Abstract: Crowdfunding as the name relates its raising of funds from a vast number of sources.
This can be an individual or an organization who merely wants to contribute for a noble cause.
In layman terms, it can be referred to as funding given by an anonymous crowd with a belief
that they are helping a section of the society to fight and overcome their monetary problems.
This is being achieved via the Internet where people or groups raise funds to help others during
a natural catastrophe or some community-oriented social projects, entrepreneurial ventures,
travel, medical expenses and many more. The present-day scenario is such that once people
transfer money into a particular venture no one knows what happens to the money generated. As
a solution, one needs to track down the flow of money and thereby maintaining appropriate
transparency. We propose an approach through this paper, of a decentralized system built using
Blockchain Technology where once the investor funds money to a venture the transactions will
be captured. If incase, the endeavor initiated accumulates the money within the stipulated time
then it is utilized or else the money is returned back to the investor. This platform will eliminate
the middlemen completely. It is transparent and more secure and thus acts like a huge savior for
the people in need. A decentralized approach to crowdfunding forfeits all fees for the investor,
gives the receiver more share of the project, and allows for a peer-to-peer relationship between
the investor and receiver.
Keywords - Crowdfunding, Blockchain, Smart Contracts, Peer-to-Peer Network, Internet.
1.Introduction
Crowdfunding refers to a project meant for gathering funds. This can be for varied
reasons ranging from as severe as a natural calamity or may be small amounts of
money to help people for their work or projects through the Internet[1]. The present
model of crowdfunding solely revolves around three kinds of players they are
projected initiator one who suggests the idea, people or group of people who fund the
project and organization that is responsible for bringing parties together[2]. In the
system, interested people or collective investors who fund the project are led to the list
of initiated projects appearing on the dashboard. The project initiator creates a project
by giving its description and linking his metamask account to the project. The
organization keeps track of all the activities done in the system. This can be divided
into four categories: reward crowdfunding, social crowdfunding, equity crowdfunding,
6
and peer-to-peer funding. Social and reward crowdfunding is raised for charitable
causes [10]. Equity crowdfunding is a technique of raising capital through selling of
stocks to a number of individual investors using the equivalent method as crowd-
funding [3]. Peer-to-peer funding refers to the use of an online platform to unite the
lenders/investors with borrowers/issuers in order to provide unsecured loans.
It serves as a way to overcome the financing gap in the primitive stages of a novel
.
project Funding from venture capitalists and banks is usually available only in the
later development phases of start-ups [4]. In the initial periods of a company’s
development cycle, a large amount of the fund is contributed by the founder himself
or to some extent by his friends and family. If incase these funds are insufficient, the
project faces a funding gap [5, 9]. The investors are not just financially motivated but
social reputation and intrinsic motives play a significant role. The motives of
participants in crowdfunding are different and may also depend on the model adopted.
Due to the rapid growth of social media, it is now identified as the key for the capital
providers to participate in crowdfunding platform [6]. Experimental results have also
shown that social media reduce most of the information asymmetries and hence,
enhance the possibility of funding. The existence of such a platform serves as a major
advantage for both investors and initiators. In order to provide a standardized process,
the platform acts as an information, communication and secure portal [7, 8].
The system proposed is secure as the transactions are captured onto the
blockchain. The venture is termed as successful if the initiated project collects the
designated amount in the stipulated time else it will be deemed as a failure and
through backtracking process, the money will be returned to the investors. Before
initiating the project, the necessary documents are furnished and on successful
verification, the project is launched. Thus making it secure and transparent to the
investors.
This paper provides an insight into the existing platforms in crowdfunding and the
updated proposed system making the platform safe, secure and more transparent. The
focus of our study lies in the decentralized approach to the existing system. The
research work is done on this platform with an aim to eliminate the middle-man and to
reduce the swindling activities in this domain. Through approaches like the
aforementioned, startups will get more opportunities and a better platform to build and
capitalize on the market.
In the next section, we will discuss the literature survey done in this field. Section
3.0 deals with the background and existing system. Section 4.0 deals with the
terminology used in the project. Section 5.0 deals with case study analysis. Section 6.0
deals with result analysis followed by conclusion and references.
2. Literature Survey
Agrawal, A. [1] et.al proposed research work based on geographic location, the
influence of social media and time to fund the project and analysis on it. This also
gives an overview of the financial aspects involved in crowdfunding platform and
their transactions. Ahlers [2] et.al proposed their work on the equity crowdfunding
7
platform in increasing its performance and providing equal shares to the investor and
initiator of the project based on their ECP algorithm. Aitamurto T [3] et.al proposed
their work on the impact of crowdfunding platform on journalism and its practices
which showed a new model of approach to the existing system. Davis B.C [5] et.al
proposed their work on examining the role of intrinsic versus extrinsic cues.
Entrepreneurship Theory and Practice based on the funding issues faced in the initial
process of beginning the company. Quercia [6] et.al proposed a system for the
investors by building a recommender system so that the investors are guided about the
project so that they get maximum shares for the funds they invested. The
recommender system takes into account the past and present scenario of the project
and its details for recommending. Ashta [7] et.al carried an analysis of the investors
investing in crowdfunding projects on European online micro-lending website and
found that the funds were more to Innovative marketing projects. Mahagaonker [8]
et.al proposed a financial signaling system which used to send updates to the investors
regarding a new project in the crowdfunding platform which is innovative and more
profitable. Bachmann [11] et.al proposed a literature review on Online peer-to-peer
lending system and the working of internet banking and commerce in the centralized
architecture. Hekman [14] et.al proposed Social network analysis on the relationship
between the success of crowdfunding projects, social networks of initiators and media
activities.
3.Background and Existing System
Of late the term crowdfunding has got a lot of steam. This is due to the huge
number of online campaigns to raise money for various causes. In simple terms, this
could be interpreted as an individual or a group introduces a notion or situation that
may require financial support. At the core, these benefits startups, personal projects,
etc the most. However, there is a lot of uncertainty encircling it.
They opt for this kind of a system for varied reasons ranging from a natural
calamity to help people for their work or projects. Big companies like paytm,
facebook, etc have stepped into this field and thereby provide a platform for donating
money for a noble cause. But the biggest question that surrounds this is that nobody
knows whether the money donated is reaching the needy or is being manipulated at
some point.
To mitigate this, Blockchain Technology can be used as once the transaction
details are stored on a block it cannot be altered. If anyone tries to change even a small
character immediately the hash value changes due to the avalanche effect and hence
indicating that the data has been manipulated. This provides high security of data and
eliminates the manipulation of information. Moreover, the investor can keep track by
using the hash value generated when the transaction details are mined into a block as
data. The advantages of this kind of system are it is more transparent, secure and
manual errors are eliminated.

4.Related Terminologies
Blockchain is one of the booming words in the field of Computer Technology,
which has the power to change the lives of people as the Internet did in the past twenty
years. It is ready to make a big impact on the lives of people if we adhere to this
technology. As it is a tech-savvy concept containing many technical terms, some of
them which are required to understand are listed below
4.1 Blockchain
Blockchain can be best described as an expanding list of records called blocks,
linked and stored using cryptography. The primary block is attributed as the genesis
block. All blocks will have the succeeding details in it:
1) Data: String of characters stored.
2) Nonce: A unique number related to mining.
3) Previous Hash: Hash value of a block that came before the current block.
This field establishes the cryptographic link with the following block.
4) Hash: Fingerprint for the data stored in the block.
4.2 Ethereum
Ethereum is a dynamic, decentralized, open-source service that operates on the
characteristics of the blockchain. It was originally proposed in 2013 through a white
paper by Vitalik Buterin. This was obtained from the bitcoin project which is
fundamentally a tool intended towards monitoring transactions among people. The
essence of ethereum gyrates around smart contracts. These are small blocks of code
residing in the blockchain intended to perform a specific task. Ethereum can be
described through the following:
1) Ethereum Network
The base of a decentralized network is made up of an assortment of nodes
interacting with each other. This is largely associated with the transfer of money and
storage of data, achieved through a cryptocurrency called ether. Ether is very much
similar to bitcoin and is accountable for fueling the ethereum network.
2) Interfacing with Ethereum
Interfacing refers to the process of interacting with the network. This can be
accomplished in 2 ways:
a) Web3 library: It is an API predominantly used by the developers to
interact with the network.
b) Metamask: It is a browser extension used by users to interface with the
network. 3) Ethereum Account
An ethereum account will have the following basic elements:
a) Balance: The number of ethers owned by this address.
9
b) Nonce: It depicts the number of transactions carried out from a specific
account address or illustrates the number of contracts produced by the
account.
c) CodeHash: Hash code of the EVM of this account.
d) StorageRoot: A 256-bit value representing the encoded version of the
data stored in the chain.
4.3 Dapp
Dapp is an open-source application that works totally on the smart contract code
running on the blockchain. These have been designed in such a way that, it is not
controlled by any single entity but rather regulated by blocks of code known as smart
contracts. DApps uses decentralized storage to store data and code. The
aforementioned is a blockchain-based app, where the Smart Contract is employed to
connect to the blockchain[15].
5.Mathematical Analysis
The main objective of the below-mentioned algorithm is to protect our system
from all failures. This works on the consensus protocol. All the nodes in the network,
c reate an indisputable system of understanding among various nodes in a distributed
network.
