Manage private keys
The Credit Smart Chain has two types of private keys that it directly manages:
- Private key used for the consensus mechanism
- Private key used for networking by libp2p
Currently, the Credit Smart Chain doesn't offer support for direct account management.
The private keys are stored in simple Base64 format, so they can be human-readable and portable.
# Example private key
As the curve is non-standard, it cannot be encoded and stored in any standardized PEM format. Importing keys that don't conform to this key type is not supported.
The private key file mentioned as the consensus private key is also referred to as the validator private key. This private key is used when the node is acting as a validator in the network and needs to sign new data.
The private key file mentioned for networking is used by libp2p to generate the corresponding PeerID, and allow the node to participate in the network.
As the key files are stored in simple Base64 on disk, they can be easily backed up or imported.
CHANGING THE KEY FILES
Any kind of change made to the key files on an already set up / running network can lead to serious network/consensus disruption, since the consensus and peer discovery mechanisms store the data derived from these keys in node-specific storage, and rely on this data to initiate connections and perform consensus logic
