extra helps generate RLP-encoded extra data in ExtraData field of the genesis block. Extra data is composed of signer vanity and IstanbulExtra. IstanbulExtra is defined as follows:
type IstanbulExtra struct {
Validators []common.Address // Validator addresses
Seal []byte // Proposer seal 65 bytes
CommittedSeal [][]byte // Committed seal, 65 * len(Validators) bytes
}Note: Seal and CommittedSeal are not considered in genesis block.

When --nodes --verbose flags are given, a static-nodes.json template as well as the validators' node keys, public keys, and addresses are generated. When --docker-compose is given, a docker-compose.yml for the validators is generated. When --save flag is given, all generated configs will be saved. Use Quorum when --quorum flag is given.
Note: the generated static-nodes.json template are set with IP 0.0.0.0, please make according change to match your environment.
