Decentralized applications can benefit from verifiable randomness generation in multiple ways. For instance, gambling protocols and DeFi platforms are always closely scrutinized by their users and magnets for hackers looking to exploit some kind of vulnerability. While solutions do exist, such as generating a random value through an API, these methods are vulnerable to known abuses such as rerolling or rewrite attacks.
With the debut of Oraichain VRF 2.0 on Avalanche, dApps running on the network can benefit from publicly verifiable random number generation that's 100% tamper-proof and transparent, verifiable via a group signature verification process.
Whenever an Avalanche dApp makes a request for randomness with Oraichain VRF, the request will be emitted as an event from the Oraichain Mainnet via the Avalanche-Oraichain bridge. Oraichain VRF then binds a pairing-based threshold cryptosystem library to its smart contract to verify validator's signatures, creating a group signature on-chain. It then generates a publicly verifiable random value that's submitted back through the cross-chain bridge to the VRF contract and, from there, to the Avalanche dApp.
Oraichain VRF makes it possible for developers with only a limited knowledge of smart...
