# Welcome to Spaceship Earth. We are talking about a world full of Non Fungible Tokens (NFTs) of all types and colors, as a new standard, a world of tokenized assets both physical and abstract while much favouring the arts. Prior to to Bitcoin's Blockchain it had been unthinkable to trust on line security, everything digital being copiable. The inception of Bitcoin's Blockchain bestowed, for the first time ever, programmable digital uniqueness, despite being on-line, and which presents us all with a new paradigm to appreciate and use. What is a Non Fungible Token (NFT)? *It represents unfakeable digital uniqueness, underpinned by an unfalsifiable consensus network beyond the reach of any bad actor or group of actors.* The purpose of this white paper is to present a complex subject as lucidly as possible. The markets that these NFTs will infiltrate are many and infinitely diverse, and the eventual use cases are impossible to even imagine for now. Who could have imagined the monetization of Youtube at the beginning of the Internet? Or the piston engine at the beginning of the wheel? What we are experiencing with NFTs is the same. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
