We put out a challenge to the Blockstack Community to create an Encrypted Token Portfolio app on Blockstack to give users ultimate privacy and control when tracking their token holdings.
We requested that participating developers to allow you the user to (1) single sign-in with an identity you own (no need for third parties like Google or Facebook), and (2) gives you the privacy to manage your token holdings on your own encrypted cloud storage provider (visible only to you).
Apps like the ones described above are what we call single-player decentralized apps, in that the data lives with you and can only be accessed by you.
The logical next step for our community is to build multi-player decentralized apps, where each user can own and control access to their own data, but also share it with your friends without the need for a third party. That next bounty has been announced here.
All completed Token Portfolio Management apps are in public alpha and are listed in alphabetical order below. Note that they are all in alpha and were created in a short period of time, so you may expect a hiccup or two. Download Blockstack at blockstack.org/install to use them.
