Today, blockchain is becoming more popular in academia and industry because it is a distributed, decentralised technology which is changing many industries in terms of security, building trust, etc. A few blockchain applications are banking, insurance, logistics, transportation, etc. Many insurance companies have been thinking about how blockchain could help them be more efficient. There is still a lot of hype about this immutable technology, even though it has not been utilised to its full potential. Insurers have to decide whether or not to use blockchain, just like many other businesses do. This technology keeps a distributed ledger on each blockchain node, making it more secure and transparent. The blockchain network can operate smart contracts and convince others to agree, so criminals cannot make mistakes. On another side, the Internet of Things (IoT) might make a real-time application work faster through its automation. With the integration of blockchain and IoT, there will always be a problem with technology regarding IoT devices and mining the blockchain. This paper gives a real-time view of blockchain—IoT-based applications for Industry 4.0 and Society 5.0. The last few sections discuss essential topics such as open issues, challenges, and research opportunities for future researchers to expand research in blockchain—IoT-based applications.

Developing technologies, advancement in science, evolving globalized perspectives and the massive dependence on digital platform for a routine sustenance has led to the core building of Industry 4.0. In general, industry 4.0 focuses on the metamorphosis of all industrial components with the help of strong digital support. It's very often interlinked with the successful fourth industrial revolution. It is to be noted that the very fourth outburst of industrialization plunges forward in order to achieve an optimized and sustained form of production. With the uplift of the fourth generation of this stirring revolution, the efficient extraction of advanced informatics analytics along with internetworked machines have grown to a great extent, complementing the digital platform. On the other hand, society 5.0 involves a human centric community which is capable of striking a balance between the economical proliferations and resolving societal liabilities by the core combination of cyber and physical space. Just like how industry 4.0 carries out the digital transformation of every industrial perspective, society 5.0 encourages mundane life to leap towards a digital revamp expanding across different tiers of the community. Indeed, the rapid change of information and Communication Technology along with the portrayal of society 5.0 as a global trend and a key aspect of the Science and Technology Basic plan, the interplay of the two proves to be a constant support for each other. This paper discusses about the future look of industry 4.0 and society 5.0 and elaborates on the challenges and opportunities rooted from them.

Industry 5.0 is the subsequent stage in the development of manufacturing and production systems that combines cutting-edge technology with human intelligence and skills. The healthcare sector has been developing over time, going through significant changes at every stage. The emerging idea of Industry 5.0 in the healthcare sector, also known as Healthcare 5.0-and its potential applications in the healthcare sector are examined in this study. Healthcare 5.0 makes use of cutting-edge technologies to revolutionise healthcare delivery, improve patient outcomes, and improve the healthcare experience as a whole. Industry 5.0 places a strong emphasis on the integration of humans, machines, and technology in the manufacturing industry. The study discusses Healthcare 5.0's potentials and opportunities, including personalised medicine, sophisticated diagnostics, telemedicine, and more patient-centric care, all of which are made possible by the application of cutting-edge technologies like Artificial Intelligence (AI), blockchain, big data analytics, and robotics. The study also discusses the difficulties and problems that must be solved for Healthcare 5.0 to be implemented successfully, including data security and privacy, ethical and legal issues, the need for appropriate skills and training for healthcare professionals, and cost-effectiveness.
