We're thrilled to introduce the world's first zkRaffle—a pioneering innovation that combines the mechanics of an onchain raffle with zero-knowledge technology. This convergence marks a milestone for the decentralized ecosystem, delivering provable fairness, and paving the way for more verifiable quests.
This breakthrough was made possible through our collaboration with Succinct, the leading project in zero-knowledge proof technology, using their zkVM SP1. Together, we're laying the foundation for more secure, trustless applications that empower both projects and users, fostering a truly trustless web3 environment.
Shaping the Next Era of Raffles
zkRaffles eliminates the reliance on centralized authorities by using smart contracts and zero-knowledge proofs to ensure fair, tamper-proof outcomes. With full transparency on the blockchain, every step is auditable, reinforcing both fairness and security. Built on decentralized infrastructure, zkRaffles eliminate single points of failure, offering a more secure and reliable solution.
Here are the key features of zkRaffle on Galxe:
Verifiable Randomness: Powered by our own Drand oracle, an open-source public good project that brings Drand data onchain. This allows anyone to access both current and historical Drand data.
Zero-Knowledge Proofs: Uses SP1 zkVM to generate a proof of the raffle’s execution, ensuring fairness.
Merkle Tree Verification: Enables winners to prove their status efficiently via Merkle proofs.
Cross-Chain Compatibility: Supports reward distribution across multiple blockchains.
300K G: Unlock the Future of zkRaffle

To celebrate the launch of zkRaffle, we’re teaming up with Succinct to launch the zkRaffle Quest to highlight the platform’s use of ZK technology for onchain verifiable fairness in raffles with a prize pool of 300,000 G tokens.
This quest will guide explorers through the intricacies of zero-knowledge technology, providing a hands-on experience with its tamper-proof capabilities. Participants will learn how ZK technology ensures verifiable fairness while immersing themselves in a secure, transparent raffle process.
