# Onchain Technology The team have opted to take an “On-Chain” minting technology approach for the NFT collection in which unlike off-chain, where NFTs are stored outside the blockchain, on-chain NFTs are NFTs where all data used to create the image is stored inside the smart contract on the blockchain instead of storing just a url that points to an image stored somewhere else that can be taken down at any time. Off-chain NFT data is usually stored outside the blockchain in places such as on the cloud, centralized hardware server storage, or IPFS. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://whitepaper.onchainlandmark.com/summary/onchain-technology.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
