NBA Top Shot : It is an online-only marketplace where users can buy, sell and trade NBA highlights. These highlights, or “moments,” are owned by users through a unique number. They’re basically virtual sports cards, but instead of a picture of a player with statistics on the back, you get a video highlight of a play like a LeBron James dunk or a Steph Curry 3-pointer.

The NBA has NBA Top Shot – a way of selling digital collectibles in the form of trading cards embedded with iconic moments from the game. With a plan to add virtual jewellery, accessories and clothing that can be used across social media, the NBA is seeking to find ways to expand this revenue stream as far as it can go.

I started building a small app myself. Nothing that ever will go public. It is just a small privat project to help me understand a few things about flow and cadence better. I was already able to get all the information about the plays from this contract and put it into a csv.

FLOW token is a contract, which implements Fungible Token Standard interface. If you take a look in the code, you will see that on the higher level totalSupply is defined on implementing contract, but it doesn’t know how much tokens holds each individual account. Each account that would want to own tokens would need to have an instance of the Vault resource stored in their account storage. The Vault resource has methods that the owner and other users can call. Those methods are limited byProvider, Receiver, and Balance resource interfaces. These interfaces declare pre-conditions and post-conditions that restrict the execution of the functions in the Vault.
