[DIP Proposal] Steem mobile wallet and authentication app

Greetings!

Following the Steemit DIP initiative announced by @steemitblog, it is time to develop the infrastructure and tools essential to Steemit and its community users.

Proposal Background

It has been 6 years since the Genesis block of the Steem blockchain was created. Steemit is still functioning today as the 1st blockchain-based social media platform and the oldest PoC.

Numerous new social media projects have been launched since the advent of Steemit, but no challenger has emerged beyond Steemit. Nevertheless, the number of new onboarding users of Steemit is gradually decreasing. Why?

• Is it because the rewards for the effort put into creating the content aren't that great?
• Is it because the price of STEEM or SBD keeps dropping?
• Is it because of the low APR compared to many DeFi projects?

We think the biggest reason is the terrible UX on mobile devices.

Most people today spend a large part of their day looking at their phone. They google or watch YouTube on their mobile phones, communicate with SNS such as KakaoTalk, WeChat, Telegram, and Twitter, and play mobile games.

After all, how mobile-friendly infrastructure is in place is a key factor in the growth and prosperity of social media platforms and communities.

We desperately want the Steem blockchain and Steemit to become more mobile-friendly. A Steem account is not just a social media account, it is also a wallet that holds valuable digital assets. So security is more important than any other social media, and making it technically perfect takes a lot of work. (Of course, there are regulatory issues that are not yet crypto-friendly)

Nevertheless, we would like to solve this problem with the Steem DIP from the @steemitblog team. Below we would like to propose SteemStation, an authentication and wallet application that allows you to use Steemit more conveniently and safely on your mobile device.

Proposal Overview

• Name : SteemStation
• Brief Description : The SteemStation is mobile wallet and authentication service for Steem. This provide a way for any applications to easily authenticate users without asking them to provide any password or private key. Users can easily and securely log in to Steemit.com and various Steem-based apps, regardless of location or device they use (desktop or mobile browser).

Future Plans

• Development will begin as soon as this grant proposal is approved.
• The development progress is transparently disclosed through monthly and quarterly reports and github.

Tbh there is a cheaper way to create a Steem mobile wallet by forking the Hive keychain. However, using an in-app browser like Hive keychain doesn't do much to improve UX. All users should have the convenience of using Steemit.com anytime, anywhere, and we believe it is right to build ours intact through Steem DIP.

If various apps are developed based on Steam in the future, OUR OWN APPS created from zero base, such as Steam Station, will play an essential role in integrating them.
