At the recently concluded SuiOnCampus Port Harcourt Buildathon, held in Nigeria from May 28 to May 31, 2025, one standout project captured the spotlight with its bold vision and outstanding technical execution: Suibiz — a decentralized marketplace and service platform built on the Sui blockchain.
Out of 10 competitive Web3 projects, Suibiz earned a strong 2nd place finish, firmly establishing itself as a rising force in Africa’s growing decentralized technology ecosystem.
Suibiz is reimagining the future of marketplaces by cutting out centralized intermediaries and replacing them with blockchain-powered infrastructure. It’s a borderless, peer-to-peer platform where users — from digital creators to service providers — can: Suibiz is reimagining the future of marketplaces by cutting out centralized intermediaries and replacing them with blockchain-powered infrastructure.

The platform leverages smart contracts, decentralized identity, and on-chain logic to deliver a trustless commerce experience that is built for the real world.
Led by founder and lead developer Ahiakwo John (widely known in tech circles as King Johney), the Suibiz team showcased a highly functional MVP packed with advanced features developed in just a few days.
The key technical highlight of the project are zkLogin with Google OAuth: Simplifies onboarding for non-crypto users, Event-driven product fetching: Uses Sui’s on-chain event model for real-time updates, Custom Move smart contracts: Handle secure transactions, ownership, and user roles, Walrus integration: Decentralized storage of images and metadata, Modern UI/UX: Built with React, TypeScript, and TailwindCSS for sleek, responsive design.
These innovations impressed judges not just for their complexity, but for their practical applicability — a rare standout in a space often dominated by purely experimental ideas.
During final presentations, Suibiz received high praise for: A clear, real-world problem statement, A strong product-market fit, Deep technical execution that matched its ambitious goals.
One judge called it “amazing”, highlighting how the platform’s utility and polish made it a contender far beyond the hackathon setting.
The success of Suibiz at the Suioncampus Buildathon is more than just a win for one team — it’s a signal of the emerging power of Africa’s Web3 builder community. It also underscores the potential of the Sui blockchain to support scalable, meaningful decentralized applications beyond speculation.
As Web3 matures, projects like Suibiz are paving the way for real-world adoption, especially in markets where trust, access, and transparency are still elusive in traditional business models.
Suibiz is just getting started — and if its buildathon performance is any indication, it’s a project worth watching.
Stay tuned as the team continues to build the future of decentralized commerce from Africa to the world.
