Aim: The study aims to look at college students' perceptions about cryptocurrencies and its future in India.
Background: Bitcoin, Litecoin, Etherum, and Ripple are examples of distinct types of cryptocurrency. In 2008 the invention of bitcoin was introduced by an unknown person or a group which is named Satoshi Nakamoto.
Methods and Materials :The survey on awareness about the cryptocurrency and its future in India among college students was conducted using google form link in the  year 2020 . We have distributed our survey to 100 college students. SPSS software was used to collect, tabulate, and statistically analyze the replies.
Result: From the obtained data it is evident that 91.74 % are  aware of cryptocurrency whereas 8.26  % are still not aware about the cryptocurrency. From the study population 73.39 % agreed cryptocurrency has a future in India and only 8.40 % agreed it'll be useful in future.
Conclusion : The findings suggest that the majority of the college students are aware of cryptocurrency but they lag in the knowledge of its usability. Very few participants only agreed that cryptocurrency has a future in India. It is the duty of the Government and crypto agencies to enhance its usage in India for safe and secure use of this virtual money.

Medical Infrastructures are viewed as a potential case in the area of improvement intended for IoT applications. The medical requirements regarding the patient is continuously monitored at any convenient place and directed to the physician spontaneously without any human intervention. As a scientific mathematical instrument, hypergraphs can be instigated to exemplify computer networks, biological networks, data structures, and various other systems. Hypergraphs are often used, to map the objects in the system and the complex relationships between them. Blockchain can be considered as a chain or records stored in the forms of blocks which are controlled by no single authority, which contains transactional records, ensuring security, transparency, and decentralization. Blockchain is completely open to everyone on the network as it is a distributed ledger. Each transaction on a blockchain is fortified with a digital signature that proves its legitimacy. While transactions take place on a blockchain, there are nodes on the network that legalize these transactions. Due to the use of encryption and digital signatures, the data stored on the blockchain is tamper-proof and cannot be transformed. In blockchain, the nodes are called as miners and they use the concept of Proof-of-work, in order to process and authorize transactions on the network. In order for a transaction to be valid, each block must refer to the hash of its preceding block. Blockchain consists of different consensus algorithms securing it from cyber-attacks.
 

The rise of online learning nowadays, encourages learning patterns have to move from face to face to the network. This trend has become one of the easy alternatives for many of the general public to be able to learn or conduct training based on online and in the end, they can get a certificate after participate into that online training. BINUS as one of the tertiary institutions that has implemented online learning and has a learning website to support it. But along with the convenience available, easy access to learning, online learning activities need to be recorded as well, for example: behavior of learners, activities including attendance, and quizzes need to be recorded to avoid fraud. Fraud in manipulating attendance, or in activities carried out on the learning page. One of the most popular technologies being discussed today is Blockchain, and its can be utilized to support a better learning system. Readiness in applying this technology will be measured using the Technology Readiness Index (TRI) method.

In article the author results the analytical analysis of analogies and differences between two dynamical technologies - relational databases and blockchainа. If the technology of relational databases was applied at construction of information systems of the electronic government, technology blockchainа rather new to digital economy being the new engine of the electronic government. The comparative analysis of these technologies on several parametres is carried out, are specified their strong and weaknesses. Primary factors on which the technology choice should be carried out, depending on the purposes of solved problems in digital economy are specified.
