The ALTGAS Foundation is developing an open alternative gas ecosystem for a variety of practical business models.
A business based on ALTGAS implies the presence of a decentralized data market and incentives for p2p exchange of any values (including not purely cryptocurrency).
As an example, the “DAD” business model allows you to create such a market and offers tools to protect values and sell them.
For example, a business card exchange service. “Jigsaw on BlockChain” service - a decentralized exchange of business cards can be implemented on the basis of DAD.
Why is such a service even needed if there is LinkedIn?
If you consider a photocopy of a business card as a long-term value (potential contact value), then together with LinkedIn it strengthens the trusted contact factology (for example, an independent check that the data in LinkedIn is not a fake).
In general, any open data is well suited for the ALTGAS-DAD business model. Including, for the purpose of their independent decentralized verification and confirmation or refutation.
