Struct sui_types::messages_consensus::AuthorityCapabilities

pub struct AuthorityCapabilities {
    pub authority: AuthorityName,

    pub supported_protocol_versions: SupportedProtocolVersions,
    pub available_system_packages: Vec<ObjectRef>,
}
Expand description

Used to advertise capabilities of each authority via narwhal. This allows validators to negotiate the creation of the ChangeEpoch transaction.

Fields§

§authority: AuthorityName

Originating authority - must match narwhal transaction source.

§generation: u64

Generation number set by sending authority. Used to determine which of multiple AuthorityCapabilities messages from the same authority is the most recent.

(Currently, we just set this to the current time in milliseconds since the epoch, but this should not be interpreted as a timestamp.)

§supported_protocol_versions: SupportedProtocolVersions

ProtocolVersions that the authority supports.

§available_system_packages: Vec<ObjectRef>

The ObjectRefs of all versions of system packages that the validator possesses. Used to determine whether to do a framework/movestdlib upgrade.
