This document provides an overview of blockchain technology and how it can be adopted by businesses. It begins with a flowchart to help determine if blockchain is suitable for a particular use case. It then discusses key components of blockchain architecture like participants, consensus mechanisms, and data security. The document outlines different types of blockchain networks and considerations for choosing a private, consortium, or public network. It concludes with criteria for selecting the right blockchain platform, such as licensing, compatibility, community support, and scalability.

Enterprises
ADOPTING BLOCKCHAIN FOR BETTER BUSINESS OPERATIONS

2. Overview
Purpose
Created to highlight advantages of
private blockchain over centralized
databases and public BCs.
Audience
• Top business management (Non-Tech)
interested in creating POC for their
business
• Anyone looking to get started In
blockchain ecosystem
Intended Use
• Making decision about architecture
best suited for your business .

3. Is Blockchain Required ?
Blockchain cannot solve all problems in the world. Make your project pass through this
flowchart to know whether blockchain can provide solution to business or not.
Need to share data across multiple
Participants
(Departments/Organizations) ?
All participants can trust your
IT system ?
Need for strong audit trail ?
Is data sensitive enough to be
immutable ?
Need for shared history and
visibility for all parties ?
Yes
NO
Valid Blockchain Use-Case
Blockchain won’t be the
best solution
NO
Develop a system and give API
access to each participants
Is shared database acceptable ?
Is centralized ledger acceptable ?
Yes
NO Yes
No
NO

5. Blockchain – In Brief
• Account book in which
business transactions
are recorded
sequentially
• This book is not
controlled and
maintained by any
central authority.
Shared Ledger
• Collection of
information in such a
way that it can be
updated /deleted only
through set of rules
embedded in design of
the application.
• This makes blockchain
trustless as all server-
client applications are
Immutable
Database
• Information recorded is
translated into a form
that is easy to move
around
Data
Transferring
• Information recorded
can be accessed by only
someone who has
permission i.e Public
Blockchain (by anyone) ,
Private Blockchain (only
with peers)
Secure

6. Components In Blockchain Architecture
•Dependent on code
written in Smart
Contract of the
Application
•That’s done through
Cryptographic Elements
in place
•Decided by Consensus
Mechanism chosen
•Decided by type of
blockchain Network
chosen

7. Work flow in Blockchain
Transaction
Request
• “Transaction” is requested by one of the participants in the network i.e NODE
• This transaction is broadcasted to P2P network of Nodes
Transaction
Validation
• Network of nodes(participants) validate the transaction and user state.
• Validation is done using Validation Algorithm e.g. Public Key Cryptography
Block Creation
• “Verified Transaction”(Cryptocurrency, Record, Contracts) are linked with other verified transactions.
• This chain of verified transaction creates new “Block” of data for blockchain
Block Validation
• New block of data is validated through “Consensus Mechanism” used by the network e.g. Proof of work.
• Verified block is added to existing blockchain data in an Permanent and Immutable way.
Transaction
Completion
• TA –DA Transaction completed successfully ;)

9. Blockchain Networks
Consortium Network
Consensus process is controlled by a pre-selected set of nodes(Participants). The right to read
the blockchain may be or restricted to the participants.
Semi – Private Network
Single company grants access to any user who qualifies, to read and write on the network
Private Network
Write permissions are kept to one organization. Read permissions may be public or restricted
to certain participants.
Public Network
Anyone in the world can read, send transactions and anyone can participate in
the consensus process

10. Choosing Right Network
Private Semi-Private Public
Privacy of data High – Only
permissioned uses and
read write
High – Only
permissioned users and
read write
None -- Anyone can
Read and Write
Governance Totally in the control of
owner
Totally in the control of
owner
Owner has no control
Innovation Target Process within existing
relationships.
Supporting existing
model or creating new
services
New business model
Number of Users Dozen to few hundred Hundred of thousands Millions
Setup Cost High High Low
Operational Cost Low Low High
Platforms Hyperledger, Multichain Quorum, Corda Ethereum, NEO

11. Choosing Right Blockchain
Platforms
License - Check It is necessary to know whether the
framework is free to use or if it comes
with a paid service as it would impact
your overall costing.
Compatibility Check whether platform can smoothly
integrated with the existing business
systems or not
Community Support Sufficient amount of community is
required in development and
production as it true any enterprise
software. Check for adequate
community support for platform that
you have chosen
Scalability Network congestion could become
major roadblock so choose platform
that promises high scalability and
efficiency of transactions
The proliferation of blockchain
technology has led to the availability of
various blockchain based solutions for
enterprises. Consider these criteas while
choosing right platform for your
business
