A blockchain is a distributed database of records, or public ledger, of all transactions or digital events that have been completed and shared among participants. Each transaction in the public ledger is double-checked by a majority of the system's members. Information can't be deleted once it's been entered. Every transaction ever made is recorded in the blockchain, which is certain and provable. The most well-known example of blockchain technology is Bitcoin, a decentralized peer-to-peer digital currency. Although the digital currency bitcoin is divisive, the blockchain technology that underpins it has performed well and has a wide range of uses in the financial and non­financial sectors. The basic idea is that the blockchain creates a distributed consensus system in the digital online world. By producing an irrefutable record in a public ledger, involved entities can be assured that a digital event occurred. It makes it possible to transition from a centralized to a democratic, open, and scalable digital economy. This innovative technology offers great prospects, and a revolution in this field is only getting started. This white paper introduces blockchain technology and some of its most attractive applications in the financial and non­financial sectors. Then we look at the problems and opportunities that this foundational technology, which is poised to alter our modern world, presents.
