most important developments in the crypto world: NTFs and smart contracts

Crypto has three real-world uses.

1) Secure real-time highly available international settlement system

2) A public provable ownership register (NFTs)

3) A trustless finance system which allows entities to sign into enforcable contracts without ever knowing or trusting each other

Currently, NFTs are finding use in the gaming world for representing true ownership of game assets (which can then be sold rented etc). Trustless finance is used in distributed exchanges, creating structured finance products (e.g. leveraged staking), or even implementing game logic (e.g. renting NFTs).
