Lio was a cryptocurrency portfolio app we developed for a competition organized by Blockstack (now Stacks) several years ago. We utilized Vue.js and TypeScript to build the frontend. The competition's goal was to utilize and highlight Blockstack's technology, which enabled users to control their data when using web applications.

The unique aspect of this technology involved users logging in with their Blockstack account, linked to a self-custody Bitcoin address. When accessing an app, users selected a directory on their computer containing the encrypted data for their Blockstack apps. This data was then uploaded and processed via the Blockstack JavaScript library each time the app was used, offering a privacy-focused alternative to the traditional model of user data being stored on an app's backend.

Following the competition, Lio was featured on Blockstack's website for several months.
