We are pleased to announce that the Connexun Chainlink node is now live on mainnet, enabling smart contracts to access our premium news event data directly on-chain. Developers can now call our Chainlink node to get a cryptographically signed sentiment index for the crypto industry that’s updated in real-time based on recently published news articles across the globe. The solution is ideal for those looking for real-time sentiment data on distinct cryptocurrencies (ie Bitcoin, Ethereum, Cardano) or looking for the real-time score on the industry as a whole.

The data is powered by tens of thousands of news sources screened on a daily basis in different languages. It can be used to create new types of on-chain prediction markets and automated trading strategies based on highly refined crypto sentiment analysis. In the future, we plan to bring additional datasets on-chain like political election outcomes, important legislation passings, and major market or business events.

Being the industry’s leading oracle solution, Chainlink provides a quick and easy way to get our existing suite of APIs compatible with leading blockchain networks. Not only will we be able to supply data to any current or future blockchain, but we can cryptographically sign our data on-chain to prove it originated from our API. The node setup process was also very straightforward, ultimately introducing our data into a vast array of blockchain-based markets.
