The SSI system gives you the ability to use your digital wallet and authenticate your own identity using the credentials you have been issued. You no longer have to give up control of personal information to dozens of databases each time you want to access new services, with the associated security risk.
A number of established SSI initiatives already exist and the world of data in general, and blockchain in particular, would greatly benefit from universal standards in technology and regulation.
To the individual, Tapmydata offers the first step towards building their own sovereign ID - a digital profile of verified personal information independent of any organisation, while presenting an on-ramp to more complex SSI services as they become available.
