because sometimes doctors at different physical locations need to take a combined decision or want an opinion from another expert. This process should confirm that communicating entities are receiving up-to-date information. This exchange should take place in a secure and authenticated process [1]. The security and privacy of the data are the primary concerns for any health data exchange. Furthermore, severe interoperability concerns plague this field on a regular basis. Extensive, trustworthy, and healthy engagements between the parties involved are required for such clinical data transfers. The innovations and latest breakthroughs in technology have made it easy to witness improvements in the health sector domain. The medical sector's current capabilities may be enhanced further by using the most cutting-edge and innovative computer technology. This cutting-edge computer technology can aid doctors and medical professionals in the early detection of a variety of ailments [2]. These powerful computer technologies can also greatly increase the accuracy of detecting illnesses at their early stages. Various developing and innovative computer technologies are already being applied with spectacular outcomes in other industries, among them blockchain technology, IoT, artificial intelligence, etc. Because of the centralized nature of the current system, security remains a source for worry. As a result, security may be provided via a new and growing technology called blockchains [3; 4; 5; 6]. By identifying the limitations of existing security procedures, blockchain technology may be used to improve security. It is a decentralized point-to-point network that removes the need for an intermediary in transactions and communication [7]. All of the transactions are self-contained and separate from one another. Blockchains are the technology that underpins the popular and ground breaking notion of cryptocurrencies. Everyone has access to blockchains, which are a publicly distributed ledger system [8; 9; 10]. The blocks in the chain consist of data, a hash of the preceding block, and the hash of all the transactions [11; 12; 13]. It is divided into two sections: the header and the transaction information. The block's information is contained in the header. The \"timestamp\" keeps track of when the block was generated. The \"difficulty level\" determines how difficult mining a block will be [14]. The hash of all the transactions of the current block is represented by \"Merkle tree root\", and \"NONCE\" is the answer to the proof-of-work algorithm's mathematical problem. Figure 1: Different Stakeholders in the healthcare management ecosystem. Motivation, Objective, and Contributions  
In this article, the application of an emerging technology in the healthcare field is discussed. In healthcare, blockchain technology can help with drug traceability, medical record management, and other issues. The healthcare sector is facing lot of difficulties due to the vulnerability of healthcare data to security threats such as assaults on truthfulness, confidentiality, and availability. As a result, blockchain technology may be used in healthcare to improve the sector's capacities, while also ensuring the confidentiality of patients' information. However, the introduction of new and evolving technologies in any industry can result in a number of concerns and obstacles. So, identifying such concerns and obstacles is critical, particularly in the healthcare industry, where human lives are closely linked. The feasibility of adopting blockchains in the healthcare sector is investigated in this article. Contributions made by this article are listed below. * Various issues in the healthcare industry are explored and the benefits of integrating blockchain technology in the healthcare industry are discussed. * A blockchain-supported, decentralized access control solution is proposed and implemented. Moreover, it can be tailored for implementation on other blockchain frameworks.
