Block Chunk
This is the lightweight per-shard view of a finalized block: the chunk header, the transactions included for that shard, and the incoming receipts it executed.
Use this when you want shard-local execution without the fuller shard envelope. It is a good fit for chunk-aware tracing, indexing, or analytics that only need the chunk payload. If you also need state changes and the receipts produced by that shard's execution, use Block Shard. For a worked receipt-to-chunk tracing flow, see RPC Examples.
Fetch one chunk — a single shard's transactions and incoming receipts — at a chosen block height.
