An instructional management system (IMS) regularly manages student data with a centralized database, which may be prone to single points of failure and data tampering. Blockchain can effectively solve the above problems due to its decentralization and immutability. However, the immutability of blockchain restricts the edit of data in some cases (e.g., incorrect score records). In this paper, we propose an advanced decentralized instructional management framework based on redactable blockchain, wherein chain nodes possess the capability to autonomously revise their initiated transactions with regular chameleon hash functions. Concurrently, system users can anonymously report discrepancies or erroneous entries within the blockchain. When such reports are validated and malicious activities are confirmed, the review team can undertake decentralized modifications to rectify the malicious content with our proposed scheme. In addition, we conduct a security analysis of the scheme, evaluating its correctness, collision resistance, and claimability. Finally, experimental results demonstrate that the scheme is practical.

The current blockchain requires higher stability and efficiency. However, leaderBFT consensus and leaderlessBFT consensus have three problems: dominant replica failure, transaction interruption, and high communication overhead and latency. And regardless of leaderBFT consensus or leaderlessBFT consensus, there isn't a very good solution. It's urgent to leverage the advantages of both consensus types to enhance blockchain performance. To solve the problems, this paper proposes the ATBFT consensus protocol. ATBFT elects the dominant replica through reputation value to ensure higher reliability. In addition, ATBFT has an automatic switching mechanism between leaderBFT consensus and leaderlessBFT consensus. The protocol can automatically elect the consensus type according to the current network conditions, effectively utilizing the idle time of the view change to generate more blocks. Furthermore, it can guarantee the execution of the entire consensus process to ensure that the tx2-transactions are uninterrupted. Finally, ATBFT decomposes the blocks: the consensus is performed only through the block header, and the commitment and execution phase of a tx is performed through a linearly propagated block body. According to experimental evaluation, ATBFT has higher usability and practicality.

Blockchain technology has gained traction in Food Supply Chain Management (FSCM), enhancing traceability and transparency. The existing deployments of public or private blockchains face issues in achieving an optimal balance between transparency and decentralization. This work proposes a hybrid blockchain model complemented by an Access Control (AC) mechanism to bolster security, reliability, and usability within FSCM systems. Furthermore, the integration of a recommender system is proposed to utilize data analytics and machine learning for personalizing product offerings and optimizing inventory management, aiming to boost efficiency and consumer satisfaction. The synergy between the hybrid blockchain framework and the recommender system is anticipated to cultivate a more engaged, efficient, and gratified supply chain ecosystem. The model significantly enhances monitoring in 30% of the use cases and supports transparency in a quarter. It also reduces vulnerability cases by 20%. Inventory management is markedly improved, reducing overstock by 25%, confirming the effectiveness of the proposed hybrid blockchain approach.

Today, scientific research is increasingly becoming data-centric and compute-intensive, relying on data and models across distributed sources. However, challenges still exist in the traditional cooperation mode, given the high storage and computing costs, geolocation barriers, and local confidentiality regulations. The Jupyter environment has recently emerged and evolved into a vital virtual research environment for scientific computing, which researchers can use to scale computational analyses up to larger datasets and high-performance computing resources. Nevertheless, existing approaches lack robust support of a decentralized cooperation mode to unlock the full potential of decentralized collaborative scientific research, e.g., seamlessly secure data sharing. In this work, we change the basic structure and legacy norms of current research environments via the seamless integration of Jupyter with Ethereum blockchain capabilities. As such, it creates a Decentralized Virtual Research Environment (D-VRE) from private computational notebooks to a decentralized collaborative research ecosystem. We propose a novel architecture for the D-VRE and prototype some essential D-VRE elements for enabling secure data sharing with decentralized identity, user-centric agreement-making, membership, and research asset management. To validate our method, we conduct an experimental study to test all functionalities of D-VRE smart contracts and their gas consumption. In addition, we deploy the D-VRE prototype on a test net of the Ethereum blockchain for demonstration. The feedback from the studies showcases the current prototype's usability, ease of use, and potential, and suggests further improvements.

Decentralized Finance (DeFi) has revolutionized the financial landscape, with protocols like Uniswap offering innovative automated market-making mechanisms. This article explores the development of a backtesting framework specifically tailored for Concentrated Liquidity Market Makers (CLMMs). The focus is on leveraging the liquidity distribution approximated using a parametric model to estimate the rewards within liquidity pools. The article details the design, implementation, and insights derived from this novel approach to backtesting within the context of Uniswap V3. The developed backtester was successfully utilized to assess reward levels across several pools using historical data from 2023 (pools Uniswap V3 for pairs of altcoins, stablecoins, and USDC/ETH with different fee levels). Moreover, the error in modeling the level of rewards for the period under review for each pool was less than 1%. This demonstrated the effectiveness of the backtester in quantifying liquidity pool rewards and its potential in estimating revenues of Liquidity Provider (LP) as part of the pool rewards, which is the focus of our next research. The backtester serves as a tool to simulate trading strategies and liquidity provision scenarios, providing a quantitative assessment of potential returns for LPs. By incorporating statistical tools to mirror CLMM pool liquidity dynamics, this framework can be further leveraged for strategy enhancement and risk evaluation for LPs operating within decentralized exchanges.

Today, healthcare fraud poses a significant issue, encompassing everything from falsified billing claims and phantom services to the excessive prescription of opioid medications and medical identity theft. These deceptive activities cause substantial financial losses, erode patient trust, compromise healthcare quality, and threaten patient safety. In this paper, we introduce SSI-MedRx, a healthcare system based on blockchain technology and Self-Sovereign Identity (SSI). It is designed to ensure cross-border interoperability, preserve patient privacy, and prevent challenging healthcare frauds, including medical identity theft, phantom billing, kickbacks, and opioid overprescribing. By design, our system empowers patients by granting them complete control over their personal and health data. This shift toward patient-centric data management can potentially reduce the risk of data breaches, enhance care coordination, and improve overall healthcare outcomes.

Decentralized exchange (DEX) platforms such as Uniswap and Balancer operate on several pools where each pool contains two or more cryptocurrencies and constitutes direct trading pairs. The drawbacks here are that liquidity provision requires the contribution of tokens in a specific proportion, and trading may require hopping between pools, hence increasing the transaction fee and gas fee. We propose an automated market maker (AMM) protocol where liquidity providers (LPs) can deposit any amount of tokens into the pool. The protocol preserves the proportion of tokens by total value at the time of deposit and can be seen as a personalized self-balancing portfolio manager. In addition, since the invariant function is dynamic, all exchange pairs are executed from a single composite pool. Nevertheless, the scheme is vulnerable to flash loan attacks and must be used in conjunction with preventive measures.

With the advancement of distributed digital technology, the fashion supply chain management system is undergoing unprecedented transformations. Given the expansion and rapid iteration of the fashion industry, traditional supply chain management models struggle to adapt to the volatile market changes. In this context, small and medium-sized enterprises (SMEs), which are integral components of the fashion supply chain, often face significant market pressure, leading to losses and even bankruptcy, which in turn causes delays across the entire supply chain. Thus, there is an urgent need for these businesses to adopt new technologies to reduce risks and achieve profitability. Although there have been attempts to introduce blockchain technology into the fashion supply chain, most of these efforts are still in the preliminary stages, with operations continuing to follow old methods. Therefore, this study aims to introduce an evaluation mechanism into the fashion supply chain, encouraging a collective maintenance of interests among SMEs. The main contribution of this paper includes the introduction of a set of innovative management evaluation mechanisms and collaboration models for SMEs in the fashion supply chain, with the goal of securing their rights to autonomous pricing and promoting healthy competition in the forthcoming Web 3.0 era. We implemented the enterprise-level consortium blockchain framework, Hyperledger Fabric. Through testing, it has been proven that the platform is effective and usable in ensuring data integrity and source transparency.

The article introduces a proof-of-concept (PoC) that demonstrates the management of Internet of Things (IoT) devices' infrastructure via smart contracts, facilitating their interaction with the blockchain through gasless transactions. The focus is empowering IoT devices to autonomously sign transactions using their verified private keys, eliminating the necessity for external wallets and enabling blockchain interaction using Biconomy without incurring gas fees. In this PoC, managers can validate IoT devices, permitting them to transmit transactions securely without being able to manipulate measurements or risking losing crypto assets in case of hardware malfunctions. This innovative method ensures that devices with minimal funds can access sensor data and communicate with a smart contract on the blockchain to update information utilizing account abstraction. Detailed workflow and simulation results are provided to showcase the practicality and advantages of this approach in scenarios demanding seamless automated blockchain engagement through IoT devices. The PoC code is openly accessible on GitHub, enhancing the transparency and accessibility of our research outcomes.
