SalineLakeChain, a blockchain traceability project for the salt lake industry, referred to as SLC, was initiated by the Hong Kong JiuSheng "Salt Lake Chain" project foundation. The foundation team hopes that the physical product traceability system based on blockchain technology can effectively solve the problem of rare minerals in salt lakes Practical issues such as product traceability, authentication, transaction, and circulation. Through the construction of a distributed network, the design and development of software and hardware products, and the development and trading of salt lake product information chain technology, the "salt lake chain" ecosystem is gradually formed. Through the transparent management of rare mineral identification and transaction information, the The participation threshold has been greatly reduced, which will surely improve industry efficiency, expand the scale of market transactions, and promote the efficient and coordinated development of the salt lake mining industry.
