The Spark Project is a decentralized network of individuals and businesses that have agreed to make their financial data available for analysis. The network first launched in his August 2018, but the project has been active since at least 2016.
Spark projects are based on off-chain data exchange protocols such as Oracleize and ChainLink. These decentralized networks allow participants to combine their own financial data with that of others for a comprehensive view of the global economy.
The Spark project offers various services that allow users to access this off-chain data. Users can use the app on their mobile phone or computer to scan a QR code containing information such as their credit score, age and gender. The app then displays this information on a map along with other relevant data points such as local crime and employment rates.
