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.

$ ./build/bin/istanbul extra

setup subcommand

Click here to expand

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 file has the IP and port values defined using the flags --nodeIp, --nodePortBase, and --nodePortIncrement. If these flags are not provided then the IP 0.0.0.0 and port 30303 will be used; in which case, the static-nodes.json will require manual changes to match your environment.

setup examples

$ ./build/bin/istanbul setup --num 4 --nodes --verbose --nodeIp 127.0.0.1 --nodePortBase 21000 --nodePortIncrement 1
