UniversalHash

Struct UniversalHash 

Source
pub struct UniversalHash { /* private fields */ }
Expand description

UniversalHash v4 hasher

This struct maintains the scratchpads and chain states needed for hashing. It can be reused for multiple hashes to avoid repeated allocations.

Implementations§

Source§

impl UniversalHash

Source

pub fn new() -> Self

Create a new UniversalHash instance

Allocates 2MB of memory for the scratchpads.

Source

pub fn hash(&mut self, input: &[u8]) -> [u8; 32]

Compute the UniversalHash of input data

The input should be formatted as: epoch_seed || miner_address || timestamp || nonce where nonce is the last 8 bytes.

Returns a 32-byte hash.
