Detailed Project Description (no more than 3-4 sentences)

DUXO is a blockchain-based lottery system, looking to take advantage of the technology's transparent and secure nature. Currently, we are incorporating two types of lottery systems: lotto-based (similar to a Powerball / Mega Millions) and Prize-Linked Saving Accounts, where users are allowed to play based off of the interest within the pot (thus, losing no initial funds). The lotto use case is not only under-represented within the blockchain ecosystem, but the PLSA's would offer potential benefits that would entice various forms of legislation to see potential benefits with a more efficient system.

Describe your tech stack (e.g., protocols, languages, API’s, etc.)

We used Rhombus for our RNG, ShapeShift for our currency conversion, Bloom for identity. We programmed our website (and dashboard) with JS/HTML/CSS, Sketch, & React + Redux.
