Mousebelt Kafka to HCS Challenge

The winning team - Oxiles - built an event listener that bridges Hedera with other blockchains and backend microservices, including Apache Kafka.

Exiles is a unique infrastructure project that makes it incredibly easy to bridge Hedera to other popular ecosystems, including Apache Kafka, or the Ethereum Blockchain. Through the usage of familiar components like Docker Containers, anyone can bridge their data to the Hedera Consensus Service.

Prize - Support from the Mousebelt Accelerator Program

MoonPay Fiat to HBAR Challenge

The winning project - HumanKind - turns acts of kindness into currency for you and the causes you care about.

This project was able to implement the best use of historical and real-time data from the DragonGlass Mirror Node and network explorer. By creating HCS subscription events for all of the acts of “human kindness” they are able to build a transparent history of giving. By leveraging the MoonPay fiat to HBAR widget, they can easily enable anyone to access the fast, and low fee cryptocurrency that powers the Hedera network.

Prize - $2,500 in HBAR, and free access to the MoonPay fiat to HBAR payment widget

Hedera Social Good Challenge

The winning project - Ocean Plastics Collecting and Recycling - Brings corporations, governments, and citizens together to promote ocean plastic collection and recycling and save the depleting marine life.

This project demonstrated a wide range of functionality - creating a multi-sided, crypto-incentivized ecosystem, to tackle one of the most important projects in the world. How can we reduce our plastic waste and encourage recycling? It’s clear that ambitious projects utilizing new technology are going to be required for the drastic changes needed in to overcome such large challenges, and this project showcased a number of new ideas.

Prize - A 3D printer per team member

Hedera Consensus Service - Third Place

The winning project - 3IEIO - helps employees & employers create verified career identities from meaningful recognitions and engagements using the Hedera DID SDK.

This team showed that they have the ability to create new methods of HR engagement, enabling employee reputation, and grant management to be carried across employers. By using verifiable credentials, 3IEIO creates an immutable trail of recognition, that can be cryptographically proven at any point in the future.

Prize - $5,000 in HBAR

Hedera Consensus Service - Second Place

The second place overall project - Public Pest Network - built a secure, decentralized network that makes it possible for researchers, farmers, and the public to submit, view, and analyze pest data.

Distributed public ledgers can be thought of as a public good, and there’s immense value in sharing public data sets utilizing their transparency. The Public Pest Network demonstrates this wonderfully by creating data standards for researchers and universities to host, store, and maintain their own datasets, allowing them to utilize whatever existing toolkits for analytics or other tools that may be required in their day-to-day lives.

Prize - $10,000 in HBAR

Hedera Consensus Service - First Place

The winning project for the Hedera20 Hackathon was - Oxiles - who built an event listener that bridges Hedera with other blockchains and backend microservices.

This solution is unique, enabling Hedera Mirror Nodes to receive, and emit, event history between other centralized and decentralized infrastructure. Interoperability between not only existing, traditional infrastructure such as Apache Kafka and Apache Pulsar, but also between other distributed ledgers like Ethereum, is a large problem to solve. But the Oxiles team showcased a great solution, skillset, and ambition to tackle this challenge, and built a great project throughout this six-week event.

Prize - $20,000 in HBAR
