Hedera 20 — the first virtual Hedera Hackathon

Last February Hedera Hashgraph launched low-cost Hedera Consensus Service in developer preview, as we are still in early days of developers and entrepreneurs exploring the possibilities of this exciting new technology, Hedera Hashgraph announced their first virtual Hedera hackathon, Hedera20.

In this blog we are going to explore in detail, the challenges you can solve as part of the hackathon, prizes which are up for grabs as well as benefits of building your project on Hedera.

What is Hedera Hashgraph

The Hedera Hashgraph network is an innovative distributed ledger platform that aims to resolve the factors that constrain adoption of public DLT by the mainstream. The platform is built on the hashgraph distributed consensus algorithm, invented by Dr. Leemon Baird. Unlike other blockchain protocols, Hedera Hashgraph is speedy and efficient with lower fees because less energy is used. The hashgraph consensus algorithm provides near-perfect efficiency in bandwidth usage and consequently can process hundreds of thousands of transactions per second in a single shard. Consensus latency is measured in seconds, not minutes or hours. Hashgraph achieves the gold standard for security in the field of distributed consensus: asynchronous Byzantine Fault Tolerance (aBFT). Other platforms that use coordinators, leaders, or communication timeouts to improve performance tend to be vulnerable to Distributed Denial of Service (DDoS) attacks. Hashgraph is resilient to these types of attacks against the consensus algorithm because there is no such leader.

What do you have to do to win the prizes?

Starting from 2nd of April and until 11th of June you’ll be able to sign up as a team or form a new team on hackathon digital platform, develop a solution which takes advantage of the most unique qualities of Hedera including: fair ordering, proving an action occurred, or providing real-time audit logs and compete for the chance to win over $35,000 worth of prizes including HBARs, acceptance into the MouseBelt accelerator program, and more.

The main prizes are going to be distributed in the following way:

1st place — will receive a Grand Prize worth $20,000 USD worth of HBAR

2nd place — will receive $10,000 USD worth of HBAR

3rd place — will receive $5,000 USD worth of HBAR

While you’re welcome to use any Hedera network service, in order to maximize your chances of winning one of the main prizes you are recommended to build a solution that takes advantage of some or all of the following Hedera Consensus Service core benefits:

· Fair Ordering — In use cases that require strong ordering guarantees like user matching, bidding, or time bound actions use the Consensus Service for transparently connecting the dots.

· Proof of Action — A decentralized set of computers can tell you an event occurred, who agreed upon it, and when it happened. Ideal for an open API or managing processes that require a central issuing authority, be it a proof of employment or that you uploaded a file.

· Audit Logs — Ongoing tracking of key events can provide irrefutable audit logs between parties. Beneficial for knowing when a file was accessed, an ad viewed, or a song played.

There is also set of additional challenges in which you can take part and win prizes outside of main competition:

· Social Good Challenge by Hedera Hashgraph — Apply your skills for social good! Solve a key issue around topics like charitable giving, healthcare, climate change, or your own personal passion to help improve society. Each member of the winning team will receive a 3D Printer!

· DragonGlass Challenge by DragonGlass — The winning project team will receive $5,000 and 2 months of free Tech Help and Support from the DragonGlass team to help them prepare for production. DragonGlass was created to make distributed application development simple and fast by providing developers with key tools that they would need, namely the complete suite of Hedera Data APIs and realtime Subscription Service. The possibilities for how to implement these tools are immense, and for DragonGlass challenge, you would have to build an application that highlights either of these two toolsets. The winner of the challenge will be the most innovative dApp that highlights the use of DragonGlass APIs or the DragonGlass Subscription Service, so developers participating in any of Hedera’s other challenges can qualify as long as they highlight DragonGlass tools in their solution.

· Hashing Systems Challenge by Hashing Systems — Hashing Systems will be awarding $3,000 worth of hbar cryptocurrency for the top 4 decentralized applications using the hash-sdk npm package and/or the Composer Browser Extension.

· Armanino Challenge by Armanino — To qualify for this challenge, build a robust, open source, signing service for Hedera wallets enabling users to prove account/wallet ownership to counterparties, management, and auditors. Winners will receive pairs of Bose QuietComfort II Headphones.

· Accelerator Challenge by MouseBelt — Create a package to ingest a message from Apache Kafka, and based on some filtering content, push it to Hedera Consensus Service. It should include a way to browse and verify the message in a clean/simple UI. This service could be used by exchanges or other businesses to verify some aspect of their business is real & auditable, directly from internal tools. The winner of the challenge will have the chance to work with MouseBelt dedicated team of specialists and professionals for at least a month that could potentially be extended, taking this idea and turning it into reality. MouseBelt’s goal is to work with the winning team, providing technical guidance and business strategy. MouseBelt core objectives may include product-market fit, go to market strategy and development of solutions leading to a successful and sustainable business.

How to take part in the Hackathon

From 1st of April onwards, you can register to take part in the hackathon on the BeMyApp platform via the following link. If you are signing up on your own, BeMyApp will work with you to find a team which you can join. If you sign up as a team, you can sign up together and work on the platform through separate user accounts.

The hackathon opens on May 1st, and will be going on for 6 weeks, during this time you will get mentorship, healthcare and industry advice, as well as technical support and resources for your project from Hedera and others. As part of the program you will have webinars and online support to make sure that by week six, you’ll have a proof of concept page to pitch to the panel to be considered as a finalist.

After the submission deadline, qualifying teams are going to be selected and will get the chance to pitch in front of the judges. The pitch session will be livestreamed to the Hedera Hashgraph global community, and winner’s selection process will be conducted in real time. The top winners will receive thousands in HBar as well as other prizes.
