*3.1.1 Healthcare information organization*

Research on the subject of interoperability between blockchain applications in healthcare can be originated here [14]. The MedRec model [15] provides a proof-ofwork that allows blockchain designs and other decentralization standards to anchor and communicate with other medical record technologies. The architecture is organized using Ethereum smart contracts, which also provides a log that keeps track of medical data and allows users to see entire data, review care records, and exchange information. An innovative approach for structuring open APIs and system structure transparency, as well as conditioning with the supplier's existing framework, has also been described in this study [16]. An adaptive method for processing large-scale personal health data using a tree-like method is proposed [17]. A blockchain-based program has been adopted to secure documents stored in the cloud. A further platform built on the blockchain for healthcare data is BlockHIE [18], which includes off-chain archiving with on-chain validation to guarantee privacy as well as authenticity for records. With the use of blockchain technology, healthcare data may be transferred in a secure and auditable way [19]. Additionally, it employs blockchain to manage access-based health data [20, 21]. **Figure 3** represents the scope of CSP. Lastly, a blockchain-based technology for maintaining patient and physician databases in the field of healthcare analytics is shown. The benefits of a parallel healthcare system are brought in by a methodology that is given in Ref. [22] and is built on artificial systems, computational trials, and then a simultaneous implementation utilizing blockchain technology. To handle health data at the individual and institutional levels, several experts have suggested using private blockchain solutions [23].
