With the upcoming launch of the Roraverse raffle, Rora Realm is excited to announce that we have integrated Chainlink Verifiable Random Function (VRF) and Chainlink Keepers on BNB Chain. By integrating the industry-leading decentralized oracle network, we now have access to a tamper-proof and auditable source of randomness needed to help select winners in our Roraverse raffle. Thanks to our integration of Chainlink VRF, players can have higher confidence that all users have a fair opportunity of winning prizes while enjoying the fun new game!

Chainlink Keepers helps us automate the draw process seamlessly and in a decentralized manner. By integrating the time-based trigger system that Chainlink Keepers offers, our draws are seamlessly and autonomously processed, week in, week out.

How the raffle works:

The raffle will start every Sunday at 7pm UTC. Tickets can be purchased with RORA tokens.
$1 in RORA = 1 ticket. At the end of the time frame, the raffle is drawn.

For each raffle, there are 11 winners: 1 winner wins 50% of the total prize pool, 10 winners win 25% of the total prize pool. 20% of the prize pool is burned and 5% of the prize pool goes to the Rora treasury.

- Winners are drawn on Sunday at 6pm UTC

- New raffle starts an hour later, at 7pm UTC

Winners are determined by random selection, underpinned by Chainlink VRF’s provably fair RNG, taking into account how many tickets each person has purchased. More tickets = higher chances to win.

We have a feeling that our new raffle is going to be very popular. For this reason, we felt it was important to bring transparency and security to the winner selection process so no single party could unfairly influence the results.

Chainlink VRF

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. The Rora Realm 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 raffle winner selected is done by using Chainlink VRF for randomness is provably fair and cannot be tampered with or predicted by the oracle, outside entities, or the Rora Realm team.

Chainlink Keepers

Rora Realm has also integrated Chainlink Keepers into our raffle system to help automate the draw process to execute at the same time every week.

Chainlink Keepers offer a multitude of benefits, including:

  • High Uptime — Chainlink Keepers are run by the same professional DevOps teams that have an established on-chain performance history of providing high reliability to Chainlink Price Feeds during extreme network congestion and market volatility.
  • Low Costs — Chainlink Keepers have several gas-optimizing features that lower the costs of automating maintenance tasks for users, including a rotating node selection process to prevent gas price auction wars and stabilize costs.
  • Decentralized Execution — Chainlink leverages a decentralized and transparent pool of Keepers to help provide strong guarantees around secure contract automation, saving teams time and mitigating the risks around manual interventions or centralized servers.
  • Expandable Computation — Chainlink Keepers perform off-chain computations and generate calldata verifiable by smart contracts, allowing developers to build advanced, trust-minimized dApps at lower costs.

“Chainlink features best-in-class oracle infrastructure that powers a significant proportion of Web3. To provide transparency to our community, we knew we needed to integrate Chainlink VRF to access a provably fair source of randomness for our raffles. By integrating Chainlink Keepers, we are able to automate key processes in a secure, reliable, and decentralized manner.” — Kai, Co-Founder, Rora Realm.

About Chainlink

Chainlink is the industry standard for building, accessing, and selling oracle services needed to power hybrid smart contracts on any blockchain. Chainlink oracle networks provide smart contracts with a way to reliably connect to any external API and leverage secure off-chain computations for enabling feature-rich applications. Chainlink currently secures tens of billions of dollars across DeFi, insurance, gaming, and other major industries, and offers global enterprises and leading data providers a universal gateway to all blockchains.

About Rora Realm
Rora Realm is a culture token and decentralized intellectual property (D-IP) in the form of a liquid token. The IP revolves around the character known as Rora, her Guardians and all the elements within the universe known as the RORAVERSE.

It is a gamified collaborative community experience, with community members being referred to as Rora’s Guardians.

We have created the first ever shill2earn and create2earn ecosystem in order to create initiatives in the form of daily bounties & missions that offer payment for completing tasks.

With the growth of the Rora brand, the team builds Rora themed dapps in order to continuously drive utility. We are also monetizing the Rora brand across various industries: gaming, entertainment, merchandise, clothing, and more in order to generate multiple revenue sources for the ecosystem.

The RORA token is necessary to gain an ownership stake in the Rora Realm property rights. Giving you the power to make and sell your own Rora-themed NFTs, applications, and merchandise. It is also the primary payment token for all Rora-related products and utilities.

The token will also give Guardians the power to create, upgrade and acquire special NFT assets, gain access to exclusive Rora applications and events. As well as voting for on-chain governance proposals to determine future features, policies, content, and utilities. Tokens are also used to reward community members for winning bounties, missions, and completing special tasks by participating in our shill2earn & create2earn gamified community experience.
