eth_getBlockByHash on BNB Chain
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 BNB Chain
BNB Chain runs sub-second blocks since the 2025 Maxwell upgrade (~0.75 s), roughly 16× Ethereum's cadence. Block ranges accumulate extremely fast — "a day" is over 100,000 blocks.
