Blockchain is a virtual, public ledger (decentralised) that records everything in a secure and transparent manner. Unlike banks that facilitate (centralised) transactions with traditional currencies, the blockchain allows the free transfer of currency through a decentralised environment.
In Short it is nothing but a shared, immutable record of peer-to-peer transactions built from linked transaction blocks and stored in a digital ledger.
Blockchain is still a nascent technology compared to the existing database systems. Until this technology becomes commoditised, you’ll need to rely on experts (which are still few in number) to help you it. While there are a lot of companies replacing their current systems with a blockchain, it’s still not mainstream. Codebrahma is one of the early adopter of the blockchain technology
