Understanding Self Soverign Identity Part -I

Few terms to know before we dive into SSI

What are credentials?

Physical Credential/ID card

For Example

  • You work in an organization
  • You are the owner of a user Id.

What is Identity Owner/Principal/Holder?

Problems with traditional credentials

· Easily lost or damaged

The only damaged :) :) but not misused thankfully

· Expensive to create or issue

· Can’t be verified easily

· Reveals more information than needed

What are Verifiable credentials?

Properties of CVs

· All digital and under the owner’s control

· Highly scalable

· Very hard to fake or impersonate

· Enables minimum disclosure (Bouncer only needs to know your age)

· Much hard to impersonate (Uses PKI)

· Enables Zero-knowledge Proofs

· Data by Itself becomes useless to thief

How do you get Verifiable Credentials?

Generated and assigned and used.

Issuer

Holder

Verifier

1. Govt issues (Issuer) liquor license to the shop owner (Holder)

2. Shop Owner (Holder) shares his license to the customer (verifier)

Distributed PKIs (DIDs)

2. Anyone on the ledger can know who the Issuer DID belong to (BB Curry’s DID is DID123)

3. Issuer also provides revocation policy and it’s signed by issuers DID

4. Now issuer is ready to issue credentials to Bob.

5. Now Bob can show the credentials to prove the identity to Joe’s Bank

6. Joe’s Bank knows that Sam’s Card has been issued and is able to verify without contacting Sam’s Card

In the upcoming article, will continue with terms and we will get our hands dirty with sample examples. If you have questions please feel free to leave comments and if you have feedback, would be appriciated.
