[][src]Function transaction_builder::encode_add_validator_and_reconfigure_script

pub fn encode_add_validator_and_reconfigure_script(
    sliding_nonce: u64,
    validator_name: Vec<u8>,
    validator_address: AccountAddress
) -> Script

Summary

Adds a validator account to the validator set, and triggers a reconfiguration of the system to admit the account to the validator set for the system. This transaction can only be successfully called by the Libra Root account.

Technical Description

This script adds the account at validator_address to the validator set. This transaction emits a LibraConfig::NewEpochEvent event and triggers a reconfiguration. Once the reconfiguration triggered by this script's execution has been performed, the account at the validator_address is considered to be a validator in the network.

This transaction script will fail if the validator_address address is already in the validator set or does not have a ValidatorConfig::ValidatorConfig resource already published under it.
