“…Each contributing in saving the data outside the blockchain while corresponding data are being stored in blockchain to verify the original off-chain data. For instance, Babu et al [7] used MongoDB to store electronic healthrecords (EHRs) while its hash value with some patient information will be stored in the blockchain. Yang et al [8] proposed a solution to save data of the products into two parts, the first part called public data which will be saved in relation database where the private part of the data will be stored in the blockchain.…”

The growing popularity of the most current wave of decentralized systems, powered by blockchain technology, which act as data vaults and preserve data, ensures that, once stored, it stays preserved, considered to be one of the most promising safe and immutable storage methods. The authors of this research suggest an on-chain storage framework that stores files inside blockchain transactions using file transforming, chunking, and encoding techniques. This study investigates the performance of on-chain file storage using a simulated network blockchain environment. Test files of varying sizes were deployed. Performance metrics, including consumed time in chunking, encoding, and distributing chunks among block transactions, were measured and analyzed. An analysis of the collected data was conducted to assess the framework's performance. The result showed that selecting the appropriate chunk size significantly influences the overall performance of the system. We also explored the implications of our findings and offered suggestions for improving performance within the framework.

Healthcare data is highly sensitive and must be safeguarded. Personal and sensitive data, such as names and addresses, is stored in Encrypted Electronic Health Records (EHRs). This paper proposes a Blockchain-based distributed application platform for Bangladesh's public and private healthcare service providers. The proposed application framework enables users to create secure digital agreements for commerce or collaboration by leveraging data immutability and smart contracts. As a result, all stakeholders can collaborate securely over the same Blockchain network, taking advantage of their data's openness and read/write nature. The proposed application is made up of various application interfaces for various stakeholders. The proposed solution employs Hyperledger Fabric and Blockchain to ensure data integrity, privacy, permissions, and service availability. In the application portal, each user has a profile. The creation of a unique identity for each user, as well as the establishment of digital information centers across the country, has greatly aided the process. This application collects health data from each user in a systematic manner, which is useful for research institutes and healthcare-related organizations. For this application, a national data warehouse in Bangladesh is feasible, and various healthcare-related analyses can be performed using the collected data, assisting the strategy and planning department in making informed decisions regarding the healthcare sector in Bangladesh. Because Bangladesh has both public and private healthcare providers, a simple digital strategy is essential for all organizations to accomplish their services. This study proposes a solution to achieve this goal.INDEX TERMS Distributed ledger technology, integrated healthcare, blockchain, smart contract, hyperledger fabric, blockchain in healthcare.

“…In addition to the above advantages, blockchain is evolving towards refinement according to needs. Examples include mechanisms that incorporate artificial intelligence techniques to discriminate behaviors [43], thus identifying, for instance, Ponzi schemes [73]; a peer-to-multipoint approach to data transfer [47]; the introduction of a draft smart contract to create smart digital protocols between blockchain participants [49]; securing payments [50]; security verification, such as identity verification during the COVID-19 epidemic [51]; further refinement of elections and voting [54,62]; penalty mechanisms for malicious behavior of participants [56,57,65,66,68,74]; energy transactions [57]; Internet of Things (IoT) monitoring [60]; anti-fraud functionality implemented using Bitcoin payment platforms before being verified by central aggregators [63]; solving compatibility issues in industrial requirements, generating alerts, processing contracts, events, and certificates [64]; proving ownership of customers/healthcare providers [65]; combining other technologies such as artificial intelligence [44], proposing new blockchain paradigms [67] and interoperability with emerging progressive technologies within the blockchain, such as decentralized prophecy machines and sidechains [74]; enhancing the searchability of information within the blockchain [69]; using smart contracts to control the process [75]; using a shapley-valued profit-sharing mechanism [77]; supervisory functions shared by all nodes [47,70]; and no dependence on third-party organizations [50,63,69].…”

Faced with the impact of the coronavirus disease (COVID-19) pandemic, governments must protect the well-being of the population. Aside from considerations, such as keeping the virus from spreading and treating patients, the government should also be concerned about the mental health of its citizens during the epidemic. This study aimed to help users who develop depression due to COVID-19 on social media, reduce the cost of counselling, and reduce the need for users to visit the hospital for counselling. This study investigated the opportunities for blockchain technology to provide psychological help to social media users suffering from depression caused by the pandemic. Blockchain-based technology has been used to develop a new model that enables a user autonomy system to allow users to control their own data fully. The model utilizes a delegated proof of stake consensus blockchain to manage depression data to enable low cost and information security while discussing aspects related to trust, privacy, interoperability, and integration with other information communication technologies. The blockchain framework has been proven to provide secure and reliable information management that meets the user requirements for information autonomy. The framework can be combined with various other information technologies to extend its functionality further. Blockchain, privacy, user autonomy, depression, social media. INDEX TERMS
