That is exactly what is written in their whitepaper. In the beginning, Datum is placing the responsibility of the validation onto the buyers.
But that opens up exploits from both sides.
Let's say you are selling your medical records. Insurance brokers will pay a lot of money for that.
- Once the broker has your data off Datum and has not paid yet, he can claim the data is forged.
- If the broker did pay first, then notices it is fake data, you already have your money.
And how would you say could you prevent such exploits?
If Datum itself doesn't want to be responsible for the validation the only way I could imagine it can work is that another, independent party gets involved for validation and mediating the payment process.
If I knew a way to validate data, that is, to be able tell absolute truth, I would not say it in here. I would start my own business. I would also get 5 Nobel prizes for the end of lies, identity theft, fraud, scientific uncertainty and last but not least, the end to the question whether extraterrestrial life exists
Anyway, Datum plans to add a trust ranking system for all parties and linking accounts to identification services such as Civic.
