+## Preamble

+    Idea: #027-username-ens-subdomain
+    Title: Username ENS Subdomain Registrar
+    Status: Draft
+    Created: 2017-11-20
+

+- UX (Status): 
+
+## Product Overview
+
+A bad experience in most cryptosystems, aswell Status, is the requirement of typing or scanning the public keys and addresses to interact with other users in the network.
+ENS disrupt centralized DNS: like DNS resolves into IPs, ENS resolve into ethereum addresses (and more) trustlessly.
+Status would introduce a option for users registering a human readable contact username and its URI would be used in place of QR codes / private keys.
+A small fee is required, so users are buying the subdomain, and therefore could be exchanged with other users, this network effect is ignored by this idea.
+
+### Product Description
+
+Users would be able to:
+- buy a subdomain from one of the ENS domains owned by Status.
+- find users by using the configured ENS Resolver for EMS address (subdomain.domain.eth)
+- search/suggest domain for a username.
+- send funds by typing their ENS address.
+
+Subdomain owners would be able to:
+- change the owner of the subdomain
+- change the resolver of the subdomain
+
+Democracy (or authority) would be able to:
+- add new domains available with its own price
+- change domains price
+- change owner of domain (required for update of subdomian registry)
+
+### Minimum Viable Product
+Goal Date: 2018-05-10
+Description: 
+
+- Users can register (FIFS) an available username in Status's ENS subdomain
+- Users can add friends by entering an ENS address
+- Basic UI for call include a domain
+
+## Success Metrics
+Most users opt-in to register their username and use username subdomain to find their friends.
