A data ownership platform that pays users for their data from the not-for-profit Cirus Foundation. Founded in 2020, a Chrome browser extension allows users to decide how much data they want to sell. Payment is made in Cirus tokens to the user's digital wallet, and the tokens are exchangeable for other crypto or cash. Using technology from Cubera International, the blockchain-based platform was created to aggregate and sell the data to advertisers. The Cirus Layer 2 blockchain handles the transactions and summarizes them on the Ethereum network. See
Layer 2 blockchain.
The Real Ownership Economy?
A few years ago, a lot of press in the DeFi community was about crypto enabling the "ownership economy" by creating capital via new tokens as well as loaning or staking crypto for rewards. Getting paid for one's data, which people freely give up every time they search for something over the Internet, was indeed a revolutionary approach. 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 the keys to all the curated data that flows through the user's browser and router. Over time, the dNFT increasingly rewards the user with more Cirus tokens.
