Where are the attributes?
Off blockchain
Where is it stored?
The attributes are 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 attributes?
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 Heroes Of Evermore website is offline?
You keep your hero
Here are the elements you can retrieve
- attributes
- visual
- other data
Good points 👍
- Heroes Of Evermore chose to put the attributes, the visual 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 Heroes Of Evermore 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 Heroes Of Evermore would create documentation (article or video) that explains how users can retrieve the hero outside the platform.
