But first, what is Blockchain?

Blockchain technology allows for the creation of a decentralised public record of digital information. The data is stored in a public database and can consist of any information. It is the first digital technology that offers a way for unsecured parties to refer to a common, indelible digital record. Blockchain already has many varied applications, and heres some examples:

1.BitcoinOne of the more famous examples of Blockchain in action is Bitcoin. This is a digital currency . This entirely electronic form of funds can be transferred securely directly from user to user without the need for intermediaries – essentially there is no central bank or administrator needed. Bitcoin is not the only currency based on Blockchain technology. Bitcoin Atom is a fork of Bitcoin and provides a truly decentralised way of exchanging cryptocurrencies without trading fees and no exchange hacks.

2.SpotifyFollowing acquisition of Mediachain Labs in late 2017, Spotify are using a decentralised database to correlate artists with license agreements and tracks. Use of Blockchain in music looks to create a more transparent record of rights ownership that will solve long-standing issues within the industry, whereby artists and labels have not been fairly acknowledged.
