Chainlink VRF v2正式在主网上线，为NFT和游戏dApp提供可扩展、可灵活配置且gas费更低的链上随机数

Chainlink's Verifiable Random Function (VRF) has become a standard for secure and transparent random number generation in smart contracts and off-chain systems, with its latest version, VRF v2, offering enhanced features for developers. Since its inception, Chainlink VRF has supported over 2,300 smart contracts across multiple blockchains, including Ethereum, Polygon, and Binance Smart Chain, by providing tamper-proof on-chain randomness. VRF v2 introduces improvements such as cost-effective subscription management, flexible gas fee settings, customizable security parameters, and the ability to request multiple random numbers in a single transaction. This upgrade reduces transaction costs by up to 60% and enhances the efficiency and flexibility of decentralized applications (dApps). By simplifying processes and expanding its utility, VRF v2 supports a wide range of applications, from fair NFT minting and airdrops to lottery drawings and gameplay mechanics, ensuring fairness and security in blockchain interactions. The launch of VRF v2 signifies a step towards more autonomous and customizable decentralized services, with plans to deploy on additional blockchain networks and integrate with other Chainlink services for diverse use cases.
