Where is the troll visual?
Off blockchain
Where is it stored?
The troll visual is hosted on several computers via IPFS protocol.
What exactly is IPFS?
IPFS is a distributed system for storing and accessing files or assets. This is not a blockchain. You can see more information here.
Does it guarantee the availability of the troll visual?
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.
What if Trollz City website is offline?
You keep your Troll
Here are the elements you can retrieve
- troll visual
- troll name
- other data
Good points 👍
- Trollz City chose to put the troll visual, the troll name 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 Trollz City dies & IPFS survives, you will be able to retrieve this data.
Bad points 👎
- 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.
- It would be appreciated if Trollz City would create documentation (article or video) that explains how users can retrieve the Troll outside the platform.
This audit has been performed by a human and the grade is based on the Computed Art scheme.
