eth_getBlockByHash on HyperEVM
Fetches a full block by its hash. Identical payload to eth_getBlockByNumber but keyed on the 32-byte block hash.
Use it when you already hold a hash (from a log or a parent-hash walk) and need reorg-safe lookup: unlike a block number, a hash pins one specific block even across a reorg.

Blocks on HyperEVM
HyperEVM uses a dual-block architecture: small blocks land roughly every second for ordinary transactions, with larger-capacity "big blocks" interleaved about once a minute for heavier deployments. Block numbers advance across both.
