Yep I saw but they explain the difference with standard data brokers and not Datum that has just finished their ICO to create a decentralized data wallet and marketplace where you can monetize your data too. Businesses will be able to buy via an API as well. So it looks pretty similar.
Datum has an API for raw data which, as explained in the post, has little to no value to companies.
Okay. Datum has never been very clear anyway, not sure they know that actually. Cool. So you are going to build you own blockchain protocol, if I well understood the whitepaper? Are you forking from an existing platform or building from scratch?
The first iteration is build on Ethereum, and DataWallet have partnered with QTum to build their next iteration on the QTum chain.
