The world as we know of today has changed a lot in the recent
past. Historians believe that more technological advancements and
progress have been made in the last fewdecades than as compared
to the entire history of humanity of thousands of years.
Our belief is we owe a lot of this progress to revolutionary
technologies like the internet, AI, machine learning, data sciences
and the one and only blockchain. While all the othertechnologies
help our world transition to a digital world, it
is blockchain, which holds this digital world together and
provides the security needed to build our confidence in the
digital world.
While blockchain has left no industry alone, it has
influenced the finance industry the most. Blockchain has
entirely changed the way finance industry worked.From the
decentralized finance applications to fungiblecurrencies,
nothing is left unaltered. However, in this paper we are
going to focus on something different, something new –
Non-fungible tokens.

Pragma version0.8.15 (#1) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.15 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
