What is AFA score?
What the AFA score takes into account.
Each platform that mints NFTs chose its own method to attach an asset to the token. The problem is that these methods don’t offer the same level of decentralization and persistence. That’s why we built the AFA score.
The AFA score evaluates the decentralization and the persistence of NFT assets.
Here are the most used storage methods:
😎: data gain great decentralization and great persistence.
😢 : the blockchain usually asks for gas to write data. It could be expensive.
Stored on another blockchain than the NFT: some blockchains have been optimized for heavy assets like video. Blockweave is an example.
😎 : cheaper storage and great data decentralization & persistence.
😢 : the fact that NFT data are stored in different places (2 blockchains) doubles the risk of losing data.
😎 : the decentralization and the data persistence are greater than storing it on a server.
😢 : it does not guarantee data decentralization & persistence. Somebody needs to “pin” the data to keep it available. Most of the case the platform does it for you. Also, the data can be stored on a unique node.
😎 : the data is stored on several computer nodes.
😢 : the owner of the hosting has total control over the data. It can be altered or deleted at any moment.
😎 : nothing.
😢 : the owner of the hosting has total control over the data. It can be altered or deleted at any moment. Also, the data is stored on a unique server.
So we classified these methods by data persistence level & data decentralization level:
The AFA score is based on these two scales.
On traditional blockchains like Ethereum or Binance Smart Chain, some NFT platforms let artists upload their own creations (e.g. Rarible). To keep its value, the asset must not be reduced or altered. So the platform doesn’t have control over the asset size. The money needed to store a large-sized asset on those blockchains can reach millions of dollars 😰.
👉 We are aware of this difficulty. So we consider that the best storing method for uploaded content is a cheaper media-storing oriented blockchain like Blockweave.
