XANALIA and ChainLink
XANALIA — NFT Marketplace integrates Chainlink VRF to Enable Completely Random NFT Drops in its Marketplace
We’re excited to announce that XANALIA — a decentralized marketplace for NFT Game / Metaverse ready NFTs — has integrated Chainlink VRF on Polygon mainnet to enable the minting of completely random NFTs without possible tampering or bias. This will bring an exciting gamified element of chance and unpredictability to the process of collecting NFTs.
XANALIA is a decentralized multi-chain NFT marketplace for metaverse generation. It empowers global known animation / games and any type of digital art creators to turn their assets into digital copyrighted tradable assets , and provide utility to make them usable in NFT games and XANALIA’s own NFT metaverse called “XANA”. XANALIA is designed to be fast in terms of its operations and cheap in terms of fee/cost per operation at the protocol level and inline operations.
One of the exciting features launched on the XANALIA marketplace is a blindbox, which mints NFTs to users upon purchase. These NFTs are issued based purely upon luck, with users given an NFT corresponding to a random number draw.
In order to randomly distribute these NFTs to users securely and without bias, we needed access to a secure random number generator (RNG) that any user can independently audit. However, RNG solutions for smart contracts require several security considerations to prevent manipulation and ensure system integrity. For instance, RNG solutions derived from on-chain data like block hashes can be exploited by blockchain miners via reorg attacks, while RNG solutions derived from off-chain data providers are opaque and don’t provide users with definitive proof about the integrity of the process.
After reviewing various solutions, we selected Chainlink VRF — a tamper-proof and publicly auditable RNG solution that will help ensure our NFT distribution is verifiably fair. As a result, users can trust that the NFTs they receive have been issued as a result of a truly random process without bias.
Chainlink VRF works by combining block data that is still unknown when the request is made with the oracle node’s pre-committed private key to generate both a random number and a cryptographic proof. XANALIA will only accept the random number input if it has a valid cryptographic proof, and the cryptographic proof can only be generated if the VRF process is tamper-proof. This helps provide users with automated and publicly verifiable proof that each XANLIA blindbox using Chainlink VRF for randomness is provably fair and was not tampered with or predicted by the oracle, outside entities, or the XANLIA team. XANALIA’s First Blindbox collection “Monkey King” ended 6th October sold out for 427,570 USD.
Ultimately, having access to a verifiable source of randomness helps ensure the integrity of our randomized NFT draw, giving all users a fair opportunity to attain high-value NFTs.
Chainlink is a decentralized oracle network that enables smart contracts to securely access off-chain data feeds, web APIs, and traditional bank payments. Chainlink is consistently selected as one of the top blockchain technologies by leading independent research firms such as Gartner. It is well known for providing highly secure and reliable oracles to large enterprises (Google, Oracle, and SWIFT) and leading smart contract development teams such as Polkadot/Substrate, Synthetix, Loopring, Aave, OpenLaw, Etherisc, Conflux, and many others..
