Smart contracts are the next version of automated contracts where the user won't have to rely on trust. Smart contracts are automated algorithmic digital forms of contracts where parties can exchange assets without any intermediaries based on specified rules. Here, the program within the smart contract will self-execute based on the conditions previously defined by the parties.
There are certain benefits to using smart contracts such as autonomous, secured, interruption-free, trustless, cost-effective, fast performance, and accurate and error-free. But here, we will analyze the examples of smart contracts, such as how it can be useful in digital identity, supply chain management, insurance, etc.
To help you understand how smart contracts work or how you can utilize this new form of technology for your personal gain, or company 101 Blockchains offers an array of courses. You can use these courses to learn more about smart contracts and its role in various sectors.

Blockchain Digital Transformation Presentation101 Blockchains
Blockchain is transforming the world around us. And, there is no doubt that it is going to change how we interact with each other. In this powerpoint presentation, we will be looking at blockchain digital transformation. The blockchain powerpoint presentation is aimed at both new and experienced learners. If you are looking for the ultimate digital transformation blockchain ppt, you have come to the right place.
The blockchain ppt covers all the necessary things that a beginner should know about digital transformation, but also ensure that it covers more exciting topics related to the topic. For example, the second blockchain powerpoint slide covers the subject, “Public vs. Private.” This is essential to understanding the fundamental need for a decentralized network, i.e., blockchain. We also include the key features that power the digital world through blockchain.
Blockchain is, as The Economist (2015) calls it, "a trust machine".
To let the readers understand the need for blockchain and its improvement over the year, we have also covered the history of blockchain transformation. The history of blockchain is vibrant including the release of permissioned frameworks such as HyperLedger and R3. Other distributed ledger technology also flourished from 2009 to 2019. We have covered most of the important ones in the blockchain ppt.
Different use cases along with their implementation challenges have also been covered to give you a glimpse of how the current blockchain technology is shaping and impacting other industries out there.
Another important thing that we covered includes how non-financial enterprises are adopting blockchain. There are companies such as Ford and Toyota that are working round the clock to implement blockchain in their smart mobility solutions. Even insurance giants like Prudential and Metlife are automating a lot of the insurance processes using blockchain. To power these financial and non-financial institutions, federated networks are been used. They are permissioned frameworks that empower business and ensure that they get all the tools to make a blockchain network according to their needs and requirements.
The enterprise blockchain ecosystem is also strong, thanks to the players such as Ethereum, Hyperledger, and Corda. Hundreds of enterprises are utilizing Hyperledger. Two key examples include the T-Mobile and London Stock Exchange Group.
Apart from the big enterprises, the healthcare industry also seems to be interested in the blockchain. They are using it to save lives and improve the state of the healthcare industry.

Decentralized applications 101: How and why to build a DAppErik Trautman
You're already well familiar with the design, interaction and development patterns of "normal" web and mobile apps. In this meetup, we'll shift the focus to describe what a decentralized app (DApp) actually is from the very top to the nuts and bolts below the surface.
This is intended to help the full spectrum of designers, developers and product people to understand why they might create a DApp in the first place and how that is different than working with web 2 applications. We'll cover the high level user-facing aspects (like interactions and flows) down to the low-level of the stack (the actual blockchain) so you understand what you're getting into.
We assume you know what a blockchain is.

This presentation on smart contract tutorial will help you understand what is a smart contract, why we need a smart contract, solidity for a smart contract, Blockchain implementation of the smart contract, voting process, hospitals and at the end you will see a use case implementation on crowdfunding smart contract. Smart contracts are self-executing contracts which contain the terms and conditions of an agreement between the peers. A smart contract is very similar to a vending machine. It eliminates the need for intermediate and escrow services. The terms and conditions of an agreement are written in code. These agreements facilitate the exchange of money, shares, property etc. All of this process is executed in Blockchain's decentralized platform. So, let us get started and understand what is a smart contract.
Below topics are explained in this smart contract presentation:
1. Why smart contract?
2. What is a smart contract?
3. Solidity for smart contract
4. Blockchain implementation of a smart contract
5. Voting process

Introduction to Ethereum Blockchain & Smart ContractThanh Nguyen
The Harvard Business Review (HBR) thinks that Blockchain Technology has to power to keep data safe for consumers and businesses alike; because Blockchain provides a secure and immutable ledger, HBR says it represents the key to taking back privacy of data.
“You can keep certified copies of identity documents, biometric test results, health data, or academic and training certificates online, available at all times, yet safe unless you give away your key. At a whole system level, the database is very secure.”
The Defiant YouTube's Robin Schmidt created a DeFi 101 presentation explaining what this new blockchain-based financial freedom is all about. You'll get the definitions you need to talk the talk, the protocols to get you started and the data sources to not get rekt.
Basic introduction in blockchain, smart contracts, permissioned ledgersKoen Vingerhoets
Presented during Blockchain Vlaanderen #7 on 20/04/2017, organised by Kunstmaan and Antwerp Management School.
The assignment: host a basic introduction into blockchain, share some insights on smart contracts and explain why financial institutions choose other ledgers than bitcoin.
Smart Contracts are a central component to next-generation blockchain platforms. Blockchain technology is much broader than just bitcoin. The sustained levels of robust security achieved by public cryptocurrencies have demonstrated to the world that this new wave of blockchain technologies can provide efficiencies and intangible technological benefits very similar to what the internet has done.
Blockchains are a very powerful technology, capable of going much further than only "simple" financial transaction; a technology capable of performing complex operations, capable of understanding much more than just how many bitcoins one currently has in his digital wallet.
This is where the idea of Smart Contracts come in. Smart Contracts are in the process of becoming a cornerstone for enterprise blockchain applications and will likely become one of the pillars of blockchain technology.
In this presentation, we will explore what a smart contract is, how it works, and how it is being used.

Blockchain Ecosystem and Cryptocurrency RegulationsAmir Rafati
A blockchain is a general digital ledger of transactions that are executed on the network, e.g. using Bitcoin to buy a cup of coffee is a transaction.
All users of the network, ‘Nodes’, have a copy of the transaction records and can access them freely, a role previously played by centralized institutions. Therefore, the blockchain network is ‘decentralized’.
An evaluation of Ethereum technology. The weakness and the strength of this new blockchain technology. It includes also a comparison between Ethereum and Bitcoin.

Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
2. The Blockchain
ethereum
■ In 2008, Bitcoin was launched as a peer-to-peer
database that relied on a new data structure
referred to as the ‘blockchain’.
■ The blockchain consists of blocks, where each
block holds a set of transactions and a
reference to the previous block. This helped
create a chain of all transactions that ever
occurred.
■ This data structure is replicated across all
participating nodes so that every participant is
aware of the transactions without having to get
them from a central authority.

3. Distributed Consensus
ethereum
■ In order to control how new blocks (with new
transactions) are added to the chain, the
design relies on a consensus mechanism
which requires anyone (a node in the peer to
peer network) who would like to nominate a
new block (with new transactions it has
gathered from its peers) to solve a puzzle that
requires significant computations (computer
processing power). The difficulty of this puzzle
is dynamically adjusted such that it takes on
average 10 minutes for any one node to solve
the puzzle. A process known as mining.
■ Whenever a node solves the puzzle and create
the new block (which includes new
transactions that it has gathered from other
peers around it), the node is rewarded with an
amount of new Bitcoins which it can use to pay
for the cost of solving the puzzle (computer
equipment and electricity).

4. Decentralization
ethereum
■ Given the architecture of the blockchain, the
database continues to grow so long as nodes
keep trying to nominate and verify new blocks
regardless of nodes joining or leaving the
network
■ The fact that the entire database exists without
depending on a single node, makes it very
powerful and almost impossible to alter or
destroy (the decentralized feature of the
blockchain)
■ The integrity/validity of transactions in the
block chain is ensured through the use of
cryptographic techniques that make it efficient
to verify if any invalid transactions have been
added

5. Beyond Bitcoin
ethereum
■ The architecture of the blockchain is very
powerful as it enables decentralization while
maintaining security. This has significant
implications on the design of computer systems
as it allows computer applications to be scalable
and reduce the requirement for a large central
infrastructure
■ While the first successful use of the blockchain
database architecture was demonstrated on the
Bitcoin network, many started exploring how
they can utilize this design for other transactions
beyond value transfer transactions which Bitcoin
mainly handles

6. Towards a Peer to Peer Computing Framework
ethereum
■ While, the design of the blockchain solved
many issues when it comes to decentralizing
and securing transactions. There was no easy
way to specify logic that made use of that
database for purposes beyond the transfer of
value between accounts.
■ The Ethereum project set out to design the
required pieces to evolve the blockchain from a
distributed transactional database to be part of
a general purpose peer to peer computing
framework.
■ At the heart of ethereum is a virtual machine
capable of executing instructions known as the
Ethereum Virtual Machine (EVM), it allows the
execution of programmed instructions stored
within the blockchain

The Blockchain of State and Transactions
ethereum
■ To introduce the ability to execute programs,
the blockchain was modified such that each
block not only contains the latest transactions
but also the latest state of member programs
(aka., contracts).
■ With every new block the state of contracts in
the blockchain is updated per the processed
transactions thereby taking the blockchain to a
new state.
■ As a mean to ensure that provided instructions
do not run forever, a constraint is built into the
execution of every contract so that any party
invoking a contract in a transaction is required
to provide special tokens of monetary value
that get consumed depending on the number
of instructions and the storage used by the
contract.
ethereum
8. Contracts as Accounts
ethereum
■ A contract has a permanent address on the
blockchain which gets assigned when it is
created. This permanent address is used to
identify the contract.
■ Every contract contains a balance of the basic
monetary unit in the ethereum network referred
to as ether.
■ If a contract does not include any programmed
instructions, it behaves as an account. It has an
address and a balance. This account can
receive/send ethers from/to other
accounts/contracts.
Address
Balance
ethereum
9. Contracts as Decentralized Executable Programs
ethereum
■ Ether is required to call a contract, this is done
to ensure that infinite execution does not occur
as the execution stops the moment the ether
amount sent along with the call is consumed
■ When a contract is called, a small amount of
ether is required to be sent along with the call.
This amount is eventually transferred to the
node that gets to nominate the next block in the
block chain. However, when a contract is called,
an amount of ether can be directly transferred
to that contract there by instituting a balance
transfer like in the case of a payment
■ When referring to the calling of a contract, it is
in reference to invoking one of the methods in
the programmed instructions which can be
used to execute a certain action

10. Contracts as Decentralized Executable Programs
ethereum
■ The execution of a method can modify the state
of the contract by manipulating one or more of
its fields
■ A contract can also have set of events which
are used to notify interested parties of the
occurrence of certain events during the lifetime
of the contract
■ A contract lives forever on the blockchain once
it is created unless, the original instructions
made use of the suicide feature, a feature which
destroys a contract and transfers its ether
balance to another account

11. Messaging and File Sharing...
ethereum
ethereum
swarm whisper
■ In addition to the use of the ethereum virtual
machine to execute contract logic. The
ethereum project also introduced two
additional protocols to provide peer to peer
support for exchanging message as well
exchanging static files
■ The peer to peer protocol used for exchanging
message is named whisper and it provides a
powerful distributed and private messaging
capabilities with support for single cast,
multicast and broadcast messages
■ The peer to peer protocol used for exchanging
static files is named swarm and it provides a
new incentivized approach to distribute static
content among peers and exchange them
efficiently
ethereum
12. Decentralized Messaging
ethereum
■ Whisper provides a peer to peer protocol for
exchanging short timed messages privately
■ Whisper relies on a subject key (Topic)
approach to deliver messages where messages
are published using a hashed topic
■ Messages can be encrypted with a specific key
for privacy
■ Indirectly supports broadcast, multicast and
unicast
■ Whisper is a high latency and low bandwidth
messaging protocol
■ Provides the ability to use masks/filters to
narrow down topics of interest without giving
away what topic is being sought
■

ethereum
13. Incentivized File Transfer ...
ethereum
swarm
■ Leverages the underlying ethereum
infrastructure through the use of a contracts
and ethers to encourage cooperation among
nodes
■ Files are split into chunks which are stored in
nodes in the network
■ An accounting protocol is used by peers to keep
track of chunks delivered and received and
resulting micro-payments owed
ethereum
14. DEMO
ethereum
■ Assume we would like to create a smart door
which opens up if given the right key.
■ Adding a new user required two or more users to
authenticate the transaction.
