Polypulsar Integrates Chainlink VRF to Secure PvE and PvP Games!
We’re excited to announce that Polypulsar, a seamless hybrid of blockchain gaming and yield farming, has integrated
Chainlink Verifiable Random Function (VRF) on the Polygon mainnet. By integrating Chainlink’s industry-leading decentralized oracle network, we now have access to a tamper-proof and auditable source of randomness needed to ensure that NFT characters and pets complete the missions and fight randomly and fairly. Ultimately this creates a more exciting, transparent, and fraud-proof user experience, as users can rest assured that the RNG function in the games is fail-proof and everyone can enjoy a fair competition.
sar is a project building blockchain games and offering yield farming features.
In order to ensure that the results of our games cannot be manipulated, we need access to a secure random number generator (RNG) that any user could independently audit. However, RNG solutions for smart contracts require several security considerations to prevent manipulation and ensure system integrity. For instance, RNG solutions using on-chain data like block hashes can be exploited by blockchain miners, while off-chain RNG solutions like traditional 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 because it’s based on cutting-edge academic research, supported by Chainlink’s time-tested oracle infrastructure, and secured through the generation and on-chain verification of cryptographic proofs that prove the integrity of each random number supplied to smart contracts.
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. Polypulsar games’ smart contract 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 provides our users with automated and verifiable assurances directly on-chain that Polypulsar games are provably fair and cannot be tampered with by the oracle, outside entities, or the Polypulsar team.
Our team also plans to integrate Chainlink into off-chain games we build in the future. These games will offer equippable NFT items which can be worth thousands of dollars; thus, it is very important for us to ensure that these items cannot be acquired through the exploitation of RNG functions.
Chainlink is the industry standard oracle network for powering hybrid smart contracts. Chainlink Decentralized Oracle Networks provide developers with the largest collection of high-quality data sources and secure off-chain computations to expand the capabilities of smart contracts on any blockchain. Managed by a global, decentralized community, Chainlink currently secures billions of dollars in value for smart contracts across decentralized finance (DeFi), insurance, gaming, and other major industries.
Chainlink is trusted by hundreds of organizations, from global enterprises to projects at the forefront of the blockchain economy, to deliver definitive truth via secure, reliable oracle networks. To learn more about Chainlink, visit
