Oasis Network Bloom Hackathon! Enter Now to Earn $200K in Awards and Engage with The Brightest Minds in Crypto

The Oasis Bloom Hackathon was a $200,000 online hackathon run by the Oasis Network on the Devpost platform from March 10 to May 2, 2022, with support from Jump Crypto, Newman Capital, Neo Global Capital, and Hashed. It challenged developers to build a DeFi 2.0 or play-to-earn gaming DApp on Emerald, the EVM compatible ParaTime. The event closed in May 2022 and drew more than 1,000 project submissions.

This page covers what the competition offered, how entries were judged, who won each award, and where the Oasis developer ecosystem stands today.

What Was the Oasis Network Bloom Hackathon?

Oasis announced the Bloom Hackathon on March 10, 2022 as its biggest hackathon to date. The $200,000 prize pool was funded with backing from Jump Crypto, Newman Capital, Neo Global Capital (NGC), and Hashed. Submissions opened the same day and closed on May 2, 2022 at 5 PM EST, with winners announced on May 31, 2022.

The competition had two focus areas. DeFi 2.0 covered protocols solving known problems from early decentralized finance, such as unlocking the value of staked funds in liquidity pools, reducing impermanent loss, structuring self-repaying loans, and smart contract insurance. GameFi covered play-to-earn games that balance gameplay with financial rewards, including tournament prizes, tradable digital property, and in-game marketplaces.

Every eligible participant also received an exclusive NFT and an MBuddy blockchain identity badge developed with the MetaMirror Gallery from the Auth3 Network. Winners were additionally invited to Oasis Demo Day with access to mentoring and the Oasis Ecosystem Fund.

How the $200,000 Prize Pool Was Split

The awards were organized into two tracks of three prizes each, plus one bonus award. All prizes were paid in ROSE, the native token of the Oasis Network.

• DeFi Mover Awards: Grand Prize by Jump Crypto ($50K), Newman Capital Innovator Award ($25K), Distinguished Award ($15K)
• GameFi Master Awards: Grand Prize ($50K), NGC Innovator Award ($25K), Distinguished Award ($15K)
• Visionary Track bonus: Most Innovative Project ($20K)

Submission Requirements

To qualify, a project had to be built on Oasis Emerald, the EVM compatible ParaTime, and work end to end on Emerald testnet or mainnet. Each team submitted a pitch deck explaining the project, a three-minute demo video, and access to a working application or public GitHub repository shared with the judging team. Entries had to be completed through the official submission form before the final deadline.

Oasis also ran community events during the hackathon window, including team-finding sessions, office hours with core developers, pitch nights, and AMAs covering DeFi 2.0 and P2E gaming trends. These were designed to help participants refine their ideas before the deadline.

Building on Oasis Today

The hackathon-era stack has moved on. According to the current Oasis documentation, Sapphire is now the flagship EVM compatible runtime, featuring encrypted transactions and confidential smart contracts, and it hosts the network’s main development activity. The ecosystem has also added Runtime Offchain Logic (ROFL) for running verifiable offchain computation, and the Oasis Privacy Layer for bringing confidentiality to apps deployed on other chains.

Emerald itself reached end-of-life status as development consolidated on Sapphire, so anyone porting a 2022-era Bloom project should plan a migration rather than a redeploy.
