A Method Of Non-financial Asset Digitization Based On Smart Contract

As blockchain applications extend from financial payment to wider areas,different types of digital assets in blockchain transaction system are becoming richer.The digital assets are mainly divided into financial assets and non-financial assets.The blockchain financial assets generated by the miners according to the consensus,and the correctness is based on the proof of work or proof of stack.When non-financial assets are generated,the members of the blockchain are required to enter the digitized results as the content of digital assets.However,this method would cause false or incorrect input when blockchain applications only trust one single digitized result.Besides,the absence of digital quality control before the generating puts the non-financial assets at the blockchain facing the risk of incredibility.This thesis proposes a new method of non-financial assets digitizing for blockchain applications.We firstly introduce the principle of blockchain technology and the concept of smart contract,and expound that smart contract can execute and store the execution result automatically.Then we analyze existing digital process of non-financial assets,and propose the digital quality evaluation scheme based on semantic description quality evaluation system.At the same time,the reputation value management scheme is designed to motivate blockchain members to submit high-quality digital results.The quality of digital results is optimized by the two optimization schemes.This thesis expounds the process model,platform architecture,smart contract structure and digital event flow,and describes the core algorithm of smart contract in detail.Then we combine digital platform with the digital quality evaluation scheme and the reputation value management scheme,forming the method of non-financial assets decentralization.Finally,the experiment result shows the operation of the smart contract on joint digital platform has the characteristics of decentralization,traceability,low consumption,low delay and low storage cost,which reflects the rationality of the platform design scheme.
