Kirill Emelyanenko (the second person who launched The Open Network along with tolya-yanot) released the first version of the standard for a smart contract for NFT.

The NFT protocol standard was recently released on his github.
Link: github.com/EmelyanenkoK/nft-standard-draft

This protocol is based on the original smart contract from the TonWhales team, but has several new features:

1. The editor role has been added. The contract code and the content of the NFT can be changed by the editor after its publication!
The editor_address field has also been added to the information about NFT.

2. Collections smart contract standard has been added, which can publish and manage an entire group of participants using a single NFT smart contract.
The NFT group members will differ from each other by an ordinal number.

The bright NFT-future in TON is coming!
