Decentralization

Distribution of control across many parties to reduce single points of failure and capture.

DCA Layered Orders

Automated strategy that splits orders into timed slices, often implemented via keeper networks or smart vaults.

DCT (Dispute Game)

Interactive verification process used by optimistic rollups to prove fraud via bisection and on‑chain resolution.

Dataset Shift

When the distribution of real‑world data differs from the training distribution, causing degraded model performance.

DAS Proof

Evidence produced by data availability sampling that a block’s data is accessible with high probability.

Dark Pool

Trading venue where orders are hidden until execution to reduce front‑running; hard to decentralize safely.
