<![CDATA[Indonesia's halal industry faces significant challenges in bridging the gap between 30 million products requiring mandatory halal certification and only 9.6–9.8 million products officially registered with BPJPH, compounded by 40% consumer skepticism toward halal claims due to a paper-based certification system vulnerable to forgery. Blockchain-enabled intelligent platforms are essential to enhance transparency and trust through real-time digital verification. To design and test a blockchain-based halal verification platform integrated with QR codes and intelligent information systems, enabling end-to-end tracking from producers to consumers, reducing certification fraud, and improving consumer trust and system efficiency. This study employs a quantitative-explanatory R&D approach to develop a three-tier system (frontend web/mobile, Python/SQL backend, blockchain simulation), tested for performance on 10,000–100,000 halal product datasets. Primary data (Likert-scale trust scores, response time, accuracy) and secondary data (BPJPH statistics) were analyzed using descriptive statistics and scalability simulations. Research Findings: The platform achieved 99.7% verification accuracy, 1.2–2.1 second response times, and a 0.3% error rate. Consumer trust scores improved from 3.1 to 4.3 (+39%), with 92% of users rating the system as "very user-friendly." The system scaled effectively to 100,000 datasets with CPU usage below 40%. Blockchain-enabled intelligent platforms effectively enhance consumer trust, certification transparency, and computational efficiency, supporting Indonesia's target of 100% mandatory halal certification by 2030–2035. This platform is ready for integration with BPJPH's ecosystem for national-scale UMKM and halal industries.]]>
