Blocks, extrinsics and events

A block is a batch of state transitions. An extrinsic is a call submitted to the chain — a transfer, a registration, a weight update. Events are what the runtime emitted while executing them, which is where the outcome of a call actually shows up. Most questions about what happened are event questions.

Published share is not paid share

A subnet's emission share is what it would receive; the gate decides what it does receive. Between the two sit a weighting and the gate itself, and a subnet reaches zero by three separate routes: never eligible to emit, eligible with emission switched off, or eligible and enabled but weighted to nothing before the gate ever sees it. Ranking by the published figure puts a subnet that is paid nothing above one that is paid, which is the gate stated backwards.

Depth and freshness

Recent chain state is served hot; deep history is served from the lakehouse and can answer more slowly for a wide range. Where a query reaches past the warm window the response says so explicitly rather than returning a truncated result that looks complete.
