Blockchain is a type of distributed ledger in which value exchange transactions (in bitcoin or other token) are sequentially grouped into blocks. Each block is chained to the previous block and immutably recorded across a peer-to-peer network, using cryptographic trust and assurance mechanisms. Depending on the implementation, transactions can include programmable behaviour.1

Digital log of transaction details created

Distributed to nodes with cryptographic digital signature

Competition among the distributed nodes to validate transaction to reap economic benefits

Traditional business models are being affected by innovations such as Blockchain technologies. Businesses need to be proactive and innovative so they can be sustainable and competitive. Enterprises are willing to invest in innovations and digital transformation, in order to meet customer demand and stay ahead of the game.
