# Aptos Operational Tool The `aptos-operational-tool` provides a tool for operators to perform maintenance functions on the blockchain post-genesis. The functionality of the tool is dictated by the organization of nodes within the system: * Validator owners (OW) that have accounts on the blockchain. These accounts contain a validator configuration and specify a validator operator. * Validator operators (OP) that have accounts on the blockchain. These accounts have the ability to update validator configuration. ### Important Notes * A namespace in Vault is represented as a subdirectory for secrets and a prefix followed by `__` for transit, e.g., `namespace__`. * A namespace in GitHub is represented by a subdirectory * The GitHub repository and repository owner translate into the following url: `https://github.org/REPOSITORY_OWNER/REPOSITORY` * The owner-address is intentionally set as all 0s as it is unused at this point in time.
