The image-hosting aspect of nonfungible tokens is in need of major improvements. First, people saw NFTs on FTX break after it declared bankruptcy. More recently, NFTs on the marketplace Magic Eden showed some questionable images instead of their actual thumbnails. 

As the problem continues to persist, Cointelegraph reached out to various industry executives to get their thoughts on how NFT projects can solve the issue.

From using dependable blockchains to exploring the storage technologies available in the Web3 space, various executives working in the NFT industry gave their thoughts on how to avoid future problems in NFT image hosting. 

Samuel Huber, CEO of the metaverse platform LandVault, noted that the issue with FTX NFTs was that the metadata was hosted using a Web2 API. According to Huber, the best course of action to avoid this type of problem is to use dependable blockchains for the NFTs themselves and store them on a distributed ledger that is not controlled by a single entity.

The executive also told Cointelegraph that while very few projects currently host the actual images on-chain, it is of paramount importance to make sure that the metadata and files are hosted properly. He added:

“Projects should verify if the platforms are using decentralized hosting providers such as IPFS and Arweave for the metadata and any other files that are linked to the NFT.”

Alex Altgausen, CEO of play-to-earn NFT game Banksters, also agreed with the sentiment. The executive believes that if NFT projects truly want to disrupt traditional industries like gaming, they must explore storage technologies that are already available within the Web3 space.

Altgausen told Cointelegraph that there are new technologies that “distribute file storage using multiple decentralized options.” These allow computers worldwide to store and serve files in a peer-to-peer network, and this removes the dependency on traditional Web2 storage providers like Amazon Web Services or Google Cloud.

When it comes to users, it’s not always simple to check if this could happen to the NFTs they buy. Radek Pléha, co-founder of NFT ticket platform BillionAir, told Cointelegraph that users have to do their own due diligence and research the project’s storage infrastructure. “This can include reviewing the project’s white paper and checking for any security measures that have been implemented, as well as looking for reviews and feedback,” he added. Pléha also said:

“Unfortunately, not all NFTs’ metadata is stored on the blockchain, as main chains may be limited in size and more expensive for data storage.”

On Aug. 5, Jonathan Victor, the Web3 storage lead at Protocol Labs, and Rarible CEO Alex Salnikov also discussed how NFTs don’t live on the blockchain. Victor highlighted that off-chain storage solutions are introduced because of size limitations on main chains. He also highlighted the use of decentralized storage networks for NFT metadata. On the other hand, Salnikov said that NFT transactions are confirmed on the blockchain but that the metadata is typically stored elsewhere.
