Understanding Flow and Cadence

Flow is a specialized blockchain designed for open worlds, offering seamless transactions and enhanced user experiences. You can explore more about it here. Cadence, on the other hand, is a resource-oriented programming language specifically developed for the Flow blockchain, making it an ideal environment for creating Non-Fungible Tokens (NFTs).

How to Deploy and Test the Top Shot Contract in VSCode

Follow these steps to deploy the Top Shot smart contracts:

• Start the emulator using the “Run emulator” command in VSCode.
• Open the NonFungibleToken.cdc file and the TopShot.cdc file for reference.
• Deploy the NonFungibleToken contract first.
• Next, import NonFungibleToken into the TopShot contract.
• Deploy the TopShot contract to a new account.

How to Run Transactions Against the Top Shot Contract

Executing transactions against the contract can be achieved either using Flow CLI or through VSCode. Here’s a brief guide:

Using Flow CLI:

• Install the Flow CLI and emulator.
• Initialize the flow emulator’s configuration.
• Deploy both the NonFungibleToken and TopShot contracts.
• Use the Flow CLI to execute commands for creating and interacting with sets and moments.

Troubleshooting Your NBA Top Shot Experience

While engaging with NBA Top Shot, you may encounter some challenges. Here are a few troubleshooting ideas to get you back on track:

• Ensure you have the correct versions of Flow CLI and the VSCode extension installed.
• Check that all import addresses are accurate in your contracts and scripts.
• If transactions fail, confirm that the Flow emulator is running and synced properly.
• Adhere to best practices defined in the Cadence documentation for smoother operations.

An Analogy to Understand the Code Structure

Think of the NBA Top Shot digital collectibles and smart contracts like an intricately designed library. Each book represents a Moment, and within the library’s walls, all books are organized in special sections (Sets). Librarians (Admins) oversee the issuing (Minting) of new Books (Moments) and ensure the right cataloguing (Metadata) is in place. When a reader (User) wants a specific book, they simply go to the librarian and make their request. The librarian ensures that the books are not lost in the stacks, facilitating a perfect transaction.

Conclusion
