More than hundred countries have experienced WannaCry Ransomware cyber-attack in 2017. This attack demanded around $300 of Bitcoin cryptocurrency from users to retrieve their data. There onwards, Blockchain technology and cryptocurrency are catching the attention of everyone. Blockchain is a growing digital record keeping register in the distributed form which cannot be altered. In case of Blockchain, no central authority is needed. Modification of the data or assets stored on Blockchain is highly difficult or nearly impossible. All the data available on Blockchain can be publicly seen by everyone. It cuts down the excessive costs required in the conventional manual record keeping registers. Blockchain technology has lot of bonus points including integrity, write access, reduced cost, trust, etc. With Blockchain technology, various tokens are available such as currency tokens, asset tokens, utility tokens, and equity tokens.
