Looking for an experienced developer to help build an off chain , decentralised, transparent, and secure price feed for decentralized synthetic exchanges using Gun, the distributed graph database library. The project will involve creating a curated list of API providers deemed trustworthy and reliable by the community, with each node on the network connecting to only one provider from the list. A consensus mechanism will also need to be implemented to allow the community to vote on adding or removing providers from the list. Gun's graph database functionality will be used to store and manage the pricing data received from each API provider, allowing for easy querying and retrieval of data by the Chainlink nodes. To ensure off - chain security and validity, Zero-Knowledge (ZK) proofs will need to be implemented to verify the accuracy of the pricing data reported by each node. Additionally, Chainlink nodes will be implemented to request a median price from the network in a transparent, secure, and open manner, ensuring trustlessness and permissionlessness in the Web3 ecosystem. The ideal candidate will have experience with Gun, graph databases, consensus mechanisms, ZK proofs, and Chainlink nodes. They should also have a deep understanding of decentralized finance and Web3 technologies. Please note that proposals that do not include a project plan will be ignored. If you're interested in this exciting opportunity to contribute to the growing Web3 ecosystem, please submit your proposal with a detailed project plan and timeline. We look forward to hearing from you !

Hello, Greetings! we are excited to submit our proposal for the development of an off-chain, decentralized, transparent, and secure price feed for decentralized synthetic exchanges using Gun, the distributed graph database library. We understand that the project requires the creation of a curated list of trustworthy and reliable API providers, with each node on the network connecting to only one provider from the list. We are confident in our ability to implement a consensus mechanism that allows the community to vote on adding or removing providers from the list. Our team has extensive experience with Gun's graph database functionality and can effectively store and manage the pricing data received from each API provider. We are also well-versed in the implementation of Zero-Knowledge (ZK) proofs to verify the accuracy of pricing data and the use of Chainlink nodes to request a median price from the network in a transparent and secure manner. Our team's deep understanding of decentralized finance and Web3 technologies, combined with our experience with consensus mechanisms and ZK proofs, makes us the ideal candidate for this project. Looking forward to hearing from you soon. Thank you& Best Regards Team Owebest || KD

Hi, My expertise in blockchain development, specifically in Ethereum-based decentralized finance, along with my knowledge of Gun graph database library, makes me an ideal candidate for this project. Additionally, my proficiency in consensus mechanisms, Zero-Knowledge proofs, and Chainlink nodes will enable me to implement the necessary functionalities required for this project. My proposed project plan would involve developing a curated list of reliable API providers and implementing a consensus mechanism that allows community voting to add or remove providers from the list. This list will be connected to Gun's graph database functionality, allowing for easy querying and retrieval of data by Chainlink nodes. To ensure off-chain security and validity, ZK proofs will be implemented to verify the accuracy of pricing data reported by each node. Finally, Chainlink nodes will be deployed to request a median price from the network, ensuring transparency and security. My goal is to deliver a decentralized, transparent, and secure price feed for decentralized synthetic exchanges that will function seamlessly with Chainlink nodes. You can go through my profile for a better understanding of the past projects that I have done related to your requirement Regards Rahul
