+     * @param signature The raw bytes of the Ed25519 signature over the concatenated bytes of
+     * [subnetID]+[nodeID]+[blsPublicKey]+[weight]+[balance]+[expiry]. This signature must correspond to the Ed25519
+     * public key that is used for the nodeID. This approach prevents NodeIDs from being unwillingly added to Subnets.
+     * balance is the minimum initial $nAVAX balance that must be attached to the validator serialized as a uint64.
+     * The signature field will be validated by the P-Chain. Implementations may choose to validate that the signature
+     * field is well-formed but it is not required.
