Blockchain technology (BCT) is an evolving digital technology that changes digital operations' dimensions by conducting distributed ledger transactions without the involvement of third parties. The chapter aims to examine the use of BCT in healthcare and develop a hierarchical theoretical framework. The framework is based on the stakeholder principle and exposes BC's effect on smart healthcare. Its decentralised existence is an ideal catalyst for the much-needed transition toward well-organised healthcare as it solves the most pressing issues.

Possible scenarios for using blockchain technology in the field of education are considered. Methods and technologies of tokenization of assets, related to the educational process, are investigated. It is concluded, that the blockchain technology is decentralized and transparent with a high degree of reliability, which ensures the equality of all users of the chain's services. The transparency of the technology guarantees the participants in the process against abuse and forgery of documents. The study of the features of smart contracts made it possible to form the advantages of smart contracts in the field of education. This is, first of all, the conclusion of agreements without the participation of third parties, as well as the security and confidentiality of agreements. This ensures that the terms and subject of the agreement are kept secret, and that no one else can amend the agreement. At the same time, storing the contract in encrypted form ensures its confidentiality. A decrease in the cost of operations was noted. Tokenization of educational assets is considered on the example of preparing and defending a thesis with the subsequent registration of a diploma. The processes of passing the thesis in the context of using blockchain technology and issuing smart contracts are considered in detail. The advantages of using blockchain technology and smart contracts are illustrated with specific examples. A study of the means and mechanisms for ensuring the confirmation of the authenticity of educational documents, the confidentiality of students' personal cards, and student identification has been carried out. To create a decentralized distributed ledger for tokenization of educational assets, it is proposed to use blockchain technology and smart contracts based on the Ethereum platform

Newly emerging cryptocurrencies and blockchain technology present a challenging research problem in the field of digital politics and economics. Bitcoin—the first widely implemented cryptocurrency and blockchain architecture—seemingly separates itself from the existing territorial boundedness of nation-state money via a process of algorithmic decentralisation. Proponents declare that the utilisation of cryptography to advance financial transactions will disrupt the modern centralised structures by which capitalist economies are currently organised: corporations, governments, commercial banks, and central banks. Allegedly, software can create a more stable and democratic global economy; a world free from hierarchy and control. In Money Code Space, Jack Parkin debunks these utopian claims by approaching distributed ledger technologies as a spatial and social problem where power forms unevenly across their networks. First-hand accounts of online communities, open-source software governance, infrastructural hardware operations, and Silicon Valley start-up culture are used to ground understandings of cryptocurrencies in the “real world.” Consequently, Parkin demonstrates how Bitcoin and other blockchains are produced across a multitude of tessellated spaces from which certain stakeholders exercise considerable amounts of power over their networks. While money, code, and space are certainly transformed by distributed ledgers, algorithmic decentralisation is rendered inherently paradoxical because it is predicated upon centralised actors, practices, and forces.

Blockchain is a digital, distributed, and decentralized network to store information in a tamper-proof way with an automated way to enforce trust among different participants. An open distributed ledger can record all transactions between different parties efficiently in a verifiable and permanent way. It captures and builds consensus among participants in the network. Each block is uniquely connected to the previous blocks via a digital signature which means that making a change to a record without disturbing the previous records in the chain is not possible, thus rendering the information tamper-proof. Blockchain holds the potential to disrupt any form of transaction that requires information to be trusted. This means that all intermediaries of trust, as they exist today, exposed to disruption in some form with the initiation of Blockchain technology. Blockchain works by validating transactions through a distributed network in order to create a permanent, verified, and unalterable ledger of information.

Blockchain, which is also called a distributed ledger technology (DLT), is an emerging and ever advancing technology having flourishing potential for nourishing and revolutionizing higher education. It stems in decentralization and distributed learning with characteristics of permanence of records, pursuit and transfer of knowledge, authority of institutions, and reliability of teaching and learning. These characteristics of blockchain attract educational institutions particularly the higher education institutions to adopt it. However, in spite of all potential and benefits of blockchain technology, the higher education stakeholders currently seem to be less aware of the social benefits and educational/instructional potential of blockchain technology. It can be addressed through proper advocacy and campaign. The complete chapter will demonstrate possibilities of blockchain technologies in higher education along with its issues and challenges.

Blockchain is an online decentralized and distributed ledger technology that has the ability to keep and track records in a safe, verifiable, and transparent manner. More significantly, it has an infrastructure that is compatible with Web 3.0, which offers great potential for lifelong learning. This chapter explains the different modalities of learning (formal, non-formal, informal), blockchain technology, and its current use in educational processes. Based on the findings, the authors suggest that blockchain technology can be used to connect and interlink different educational experiences that occur in different educational modalities, enabling us to evaluate educational processes holistically and thus promote lifelong learning through the use of cutting-edge technologies.
