+- <sup>**[1]**</sup> There's no Identity Wallet applications that implement `erc725` yet.
+- <sup>**[2]**</sup> uPort claims & proofs is a simple key-value storage. Verifiable Claims can be stored within as values of that storage.
+- <sup>**[3]**</sup> `erc725` is studying the possibility to embrace Verifiable Claims but as of now, the `data` and `uri` of claims are agnostic.
+- <sup>**[4]**</sup> uPort is working on a new DID method, called `ethr`, that will support delegates: https://github.com/uport-project/ethr-did-resolver.
+- <sup>**[5]**</sup> Key rotation & revocation is possible via a (optional) Proxy Contract
+- <sup>**[6]**</sup> The identity creation is free but one must (optionally) pay ~0.001096 bitcoins to have a username
+- <sup>**[7]**</sup> OriginProtocol developed a "playground" to demonstrate the potential of the DID method, but it's not production ready nor enables users to authenticate to dApps: https://erc725.originprotocol.com
