Not too familiar with CoralCDN, will check that out. Would say the comparison with IPFS is apt, BitTorrent though requires people to seed on a per file basis right? so versioning for the source of truth etc becomes tough and you need people to care about your data specifically.
IPFS is an alternate solution, but as addresses are not updatable someone somewhere needs to keep track of where the canonical source is. Further, there is no API built in - the data would live at some address, but someone still needs to construct a way to get it without just downloading the whole data dump at once. Perhaps you shard across different files but that has its own issues.
On chain with Ethereum, you can use a smart contract which allows CRUD operations on the data on a per item basis. The latest version of the smart contract data is clear. The API is basically set with the smart contract - infra to get that has already been built with libraries like ethers, and will continue to be maintained since there are other contracts/products out there that rely on the same infra.
