Building on Algorand: DeltaHack Hackathon, Recap and Code

Over 700 attendees participated recently at the Algorand Sponsored DeltaHack VI conference. The organizers did a great job and was at a great venue. Some great solutions were provided as many attendees coded all night long. The first place team is Paysy who created a business to consumer transaction app. The second place team is Ez_Transfer who created a consumer to consumer transaction app. Two more entrees had great solutions as well, Team Prim and Team Algopouch. See recap and video team interviews videos below.

First Place: Paysy

Description:

We replace cash, credit, and debit transactions with blockchain technology. However, we overcome the traditional challenges of blockchain by using Algorand’s proof by validation technique. This reduces energy, time, and cost of transaction traditional blockchain down to almost instant time frame just like the current commercial infrastructures with fees.

We provide beautiful and easy to use customer and merchant Android Apps for Paysy. Also, for commercial settings, we provide a java application that can be used in any device by the merchants. Merchants sends a bill to the user, user approves or declines, and the smart contract is fulfilled through a given node.

Team: Prim

Description: Any company or person can request volunteers through the app, and upon successful completion of the volunteer activity, the requester will tip users in-app currency called Leaf, whose transactions are managed by the blockchain technology offered by Algorand. Once users accumulate enough Leaves they can exchange them for incentives like coupons and discount codes for local companies.

Team: Algopouch

Description:

It allows consumer to login to account on the Algorand Blockchain and receive a bill from an app-service. Upon receiving, we display the receipt and an option for the consumer to sign or reject the bill. Upon signing, value is transferred and it is appended to the Algorand Blockchain.
