What's new
This version adds support for the pre-latest block concept — a block that has been finalized by consensus but whose commitments are not yet calculated. It acts as a preview of the next block, allowing faster access to the chain state to build the pre_confirmed state.
When the latest finalized block is N, the pre_confirmed block can now be built either:
- directly on top of
N(i.e.,pre_confirmed = N + 1), or - on top of a PreLatest block at
N + 1(i.e.,pre_confirmed = N + 2), if available.
Background
Previously, the pre_confirmed block was always fetched for latest + 1, requiring us to wait for commitments before proceeding.
Impact
This change allows us to fetch the pre_confirmed block earlier by removing the wait for commitments, resulting in access to a more recent state sooner and reducing transaction confirmation latency.
