  1. What does ERC-1155 allow that ERC-721 does not?

    Answer: Minting both fungible and non-fungible tokens in a single contract

    ERC-1155 is a multi-token standard that supports both fungible (like currency) and non-fungible tokens within one smart contract, reducing deployment costs.

  2. A generative NFT collection uses code to create artwork. What is the typical input that determines each unique piece?

    Answer: A random seed or transaction hash at mint time

    Generative NFTs use a random seed—often derived from the minting transaction hash—to deterministically combine art layers and produce a unique output per token.

  3. What is 'gas' in the context of minting an NFT on Ethereum?

    Answer: The computational fee paid to validators for processing the transaction

    Gas is a fee paid in ETH to compensate Ethereum validators for the computational work required to execute and record the minting transaction on-chain.

  4. Which marketplace pioneered the concept of 'editions' for digital art NFTs, allowing multiple copies of the same work?

    Answer: Nifty Gateway

    Nifty Gateway popularized 'open editions' and 'limited editions,' letting collectors purchase multiple copies of the same artwork within a timed sale window.

  5. What happens to an NFT's ownership history when it is transferred or sold?

    Answer: It is permanently recorded on the blockchain as a series of transactions

    Every transfer of an NFT creates an immutable on-chain transaction record, giving NFTs a permanent, publicly verifiable provenance trail.

  6. What is the main advantage of using Polygon over Ethereum mainnet for minting NFTs?

    Answer: Polygon transactions have near-zero gas fees

    Polygon is an Ethereum layer-2 network with extremely low transaction fees, making it practical for artists to mint NFTs without paying high ETH gas costs.

  7. When an artist 'burns' an NFT, what actually happens?

    Answer: The token is sent to an unspendable address, effectively removing it from circulation

    Burning sends the NFT to a null address (0x000...dead) with no private key, making it permanently inaccessible while the on-chain record remains visible.
