2 years ago Hi @vojtech-vrba, the description is a bit off IMO, as TLS connections are not allowed in the context of a blockchain. Later on you describe an ETH->Secret relayer of Chainlink data, and a secret contract that stores the data on Secret, which is unrelated to "TLS connection from validator enclaves". Therefore I would ask you to edit either the intro or the project description to accurately reflect your proposal.
Also, in the project description please specify how users on Secret can verify the validity of the data that's stored inside the secret contract.

Secret Oracles: provide price feed data on-chain
High-level description of the project
This project aims to bring Chainlink price feeds directly to the Secret network. So any app can work with reliable price feed data without having to leave the Secret Network.
Referring to 2021 Devpost hackathon: https://devpost.com/software/chainlink-oracles-bridge-to-secret-network#updates
The basic idea is to provide added value to developers on Secret network by providing on-chain data from Chainlink on Ethereum , so they can use such oracles within their smart contract without a need to asynchronously use chainlink or other oracle providers
Problem / solution
Speed is what matters at first. Fees are what matter second.
Writing and operating smart contract in some cases requires access to off-chain data (like price feeds) and using oracle networks like chainlink is reliable, but creates small problém. Such data are not available on the fly, smart contract needs to initiate call of oracle network, than is suspended and waits for chainlink to answer within next blocks. So, Chainlink started to write such data directly into Ethereum blockchain, so smart contract can get such data within their run without interuption and waiting for asynchronous answer.
We would like to build a system, which will be operated by us (for defined time period) , which periodically copy data from Ethereum (and quite easily could be added other data sources) and writes them to Secrert blockchain, so any smart contract could read them and utilize them within their run.
The primary goal of such solution is to provide other smart contract developers option for using such data and honestly speaking, without intentention to be 100% reliable and decentralized and to build complete ekosystém as chainlink. Plan is to provide commonly usable data on chain, so developers could use them within their contracts. In case they need 100% reliability and decentralized solution, they shall use chainlink or other oracle networks with their fees and principles. But we strongly believe that for Secret network is added value to provide such service for their developers even with small risk of hacks and malfunction.
Product description
Building a Mirror-like feed will be the quickest way to connect your smart contracts to the real-world market prices of assets. For example, one use for data feeds is to enable smart contracts to retrieve the latest pricing data of an asset in a single call.
Data batches will be packed into a single aggregate transaction, saving a significant amount of gas — using Chainlink OCR.
Project components:
Data collector - An Ethereum Network client: to pull Chainlink contracts data, or listen to their emitted events
The dedicated Secret contracts that get updated by the off-chain service and their data consumed by other contracts
