Blockchain technology provides a peer-to-peer transaction system without a central intermediary by using a distributed ledger called a blockchain. The document discusses how traditional transactions rely on centralized parties like banks and payment processors to facilitate transactions and provide trust, whereas blockchain transactions use cryptographic techniques and distributed consensus to validate transactions without intermediaries. The blockchain grows over time as new blocks of transactions are added through a decentralized mining process, linking each new block to previous ones in an immutable chain. This allows for fast, global, low-cost transactions without centralized control.
Blockchain technology can revolutionise the provision of decentralised Applications Dapps, as well as help IoT systems to boot to reduce the cost of this development, the stakeholders to determine how to distribute benefits and take into account five basic principles:
• Potential effects of technology on IoT systems
• Organisational changes
• Secure the correct data
• Financing electronic IoT systems
• Security and privacy of user data

There are many cryptocurrencies out there; in fact, as of April 2021, there were over 9,500 cryptocurrencies in circulation listed on the Coinmarketcap. This number is expected to increase in the future as people’s interest in cryptocurrencies keeps rising. Although you might have heard about cryptocurrencies and known how it works, it’s possible you still don’t know what cryptocurrency actually is, or what means. The fields of cryptocurrency and the blockchain technology that drives cryptocurrencies can be a bit confusing. So, what is cryptocurrency? This article uses relatable terminology to explain in detail what cryptocurrency is, and the science of cryptography that decentralizes and drives cryptocurrencies, and makes them secure.

Introduction to blockchain and crypto currenciesRohas Nagpal
The Blockchain technology has received tremendous attention over the last couple of years.Key benefits of blockchains include immutability and decentralisation.
Reserve Bank of India has said that "With its potential to fight counterfeiting, the 'blockchain' is likely to bring about a major transformation in the functioning of financial markets, collateral identification (land records for instance) and payments system".
This presentation introduces the blockchain technology.
Overview of what is Bitcoin, Ethereum, Smart Contract and Blockchain.
First explained what is Bitcoin and its entities involved. Then Ethereum and what is called Blockchain.
Examples of the existing platforms those are using Ethereum.
How Blockchain and Cryptocurrency works.Waleed Ahmed
A blockchain is a way of storing data so that cannot be changed anymore. This is called immutability and a very useful feature when dealing with very important data like bank records or transactions.
This presentation will teach you the simplest methodology of how blockchain works.
Block chain and Bitcoin. A blockchain is a data structure that makes it possible to create a digital ledger of transactions and share it among a distributed network of computers.
With the recent crypto bubble engulfing the world, you would have come across two prominent words: Blockchain and Cryptocurrency. Well, when it comes to origin and development then cryptocurrency marks the growth of Blockchain technology.
I have been presenting blockchain and bitcoin to several companies and audiences in the past 2 years (mostly financial companies).
I started taking notes of their questions as it allows me to reconstruct their thought process while they discover and familiarize themselves with the concepts. These slides have been prepared for investment fund based in Luxembourg. I worked with the Head of Market Research to make the presentation tailored to their needs. Although we tried not to abuse simplifications, we had to gloss over many details and use analogies.
The team was particularly interested in the ecosystems and applications.
Here are the questions I could write down or remember, in their order. Hopefully they will help someone giving similar presentations to similar audiences.
+ Where is actually the blockchain?
+ Do I need all the blocks?
+ How big is it? If the data keeps adding one day it would take *hours* to download
+ In a peer to peer network how are people discovered?
+ Are there people checking all the blocks to verify the transactions? Could i do it?
+ Why do miners would want to do work to validate transactions?
+ Could I mine myself? How?
+ Why am i not mining if i can make 12.5 btc?
+ When does the blockchain ends?
+ What does prevent people from using bitcoin for illegal activities?
+ How could governemnts block it? How can it be shutdown
+ How can transactions be traced? Is it anonymous?
+ Where is the mempool?
+ What prevents everyone to do his own coin?
+ Where does it start? What happens if Satoshi sells its coins? + How was the 21M coins cap decided? Who decided it? Can it be changed?
+ Does the protocol evolve? who modifies it? what happens if some people don't want the modification.
+ If second layers protocols arrive (Lighting) would miners still be required?
+ What is difficulty and why 10minutes per block? Who decides how difficulty is updated? Based on what?
+ Can i do my ICO? How is it done?.
+ Is it legal? How is the crypto business legally recognised.
+ Which countries are more open to blockchain
+ How will governements tax it?

Ask for assistance. Gnashing your teeth in the dark will not get you extra brownie points. It is a sign of strength to ask for assistance and people will respect you for it.
I spent quite some time to digest how Blockchain works and how it can influence our everyday life in the upcoming decades. My slides focus on that from a non-IT expert point view.

Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.

Launch Your Streaming Platforms in MinutesRoshan Dwivedi
The claim of launching a streaming platform in minutes might be a bit of an exaggeration, but there are services that can significantly streamline the process. Here's a breakdown:
Pros of Speedy Streaming Platform Launch Services:
No coding required: These services often use drag-and-drop interfaces or pre-built templates, eliminating the need for programming knowledge.
Faster setup: Compared to building from scratch, these platforms can get you up and running much quicker.
All-in-one solutions: Many services offer features like content management systems (CMS), video players, and monetization tools, reducing the need for multiple integrations.
Things to Consider:
Limited customization: These platforms may offer less flexibility in design and functionality compared to custom-built solutions.
Scalability: As your audience grows, you might need to upgrade to a more robust platform or encounter limitations with the "quick launch" option.
Features: Carefully evaluate which features are included and if they meet your specific needs (e.g., live streaming, subscription options).
Examples of Services for Launching Streaming Platforms:
Muvi [muvi com]
Uscreen [usencreen tv]
Alternatives to Consider:
Existing Streaming platforms: Platforms like YouTube or Twitch might be suitable for basic streaming needs, though monetization options might be limited.
Custom Development: While more time-consuming, custom development offers the most control and flexibility for your platform.
Overall, launching a streaming platform in minutes might not be entirely realistic, but these services can significantly speed up the process compared to building from scratch. Carefully consider your needs and budget when choosing the best option for you.

2. Cash is peer to peer
Observations:
➔ No middleman required.
➔ DIY Fraud detection
➔ Sufficient trust for the value of the
transaction
➔ Anonymous/Private
➔ Distributed
3. Electronic Middlemen
Observations:
➔ Requires 3 rd
party trust
➔ The more complex the flow, the
more middlemen required
➔ Specialised equipment needed
(e.g. POS terminal, connection to
Txn networks
➔ Fraud detection by 3 rd
parties
➔ Every step adds cost
Electronic Middlemen
4. Middlemen adding value
➔ Provision of infrastructure (Terminals, network connections etc)
➔ Management of commercial relationships between parties (Lots of
lawyers)
➔ Abstraction of complexity
➔ Fraud detection
➔ Customer service
➔ Regulatory compliance KYC, AML, Risk reporting
➔ Removal of bad-actors from the ecosystem
Until now, this is the best way we’ve been able to achieve the goal
of person-to-person transactions at a distance.
5. Transaction volumes are growing
Now:
➔ Online banking transaction growth
➔ SME’s/Retail acceptance of electronic
transactions
➔ Online purchases/Commerce
➔ In-App purchases
➔ Virtual currencies in games
➔ International Transaction growth
(Commerce and Remittance)
➔ Value storage cards (loyalty cards, ERP,
gift cards etc etc)
Future:
➔ Internet of Things
➔ Autonomous Objects
➔ Programmable
money/Finance automation
6. Limitations of cash
Can be used locally only, global reach is limited
Electronic funds transfer (ETF) requires Debit/Credit Card
High fees for merchants
Slow settlement
Micro transactions not possible
Controlled and governed by central authority with no hard cap.
Arbitrary limits on local and international transfers on timely basis
Accounts can be freezed
Minimum balance required in most cases for bank accounts
Not fungible
More probability for hacking as there is a single point of authority
7. Advantages Blockchain powered payment networks (Bitcoin)
No centralized authority or middlemen -
its not controlled or governed by a any authority or governement
No arbitrary limits and fungible -
No daily limits which banks impose whether a domestic or
international transfers, any amount can be moved
No freezing of accounts – paypal is notorious for this
No charge back – paypal again was notorious for this
No fees for merchants –
it costs nothing for merchant to accept bitcoin, no middleman and
bureaucracy, no need of paying credit fees.
8.
Faster than internation bank trasnfers -
Instead of waiting for 2-5 business days, Bitcoin lowers this
down to an hour (hopefully less with lightning network).
Bonus – no FX fees either.
No government printing money -
The government can’t decide to inflate and devalue your
currency.
Limited supply -
Only 21 Million coins are available
Open and transparent -
Its free and open source anyone can verify its credibility by
checking its source code.
Global reach -
Wherever there’s internet, Bitcoin is possible. If there’s a
disaster all the way across the world and you feel like
donating, you can.
Advantages Blockchain powered payment networks (Bitcoin)
9.
Immutable in nature -
Transactions once recorded cannot be altered hence not
possible to make fraud.
No need for special equipment.
Provide pseudo anonymity
Advantages Blockchain powered payment networks (Bitcoin)
12. Key historical dates
➔ 2009 first block created
➔ Satoshi Nakamoto was the pseudonym used
➔ Satoshi disappears December 2010 - date of last post
13. Seeking Satoshi
While conspiracy theories are fun, it's mostly irrelevant
➔ Operational design published openly
➔ Protocol is opensource
➔ Code is opensource and has mostly been re-written
15. What is blockchain?
Blockchain is a distributed database system that acts as an “open ledger” ,
Its replicated across several computers assembled in a peer-to-peer network
which is spread across globe collectively following protocol for validating new
blocks
It contains continuosly growing list of records called blocks, which are linked and
secured using cryptography.
each block typically contains a hash pointer as a link to previous block with
append only property.
18. Blockchains
0 21 43 5
➔ Blocks are numbered in ascending order, 0 is first/oldest
➔ The number is the ‘height’ of the block
➔ Arrows only go from newer to older blocks - a block only directly links to
the one immediately before it
➔ Once a block is stored, it’s read-only (which is why it doesn’t link to the
ones after it - that would require you to update it)
19. Blockchains
0 21 43 5
➔ Blocks store data, in Bitcoin, it’s the transactions, but it could be any
digital data
➔ Blocks are created periodically (on average, 10mins for Bitcoin) by a
process called ‘mining’
➔ A block represents a set of events that have occurred over a particular
time frame (usually, since the previous block)
32. Distributed Networks
➔ Many, equal nodes
➔ Each node has multiple connections to other nodes
➔ Very resilient to failures, attacks
➔ As long as 2 nodes are up, the network is still running
33. Distributed consensus
Blockchain is a decentralized system with no single authority to trust, but maintains a commonly
agreed state between all the nodes in the network.
This common state is maintained via a distributed consensus.
Each blockchain has its own distributed consensus algorithm, which denies who can write to the
blockchain, and what rules to be followed and the rules for conflict resolution.
35. P2p network
blockchain implement their own p2p network to communicate between the nodes in network.
Once a transaction is verified by a node it broadcasts it to all the other nodes in the network,
and each node will independently verify.
A new node can join the network anytime.
Once one node hears about a bitcoin transaction, it validates it and then publishes it to all the
nodes its aware of.
The same thing will be repeated by all the nodes in the bitcoin network and ultimately all the
nodes in the bitcoin network will be aware of this transaction.
37. Blockchain is open and transparent
Transparency is ensured through the open, public decentralized ledger that anyone can view
Ex: blockexplorer.com
39. Trustless Trust
Encrypted transactions are initiated and accepted peer to peer.
There is no financial middleman or bank that establishes trust between the parties.
Instead, trust is established through the decentralized distributed ledger that is visible to anyone
within the network.
When a transaction is initiated, this worldwide network of computers race to validate the
transaction by solving complex algorithms. When the network reaches consensus that the digital
ledger reflects that the transferring party actually has the asset to transfer, the transaction is
validated and executed. And the digital ledger is updated, simultaneously, across the network.
Anyone with the necessary computer power can participate in the verification process
The network is able to validate, timestamp and clear a transaction instantly because that activity
happens immediately within the digital ledger itself, not between institutions.
41. Immutable
blockchain consists of blocks, where it starts with a genesis block, and each block since then,
links to the block prior to it.
Each block has it’s own hash and the hash of the block prior to it.
Each block has a set of transactions in it—and once written to the blockchain, it is hard to
change anything in the written block.
Since all the later blocks are linked to this block, if you are to change a block, you also need to
change all the other blocks written on top of it, till the very latest.
he distributed consensus algorithm (which we discuss in the next section) followed by each
blockchain implementation, makes this merely impossible both technically and economically.
42. Compare the ease and convenience of transferring digital
currency on the blockchain to the complexity of an ordinary credit
card transaction.
43. Comparision
Blockchain payment system
A wants to send money to B. The transaction
request is sent to every node in the worldwide
network
The network nodes validate that, according to
the digital ledger, whether A actually has the
money to send to B
If yes then transaction is approved and is
sealed into a secure block and the block is
linked to all previous blocks, forming an
immutable chain.
The money moves on the digital ledger from A
to B.
The transaction and settlement are
instantaneous.
Credit card transaction system
Customer pays with credit card
Merchant captures credit card information and
sends to the merchant’s bank
The merchant’s bank forwards the transaction
to the credit card company (VISA, Mastercard,
etc.)
The credit card company requests payment
authorization from the bank that issued the
credit card
The card-issuing bank approves the
transaction through the credit card company
and the merchant’s bank
Up to 48 hours later the transaction is posted
to the cardholder’s monthly statement by the
issuing bank and to the merchant’s statement
by the merchant’s bank
44. LOCAL ECONOMIES WORLDWIDE WILL RETAIN THE BENEFITS OF
THEIR LABOR
The largest flow of capital from the developed world to the developing world is
not foreign aid or corporate investment.
It’s the $600 billion sent home by emigrants in the form of remittances.
Currently that transfer of fiat currency goes though a middleman, be it a bank or
Western Union, charging anywhere from 5% to 25% in remittance fees
depending on where in the world the money is being sent.
And it takes several days to clear.
Imagine if that transfer were instant.
Imagine if it were peer-to-peer, with no middleman fees.
Goldman Sachs estimates that $100 billion annually could be saved and
plowed back into local economies.
45. SOCIETIES WORLDWIDE WILL BE SERVED BY MORE EFFICIENT
GOVERNMENTS
A significant number of governments around the world are applying blockchain technology to
solve their most pressing problems.
In Estonia, to combat healthcare fraud, the government has adopted blockchain technology to
secure one million health records, accelerating transparency and auditability.
The UK government’s Department of Work and Pensions is partnering with Barclays to use
the blockchain to distribute welfare payments, significantly
reducing waste and fraud.
The Republic of Georgia is piloting a blockchain land titling project. An estimated 70% of
people around the world who own land have tenuous title to it. Without a valid title, the land
can’t be borrowed against or sold. Documenting ownership of land, registering it as a
verifiable asset on the blockchain, opens up new value for the owners
Andhra pradesh and Telengana states of India are working on implementing blockchain for
land title projects

48. A national women’s fashion retailer is
struggling to update their image and become
a brand that matters among younger
Millennials. They’ve done their research
and carefully considered their customer’s
journey. They understand that younger
Millenial women favor brands that express
individuality and authenticity as well as
brands that have a positive social agenda,
brands that “do.”
So they’ve created a new line of scarves
sourced entirely with fabrics from Bhujodi,
India where the one-of-a-kind fabrics are
hand-loomed. So far, so good. The retailer
could tell this story across social and
traditional media and hope their customer
receives and believes the message.
to transparently prove their authenticity, to
connect with their audience from a single
source of immutable truth in order to build
trust and brand relevance.
The tag on each scarf carries the retailer’s
blockchain address whose immutable
records confirm Bhujodi as the origin of the
fabric and verifies that all-natural dyes were
used to create the fabric. Further, it validates
that the company of hand-loomers has a
reputation of employing their workers under
better than average conditions. Through the
blockchain, the product carries a transparent
extended brand narrative of authenticity and
trust directly to the Millennial consumer.
Moreover, knowing that “brands that do”
are important to Millennials, the retailer’s
marketing department has developed a
cause-related campaign to benefit Bhujodi.
The village’s electrical grid is unreliable and
frequently there are extended power outages.
The retailer has decided to donate up to 10
generators, based on the enthusiasm of its
customers to interact with its brand.
IMAGINE ESTABLISHING A BRAND
THAT MATTERS WITH THE BLOCKCHAIN
OR, THE RETAILER COULD PUT THE
BRAND INTO ACTION ON THE BLOCKCHAIN
49. Each time a customer interacts with the
retailer’s brand – through a purchase,
a social media share, interacting with
promotional materials – an agreed upon
Bitcoin micro-donation is made by the
company to the manufacturer. When the
total price of the generators is aggregated
and verified through the smart contract, the
funds are released to the manufacturer who
automatically ships the generators directly
to Bhujodi.
The trail of donations and the progress
against objectives is fully transparent
to customers on the blockchain. Their
actions are advancing a cause. And the
retailer is building trust, becoming a brand
that matters.

● It's where the money is
Non finance uses
➔ Specialist blockchains dedicated to one task
➔ Generalist blockchains to be used as a 'platform'
