The document provides an overview of decentralized applications (dapps), explaining their nature, advantages over traditional apps, and their development. It discusses key aspects such as blockchain technology, smart contracts, types of dapps, and common drawbacks, while highlighting examples like Augur and Uniswap. The dapps market is projected to grow significantly, driven by their transparency, reliability, and evolving technology opportunities.

3. Introduction into
DApps
WHAT IS A DAPP?
A DApp or Decentralized
Application has its backend code
running on a decentralized peer to
peer network.
Contrast with an app where the
backend code is running on
centralized servers.

4. BLOCKCHAIN TECHNOLOGY
• Blockchain is an Open Distributed ledger
• that can record transactions between two parties,
• Efficiently and in a Verifiable and
• In a Permanent Way

6. SMART CONTRACTS
• “Set of Promises,
• Specified in Digital Form,
• Including Protocols
• Within which the parties perform on these promises.”
• They are Immutable and
• Distributed
Nick Szabo , 1996

DAPP DEVELOPMENT

9.  Decentralized : dapps operate on Ethereum, an open public
decentralized platform where no one person or group has
control.
 Open Source : Source code of the DApp is available to all.
 Resistance to Censorship: No single entity on the network
can block users from submitting transactions, deploying
dapps, or reading data from the blockchain.
 Rewards: Reward system allows decentralized messaging
app users to earn crypto.
 Complete Data Integrity: Data stored on the blockchain is
immutable and indisputable, thanks to cryptographic
primitives. Malicious actors cannot forge transactions or
other data that has already been made public.
 Privacy: You don’t need to provide real-world identity to
deploy or interact with a dapp.
 Zero downtime – Once the smart contract is deployed on
the blockchain, the network as a whole will always be able
to serve clients looking to interact with the contract.
Malicious actors, therefore, cannot launch denial-of-service
attacks targeted towards individual dapps.
 Blockchain and Smart Contracts

10. DAPPS OVER REGULAR APPS

11. Traditional Applications (Apps) Decentralized applications (DApps)
Centralized in nature, meaning they
are owned and operated by a specific
entity
Decentralized in nature, meaning a single
entity does not have control over it
Based on the Web 2.0 version of the
internet
Based on the Web 3.0 version of the
internet i.e. the blockchain
Less privacy as the user has to provide
details about their identity in most
cases to access apps
Increased privacy with no need to give
away personal information
Usually do not run in an open-source
environment
DApps run in an open-source
environment

12. TYPES OF DAPPS
Type 1:
DAPPS have their own Blockchain.
Type 2:
Dapps that leverages the Blockchain of Type 1 apps.
Type 3:
Dapps that use the Protocol of the Type 2 apps.
For eg, SAFE Network (Secure Access for Everyone)

13. DRAWBACKS OF DAPPS
Maintenance
Performance Overhead
Network Congestion
User Experience
Centralization
Immutable
Expensive

14. EXAMPLES
Following are a few of the application examples of dApps:
 Augur: A decentralized prediction marketplace based on Ethereum
 Uniswap : US based DApp on Ethereum blockchain. It allows users to
swap and trade ERC-20 tokens.
 Aave: most popular DApp in DeFi world. Its an open source liquidity
protocol.
 Bit Torrent: A decentralized file-sharing application
 Golem: A decentralized marketplace for renting computational power
and resources
 Cryptokitties: A decentralized game application
 Minds: A decentralized social media platform between content creators
and consumers

15. FEAUTURES PROSPECTS AND
CONCLUSION
This has led us to the end of the discussion, and from the above discussion, it is
clear that dApps outstands when compared to regular mobile apps in terms of
transparency, reliability, flexibility, and scalability, and these factors are
stimulating the global DApps Market.
If we look at the statistics, it was estimated that the market size of dApps was
valued at USD 10.52 Billion in 2019 and is expected to reach USD 368.25 Billion
by the year 2027 at a CAGR of 56.1%. The rising demand for fast transaction
processes and the advantages of DApps in terms of transparency, reliability,
flexibility, and scalability are spurring the global dApps market.
Since dapps are new innovative technologies, learning how to build dApps on
Ethereum can bring tremendous career opportunities in the Blockchain space.
