Blockchain-based trusted traceability and sustainability certification of leather products

Area of Science:

• Supply Chain Management
• Information Systems
• Environmental Science

Background:

• The leather supply chain is complex, often suffering from a lack of transparency, data inaccuracies, and poor provenance.
• Growing environmental consciousness and ethical concerns drive demand for sustainable leather production practices.

Purpose of the Study:

• To propose and validate a blockchain-based system for ensuring trusted traceability and sustainability in the leather supply chain.
• To leverage Ethereum smart contracts for secure and transparent tracking of leather products throughout their lifecycle.

Main Methods:

• Development and implementation of a blockchain-based system utilizing Ethereum smart contracts.
• Integration of a proof-of-sustainability mechanism for monitoring and auditing by certification agencies.
• Validation of system architecture, algorithms, and smart contract security and cost-effectiveness.

Main Results:

• A secure and transparent system for tracing leather materials from origin to consumer.
• A verifiable method for certification agencies to audit and approve sustainable practices.
• Demonstrated robustness and efficiency of the blockchain solution.

Conclusions:

• Blockchain technology offers a robust solution to address complexity and transparency issues in the leather supply chain.
• The proposed system enhances trust, security, and accountability in sustainable leather production.
• Publicly available smart contracts facilitate further development and adoption.
