New Framework

An emergent use of the blockchain technology is to enable the transfer of digital assets between two parties. An extension to this is the Smart Property in which physical assets could be transferred too. Another extension is the exchange of services of all kinds in form of digitally executed contracts. In this paper, the problems with existing attempts to implement an all-inclusive smart contract platform were identified and a new framework proposed. In this framework, the technical and legal terms of any contract could be executed digitally if prepared with appropriate legal prose and required parameters for each of the terms of the contract. The cores of the framework are the technical, business and legal models, which are connected to each other. The technical model adapts block chain technology while ensuring granularity in implementing the terms of the contract as presented by the legal model using legal prose and necessary parameters. Using the proposed framework, some questions that have persisted with current implementation of Smart contracts that involves the blockchain were answered. The framework improves the efficiency and practicability of using smart contract for physical assets and non-financial services with emphasis. The contribution is mainly on ensuring an adoptable and practicable smart contract platform.

Initial Uncertainty

Blockchain technology as an infrastructure allows an innovational platform for a new transparent and decentralized transaction mechanism for different type of industries and businesses. Different attributes of blockchain technology increase trust through traceability and transparency ability of goods, data and financial resources within any transaction. Regardless of initial uncertainty about this technology, government and many major enterprises and firms have recently examined the adoption and improvement of this technology in several areas of applications, from social, legal and finance industries to manufacturing, design and supply-chain networks. An interesting research problem in this new era is that of determining provenance. At present, goods which are produced and transported using complicated medium supply chains, in this type of supply chain it is impossible to evaluate the provenance of physical goods. We have an interest in the blockchain as there are numerous favored use cases of blockchain especially for provenance tracking. In this paper we review the basics features of the blockchain along with its type like permission less and permissioned blockchain. Then discussed the need of provenance of assets in supplychain as it increase the trust of the customer and proposed a process and architecture for providing the data provenance in supply chain with blockchain using smart contract.

In the field of modern bidding, electronic bidding leads a new trend of development, convenience and efficiency and other significant advantages effectively promote the reform and innovation of China’s bidding field. Nowadays, most systems require a strong and trusted third party to guarantee the integrity and security of the system. However, with the development of blockchain technology and the rise of privacy protection, researchers has begun to emphasize the core concept of decentralization. This paper introduces a decentralized electronic bidding system based on blockchain and smart contract. The system uses blockchain to replace the traditional database and uses chaincode to process business logic. In data interaction, encryption techniques such as zero-knowledge proof based on graph isomorphism are used to improve privacy protection, which improves the anonymity of participants, the privacy of data transmission, and the traceability and verifiable of data. Compared with other electronic bidding systems, this system is more secure and efficient, and has the nature of anonymous operation, which fully protects the privacy information in the bidding process.
