 At the begining neither on-chain, nor off-chain JSON has been following RFC 8785 (canonical JSON) but we reached a point that, due to consistency checks, we need to take hash of both on-chain and off-chain and this forced us to stipulate that both on-chain and off-chain metadata documents need to be converted
 according to RFC 8785 before taking a blake2b-256 hash of them.

-On-chain part has a signature, which has a role to verify that a certain dApp owner made changes. In the initial version, a blake2b-256 signature was needed only for `rootHash` but following discussion, due to security concerns, decision has been made that the signature should attest the whole on-chain canonical JSON except signature field itself (because it would end up in an infinite recursion).

 We made a decision to change the schema so that scripts and releases are no longer required. This could help to get initial registration from dApp developers faster and some stores simply do not require dApps to add their scripts in order to be listed.
 
-### Schema Version
-
-We discussed and analyzed idea of schema version and or even whole CIP version. It turns out that CIP is already versioned by CIP-??? where ??? is version number. During this CIP being in `PROPOSED` state we reserve our right to make small changes to the schema / document, after CIP becomes active, it will require a new CIP. This is the current process, which other CIPs are also following.
-
 ### Tags
 
 We briefly discussed tags and we will likely introduce tags in the future. An array of tags to help stores / dApp developers categories where their dApp should show. This will complement `categories` field.

 - **`integrity`**: The dApp's off-chain metadata should match the metadata **anchored** on-chain.
 - **`trust`**: The dApp's certificate should be signed by a trusted entity. It's up to the store/auditor to decide which entities are trusted and they should maintain and publish their own list of trusted entities. Although this entities might be well known, it's not the responsibility of this CIP to maintain this list. These entities could be directly associated with developer/publisher or not.

 *`rootHash`*: The blake2b-256 hash of the entire offchain metadata tree object. This hash is used by clients to verify the integrity of the metadata tree object. When reading a metadata tree object, the client should calculate the hash of the object and compare it with the `rootHash` property. If the two hashes don't match, the client should discard the object. The metadata tree object is a JSON object that contains the dApp's metadata. The metadata tree object is described in the next section. Please note that off-chain JSON must be converted into RFC 8765 canonical form before taking the hash!
