# Why Blockchain? AIRTIST is an NFT ecosystem of digital arts that are generated with AI algorithms. The essence of an NFT is the smart contract with a smart contract ID that marks the ownership of the digital asset. But simply using distributed training and distributed storage is not sufficient to create a decentralised NFT ecosystem as we also need to introduce blockchain and decentralised governance mechanisms to ensure: (1) The ownership of NFT is confirmed and recorded on the Blockchain (2) NFT transactions are executed by smart contracts on the Blockchain (3) Essential activities such as changing system parameters and making essential decisions be managed through the consensus mechanism on the Blockchain (4) Implementation of an incentive system for the participants and contributors Consequently, the AIRTIST community can also be governed with a DAO architecture in the long run. --- # 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.
