TappnEd Team Wins Best UX at EOS Global Hackathon Sydney 2018

The sustainability theme…

Staying true to the sustainability challenge theme we decided to construct the “GreenFix” dApp from scratch (which had little to do with our core software eLearning business TappnEd), but instead focus on a blockchain sustainability solution that would allow general public to nominate and report on sustainable packaging products that were worthy of being rewarded, eg. like the recent Lego sustainable blocks made from sugarcane https://www.businessinsider.com/lego-go-eco-friendly-with-blocks-made-from-sugarcane-2018-8/?r=AU&IR=T.

The Best UX  Award goes to “Greenfix”…

The front-end UX was an easy to use iOS design carefully crafted by our amazing UX expert Derrick Heng.

Nominated sustainable products would receive EOS tokens which could be redeemed or donated to their favourite companies for investment in the adoption of sustainable practices or allocated towards environmental courses company employees could take.

The back-end built on the EOSIO platform, mongoDB and used smart contract generation via C++, was built by the powerful team of Bishal Bhansali and Gopal Gautam, which allowed us to write to the EOS block chain incorporating identity verification, generation of keys and token transfers between user accounts.

The TappnEd team worked tirelessly over the weekend from the Saturday morning until the Sunday afternoon to conceptualize, plan, design, construct, code, prototype, pitch and deliver the GreenFix dApp from scratch. Not much sleep was had by the team who were up until the early hours of Sunday morning smashing away at code and designs in a mad rush to submit by the 1pm Sunday deadline.

The giveaways were truly excellent in high quality “Swag” which only further demonstrated the EOSIO commitment to looking after its community with high quality tools, great events and fantastic prizes. They really didn’t skimp on anything including the event venue (International Convention Centre at Darling Harbour), food, booze, staff and top quality brands in the swag.

The Goodies…

The “swag” was a Moleskine vertical device bag and inside was a H2Go double wall vacuum thermal bottle thermos, Patagonia sweater jacket, Morphie Encore Plus USB battery pack, Moleskine journal, a Classics peaked cap and even a toiletries bag with toothbrush, toothpaste, deodorant, earplugs and eye mask for those hackers who wanted to get a bit of shut-eye in the Nap room! Talk about thinking ahead… EOSIO and AngelHack really put a lot of effort into this event… All in all the prizes would have easily cost $AUD500… and we got it for the cheap developer ticket price of $10 each and a couple of days sleeplessness – bargain!

EOSIO tech, mentors and the event…

In terms of the event it was great to get to meet many of the key people at block.one and EOSIO who helped with business and technical with mentoring. Being able to directly access the extensive human and technical resources of EOSIO in a limited timeframe project was incredibly helpful since we were there to assess the EOSIO tech solution for our eLearning business and to see what these EOS/block.one people were like.

We were amazed at the professionalism, great community spirit, and well organised event which look like being hallmarks of any future events and part of the EOSIO psyche. Nothing was overlooked as being minor by the great event staff from AngelHack lead by the irrepressible Brian Collins who kept the action ticking over and deadlines nailed.

Judges and mentors were all very knowledgeable, helpful and skilled, and were always ready to lend a helping hand and use as a sounding board.


A key part of the event was the $USD 145,000 prizemoney from Block.on’s EOS VC unit who also announced their “Hack. Pitch. Launch” $USD1million seed funding initiative. The program will allow teams from the EOS Global Hackathon events to pitch their DAPPs to EOS VC for the opportunity to receive an investment of US$50,000 to launch their idea. Five teams from each of the four hackathon events will receive seed funding.

Out of the event we managed to take away a much better understanding of the EOSIO platform, their commitment to the community both technically and financially, and the longevity of the EOSIO platform as a viable blockchain solution for developers and business people alike wanting to disrupt the status quo.

Special thanks to…

Thanks to all the judges, mentors, block.one/EOSIO and AngelHack staff for making it a great event. Special thanks to Brodie who was great at helping us with product planning, Jeffrey for listening to our pitch half a dozen times, Julien Heller, Jay Chang, Chris Allnut, John MacMenamin, Bill Woodward and Thom Hallgren..
