Blockchain-based Traceability for Teak Identity: A Transformational Approach

The Southern regions of India, Myanmar, Thailand, Laos, and Indonesia are where teak originated. Teak is a high-value wood that used to be an export good for Thailand, bringing in a lot of money. Thailand produced approximately 71,954.53 m3 of teak plantation timber and exported wood products worth 1.1 billion baht overseas in 2018, according to the Forest Industry Organization (FIO). Due to its high demand, there is also a chance that smuggled wood from within the country or wood that has been illegally obtained abroad will enter the supply chain. Encroachment and illegal logging are still major problems in Thailand. Blockchain technology has become extremely popular due to its distinctive immutability and traceability properties, which have the opportunity to overcome a variety of issues. In order to get rid of illegal teak timber and achieve traceable, transparent, and reliable teak data that is moved through the teak supply chain, we present a decentralized application (DApp) based on the Ethereum blockchain that implements a traceability system for teak identity. According to the findings of the experiment, our DApp achieves a good trade-off between the system’s gas cost of 116K (2.53 USD) to store data in the Ethereum blockchain and provide high security, transparency, privacy, resilience, and robustness. We observed that the newly proposed blockchain-based system can reduce illegal logging, the usage of paper-based documentation, and the time needed to validate the documentation in teak supply chain controls when we compared it to the traditional process used in the supply chain.
