The UZ agricultural ecological chain mainly applies blockchain technology to agriculture, and one of the main application scenarios is authentication traceability. By utilizing the immutable and timestamp characteristics of blockchain technology, it has been applied in the circulation of agricultural products and other items. Currently, the application of this technology in the agricultural field is relatively scarce. The cloud based green pomelo platform created by the UZ agricultural ecological chain assists scientific production through big data systems, and smart contracts are applied to agriculture to promote the development of agricultural industrialization.The token points UZ has the following functions:The first is the proof of digital rights, where UZ is a certificate of rights that exists in digital form, representing a right, an inherent and inherent value.The second is encryption, where the authenticity, tamper resistance, and privacy protection capabilities of UZ are guaranteed by cryptography. Every UZ token is a right protected by cryptography. This protection is more robust and reliable than any protection provided by law, authority, etc.The third is on chain circulation, where UZ flows on the blockchain and can be verified anytime, anywhere....
