The Magic Behind NFT Platforms 06:00pm - 06:35pm CTOs and Product Managers from a number of prominent tokenized art marketplaces will discuss their experiences in designing and building a product to maximize user experiences. From decentralized media storage and front-end design to innovative smart contracts and extensive testing, the panel shares some of the biggest challenges and most rewarding successes they witnessed throughout a long and intensive process. ### Points to note * Improvements in **file storage** * IPFS is great but not perfect * Other solutions are still immature but getting better * Data longevity * file size limitations * load times, generally making paletable experience for collectors and artist * more interactive and richer media types expected/wanted * Handling **mixed media** * Transcoding pipelines * Formats are not always supported in all browsers/phones * Maintaining the original quality but making it more accesible is a challenage * **Standards** are needed and still evolving * Most follow the OpenSea standards on **metadata** but really different domains require different standards i.e. art vs gaming most likely need different standards * **Secondary sale roylaty standards** are still missing * **EIP-2981** trying to get to the bottom of this problem * **transparency** for minting and token purchases * being able to track token movements and prices will be benfical in the future - no agregation here * Spotting deep **fakes** * how to reliability do this * **GAS** is a problem full stop * **immutablex** and other rollup based solutions on the cards * transaction * **Mobile** first UX is getting more important * WalletConnect enabling wallet less web3 access from normal browsers * **Large attack** surface * smart contacts and all the secuirty concerns they bring * all web 2 era security considerations need to be though about * key management * artist key management * Identity if key * **Uploading large files** on poor connections * dependant on internet access * same for page load speeds * Success * improved artwork handling for social channels was a big win, lots fo effort went into that * Caching layers are king * UX and page speed still need to be quick
