Blockchain technology has rapidly expanded in recent years, impacting ICT and cryptocurrencies. It offers complete security for transactions, recording each transaction in a block that serves as a record sheet. Blockchain has changed how we interact with the internet, reducing transaction costs, eliminating middlemen, and increasing immutability and transparency. The community of blockchain technologies is multifaceted, with distinct frameworks meeting different users' needs and use cases. This study presents an in-depth comparison of blockchain frameworks, including Ethereum, Quorum, Corda, Ripple and Hyperledger Fabric to help developers and organizations in selecting the most preferable platform for their unique use cases. The study evaluates the blockchain frameworks on the basis of performance analysis metrics such as consensus techniques, throughput, latency, and transaction per second with Hyperledger Fabric being the most suitable choice for achieving throughput and scalability.

To solve the concerns of malicious node removal and node corruption caused by idle node voting and long election cycles of the Delegated Proof of Stake (DPoS) consensus process, a new solution is proposed. First, we design a time-cost-based incentive mechanism that provides commensurate compensation to all nodes participating in the consensus strive system nodes to participate in voting actively. Second, we present a reward and punishment scheme based on trust value that sets the node status and corresponding trust value for nodes and dynamically adjusts the node status and associated trust value by monitoring node behavior and provides the function Optimization is performed to make it more difficult for bad nodes to get votes, to speed up the removal of wicked nodes, and to resist node bribery attacks. Finally, a list of alternate witness nodes is included to address the issue of system security weakening caused by the vacancy of hostile nodes once their proxies are revoked. The experimental results before and after the mechanism modification are compared to validate the usability and effectiveness of the improvement scheme.

Supply chain finance business as a comprehensive financial solution for small and medium-sized enterprises or small and micro enterprises has been for many years, but in the new era of the information wave, the traditional model of supply chain finance has revealed its irreconcilable drawbacks, and the arrival of block chain technology seems to bring new solutions. Block chain technology has the advantages of immutable information, decentralization, strong traceability and so on. It can break the single vertical transaction upstream and downstream of enterprises, promote the upgrade of network structure, and create a financial industry chain that efficiently delivers value, so as to achieve a win-win situation among all participants based on credible and verifiable trade relations. Based on this, this paper gives an overview of the supply chain finance model and block chain technology, and analyzes the application of block chain technology in supply chain finance.

We discuss the current state of the Canadian real estate market and the impact blockchain technology could have on it. We start with a review of the current popular and scholarly literary landscape relating to blockchain technology and its real estate applications. Special focus is given to the impact the technology could have on transaction costs, transaction times and fraud deterrence in this market. Preliminary recommendations are provided in the form of blockchain based bidding and transaction systems.

Flexibility value of enterprise's logistics capability is one of the key factors which influence the quick response to customers in decentralized supply chain.This article analyzed the characteristics of enterprise's logistics capability in decentralized supply chain,defined the flexibility of enterprise's logistics capability and its value,and analyzed the way of calculating the uncertain investment benefits.Then we constructed the model of flexibility value of enterprise's logistics capability based on multistage stochastic mix integer programming and real option through investment.The surpassing sample technology of Latin super cube and Monte Carlo were put forward to solve this problem.This model solved the problem that anomalous value calculation of logistics capability investment was ignored by traditional finance method.Finally a case explained that this model was effective on calculating flexibility value of enterprise's logistics capability.

The foundations of government audit have close relationship with public governance.This paper,based on the theory of public governance,reconsiders and reconstructs foundations of government audit from four aspects.In the new epoch,we should make the best of incremental function of government performance audit in order to construct efficient government,make the most of assurance function of finance audit for macro adjustments and controls in order to construct limited government,take full advantage of restriction function of economic responsibility audit for power in order to construct decentralized government and strengthen state audit report system and make the best of assurance function of government audit in order to construct a transparent government.

College system is relatively widely adopted management model of decentralization in our country.Based on the analysis of prlblems in the operation of college system,the paper believes it necessary for colleges to be entrusted three powers autonomous financing,autonomous personnel placement and autonomous allocation of college resources so that the advantages of structural reform of college system can be made use of and the college itself will become a relatively independente ducational entity,The paper expounds the connotation and method of college autonomous financing which is the basis of power for college real operation,and makes an analysis of advantages of college autonomous financing.
