This study aims to explore Blockchain
technology which is a new technology that has the
potential to alter many sectors by making procedures
more democratic, safe, transparent, and efficient.
Blockchain technology's broad adoption has had a
significant influence on how people deal in the digital
world. The use of blockchain technology has been
expanding across a number of industries as technology
advances. Blockchain is an emerging technology that
enables smart contracts to perform a variety of processes
and different jobs. The foundation of blockchain is smart
contracts, which have the ability to replace the position of
"middle man" as it can reduce costs, minimize delays,
offer more timely and precise data, and improve
reporting accuracy. This makes it incredibly difficult for
hackers to change or breach blockchain data, especially
in a system using a public blockchain. PoC Design is the
name given to the new IoT-PoC development process
based on extreme programming.
Keywords : Blockchain, types of blockchain, Transformation of the financial industry, smart contracts, blockchain, and real business value.
