LuckQuick Integrates Chainlink VRF and Automation to Help Power Lucky Draw Games

We’re excited to announce that LuckQuick — a lucky draw game platform — has integrated Chainlink VRF and Automation on BNB Chain mainnet. By integrating the industry-leading decentralized oracle network, we now have access to a tamper-proof random number generator and decentralized smart contract automation service needed to help build a Web3 lucky draw game platform while providing users with high assurances of transparency, fairness, and decentralization.

Here’s how each piece of Chainlink infrastructure helps to power seamless functionality in LuckQuick.

Provable Lucky Draw Game Randomness With Chainlink VRF

Blockchains don’t inherently have a secure random number generator, which means to build a lucky draw game, teams like ours have to create one ourselves or find an external solution. On-chain RNG solutions like block hashes introduce vulnerabilities where miners can choose to publish a block only when it would generate more favorable results for themselves. On the other hand, off-chain RNG solutions are opaque, requiring users to trust that the centralized data provider won’t manipulate the results to their benefit. Both solutions become increasingly concerning as the amount of value being secured by the RNG solution goes up.

That’s why we chose Chainlink VRF, which 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. The LuckQuick 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 helps provide users with automated and publicly verifiable proof directly on-chain that each winner selected using Chainlink VRF for randomness was chosen in a provably fair and tamper-proof manner that is unable to be predicted by the oracle, outside entities, or the LuckQuick team.

Reliable Game Function Execution With Chainlink Automation

Because lucky draw games on LuckQuick will be continuous events, we saw the need to implement an automation service that uses time intervals to both start lucky draw rounds and pull random numbers from Chainlink VRF.

To clarify, smart contracts need an automation service because they don’t have the native ability to trigger their own functions. For example, let’s say the LuckQuick lucky draw game has a start() function that begins a new game round. If we want a game round to start every 10 minutes, an external entity must manually trigger that function.

The Chainlink Automation Network allows smart contracts to outsource regular maintenance tasks to professional DevOps, which serve as trust-minimized, hyper-reliable, economically incentivized, and decentralized automation nodes. It allows users to define Chainlink Automation jobs, which are performed for a fee using a professional network of node operators, which rotate taking on these jobs.

A few standout features of Chainlink Automation include:

  • Highly reliable, performant, and decentralized automation — Chainlink Automation ensures transactions are identified and confirmed quickly even during periods of heavy network congestion by leveraging Chainlink’s battle-tested transaction manager.
  • Time-tested infrastructure that helps save costs — Chainlink Automation enables us to eliminate in-house automation infrastructure costs, reduce resources spent on DevOps, and increase speed and efficiency.
  • Built to enable faster scaling — Chainlink Automation enables us to scale faster and avoid the challenges that come with building and maintaining the infrastructure needed to reliably automate across multiple chains.
  • Unlocks new use cases — With smart contract automation, we’re able to explore new use cases and unlock capabilities that would otherwise not have been possible.
  • Easy-to-use — Developers are able to schedule time-based automation jobs in seconds using the Chainlink Automation Job Scheduler’s no-code UI.

“Using Chainlink as critical infrastructure for our core lucky draw game product was a no-brainer. With a decentralized architecture, a proven history of performance, and an easy integration process, Chainlink provided us with best-in-class infrastructure that makes secure functionality for LuckQuick possible.” .” –Jorge Guanipa, development team.
