Function diem_transaction_builder::stdlib::encode_remove_validator_and_reconfigure_script

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

Summary

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 Diem Root account.

Technical Description

This script removes the account at validator_address from the validator set. This transaction emits a DiemConfig::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.
