Blockchain is a new and upcoming transforming technology designed as a complete decentralised
system. The “Block” represents a set of records that needs to be saved and the “Chain” links those
blocks together for security purpose with the help of hashing function. Blockchain is simply a
database containing transactions validated by network community instead of a single centralised
authority. After validation, the data in the form of a block is linked to the previous block, hence
creating a Blockchain. Blockchain gained its recent popularity because of its applications like Bitcoin
and Ethereum. The report should cover the following points:
? Define Blockchain and discuss how Blockchain works.
? Explain the security features of Blockchain and its advantages.
Students need to read four to five articles about two Blockchain Applications to explore how these
applications work and their different features. Students have to research two Blockchain applications
and complete Task 1 and Task 2. The two Blockchain applications are assigned to students as per the
following list and Table 1.
