About the Hackathon
For this hackathon, we’re thrilled to introduce you to opBNB and Greenfield, two cutting-edge blockchain platforms that offer endless possibilities for developers and entrepreneurs.
BNB Greenfield provides decentralized storage infrastructure within the broader BNB Chain ecosystem. The idea is to help users and dApps to create, store, and exchange data with full ownership, and form a new data economy.
The opBNB network is the Layer 2 scaling solution for the BNB Smart Chain, powered by the bedrock version of Optimism OP Stack. It allows users to deposit and withdraw funds, use smart contracts, and view network data with high throughput and low fees, all while scaling beyond the constraints of the BNB Smart Chain.
Hackathon Requirements
We encourage you to develop in line with our Wishlist, which includes exciting tracks in both Greenfield and opBNB. Each track offers exciting challenges and opportunities for innovation. You can view the details list at the bottom of this announcement.
Key Dates
Rewards
We’re offering fantastic rewards for your hard work and innovation:
- 1st Prize: $15k
- 2nd Prize: $10k
- 3rd Prize: $5k
- Common Prize Pool: $30,000, where all qualified submitters will share the prize pool.
Get ready for incredible rewards that match your hard work and innovation!
The Rules of the Competition
Please read and follow the competition rules to ensure a fair and enjoyable experience for all participants. These rules cover eligibility, participation requests, and conduct during the event.
Submission Requirements
- Work must be deployed on or connected to GF/opBNB in some way.
- Work that is open source and free for others to use.
- Shared artifacts (GitHub, planning documents, and a short video).

Projects will be evaluated based on 1) functional prototype highlighting a solution, 2) creativity, 3) readiness of the dApp and 4) usability.
The Spirit of the Competition
Remember, hackathons are about learning, collaborating, and having fun. While some aim to win, most are here to explore new ideas. Keep the hacker spirit alive by working with other teams, mentoring newcomers, and enjoying yourself.
Join us in Istanbul for the BNB Chain Hackathon Istanbul, where innovation knows no bounds, and the future of blockchain technology is in your hands. Together, let’s push the boundaries of what’s possible and shape the future of finance and data management.

Competition Rules – Further details
1. Eligibility:
Team Size:Teams may have a maximum of 5 hackers.
2. Participants Requests:
Hackers who have been accepted to compete on a team must not be event staff, volunteers, mentors, judges, sponsors, or anyone else with special access to the competition.
Participants, including organizers, volunteers, and sponsors, are available to offer teams guidance and assistance.
4.The hackathon is the only place where work can be done on a project.
5. Groups are allowed to implement a strategy they developed in advance of the competition.
6. Teams have the option of focusing on already completed ideas. There is no requirement for “innovation” in hacks. Anyone is welcome to contribute to a shared idea, and their work will be evaluated based on how well it is “hacked.” (It’s unusual to come across something wholly novel these days, and teams often aren’t aware if they’re recycling a concept.)
7. Groups are free to include third-party resources, such as code repositories, into their work. It is against the spirit of the guidelines to work on a project ahead of time and open-source it with the sole intention of using the code during the event.
8. It is acceptable to include additional functionality into ongoing projects. Winners will be determined solely based on the value of any new features or functionalities introduced during the hackathon.
9. When the clock runs out, teams must cease their hacking activities. After the allotted time has passed, however, teams are free to debug and make minor adjustments to their applications. e.g. It’s acceptable to fix a bug that prevents you from demonstrating your hack if doing so involves adding only a few lines of code. You are not permitted to make any major alterations or introduce any new functionality.
10. Teams can be disqualified from the competition at the organizers’ discretion. Reasons might include but are not limited to breaking the Competition Rules, breaking the Code of Conduct, or other unsporting behaviour.
