Revocation of Entry

The membership of an entity in a blockchain network is dependable on its repu-

tation. Network D is no exception. To revoke the membership all that needs to be

done is put in a Revocation record in the Ledger. This too can be easily done using

the build_revoc_reg_entry_request and sign_and_submit_request Ledger APIs from

Hyperledger Indy at the time of writing.

Active Use Cases of Hyperledger Indy

The three active use cases are:

a.

Kiva’s launch of Africa’s first national decentralized ID system with Hyper-

ledger Indy: Kiva, a US charitable association centered with respect to mone-

tary consideration has constructed Kiva Protocol to help empower widespread

monetary access. In 2019, Sierra Leone, a West African country of around 7

million, dispatched the National Digital Identity Platform (NDIP) that utilized

Kiva Protocol to empower quick, modest, and secure character check for its

residents. It allows citizens to perform electronic Know Your Customer (eKYC)

verifications in about 11 s, using just their national ID number and a fingerprint.

b.

CULedger protects credit unions against fraud with Hyperledger Indy:

CULedger worked with decentralized personality association, Evernym, to

fabricate a recognizable proof arrangement that was quicker, less complex, and

safer with Hyperledger Indy—a dispersed record programming project that is

interoperable with other blockchains or can be utilized all alone to control the

decentralization of identity. It has brought the interoperability and portability to

scale towards a newer height.

c.

The Verifiable Organizations Network (VON), started by the governments of

British Columbia, Ontario, and Canada, aims to cut government red tape with

Hyperledger Indy.

Hyperledger Indy use cases can be found in the areas of digital documentation,

password-less authentication, software vulnerability attack, tackling spam, docu-

ment provenance, education and employment verification, decentralized membership

management, and global accessibility.

The entire digital identity community is looking forward to Hyperledger Indy for

a safe, secure, and serene future. There is a huge chance to succeed.
