 The client MAY break large blobs into any number or size of chunks. although its recommended to use the size `1Mb` or `4Mb` for small and large chunks

 Clients MUST create a merkle tree using the chunk hashes as the leaf nodes
 
-### Merkle tree encoding
+### Publishing
 
-The merkle tree MUST be in the format of `[<root hash (Uint8)>, <left>, <right>]` and be encoded using [`CBOR`](https://cbor.io/)
+Clients should publish a `2001` kind event after chunking the file in order to store the list of chunks
 
+The events `content` MUST be set to am ordered JSON array of the chunks sha256 hashes. e.g.
 
-Example:
+```json

-### Merkle tree storage
+The `2001` event MAY include additional metadata tags to help other clients know the filename, mime type or servers to download from
-
-Clients MAY choose to store the merkle tree on nostr relays using the `2001` kind event
-
-The event MUST include an `x` tag with the merkle root to the `2001` event
-
-The event MAY include additional metadata tags to help other clients know the filename, mime type or servers to download from
 
 Metadata tags:
   - `name` Filename
   - `summary` A short summary of the file
   - `m` Mime type of file
   - `size` Total size in bytes of the file
-  - `x` Merkle root
   - `server` (multiple) Recommended servers to download chunks from
