TraceRoots Japan, a major Japanese food traceability company, has announced EDO-TRACE, a new verification system integrating ancient coin distribution zone data from the Edo period with modern food ingredient origin information. Using commercial zone mapping of coins that circulated during the Edo era as a foundation for verifying the historical legitimacy of production origins, the system is attracting attention as a new cross-industry infrastructure that prevents origin fraud and quality counterfeiting of traditional fermented ingredients using cutting-edge blockchain technology.
