Imagine buying a handcrafted bronze mask at a market. Anyone can take a photo of it, but only you hold the certificate from the artist saying, “This is the original.” That’s basically what a NFT is, It is a digital certificate of ownership stored securely on a blockchain. NFT stands for Non-Fungible Token. “Non-fungible” means it’s unique and that there isn’t another exactly like it. “Token” means there’s a digital record proving ownership and history. How NFTs work: NFTs live on a blockchain, which you can picture as a giant notebook everyone can see but no one can erase or change. Each NFT gets its own page with records of who created it, who owns it now, and who owned it in the past. When you buy a NFT, you’re not just saving an image or file, you’re claiming a piece of verified digital heritage that lives permanently online. Why NFTs matter: * They let creators sell directly to collectors without middlemen. * They protect the history and origin of digital art or cultural artifacts. * They allow collectors to hold a verifiable, one-of-a-kind piece of digital culture. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://usiko.gitbook.io/docs/documentation/learn-with-usiko/editor.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
