我应该将 IPFS 用于我的可变 NFT 收藏吗？

Question

我不确定将IPFS纳入我的NFT收藏是否是正确的选择. 来自用户的图像数据是可变的，并且不断变化，这使我担心使用IPFS而不是CDN对性能的影响. 此外，我听说更新 IPFS 镜像几乎是不可能的. 如果有任何关于IPFS是否适合我的可变NFT收藏的见解或建议，我将不胜感激.

IPFS and Updating Images IPFS itself does not have built-in updating capabilities, but this does not mean that you cannot build a system for updating images on IPFS. To achieve this, you need to introduce mutability before the IPFS Content Identifier (CID). Heres an example of how you can accomplish this: Create a smart contract where users can update their own Non-Fungible Tokens (NFTs) by submitting a new CID. Although CIDs themselves cannot be changed, this is not a problem. By allowing users to submit new CIDs, you effectively enable updates to the associated content. Advantages over using a Content Delivery Network (CDN): Trust: With a CDN, everyone must trust the provider. However, by implementing the validation logic on a smart contract, anyone can validate the updates on the blockchain. Data Integrity: Users can use the CIDs to verify the hashes of the received data, ensuring its integrity. Cost: If you want to avoid paying gas fees for each update, you can utilize a custom validator or leverage public/private key cryptography, such as IPNS. Performance considerations: While IPFS itself does not inherently have performance limitations, the main implementation (Kubo) has been optimized for torrent-like functionality rather than performance. However, newer alpha implementations show promise in terms of improved speed. The challenge lies in deploying these optimized implementations where they are needed within the network. In summary, by incorporating mutability before the IPFS CID and leveraging smart contracts for validation, you can enable updating images on IPFS while maintaining data integrity and allowing for decentralized verification. Although performance optimizations are still being developed, there is no fundamental reason why IPFS cannot be as fast as other solutions.
