Blockchain Can Be Described As An Immutable Ledger Logging Data

Blockchain can be described as an immutable ledger, logging data entries in a decentralized way. This new innovation has been proposed to disrupt a wide range of information-driven sectors, including the health domain. Transactions are secured and reliable due to the utilization of cryptographic standards. Recently, blockchain technology has gained popularity and penetrated various fields, particularly due to the rise of cryptocurrencies. One area where blockchain technology holds significant potential is healthcare, owing to the need for a more patient-centered approach to healthcare systems and the integration of various systems, increasing the accuracy of electronic health records (EHRs).

The aim of this work is to explore the potential applications of blockchain technology in healthcare while highlighting the challenges and future directions of blockchain research in this sector. Initially, relevant background information will be discussed, followed by a detailed description of the methodology employed in this study. An analysis of the outcomes will be provided, which includes a bibliometric overview, an examination of the compiled data and its properties, and the results of a literature quality assessment. Lastly, a discussion of the findings from this investigation will take place.

The results indicate that research on blockchain technology in healthcare is increasing, primarily focused on data sharing, management of health records, and access control. Various scenarios are relatively rare. Most research is aimed at presenting novel structural designs in the form of use cases, such as sharing electronic medical records, processing health insurance claims, remote patient monitoring, and securing trustworthy clinical data. This work also addresses the challenges and opportunities faced in future developments. Blockchain technology has been increasingly influencing all aspects of Information and Communications Technology (ICT), with its adoption growing rapidly in recent years.

The interest and growth of this technology have predominantly been propelled by the significant value increase of cryptocurrencies and substantial venture capital investments in blockchain startups. It is forecast that the market for blockchain technology will continue to expand. As of now, there are over 1,500 cryptocurrencies, created within a few years of Bitcoin's introduction, the pioneering digital coin. Bitcoin ensures that transactions occur in a decentralized manner without the need for a trusted central authority. Public keys are utilized, eliminating the need to disclose an individual's identity. A crucial element of the Bitcoin network is miners, who receive coins for their computational work in verifying and storing transactions within the Bitcoin blockchain.

Cryptocurrencies are just one facet of blockchain technology's potential applications. Essentially, three concepts must be distinguished in cryptocurrency: the blockchain, the protocol, and the currency. A coin can implement its own currency and protocol but utilize another coin’s blockchain, like Bitcoin or Ethereum. In the cryptocurrency landscape, blockchain serves as a distributed ledger documenting all completed transactions. Consequently, such blockchains continually expand as new blocks are appended over time.

Most prominent cryptocurrency blockchains are public, allowing users to query their transactions through various web platforms such as blockchain.com, which provides insights into Bitcoin blockchain transactions. Blockchain facilitates transactions between entities without reliance on a (trusted) third-party. It utilizes validators (often miners) to replace these third parties, validating transactions through decentralized consensus. This system addresses the double-spending dilemma—ensuring that a designated amount of digital currency has not been previously spent without a trusted third-party's validation, similar to how banks maintain transaction records and user balances.

While blockchain technology is traditionally associated with the financial industry, its applications extend to various sectors. The underlying infrastructure of blockchain holds immense potential to transform healthcare delivery, medical, clinical, and life sciences due to its broad functionality and unique features as a distributed ledger. The scale of its possible impact is comparable to that of the introduction of TCP/IP. Healthcare providers and biomedical scientists are increasingly drawn to blockchain technology within numerous healthcare domains, including long-term healthcare records, automated claims processing, drug development, interoperability in population health, consumer health, patient portals, medical research, data security, and cost reduction through supply chain management.

It remains uncertain whether blockchain will fundamentally disrupt healthcare; however, healthcare organizations are closely monitoring its potential applications, such as secure patient IDs. The realistic trajectory for blockchain adoption and implementation will be one of gradual evolution; nonetheless, it is crucial to reassess its possibilities in healthcare and biomedical research. Revolutionary solutions arising from blockchain technology bring us closer to the vision of having every patient record regularly update an open-source, community-wide trusted ledger that is accessible and understandable across organizations, ensuring integrity.

Blockchain technology can facilitate the shift from institution-driven interoperability to patient-centered interoperability. It allows patients to designate access rules for their medical data, granting specific researchers the ability to access portions of their data for designated timeframes. Through blockchain, patients can seamlessly connect with other hospitals to automatically gather their medical data. Furthermore, these functionalities can help uphold the rights of data subjects as defined by the EU General Data Protection Regulation. Commonly, it is assumed that the metadata related to medical records is stored in data blocks rather than the medical records themselves. However, critical information, such as details regarding drug allergies, may be shared via a public blockchain.

Blockchain technology is in a state of continuous enhancement rather than completion, and it faces several substantial obstacles that need resolving before it can achieve widespread adoption in biomedical and healthcare applications. The first challenge pertains to transparency and confidentiality; since all data on a blockchain network is visible to everyone, many believe actual medical data is stored off-chain, retaining only the hash of the tag information on the blockchain. The second challenge concerns speed and scalability; a proof-of-concept study indicates that blockchain transaction processing speeds lag significantly behind conventional systems like credit card processing. Given the immense volume of transactions in healthcare, a revolution in blockchain technology is essential. The last challenge relates to the risk of a 51% attack; while theoretical, it poses a tangible threat, and an evident solution needs to be devised.

Although many assert that blockchain technology could transform medicine and beyond, tangible evidence to substantiate these claims is scarce. What is necessary is not overly optimistic forecasts but rather concrete cases that demonstrate blockchain technology's potential within the healthcare sector.

In summary, blockchain technology stands poised to enact transformative change within the healthcare sector. Its decentralized, secure, and transparent framework supports improved patient-centric services and promotes interoperability across healthcare systems. While challenges exist, such as speed, scalability, and security concerns, the potential benefits of blockchain technology in promoting efficient, trustworthy healthcare practices cannot be understated.
