Struct PoWGrinder 

pub struct PoWGrinder<S: PowStrategy> { /* private fields */ }

Standalone proof-of-work grinder that can work with any byte challenge.

This structure provides a clean separation between the PoW solving logic and the transcript/sponge operations.

Implementations

impl<S: PowStrategy> PoWGrinder<S>

pub fn new(challenge: [u8; 32], bits: f64) -> Self

Creates a new PoW grounder with the given challenge and difficulty.

Arguments

• challenge - A 32-byte challenge array
• bits - The difficulty in bits (logarithm of expected work)

pub fn grind(&mut self) -> Option<PoWSolution>

Attempts to find a nonce that satisfies the proof-of-work requirement.

Returns the minimal nonce that makes the hash fall below the target threshold, or None if no valid nonce is found (extremely unlikely for reasonable difficulty).

pub fn verify(&mut self, nonce: u64) -> bool

Verifies that a given nonce satisfies the proof-of-work requirement.
