| 520 | 3 | |a Public procurement remains a major vector for value leakage in East Africa through bid-rigging, opaque variations, unverifiable milestones, and off-ledger payments. This paper evaluates whether blockchain-enabled transparency deployed in a minimal, technology-agnostic form can measurably reduce such corruption. Rather than proposing a new platform, we benchmark documented deployments of blockchain for public integrity (e.g., procurement logging and tamper-evident audit trails) to extract a minimal control set: proof-before-payment smart contract milestones, independent validation of two-key approvals by an external validator in addition to the implementing agency, and public payment portals. We then examine factual Kenyan case studies and estimate the opportunity cost of corruption by benchmarking foregone productivity, missed jobs, and Gross Domestic Product (GDP) against outcomes observed in higher-performing systems. The methodology combines case timelines with a counterfactual benefits model and sensitivity analysis. We report (i) sector-specific loss estimates, (ii) the failure points that the extracted controls would have blocked or exposed, and (iii) a six-month pilot blueprint with evaluation metrics (competition, price variance, evidence-linked payments, time-to-pay, complaints). The contribution is a policy-ready, auditable workflow that translates proven blockchain practices into actionable procurement controls for East African governments, demonstrating quantitatively how replacing opaque paper trails with verifiable proof trails can recover public value. Keywords: blockchain; public procurement; anti-corruption; smart contracts; independent validation; transparency portal; open contracting; stadium infrastructure; Kenya; East Africa.
