Need for Bits

Need for Bits is a fully onchain racing game on Starknet that fuses speed, skill, and ownership. Every drift, boost, and victory is recorded onchain, provably fair, transparent, and unstoppable.

Inspiration

Need for Bits was inspired by the flaws in Web2 gaming — from creators earning pennies locked behind KYC walls to players losing progress when servers shut down. The frustration of digital rights violations and corporate control sparked our mission to build a game where players truly own their achievements and assets. Collect Bitcoins along the way and grow your chain to make it the longest while spending it to reap the rewards and upgrade your vehicle.

What it does

It’s a fully on-chain racing game built on Starknet, merging real-time gameplay with blockchain-backed ownership. Every race, move, and reward is verifiable on-chain, ensuring fairness, persistence, and true player control without requiring blockchain knowledge:contentReference.

How I built it

We built the game using Starknet as the blockchain layer, Cartridge for wallet abstraction and onboarding, and an on-chain provable engine that records game logic directly to the blockchain. Merkle inclusion proofs were implemented to create inclusivity for NFT holders and enable verifiable digital assets:contentReference.

Challenges I ran into

Creating a non-turn-based, real-time fully on-chain game was a major challenge. We had to overcome the limitations of blockchain throughput and transaction latency while preserving the racing experience. Balancing scalability, gas efficiency, and deterministic logic required heavy optimization and creative engineering:contentReference.

Accomplishments that I'm proud of

We successfully built a fully on-chain real-time racing system with zero blockchain knowledge required for users. The project also integrates NFT-based access and tournaments, showcasing how blockchain can power transparent, inclusive, and scalable gaming ecosystems.

What I learned

We learned that on-chain gaming is about more than decentralization — it’s about building trust and permanence into player experiences. It taught us how to merge high-speed gameplay with cryptographic proofs and design for both gamers and developers.

What's next for Need for Bits

Next, we’re launching regional tournaments and expanding partnerships across Starknet communities. Our roadmap includes integrating social leaderboards, expanding NFT ecosystems, and scaling to mobile platforms to make on-chain racing accessible to everyone.
