Blockchain Fundamentals
What exactly is Blockchain technology?

What Exactly is Blockchain Technology
What is a Blockchain?
• A cryptographically secure, shared, distributed ledger.
• Immutable transactions are written on this distributed ledger on distributed nodes
• Transformational technology in which business and government invest in.
• It’s a decentralized database which stores information in the form of transactions.

A Blockchain essentially is a record of transactions similar
to a traditional ledger. These transactions can be recorded
for anything and not just financial
• Blockchain is NOT Bitcoin
• Blockchain is NOT just about Cryptocurrency
• Blockchain is to Bitcoin, what the internet is to email

A distributed ledger is a database that is stored and updated
independently by each or node in the blockchain.
• The decentralized and distributed nature is what makes it
unique.
• In blockchain they are immutable
• Every single node on the network processes every
transaction that occurs.

What is a Cryptocurrency?
• Digital currencies are secured using cryptography and
combining that with their role as a currency.
• Are mined. Not printed.
• Considered digital gold, silver..
• Bitcoin is the most widely known and has the largest
market cap.

Lets Discuss Bitcoin Briefly
• Bitcoin(BTC) was created by a discrete creator
named Satoshi Nakamoto in 2009. To this day no
one knows who he or she is.
• Bitcoin now has a fork called Bitcoin Cash.
• Bitcoin is known as “crypto gold”

Blockchain is evolving
• Bitcoin was released in Jan 2009 by Satoshi Nakamoto
• Blockchain technology then enabled cryptocurrencies, inspired by distributed ledgers,
asymmetric encryption and Merkle trees technologies
• Altcoins for specific use cases = Dogecoin, Ethereum, etc (2011-2017)
• Enterprises explore potential benefits of the technology (Hyperledger, Corda and
Quorum)

Built from these technologies.
• P2P Networks
• Private Key Encryption
• Programs

Digital Identity is established
• Combining a public and private key creates a
strong digital identity reference based on
possession.
• Private Key
• Public Key

Blockchain is revolutionary in several ways
• Blockchain is not new technology but a synching of
technologies that now make sense.
• Trust is at the center and essentially removes
intermediaries. (efficiency)
• Tamperproof public ledger of value.
• Disruptive to the status quo. Legacy is out
• Platform with numerous use cases

Transactions in Blockchain
• In a Blockchain for a transaction to be considered valid, it will be processed by a
validation process known as blockchain mining.
• Mining is when a group of nodes use their computing resources to create a block of
valid transactions.

Smart Contracts
Smart Contract is a term to describe computer program code that is capable of facilitating,
executing, and enforcing the negotiation or performance of an agreement using Blockchain
technology. (Contract)
• The entire process is automated and can act as a complement or substitute for legal
contracts.
• Terms of the smart contract are recorded in a computer language as a set of instructions.

Smart Contracts
Smart Contracts
• Smart contracts define the rules and penalties
around an agreement in the same way that a
traditional contract does
• Automatically enforce those obligations
• Several smart contracts can make up a dApp
generally

Why are companies are embracing Blockchain technologies?

Blockchain and Change
• Enterprises require innovation
• Enterprises require efficiencies
• Enterprises must adapt or fail
• Provides new market opportunities
• Adapt to ever changing business needs
• Meet Compliance demands

• Some Blockchain Humor

• In PwC’s 2018 survey of 600 executives from 15
territories, 84% say their organizations have at least
some involvement with blockchain technology.

• The business value-add of blockchain will grow to
slightly more than $176 billion by 2025, and then it will
exceed $3.1 trillion by 2030.

Overview of major Enterprise Blockchains

Enterprise Blockchains
Lets Discuss the most common smart contract enterprise blockchains

Ethereum
• Most widely used Open Source Blockchain-based distributed
computing application platform
• Mainly used for building & implementing smart contracts
functionality
• It offers a Decentralized Virtual Machine aka Ethereum Virtual
Machine (EVM)
• Initiated by Vitalik Buterin in 2013
• Ethereum's live Blockchain was launched on 30 July 2015

Ethereum
• Ether is the native token of the Ethereum blockchain which is used
to pay for transaction fees, miner rewards, and other services on
the network.
• Ethereum is an open software platform based on blockchain
technology that enables developers to write smart contracts and
build and deploy decentralized applications.

Hyperledger
• Hyperledger is an open source project that came out
of the Linux Foundation and was created in order to
help advance cross-industry blockchain technologies.
• It is essentially a global open source collaboration
involving leaders from numerous industries.

Hyperledger Blockchains
The Framework Module includes
• Hyperledger Indy
• Hyperledger Fabric
• Hyperledger Iroha
• Hyperledger Sawtooth
• Hyperledger Burrow

R3 Corda
• R3 is an enterprise blockchain software firm working with a broad
ecosystem of more than 200 members and partners across multiple
industries from both the private and public sectors to develop on
Corda, our open-source blockchain platform, and Corda Enterprise, a
commercial version for enterprise usage.
• Corda removes costly friction in business transactions by enabling
institutions to transact directly using smart contracts, while ensuring
the highest levels of privacy and security.

R3 Corda
• R3 Corda aka “Corda” and was developed in 2016
• Corda was first built to record, manage and automate
financial agreements.
• Corda was developed specifically for banks with some
limited use cases outside of that area.

Quorum
• Quorum is ideal for any application requiring high speed and high
throughput processing of private transactions within
a permissioned group of known participants.
• Quorum addresses specific challenges to blockchain technology
adoption within the financial industry, and beyond.
• Quorum was built on the Ethereum Platform and sponsored by
JPMorgan Chase

Quorum
• Quorum is an Ethereum side chain
• Quorum has benefits over Ethereum
such as Privacy and Consensus Choices.
• Quorum supports two distinct Consensus
Algos RAFT and IBFT

Transactions Per Second (TPS)
