Configure

::::: tip

Connect to the right network

:::: tabs

::: tab mainnet

In order to connect to the mainnet be sure to use one of the following configurations:

GNY_P2P_PEERS=/ip4/78.141.235.22/tcp/4097/p2p/QmdEmHir6AxNzHrhWBJ3PfUddRBabmmEGmdSaCenrKMCUh

:::

::: tab testnet

In order to connect to the testnet be sure to use one of the following configurations:

GNY_P2P_PEERS=/ip4/192.248.155.206/tcp/4097/p2p/QmUTkMvTdFsgNdtYMcN6U7VHBMzcVbg2oC3xYCagCJbRNs

:::::

Start Forging

::: warning
Do not reuse your delegate secret on different GNY Blockchain networks (localnet, testnet, mainnet). Otherwise you will make yourself vulnerable to replay attacks.
:::

::: tip
In order to start forging you need to first register as delegate. Be sure to checkout our Guides on how to register as delegate and how to create a random secret.
:::




In order to start forging please pass a secret or multiple secrets (comma separated) to the GNY Blockchain. This option is optional.

Change CLI arguments:

- npm run start
+ npm run start -- --secret="chief next globe deny try danger trust wet spoil away eight task"

Change your docker-compose.yml:

services:
  # db1 service omitted
  node1:
    # other keys omitted
    environment:
+     - GNY_SECRET=chief next globe deny try danger trust wet spoil away eight task

Configure Public IP

::: warning
The publicIp option is mandatory on the testnet and on the mainnet. If you don’t set it then the node will automatically use its privateIp which which will make the p2p communication with other nodes not work.
::::

Pass public ip as argument:

- npm run start
+ npm run start -- --publicIP="20.188.42.0"

Pass public ip as environment variable:

services:
  # db1 service omitted
  node1:
    # other keys omitted
    environment:
+     - GNY_PUBLIC_IP=20.188.42.0

::: tip
After that the nodes own public ip configuration should be checked with the HTTP API endpoint /api/peers/info. This endpoint displays information about the own node!
:::

multiaddrs_publicIp_api_peers_info

Configure Network

The option network sets which network the node should connect to. This option is mandatory.

The network can be passed to the GNY node:

  • as argument --network=mainnet
  • as environment variable GNY_NETWORK=mainnet

:::: tabs

::: tab mainnet

services:
  # db1 service omitted
  node1:
    # other keys omitted
    environment:
+     - GNY_NETWORK=mainnet

:::

::: tab testnet

services:
  # db1 service omitted
  node1:
    # other keys omitted
    environment:
+     - GNY_NETWORK=testnet

:::

::: tab localnet

services:
  # db1 service omitted
  node1:
    # other keys omitted
    environment:
+     - GNY_NETWORK=localnet

:::

Configure P2P Secret




The p2p secret keeps the connection between peers secure. This is option is mandatory.

The p2p secret can be passed to the GNY node:

  • as argument: --privateP2PKey="CAASqQkwggSlAgEA..."
  • as environment variable: GNY_P2P_SECRET="CAASqQkwggSlAgEA..."

Pass p2p secret as argument:

- npm run start
+ npm run start -- --privateP2PKey="CAASqQkwggSlAgEA..."

Pass p2p secret as environment variable:

services:
  # db1 service omitted
  node1:
    # other keys omitted
    environment:
+     - GNY_P2P_SECRET="CAASqQkwggSlAgEA..."

Configure P2P Peers

The p2p peers option says to which peer(s) (comma separated) we should connect in the network. This option is optional

The p2p peers option can be passed to the GNY node:

  • as argument: --peers="/ip4/192.248.155.206/tcp/4097/p2p/QmUTkMvTdFsgNdtYMcN6U7VHBMzcVbg2oC3xYCagCJbRNs"
  • as environment variable: GNY_P2P_PEERS=/ip4/192.248.155.206/tcp/4097/p2p/QmUTkMvTdFsgNdtYMcN6U7VHBMzcVbg2oC3xYCagCJbRNs

:::: tabs

::: tab mainnet

Pass p2p peers as argument:

- npm run start
+ npm run start -- --peers="/ip4/78.141.235.22/tcp/4097/p2p/QmdEmHir6AxNzHrhWBJ3PfUddRBabmmEGmdSaCenrKMCUh"

Pass p2p peers as environment variable:

services:
  # db1 service omitted
  node1:
    # other keys omitted
    environment:
+     - GNY_P2P_PEERS=/ip4/78.141.235.22/tcp/4097/p2p/QmdEmHir6AxNzHrhWBJ3PfUddRBabmmEGmdSaCenrKMCUh

:::

Pass p2p peers as environment variable:

services:
  # db1 service omitted
  node1:
    # other keys omitted
    environment:
+     - GNY_P2P_PEERS=/ip4/192.248.155.206/tcp/4097/p2p/QmUTkMvTdFsgNdtYMcN6U7VHBMzcVbg2oC3xYCagCJbRNs
