Use Cases#

The eth_getBlockByHash method is essential for:

Block verification - Verify block data using its unique hash
Chain reorganization handling - Track blocks during reorgs
Cross-chain bridges - Verify block finality for high-frequency DeFi (PancakeSwap), NFT marketplaces, and GameFi applications
Deterministic queries - Get consistent block data regardless of chain state

Parameters#

Parameter	Type	Required	Description
`blockHash`	`DATA`	Yes	32-byte block hash
`fullTransactions`	`Boolean`	Yes	If `true`, returns full transaction objects; if `false`, returns transaction hashes
