##### Abstract

We describe Ginger, a built system for unconditional, general-purpose, and nearly practical verification of outsourced computation. Ginger is based on Pepper, which uses the PCP theorem and cryptographic techniques to implement an \emph{efficient argument} system (a kind of interactive protocol). Ginger slashes the query size and costs via theoretical refinements that are of independent interest; broadens the computational model to include (primitive) floating-point fractions, inequality comparisons, logical operations, and conditional control flow; and includes a parallel GPU-based implementation that dramatically reduces latency.

Note: This paper is an extended version of a previous publication. This version includes four Appendices (B--E) that were elided from the published version, for space, and eliminates an incorrect theoretical claim in the published paper.
