This requirement ensures no signature malleability. Each transaction must have at least one signature for [fee account](terminology#fee-account).
Thus, the first signature in transaction can be treated as [transacton id](terminology.md#transaction-id)
## skipped slot
A past [slot](terminology.md#slot) that did not produce a [block](terminology.md#block), because the leader was offline or the [fork](terminology.md#fork) containing the slot was abandoned for a better alternative by cluster consensus. A skipped slot will not appear as an ancestor for blocks at subsequent slots, nor increment the [block height](terminology#block-height), nor expire the oldest `recent_blockhash`.
Whether a slot has been skipped can only be determined when it becomes older than the latest [rooted](terminology.md#root) (thus not-skipped) slot.
## slot
The period of time for which a [leader](terminology.md#leader) ingests transactions and produces a [block](terminology.md#block).
The period of time for which each [leader](terminology.md#leader) ingests transactions and produces a [block](terminology.md#block).
Collectively, slots create a logical clock. Slots are ordered sequentially and non-overlapping, comprising roughly equal real-world time as per [PoH](terminology.md#proof-of-history).
