This study synthesizes current developments concerning the application of blockchain technology to reinforce halal certification integrity and strengthen consumer trust. A systematic literature review (SLR) was carried out following the PRISMA protocol, using Scopus and Web of Science databases covering 2019- 2025. From an initial 108 records, 48 studies met the eligibility criteria and were analyzed thematically. The review reveals four interconnected domains traceability and transparency, governance and regulatory structures, organizational readiness, and technological orchestration which jointly determine blockchain readiness within halal ecosystems. The findings demonstrate that blockchain, particularly when combined with IoT, AI, and smart contracts, facilitates secure verification, improves data integrity, and enhances auditability. A conceptual framework is proposed to illustrate how institutional capacity, technological integration, and regulatory harmonization collectively shape consumer trust
