Oraichain Launches First-Ever Verifiable Random Function on Avalanche

Oraichain, an AI-powered oracle and blockchain ecosystem, has unveiled the launch of its Verifiable Random Function (VRF) on the Avalanche network.

Through this, Avalanche ecosystem developers can reap the benefits of a fully decentralized, publicly verifiable random number generator that’s tamper-proof and verifiable through a group signature verification process.

That said, Oraichain CEO Chung Dao comments on this new milestone for the company:

With the introduction of Oraichain VRF 2.0, for the first time ever, Dapps running on Avalanche are now provided with a fully on-chain VRF service that are publicly verifiable and impervious from known abuses like rewrite attacks or rerolling.

Furthermore, when an Avalanche DApp sends a request for randomness via the Oraichain VRF, the said request will be transmitted as an event from the Oraichain Mainnet through the Avalanche-Oraichain bridge.

Consequently, Oraichain VRF integrates a pairing-based threshold cryptosystem library to its smart contract to confirm the validator’s signatures. This then results in creating a group signature on-chain and generates a publicly verifiable random value that is given back through the cross-chain bridge to the VRF contract. From here, it finally gets directed to the Avalanche DApp.

With Oraichain VRF, developers who are not well-versed in smart contracts can effortlessly create and verify VRF values. Since each signature contribution from the VRF executors needs to be verified on-chain with Oraichain before it’s stored, they can be confirmed through an easy query to the VRF smart contract.

Meanwhile, with regards to publicly verifiable random value generation, it is available only as a plug-and-play service to Avalanche DApp developers and can be used when needed directly with Oraichain.

Moreover, Avalanche developers can seamlessly combine publicly verifiable randomness into all types of DeFi and NFT applications, paving the way for transparency and fairness to NFT and token airdrops and several use cases.
