Mina Daemon Requirements

Installation

caution

If you have mina-generate-keypair installed, you will need to first sudo apt remove mina-generate-keypair before installing mina-mainnet=3.0.0-93e0279.
The mina-generate-keypair binary is now installed as part of the mina-mainnet package.

IP and Port configuration

IP:

By default, the Mina Daemon will attempt to retrieve its public IP address from the system. If you are running the node behind a NAT or firewall, you can set the --external-ip flag to specify the public IP address.

Port:

Nodes must expose a port publicly to communicate with other peers. Mina uses by default the port 8302 which is the default libp2p port.

You can use a different port by setting the --external-port flag.

Node Auto-restart

Ensure your nodes are set to restart automatically after a crash. For guidance, refer to the auto-restart instructions

Seed Peer Requirements

Generation of libp2p keypair

To ensure connectivity across the network, it is essential that all seed nodes start with the same libp2p keypair.
This consistency allows other nodes in the network to reliably connect.
Although the same libp2p keys can be reused from before the upgrade, if you need to manually generate new libp2p keys, use the following command:

mina libp2p generate-keypair --privkey-path <path-to-the-key-file>
