The banking industry needs to know about blockchains, as it stands to possibly force a paradigm change upon the entire industry. This talk focuses on introducing blockchains to laymen bankers in the 8th Annual Bank Tech Asia (Manilla Series).
Blockchain isn't a household buzzword, like the cloud, the web, the internet of things or bitcoin. It's not an innovation that you’re able to see and touch as easily as a smartphone or a NEST thermostat. But in a world where anyone (and anything) can establish a digital persona or publish content online the blockchain may be the answer to a question we've been asking since the invention of the internet: how do we establish trust amongst stakeholders on digital platforms?
This keynote presentation provide a quick, nontechnical introduction to the blockchain. We’ll then take a quick tour through the blockchain technology landscape, understand what a computational blockchain is and discuss the notion of smart contracts and digital tokens.
We’ll wrap up with a focus on blockchain uses cases and initiatives in education.

Blockchain: The Information Technology of the FutureMelanie Swan
The blockchain concept may be one of the most transformative ideas to impact the world since the Internet. Cryptocurrencies like bitcoin are merely one application of the blockchain concept. The blockchain is a public transaction ledger built in a decentralized network structure based on cryptographic principles so that any kind of trading, buying and selling of assets does not need to go through a centralized intermediary. Any kind of asset may be encoded into the blockchain and transacted, validated, or preserved in a much more efficient manner than at present including ideas, health data, financial assets, automobiles, and government documents. Venture Capitalists are calling the blockchain the next big investment wave.
This Edureka Blockchain technology tutorial will give you an understanding of how blockchain works and what are blockchain technologies. This tutorial helps you to learn following topics:
1. What are Blockchain & Bitcoin
2. Blockchain Technologies
3. Peer to Peer Network
4. Cryptography
5. Proof of Work & Blockchain Program
6. Ethereum & Smart Contracts
7. Blockchain Applications and Use Cases
The fundamental security properties of blockchain originate from both bitcoin architecture and cryptography advances. the proficiency of the cryptographic chain of blocks was advanced giving birth to various inborn security qualities.
This is an introduction to the exciting technology powering innovation in finance, contracting and many technology industries. This slideshow touches on the blockchain; what it is, its applications, it's disruptions and future cycle projections. The slideshow also touches on bitcoin as a popular application of blockchain technology.

The revolutionary invention of blockchain is still a controversial topic, and Intellectsoft software development company is about to bring clarity in it. Being the leader in blockchain developing and consulting, it explains in simpler words the elegance of using this brand-new technology as a business decision. Specifically, the company facilitates the understanding of blockchain by both offering the readers essential facts about the innovation and creating applicable recommendations for further practical implementation.
To start with, Intellectsoft provides an overview of blockchain essentials, investigating the nature of this technology along with its structural elements. As a result, a key concepts of blockchain, including digital fingerprinting and access keys, are no longer a mystery for readers. Furthermore, the opportunities of Smart Contracts and mining are explained. In these sections, Intellectsoft already illustrates previously presented theoretical assumptions with practical examples. And the overview achieves a higher clarity, which facilitates the task of developing a blockchain decision for anyone interested. Then, the presentation proceeds to the question of blockchain real-time applications. This includes providing the list of industries that can benefit the most from the innovation and the real advantages their representatives can gain. The special attention is paid to financial services, government, and healthcare, among others. Finally, after describing the major differences between private and public blockchain, Intellectsoft creates recommendations for those interested in the implementation of this decision into business. And after reading, you will get much closer to the decision whether blockchain really deserves its place in your business practice specifically.
Blockchain. Everyone talks about it, but how does it really work?
This talk covers the fundamentals and discusses real world examples of how blockchain is being used to transform healthcare, real estate, humanitarian aid, governance and other domains.

The world is growing more decentralized, in large part due to the transformative power of the internet.
- While originally thought to be isolated to use cases such as email and news media, the internet laid the foundation for unprecedented, multi-billion dollar industries and innovations such as ecommerce, social media, the cloud, smartphones, and online gaming
- However, the internet also enabled activities like identity theft, unwarranted surveillance, and the monopolization of personal data
- Blockchains bring security and privacy to the decentralized, digital world potentially addressing many of these undesirable consequences of the internet
Blockchain technology carries a similar revolutionary potential to that of the internet, though be wary of the hype.
- By making certain data immutable and shared across a network, blockchains allow value to be digitized, exchanged, and recorded without the facilitation (and cost) of a trusted third party – something truly unprecedented
- This means that any industries not already disrupted by the internet whose services include data collection, curation, verification, and/or dissemination could now be disrupted, especially those that are currently centralized and monopolized (e.g., banking)
- This also means that services previously susceptible to malpractice once digitized (e.g., voting and music sharing) can now be safely and securely brought into the 21st century
- And finally, this means that the tedious activities associated with data silos and imperfect communication, like filling out a medical history form every time we visit a new doctor, can be things of the past. We can now make (and own) one record that's stored on an immutable, append-only blockchain, and anyone we select can reference our record anywhere at any time
- Despite this awesome potential, we are still very much in the early 90s of the blockchain adoption and development curves. Much work has yet to be done as the technology matures, and business cases are only beginning to be flushed out. The priority now is to learn and pursue low-risk pilots
This report explores the definition of blockchains, how they work, the current state, and next steps for putting distributed ledger technologies on the radar.

My presentation prepared for the one-day national level workshop on "Blockchain Technologies" organised by the Department of Information Technology, Academy of Maritime Education and Training. The presentation covers the definition, classification, components, structure and working of ethereum and bitcoin blockchains.
A talk I gave, as part of a roundtable on CivicTech, on blockchain and smart contracts. Legal considerations are discussed as well as the technology considerations.
Hands-on introduction to blockchain technologies.
First, basic concepts as peer-to-peer networks, mining and distributed consens are introduced basd on the Bitcoin protocol. Next smart contracts are discussed for the Ethereum protocol and demonstrated using a local/private blockchain.
The session concludes with a live demo of the interaction of a Java based classical business application with a smart contract running in the Ethereum network.
The goal of the session is to provide a meaningful background of blockchain technologies in genral and to enable developers to start exploring Ethereum and smart contracts within a few hours.
The proposed development setup is oriented towards Java developers and contains Docker images for the Geth and TestRPC Ethereum clients that can be run locally. To access Ethereum from Java the web3j Java library is used. The business application that integrates with the smart contracts is built with the Eclipse Scout framework.

Blockchain Primer - Founder Collective - December 2017Parul Singh
As 2017 comes to a close, blockchain is everywhere (or more accurately perhaps “bitcoin, bitcoin, bitcoin.”) here is a primer on blockchain that I prepared for my team at Founder Collective to help frame some of the exciting use cases we see coming down the pike. Further reading is on the last slide.
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.
Blockchain technology is a structure that stores transactional records, also known as the block, of the public in several databases, known as the “chain,” in a network connected through peer-to-peer nodes. Typically, this storage is referred to as a 'digital ledger.

Kristof V. explained the basics of blockchain and smart contracts. Starting with the mechanics of bitcoin (introduced by the 2009 paper of Satoshi Nakamoto) he explains concepts of pseudonymisation, encryption, blockchain, mining, and distribution. After skimming high-level through some use cases he moves to "(smart) contracts", using the example of an auction.

An introduction to the basic working mechanism of bitcoin and blockchain: how bitcoin works, bitcoin network, nodes, miners, hashing, difficulty and nonce, etc, why bitcoin mining consumes so much energy. Variations of blockchain, MDL.
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?

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

A network of nodes each containing a copy of the database
Nodes uses a consensus protocol to agree on what is true in the
database
Data is append-only / immutable, meaning once written into the
database, it cannot be removed, or tampered with
Malicious activities are curtailed by its verification mechanism,
preventing attacks like double spending

Bitcoin is the first digital currency that works
Traded at USD 13 in 2013, now USD 445 in 2016
Released by “Satoshi Nakamoto” in January 2009
Market capitalisation currently at USD 7 billion
Bitcoin’s blockchain is the first public blockchain
Uses Proof-of-work + Longest chain consensus model
Source code is open source - understanding how bitcoin works does
not mean you can attack it in any way

BITCOIN BLOCKCHAIN OVERVIEW
13
A bitcoin blockchain is made from a chain of blocks
Each block has a hash as their ID
Each block contains the hash of the previous block
This creates a “chain”, or in computing terms, a linked list
Block 1
id: 001
prev hash:
000
Block 2
id: 002
prev hash:
001
Block 3
id: 003
prev hash:
002
Block 4
id: 004
prev hash:
003
14. SLIDE #
A block contains a list of Transactions
… and some misc. meta-data
First Transaction is a Block Reward
Originally 50 bitcoins
Now 25 bitcoins
Soon halving to 12.5 bitcoins
INSIDE A BLOCK
14
Block
Transaction 001
Transaction 002
Transaction 003
Transaction 004
Transaction 005
Transaction 006
…
15. SLIDE #
Each transaction contains inputs and outputs
1 or more Inputs
Which previous output’s coins to spend
Verification details (signature)
1 or more Outputs
Which address to pay coins to
Contract to fulfil in order to receive coins
INSIDE A TRANSACTION
15
Transaction
Input - 10 coins
Input - 2 coins
Output - 5 coins
Output - 3 coins
Output - 2 coins
Output - 1 coin
16. SLIDE #
Outputs describe x amount of coins paid to an address
“Address” is essentially a key; if you have the key, you can unlock the
output and redeem the coins
Outputs can contain complex scripts - paving the pay for smart
contracts
REDEEMING OUTPUTS

AND EACH “ADDRESS” REQUIRES A PRIVATE KEY TO ACCESS IT

20. SLIDE #
Each node races to solve a mathematical puzzle called proof-of-
work
First to solve the puzzle gets to add a new block to the chain
Once new block is added, miner collects block reward
Possible that 2 nodes will solve the puzzle at the same time, creating
a race condition and a fork in the chain
Forks are resolved through the longest chain protocol
Proof-of-work + longest chain = bitcoin consensus model
BITCOIN MINING
20
21. SLIDE #
Every transaction records:
How many bitcoins were created as block reward
How many bitcoins were transferred from address A to address
B - inputs to outputs
Great ledger because once a block is added, it cannot be removed or
changed
Attacking the network is extremely costly: electricity cost easily cost
more
BITCOIN AS A LEDGER
21
22. SLIDE #
Ledger is public and anybody can view it
Anybody can start a node and mine bitcoins
Anybody who owns a node has the entire ledger
Owning a node doesn’t mean you can tamper with it
Owning a node doesn’t mean you can attack the network
Owning a node doesn’t mean you can mine malicious blocks
BITCOIN AS A LEDGER
22
24. SLIDE #
BLOCKCHAINS AS DISTRIBUTED LEDGERS
24
Immutable, tamper-proof audit-trail
Data easily shared and verified, forced transaction through protocol
Vastly increased security, less vulnerable to attack or outage
Programmable contracts that can radically reduce human errors and costs
“While Fintech Disrupts Banks,
the Blockchains Disrupt Fintech"
25. SLIDE #
Smart contracts that are immutable removes the need for a trusted
intermediary to facilitate any form of lending
Both peers agree on a contract, and trust the blockchain to execute
the contract once both sides fulfil their side of obligations
Possible implementations:
Executing wills
Escrow for digital goods trade
SMART CONTRACTS
25
26. SLIDE #
Since data stored on the blockchain is immutable, ownership
information can be stored on the blockchain
Example implementations
Property ownership
Car ownership
Commodities ownership (gold, silver, etc)
Creative products ownership (art, music, etc)
OWNERSHIP DATA

27. SLIDE #
Combines smart contract with ownership data to:
Play music on specific devices, embed contract into music file
Play games on specific machines, embed contract into game files
Operate software on specific machines, can expand to enterprises
and tie into their user database and authentication systems

Government services tied into smart contracts based on
biometric data

There are other technologies, like blockchains, which is used
for bitcoin, but can also be used for many other applications
like real-time gross settlement, or trade finance verification. So
our banks and our regulators must keep up to date and up to
scratch with these developments

Bitcoin has a bad reputation, and tainted the perception of its
underlying technology (aka blockchains)
Bitcoin, the biggest blockchain, limits itself to 7 tps (vs. VISA at 2,000
tps, max at 56,000 tps)
Non-bitcoin blockchains face technical challenges related to
consensus model
Outside of bitcoin, no standardisation on what blockchains should be
or what protocols blockchains should have at a minimum
Regulators are often overwhelmed by the speed at which blockchains
are developing, let alone understand what they are
BLOCKCHAIN CHALLENGES
36
37. SLIDE #
Industries may be forced to experience a paradigm shift once
automation is enabled by blockchains
Security models are unknown for now, most blockchains are not
battle tested
Most blockchains are at experimental and prototypal stage, not
suitable for mass deployment yet
Difficulty in justifying ROI to senior management, who holds the keys
to funding necessary for blockchain development
There is a divide between industry experts and blockchain engineers
