Hash Rate

Number of hash computations per second performed by miners; proxy for network security in PoW.

Hash Function

Algorithm mapping arbitrary‑length input to fixed‑length output with properties like preimage resistance.

Hash

Fixed‑length digest computed from data by a hash function; used for addressing and integrity.

Hard Fork

Incompatible protocol upgrade that requires nodes to update; may produce a split chain.

Hard Cap

Maximum token supply or fundraise amount that will ever be issued or raised.

Grounding

Linking model outputs to verifiable data or tools to reduce hallucinations.

Ground Truth

Authoritative labels or facts used for training and evaluating models.

Greedy Decoding

Strategy that picks the highest‑probability token at each step; fast but can be myopic.

Gradient Descent

Optimization method that iteratively updates parameters in the direction of negative gradient.
