Function diem_transaction_builder::stdlib::encode_create_validator_account_script

pub fn encode_create_validator_account_script(
    sliding_nonce: u64,
    new_account_address: AccountAddress,
    auth_key_prefix: Vec<u8>,
    human_name: Vec<u8>
) -> Script

Summary

Creates a Validator account. This transaction can only be sent by the Diem Root account.

Technical Description

Creates an account with a Validator role at new_account_address, with authentication key auth_key_prefix | new_account_address. It publishes a ValidatorConfig::ValidatorConfig resource with empty config, and operator_account fields. The human_name field of the ValidatorConfig::ValidatorConfig is set to the passed in human_name. This script does not add the validator to the validator set or the system, but only creates the account.
