a568057962e95990cbba46c68f8d5b0d0d614abc8bc9f4e46af3e7aa8880c
Public key (SS58): KW6p8XTkd6pLhTnwfSfr3hUcVSKTQhJHZxTVD8RrpfUhUTrvn
SS58 Address:      5HCy4x9b5mW28EYheGn14bWidQkhab5VMiNakia7i4VfxTKs

      • Copy the SS58 Address for later use

    • Generate a new keypair

      • Run docker run -it docker.io/parity/subkey:latest generate. This will generate a new keypair and print the account information, for example:

        Secret phrase:       toss frown run relief book lift aunt guard reduce shell genuine alarm
Network ID:        substrate
Secret seed:       0x5ad92bddf82eae47f5c9cc77a749fd175d9d80aadeab6555e3126a087f5eb5f1
Public key (hex):  0x03084078b5d3633f53ceb103199332aaf86e7ebc1b2975e697dd5dc8653692b7b9
Account ID:        0x7bbf1daa8ccb9aedccade233879f299a5485fbd0922d9458b19a5dbfde71da3c
Public key (SS58): KW8u8Y1GgAGWtTfU5o92imPsYVkowfbsKE7hosQHwJ2E7gF9h
SS58 Address:      5ErxX8PgVYVE3WbCkSs9mvioFHVrsc4uXFwkF3G9Pyv4FC2w

      • Store your secret phrase (a 12-word mnemonic) in a secure location. We won’t use this phrase directly, but you’ll need it to access the account or recover your private key.

      • Copy the SS58 Address for later use

  2. Start mining node

    • Make make sure that your port 30333 is accessible by external connections

    • Obtain your public IP address

    • Run (remove comment lines first)

      docker run -p 30333:30333 -v <your local data path>:/data gluwa/creditcoin:2.0.0-beta-5 \
    # running a mining node
    --validator \
    # (optional) REPLACE <nodename> with a name for your node, to make it easier to identify
    --name <nodename> \
    # allow prometheus metrics to be scraped
    --prometheus-external \
    # (optional) opt in to telemetry
    --telemetry-url "wss://telemetry.polkadot.io/submit/ 0" "wss://telemetry.creditcoin.network/submit/ 0" \
    # node to connect to on boot, in order to join the network
    --bootnodes "/dns4/bootnode.creditcoin.network/tcp/30333/p2p/12D3KooWAEgDL126EUFxFfdQKiUhmx3BJPdszQHu9PsYsLCuavhb" "/dns4/bootnode2.creditcoin.network/tcp/30333/p2p/12D3KooWSQye3uN3bZQRRC4oZbpiAZXkP2o5UZh6S8pqyh24bF3k" "/dns4/bootnode3.creditcoin.network/tcp/30333/p2p/12D3KooWFrsEZ2aSfiigAxs6ir2kU6en4BewotyCXPhrJ7T1AzjN" \
    # REPLACE <yourhostname or ip> with the public IP address or host name that your node can be reached at
    --public-addr "/dns4/<yourhostname or ip>/tcp/30333" \
    # we want to connect to the mainnet
    --chain mainnet \
    # REPLACE <SS58Address> with your mining public key/address to receive rewards at
    --mining-key <SS58Address> \
    # the base path to store the node's data
    --base-path /data \
    # the port to use for node-to-node communication
    --port 30333
