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


This script removes a validator account from the validator set, and triggers a reconfiguration of the system to remove the validator from the system. This transaction can only be successfully called by the Libra Root account.

Technical Description

This script removes the account at validator_address from the validator set. This transaction emits a LibraConfig::NewEpochEvent event. Once the reconfiguration triggered by this event has been performed, the account at validator_address is no longer considered to be a validator in the network. This transaction will fail if the validator at validator_address is not in the validator set.

sliding_nonceu64The sliding_nonce (see: SlidingNonce) to be used for this transaction.
validator_namevector<u8>ASCII-encoded human name for the validator. Must match the human name in the ValidatorConfig::ValidatorConfig for the validator.
