AuraExt¶

Storage functions¶

Authorities¶

Serves as cache for the authorities.

The authorities in AuRa are overwritten in on_initialize when we switch to a new session, but we require the old authorities to verify the seal when validating a PoV. This will always be updated to the latest AuRa authorities in on_finalize.

Python¶

result = substrate.query(
    'AuraExt', 'Authorities', []
)

Return value¶

['[u8; 32]']

SlotInfo¶

Current slot paired with a number of authored blocks.

Updated on each block initialization.

Python¶

result = substrate.query(
    'AuraExt', 'SlotInfo', []
)

Return value¶

('u64', 'u32')
