What happens in a slot?

The consensus schedule gives an opportunity for a block proposal.

LET’S PICTURE IT

A timetable can reserve a turn for a speaker even if that speaker misses the turn.

SEE IT FOR YOURSELF

Receive, check and share across independent nodesStep 1 / 4

A node receives a proposed transaction or block-related message. Receipt is not the same as accepting its claims.

A scheduled interval

Ethereum proof of stake organizes time into slots under protocol constants. A proposer is assigned for the relevant opportunity. A slot is a scheduling unit, not a promise that a usable block will appear.

A proposal contains several kinds of data

A block includes consensus information and an execution payload under the protocol’s format. The execution side still needs to check the payload’s transactions and state effects.

An empty opportunity can happen

Missed proposals or network problems can leave a slot without a block in the accepted view. Blocks and slots therefore should not be treated as interchangeable counts in every situation.

Voting relates to the chain

Validators make attestations under their duties. These support fork choice and checkpoint agreement rather than a separate popularity vote for every payment. Read epochs and finality next for the wider timing structure.

QUICK CHECK · NO PRESSURE

Does each scheduled slot guarantee an accepted block?
