Attracting nearly 200 participants and 13 high-quality submissions, the online hackathon produced a range of smart contract applications spanning finance, law, identity, trade, supply chain, charity, healthcare and gaming.

US$10,000 First Place: Cirrus Swap

Tyler Pena took the first-place prize of US$10,000 for his Cirrus Swap decentralised exchange application which allows users to hold their own tokens and settle trades on Stratis’ Cirrus Sidechain.

Cirrus Swap is a set of four contracts – BuyOrder, SellOrder, Orders, and JsonConfig – working together with a User Interface (UI) to create a clean user experience for trading SRC-20 for CRS tokens. It means that users only need to open the Cirrus Swap UI and Cirrus Core wallet to immediately begin trading.

As more SRC-20 tokens join the Cirrus Sidechain, for example MEDI, the application will make it easier for users to exchange tokens on chain in a decentralised manner, as opposed to utilising traditional methods like cryptocurrency exchanges. This added functionality will improve liquidity on the Cirrus Sidechain and help the token economy to thrive.

Cirrus Swap demonstrated a proven use case that provides millions in daily value right now. Cirrus Swap’s UI not only works but is aesthetic and intuitive. The contract code is clean, well-tested, and integrates with existing Cirrus contract standards. The project has even put effort into branding – Cirrus Swap could feasibly be a real product with a full team behind it.

US$5,000 Second Place: Wheelgame

This gambling web application was designed by Sergey Ankarenko. Based on a standard multi-player bidding game, players log in with a decentralised, arbitrary private key to make it impossible for participants to cheat or gain an illegal advantage. The ultimate vision behind the application is that it could be extended across the gaming sector, including online casinos.

US$3,000 Third Place: Stratis Signature

This web application for digital signatures was created by Divyang Desai. It allows multiple users to securely create, sign and verify documents. This enhances integrity and transparency, making it perfect for use by enterprises in law, invoicing, resource management, operations and finance.

The judges also commended other notable submissions including the Sale Deed Registry, Passport Agency Office (passport application/renewal), and TrustEvent (decentralised event ticketing system).

Chris Trew, CEO and Founder of Stratis, said: “We would like to congratulate all of the entries in our Smart Contracts Challenge, especially the top three winners. The number of high-quality submissions was extremely impressive and highlights the functionality possible on the Stratis Platform as well as the enterprise and government applications that can be built using Stratis Smart Contracts. “It was also encouraging to see just how many new developers submitted entries. We pride ourselves on making blockchain easy and this was evidence of how we can encourage smart contract adoption by attracting developers already familiar with C# programming. “We will now look to take forward the best use-cases in order to add utility to the STRAT token and boost our credentials for enterprise adoption. Following the success of this hackathon, we hope that there will be many more in the future.”

The hackathon ran from 1 November to 16 December 2019 and was open to submissions from individuals and teams from around the globe. Developing on the Stratis Platform, participants were encouraged to build smart contract applications that are useful, easy to use, innovative and impactful.

The judging panel consisted of sector experts, including developers, blockchain gurus and Microsoft MVPs judged the submissions on their utility, usability, creativity, functionality, and design and documentation.
