WebJun 21, 2024 · 1. Block Hash Block hash is the main identification parameter of a block. This value is obtained by cryptographic hashing of the header of the block. The hashing operation is performed twice. The header of the block contains metadata of the block and when this data is hashed the result is the block hash, whose size is 32 bytes.
