A platform from the Cirus Foundation that paid users for the data they sold to advertisers. Founded in 2020, a Chrome browser extension lets users decide what to sell, and payment is made in Cirus tokens. The Cirus Layer 2 blockchain summarizes the transactions on Ethereum. See

The Real Ownership Economy?
In the early 2020s, a lot of press in the DeFi community was about enabling the "ownership economy" and creating capital via tokens. Getting paid for one's data, which people freely give up every time they search over the Internet, was revolutionary. However, in 2021, the Cirus token was over a dollar, but by mid-2024, its value dropped to less than one cent. See

The Cirus Data NFT (dNFT)
Cirus created the first "data NFT," which contains keys to all the curated data that flows through the user's browser and router. Over time, the dNFT rewards users with more tokens.
