GEM SCORE
How is it calculated

Where are the attributes?

Off blockchain

The attributes are hosted on several computers via IPFS protocol.

IPFS is a distributed system for storing and accessing files or assets. This is not a blockchain. You can see more information here.

No. To be sure about the persistence of the data, you need someone to "pin" your data on IPFS nodes. In most cases, the NFT platform does it for you.

You partially lose your duo

Everai chose to put the attributes and the other data on a distributed & decentralized protocol: IPFS. Even if this is not the best practice to guarantee data availability, this is better than choosing private storage.
If Everai dies & IPFS survives, you will be able to retrieve this data.

The data hosted on IPFS needs to be "pinned" to be available. If not, it can disappear at any time. We recommend using a more robust solution like Blockweave.
The visual is hosted on a server owned by Everai.
This data can be altered or deleted by Everai at any time.
It would be highly appreciated if Everai hosted this data on Blockweave or IPFS.
It would be appreciated if Everai would create documentation (article or video) that explains how users can retrieve the duo outside the platform.

This audit has been performed by a human and the grade is based on the Utility / Entertainment scheme.
