Abstract:AgricultureofChinaisatypicalagriculturalsystemofsmallproducerandlargemarket,producersaretooscattered.
Agriculturalfoundationremainsweakinthevastruralareas,especiallypoverty-strickenareas.Blockchaintechnologyhasgood
complementarityandapplicabilitywithChina''sagriculturalproductstradingsystem,becauseofitsdistributedstorage,transac‐
tioninformationtransparencyandproductinformationtraceability.However,theagriculturalproducttradingsystemhascharac‐
teristicsofproductdiversity,commercialprocesscomplexity,usergroupwidespread,decentralized,privacyprotectionandso
on.ItisdifficulttoapplythetraditionalblockchaintechnologydirectlytoChina''sagriculturalproductstradinginformationnet‐
work.Inviewoftheaboveproblems,thedesignideaofalliancechainwasadopted,andthetechnologyofmulti-chainagricul‐
turalproducttransactioninformation,whichincludestransactioninformationblockchain,userinformationblockchainandagri‐
culturalproductsinformationblockchainwasputforward.Theproductinformationblockchainprovidedthedetailedinforma‐
tionofagriculturalproductsandguarantethatthetraceabilityandnon-tamperabilityoftheinformation.Theblockchainnodeac‐
