# Re{define} Hackathon Re{define} Hackathon is a hackathon focused on two core narratives: Privacy and Bitcoin on Starknet. We're building tools and applications that combine privacy-preserving technology with Bitcoin integration. From encrypted compute to atomic swaps, from zero-knowledge proofs to trust-minimized bridges, we want to see what builders create when they focus on what matters. # Why now? - Privacy is the institutional priority for 2026 - Starknet is the Bitcoin DeFi Layer with quantum-safe ZK tech - Starknet is doubling down on privacy and Bitcoin infrastructure, this is the moment to build # Timeline - January 19: Registration opens - February 1: Hackathon starts - February 28: Hackathon ends - March 1-14: Judging period - March 14: Winners announced # Prize Tracks ### Cash Prizes: $21,500 - 🔒 Privacy: Build privacy-preserving applications using STARKs, zero-knowledge proofs, and confidential transactions - ₿ Bitcoin: Create BTC-native DeFi leveraging Starknet's security, bridges, atomic swaps, OP_CAT apps - 🚀 Wildcard: Build any innovative product on Starknet, gaming, social, payments.
