可持续性与数字化:区块链驱动的循环农业研究

区块链技术作为一种颠覆性的数字技术,具有去中心化、开放性、共享性、匿名性、可溯源性等特征,它可以完善农产品的食品安全认证、优化农产品的物流体系结构、革新农业组织的分工合作模式,但目前关于区块链应用于循环农业的研究尚不多见。论文研究搜索并梳理了相关文献知识,根据循环农业以及区块链的技术特征,以北京留民营生态农场为案例,提出了一个基于区块链的数字化循环农业框架,详细阐述了分布式账本、共识算法、代币机制、智能合约等区块链核心技术在框架中的应用。该框架将区块链的“数字化”赋能与循环农业的“可持续性”内涵相融合,能够解决留民营有机蔬菜以次充好、农药残留、生产流程不规范等问题。最后探讨了研究的不足之处并提出未来研究方向,为进一步深入探析区块链在循环农业中的应用研究提供了参考。

Sustainability and Digitalization:Research on Blockchain Driven Circular Agriculture

As a subversive digital technology,blockchain technology has the characteristics of decentralization,openness,sharing,anonymity,and traceability.It can improve agricultural products’food safety certification,optimize the logistics system structure of agricultural products,and innovate the division and cooperation mode of agricultural organizations.At present,there are little researches on the application of blockchain in circular agriculture.Therefore,the research searches and combs the relevant literature according to the technical characteristics of circular agriculture and blockchain,taking Beijing Liuminying Ecological Farm as a case and putting forward a digital circular agricultural framework based on blockchain.It elaborates blockchain core technologies such as distributed ledger,consensus algorithm,token mechanism,and smart contract in the framework.The framework integrates the“digital”empowerment of blockchain with the“sustainability”connotation of circular agriculture,which can solve the problems of adulterated organic vegetables,pesticide residues,and non-standard production processes.Finally,it summarizes the full text,discusses the shortcomings of the research,and puts forward the future research direction,which provides a reference for further in-depth analysis of blockchain application in circular agriculture.
