The Blockchain - The Technology behind Bitcoin Jérôme Kehrli
The blockchain and blockchain related topics are becoming increasingly discussed and studied nowadays. There is not one single day where I don't hear about it, that being on linkedin or elsewhere.
I interested myself deeply in the blockchain topic recently and this is the first article of a coming whole serie around the blockchain.
This presentation is an introduction to the blockchain, presents what it is in the light of its initial deployment in the Bitcoin project as well as all technical details and architecture concerns behind it.
We won't focus here on business applications aside from what is required to present the blockchain purpose, more concrete business applications and evolutions will be the topic of another presentation I'll post in a few weeks
Edge computing is poised to lead a technological transformation by processing data and applications at the edge of networks rather than sending all data to the cloud. It allows data to be processed locally at its source or nearby devices for faster insights. Edge computing is functionally used across sectors like energy, healthcare, retail, finance, education, and manufacturing where low-latency insights are important. However, edge computing also presents some strategic problems around delay times, bandwidth limitations, security risks, and communication challenges that need to be addressed.
The business world has been abuzz about blockchain technology across many industries, ranging from finance to healthcare. Blockchain appears to have significant potential to add a new element to the revered double-entry accounting method on which the accounting industry is based. Bitcoin/cryptocurrency is one of the application of broader blockchain technology or ‘the blockchain’.
Blockchain is an online register or a ledger of digitally recorded transactions which is encrypted in the form of blocks where each block is connected by a network of computers which store these blocks, together forming the Blockchain. Bitcoin was the first blockchain technology created in 2009, as a kind of virtual currency database, where all the transactions could be stored without any banks or governments involved. And at present, several corporates, startups, government and other agencies are looking for similar databases-often independent of virtual/crypto currency to solve some of the most intractable issues facing society. Many sectors such as finance, mobile app, healthcare, real estate, fintech, regulatory, insurance and others have a huge market potential for blockchain technology.

W hen people interact with each other, for example via financial transactions, sharing legal docu-ments or trading through supply chains, they need a high level of confidence that the data
recording their interaction is accurate and true.
A distributed ledger makes it possible to build applications
where multiple parties can execute transactions online without
the need to trust a central authority or indeed each other.
Over the past few years, the number of use cases for distributed
ledgers, and their more specialised form, blockchains, has been
increasing, as has the technology to support the underlying infra-
structure and build applications on top of it.
With a distributed ledger, every user has their own full, or in some
cases partial, copy of the database, referred to as a node, which
can be a physical device, a virtual machine or a software container.
Each node runs the relevant software to provide the infrastruc-
ture management and the relevant application, including the
ability to complete “smart contracts” that negotiate the direct
exchange of assets between participating nodes.
consensus
For a transaction to proceed, all nodes must verify a transaction
and agree its order on the ledger.
Doing so is termed “consensus”, which is necessary, for exam-
ple, to avoid double counting or overspending when it comes to
financial assets.
Consensus involves four steps, from the transaction being

Blockchains are distinguished from other distributed ledgers in
being updated by adding blocks of new transactions to create an
immutable tamper-proof log of sensitive activity.
The right to write blocks may require proof-of-work – which
can be time and resource intensive – the aim being to prevent, for
example, mass updates by bots.

Blockchain and its impact on Data Science and Financial ServicesRatnakar Pandey
The document summarizes Ratnakar Pandey's presentation on how blockchain is reshaping the financial and data science fields. The presentation covered distributed ledger and blockchain fundamentals, applications of blockchain in the financial industry like lending and smart contracts, and the intersection of blockchain and data science. Blockchain provides benefits for data scientists like access to large diverse data sources, improved data quality, higher processing power, and real-time analytics. Skills needed to work in this area include experience with blockchain platforms, distributed databases, coding, and staying up to date on new developments.
Presentation from Grace Hopper Celebration 2016. Topic: Blockchain and Internet of Things (IoT) in the IBM Bluemix platform includes Demo. Speakers: Valerie Lampkin, Sumabala Nair and Carole Corley
Blockchain is a distributed ledger that can be used to securely track digital assets and transactions without a central authority. It works by distributing a record of transactions across multiple nodes in a network that must reach a consensus on changes. Smart contracts allow digital assets and transactions to be automatically verified and enforced based on predefined terms. Some potential applications of blockchain technology include digital currencies, supply chain management, digital identity, and more.
The document discusses the potential benefits of blockchain technology for digital transactions. It explains that blockchain relies on consensus, smart contracts, and cryptography to create a decentralized ledger system that does not require trusted third parties. This could make transactions more efficient, less costly, and more secure compared to traditional centralized ledger systems. The document also provides several examples of how blockchain is being applied to areas like financial services, trade finance, real estate transactions, and the Internet of Things through companies in Singapore. However, it notes there are still uncertainties around security, implementation costs, and privacy that could limit blockchain adoption.
Presentation for Asian Financial Markets and Institutions, October 2016, HKU MBA Program. Covers basics of blockchain and distributed ledgers and discusses some current and potential applications.
Blockchain startup Marketpay provides escrow payment services to enable secure transactions on marketplaces and sharing economy platforms. It uses Ethereum smart contracts to automate escrow releases upon delivery confirmation. While blockchain technology is still emerging, use cases like Marketpay's escrow payments demonstrate how it can facilitate transactions with transparency and without the need for centralized intermediaries.
This document discusses cryptocurrency trading markets. It begins with an abstract that introduces cryptocurrency as a digital currency created using cryptography and blockchain technology. It then provides background on the development of cryptocurrency and discusses how cryptocurrency trading involves investing money in cryptocurrencies as long-term or short-term investments. The document goes on to explain key concepts related to cryptocurrency trading markets such as cryptography, blockchain technology, and different cryptocurrencies. It also discusses applications that can help with cryptocurrency investment and market study.
The document provides an overview of blockchain use cases. It begins with remembering the key components of blockchain like blocks, miners, proof of work, and distributed ledgers. It then discusses public versus private blockchains and how private blockchains allow for control over participants. Several specific use cases are outlined, including smart contracts, proof of existence services, digital notarization of photos/videos, digital weddings, lottery systems, alarm clock apps, and banking operating systems. It is suggested that 2017 will be a year when more blockchain proofs of concept and pilots move into limited production and early adoption.

over many computers of people that do not
know each other.
Instead of having a central authority, the entire
network of combined computers is responsible
for the integrity of the data, and via consensus,
approves changes made to that data

State-of-the-art in blockchain technology
1. Bitcoin: 2008 best known public $BTC cryptocurrency
2. Ethereum: 2013 Ethereum public, open-source block chain featuring smart
contracts. Gas fee for contract operation $ETH
3. Ripple: 2012 gross settlement system with company acting as validator $XRP
4. Hyperledger: 2015 permissioned open source blockchain from the Linux
Foundation community to support high-performance, standardized business
transactions
5. NEO: 2014 “Ethereum of China” digital identity; smart contracts $NEO
6. IOTA: 2015 uses Tangle acyclic graphs; resolves scalability challenges of
existing blockchain technologies without transaction fees; geared to
emerging Machine-to-Machine economy and Internet of Things $MIOTA
7. Hashgraph: 2016 fast; eliminates massive computation and energy needs
8. Elastos 2002: a completely de-centralised operating system with integrated
blockchains and a safe “smart web” using carrier box, merged mining $ELA

Blockchain protocols (part of governance)
POW (Proof of Work) consensus:
• Works in untrusted networks but relies on
high energy use and is slow to confirm
transactions
• Non-democratic since large mining farms
dominate this
• Example: Bitcoin
POET (Proof of Elapsed Time)
consensus:
• Efficient but requires processor extensions
• Put on chips to lock up power
• Hardware-based (Intel)
• Example: Hyperledger Sawtooth
POS (Proof of Stake) consensus:
• Works in untrusted networks but requires
intrinsic cryptocurrency
• Uses much less resources
• Example: Nxt
Solo/No-ops consensus:
• Validators apply received transactions
without consensus which is very quick but
can lead to divergent chains
• Example: Hyperledger Fabric V1
PBFT-based (Practical Byzantine
Fault Tolerance)
• Efficient and tolerant against malicious
peers but Validators need to be known and
totally connected
• Example: Hyperledger Fabric V0.6
Kafka/Zookeeper:
• Ordering service distributes blocks to peers
• Efficient, fault tolerant but does not guard
against malicious activity
• Example: Hyperledger Fabric V1

Airport Use cases
Cryptocurrency purchasing: Brisbane Airport is first aviation hub to multiple cryptocurrencies
Ticketing: The blockchain can tokenize the e-ticket. Through use of smart contracts, airlines can add
business logic and terms and conditions around how the ticket is sold and used. This opens the door
for tickets to be sold by different partners, and in real time, from anywhere in the world
Loyalty. Travellers often have to wait until points settle and accrue to use them, and they are limited
on where they can spend them. By tokenizing loyalty points on the blockchain, travellers can get
instant value by redeeming them on the spot. They can also use them more broadly as a marketplace
or exchange model. With points accepted as “currency” among more providers, travellers get an
easier and faster-to-use program that is more relevant to their personal preferences
Security and identity. Protecting data privacy is a clear issue when it comes to passenger records,
flight manifests and crew information which can be protected via the blockchain
Maintenance. Blockchain technology can transform maintenance logs, which at best are in
cumbersome databases and, at worst, are in paper binders. The blockchain can help the industry
ensure that parts procured are legitimate and can offer a “virtual copy” immutable record of the
provenance of every part on the plane, every time it has been handled and by whom, from the
beginning of the aircraft’s existence. This visibility is profound, and can take the practice of
maintenance, safety and aircraft security to new levels
Flightchain: British Airways, Heathrow Airport, Geneva Airport, Miami International Airport and SITA
Lab recently participated in a collaborative project to explore if and how blockchain technology can
help to create a “single source of truth” for flight data

What is an
ICO?
As per the definition given by ASIC
(Australian Securities &
Investments Commission) 2018
version 1
● An initial coin offering (ICO) is a
new form of funding, used by a
business or individual to raise
funds from various types of
investors through the internet
● ICOs generally operate by
allowing investors to use
cryptocurrency to purchase
coins via the internet for a set
period of time
