CKB Weekly #18: NFTs on CKB

Original Article: https://ckbweekly.substack.com/p/nfts-on-ckb

We all know that NFT's have lots of use cases, from in-game items to crypto art, and a long tail of all sorts of records that can be committed to a blockchain: like badges, ticket sales or real estate deeds.

These use cases have a mainstream appeal and we are excited that they are starting to be built on Nervos. During a recent hackathon, a team built an NFT marketplace called Pictosis that takes advantage of some of the unique features of Nervos to improve on the status quo of NFTs today.

To demonstrate: with open transactions, NFT's can be added to a marketplace (and ready for sale) with only a creator-signed transaction being sent to the NFT marketplace. Later a buyer can publish this information on-chain paired with their payment for the NFT. Current NFT creators will see that this resolves UX issues that stem from the current requirement to wait for transaction confirmation and pay for gas before an NFT can be put up for sale.

Additionally, because Nervos is built for Layer 2, we are also looking forward to what Layer 2 innovations the Nervos community can bring to the NFT space, to further improve costs and the industry's ability to scale to serve new NFT users.
