Thank you so much for sharing your participation in this engagement challenge and for telling us that how STEEM blockchain is a great way for its content creators to provide them a lot of privacy and security as well as you have also describe all the keys that are including in our PDF which we received just after registering our account and login in.

Secondly I agree with you that there is a need to develop more and more security and privacy in this blockchain and for this there could be different things that can implemented as I really like whatever you are saying about confirmation of login by the use of codes sent to our phone number. You have also talk that how all these things would be helpful in the adoption of this platform more and more with the passage of time.

I wish you good luck in this engagement challenge
