Generating a libp2p Key Pair

libp2p keypairs are gossip network identities. To ensure connectivity across the network, all seed nodes must start with a stable libp2p keypair so that other nodes can reliably connect.

info

libp2p keys are different from wallet keys. To generate a wallet key pair, see Generating a Key Pair.

Generate the keypair

Use the mina libp2p generate-keypair command:

mina libp2p generate-keypair --privkey-path ~/keys/my-libp2p

caution

Do not store libp2p keys in the same file as your wallet keys.

Use the keypair

Pass the generated key to the Mina daemon with the --libp2p-keypair flag:

mina daemon ... --libp2p-keypair ~/keys/my-libp2p ...
