Ah, Motoko Ghosts NFTs! These were part of the early days of the Internet Computer (ICP) ecosystem. Here’s what I found:

Origin and Design:

Motoko Ghosts were a collection of 10,000 unique NFTs designed by Poked Studios.
They were airdropped in 2021 to participants of the NFT.NYC conference and members of the ICP community via DSCVR.
Purpose and Utility:

Owning a Motoko Ghost NFT entitled you to a 1:1 airdrop of $MOTOKO tokens, creating a connection between the NFTs and the Motoko token.
There’s discussion about the potential for future utility within the SNS DAO related to $MOTOKO, but specifics are limited.
Some speculate about future value based on their limited quantity.
Here are some resources you can explore for more information:
