B³
Build. Block. Break.
What is B³?
B³ (B-Cube) is a 30-hour blockchain hackathon by VinnovateIT, one of Yantra’26’s flagship events, where Web2 ideas are reimagined and built on-chain.
Why Blockchain?
Most of the internet today runs on Web2, apps and platforms controlled by companies that manage our data, content, and experiences. It’s convenient, but do we really have true ownership or control?
Web3 changes the game. Powered by blockchain, it puts power back in the hands of users with decentralized, secure, and transparent systems where you own your identity and digital assets.
It’s the shift from platforms controlling everything to people building and owning the internet themselves, a smarter, fairer, and more open web for everyone.
What We’re About
The builders of MessIT are back with another hackathon. VinnovateIT is where curiosity turns into creation. A community of builders and innovators exploring technology beyond classrooms, through hands-on learning and real problem solving. We don’t just learn tech, we build with it. Because real innovation begins when ideas meet execution.
