NBC is an agricultural ecological chain developed by Ethereum, with a total issuance of 68 million pieces, which will never be issued to create a global ecological farming. The blockchain of the agricultural ecological chain builds a distributed structural system according to the open source and decentralized protocol determined by the system, so that the information of value exchange is sent to the whole network through distributed transmission, and the information is determined through distributed bookkeeping. The data content is time-stamped to generate block data, and then sent to each node through distributed transmission to realize distributed storage.
