Summer of WAMO Dali Web3 Fest Integrates Chainlink VRF to Help Randomize the WAMO NFT Reveal Process

We’re excited to announce that Summer of WAMO Dali Web3 Fest—a festival in Yunnan Province, China—has integrated Chainlink Verifiable Random Function (VRF) on Ethereum mainnet. By integrating the industry-leading decentralized oracle network, we now have access to a tamper-proof and auditable source of randomness needed to help power a fair NFT reveal for the 3,706 WAMO NFTs given to contributors, sponsors, and participants who attended the festival. Ultimately this creates a more exciting and transparent user experience, as all our Dali Web3 fest guests have higher assurances of a fair NFT revealing process.

In early 2021, 706 came to Dali. Intoxicated with its pleasant climate, beautiful scenery, and inclusive and open culture, 706 established the "706 Dali" community. Since the epidemic, more Web3 enthusiasts and digital nomads have come here. To some extent, Dali has gradually become the Web3 center of China, especially for DAOs. We want to share the diverse creativity of Dali with all our Web3 friends and invite all of them to the party to connect and have a good time together. In the spirit of WAMO, we will be hosting the Summer of WAMO Dali Web3 Fest this August, 19-20th. Every ticket holder can mint two free provably random WAMO NFTs, which are revealed fairly using Chainlink VRF.

In order to secure our NFT reveal, 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 derived from blockchain data like block hashes can be exploited by miners/validators, while off-chain RNG solutions derived from off-chain APIs 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 a time-tested oracle network, 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. The WAMO NFT 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 the reveal process of WAMO NFTs is provably fair and was not tampered with by the oracle, outside entities, or the Summer of WAMO Dali Web3 fest team.

We created WAMO, the mascot of our Web3 fest based on a tile cat—a Dali mythical creature that’s a very powerful tutelary deity. It represents the spirit of positive externalities, an embodiment of reason, consensus, open source, and optimism. We hope the spirit of WAMO will help humanity grow by aligning our incentives towards the well-being of each other, facilitating co-creation, better coordination, and positive-sum outcomes. 

“We are excited to integrate Chainlink VRF into the reveal process of our WAMO NFT collection, providing our users with higher assurances of a fair NFT reveal.”  – Pablo Li, Contributor for Summer of WAMO | Dali Web3 Fest

About Summer of WAMO | Dali Web3 Fest

With the genesis of 706Dali, Summer of WAMO | Dali Web3 Fest is not only the first Web3 festival in Dali, but also the first massive Web3 event in China that is owned, co-created, and organized only by its members. Summer of WAMO | Dali Web3 Fest will bring together Web3 & DAO communities to hear from the most sought-after thoughts and experience a wide range of discussions, meetings, parties, music performances, dinners, fireside chats, and much more. This is the only outdoor festival showcasing and celebrating all sides of the DAO, crypto, NFT, and Web3 ecosystems. We are dedicated to bringing DAO, crypto, NFT, and Web3 ecosystems all in one place to learn from each other, connect & collaborate. We will create spaces for empowerment, openness, and collaboration, and bring together top technical talents, entrepreneurs, incubators, project teams, and DAO members, for deep dialogues, connections, and co-creation. We hope you can find like-minded people here and be inspired. We hope we can build a place where communities move forward together. Together we create opportunities for onboarding, ideation, debate, positive-sum discussion, and spreading Web3 & DAO vibes.
