## What is an Olympic Pin NFT and why is each one unique?

Olympic pin trading started as a way to identify athletes, judges, and officials, but over the past 125 years it has become an Olympic Games tradition where everyone -- athletes, event staff, journalists, and spectators -- all take part to collect and trade pins in the Olympic Village and beyond.

The International Olympic Committee (IOC) and nWay have turned Olympic pins into non-fungible tokens or NFTs. An NFT is a special kind of cryptocurrency token where each one is cryptographically unique. This means that, like physical collectible pins, there is a limited supply. Each NFT Olympic pin contains identifying information recorded in smart contracts. The smart contract is held on the blockchain with full transparency for anyone to see and verify.
