What does a Merkle Tree bring here? (honest question) I mean: for content-based addressing of chunks (and hence deduplication of these chunks), a regular tree works too if I'm not mistaken (I may be wrong but I literally wrote a "deduper" splitting files into chunks and using content-based addressing to dedupe the chunks: but I just used a dumb tree). Is the Merkle true used because it brings something else than deduplication, like chunks integrity verification or something like that?
