What is a Dapp?
Decentralized application is a program which is run by many people which either
uses or creates a decentralized network for some specific purpose

Property Transfer Using Traditional System
Problems
Currently, we use the central authority
to transfer the property ownership.
This makes it time consuming and
attracts a lot of extra expenses too
with an additional burden of
document management. Also, since
the system is centralized, there is
always a possibility of fraudulent.

24. Ethereum Developer Certification Course www.edureka.co/ethereum-developer-course
Property Transfer On Blockchain
Advantages
Blockchain has the potential of
transferring title of the property on
the same day
*
A digital record with permanent audit
trail can be instituted, this means that
governments, banks, agents, can
easily access the chain of data
pertaining to that property
*
This will reduce fraud and ensure that
properties cannot be sold thrice over
to the same entity.
