You can issue an NFT token for your nickname, which will remain on the blockchain and will be linked to your nickname page and certificate.
An NFT nickname (non-fungible token) is a record in the Ethereum blockchain with a link to the nickname's NFT certificate and the nickname itself.
An image of an NFT certificate for a nickname, the link to which will be recorded in the blockchain, will also be displayed on your nickname page as an additional certificate.
After you have registered a nickname, you can order the issue of an NFT certificate. Issuance is possible for any certificate level.
In developing. The launch of the tokens is expected in 2021.
