Abstract

The oil and gas (O&G) sector relies on a robust chain of custody mechanisms to ensure the transparency, integrity, and traceability of materials and environmental evidence. Traditional custody systems often suffer from inefficiencies, data fragmentation, and vulnerabilities to unauthorized alterations. This paper presents Cust´ odiaBR, a blockchain-based solution designed to enhance the registration and monitoring of oily waste and oiled fauna samples collected during Petrobras’s Beach Monitoring Projects (Projetos de Monitoramento de Praias - PMPs). Cust´ odiaBR integrates real-time data from a centralized monitoring system and leverages the Brazilian Blockchain Network (RBB) to provide a transparent, immutable, and auditable custody record. The proposed system employs a hybrid on-chain/off-chain architecture, composed of five major components, ensuring data integrity while preserving confidentiality through cryptographic hash verification. Through a comparative analysis with existing blockchain-based forensic solutions, this study highlights the advantages of public-permissioned blockchain in industrial applications, demonstrating how Cust´ odiaBR can serve as a model for digital chain of custody systems.
