(GDPR, PDPA, PDPB etc.) across the world formulated on the

privacy of personal data.

But, can’t the Identity solutions be handled without Blockchain?

Please note that the identity solutions can be implemented using

centralized storage (i.e., without Blockchain) and yet the DID

implementations come with many benefits broadly categorized as

security, controllability, and portability as represented in Table 17.1

as follows:

Security

Controllability

Portability

The identity information

must be kept secure

The user must be in

control of who can see

and access their data

The user must be able to

use their identity data

wherever they want and

not to be tied to a single

provider

Protection

Existence/User-centricity

Interoperability

Persistence/Longevity

Control

Transparency

Minimization

Consent

Access

Table 17.1: Features of DID solutions

17.3 World Wide Web Consortium

While developing a project in the decentralized identity that involves

relatively an emerging space, it’s desirable to understand the new

features that DID can offer and, at the same time, not get into any

loopholes in this nascent technology. Founded in 1994, the World

Wide Web Consortium or W3C is the prime organization for setting

the international standards for the world wide web. Its main mission

is to develop the protocols and guidelines that ensure long-term

growth for the web. W3C perhaps is the first consortium that came

out to develop a set of protocols to define “Decentralized Identifier”

or DID.
