three that comes to mind are remote voting, smart agriculture, and

CBDC. While I am covering the first two here, CBDC would be

covered in the next chapter.

17.5.1 Use Case - Remote Voting

One of the most anticipated use cases in the Blockchain space today

is remote voting. People have to travel all the way to a particular

place at a particular time to cast their vote that goes to a centralised

system. What the ecosystem needs is a solution, using which the

people can cast their vote either from their own mobile device, a

website, or from a kiosk. However, unlike the other Blockchain use

cases, remote voting needs additional security and privacy. Some of

the special challenges in this use case are as follows:

There can be a denial-of-service attack on a centralized server.

The voter can come up with a fake identity.

The voter might try to cast vote multiple times.

The voter should be able to check if his/her vote is cast for the

right candidate.

Privacy of the user’s vote should be protected.

The ecosystem should be able to handle the massive load.

All these issues can be handled efficiently by using Blockchain. With

appropriate decentralized identity solution along with live biometrics,

one can vote from any place in the world. The solution should work

for the tech-savvy who can cast votes from the EarthId App and also

for the common man who has no access to the smart devices. Many

countries in the world are researching to come up with such a

solution that can also scale well.

17.5.2 Use Case – Smart Agriculture

As shown in Figure 17.7, now the Animals too can have their own

decentralized digital identity to help them send their status updates

to the rightful owner from their IoT devices, as follows:
