Blockchain provides a decentralized trusted framework by achieving distributed consensus without a centralized trust entity. It addresses issues like dependency on single entities, double spending in cryptocurrency, and verification of transactions and ownership changes through mechanisms like public key encryption, mining, and cryptographically linked blocks. Applications of blockchain extend beyond currency to various financial areas like banking and insurance as well as non-financial domains such as IoT, legal contracts, and digital asset ownership.

Blockchain, smart contracts and use cases for the Legal HackersKoen Vingerhoets
On the 20th of June, the Brussels Legal Hackers invited @KristofVerslype and myself to explain #bitcoin, #blockchain and #smartcontracts. We added some use cases to spice up things. This set only contains my slides for the evening.
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.

Blockchain for Land Records and Real EstateJohn Mirkovic
An in-depth presentation on why and how blockchain technology can be applied to keeping government records of real estate transactions. Information on how bitcoin and blockchains function.
Everything you've been told about blockchains is wrong: the "killer app" isn't any particular implementation, but the database design itself. In this presentation I explain how the permissioned blockchain design pioneered by Eris Industries actually addresses the problems and use-cases everyone's said blockchains can solve, but hasn't actually used them to solve.
Hint: it's not because of "decentralisation."
What is a blockchain? How do the existing contenders compare? Listing purpose and features of Bitcoin, Zerocash, Ripple, Stellar, Hyperledger, Ethereum, Tendermint and Eris on that basis.
Talk at the 3rd Blockchain Workshop, London 2015. By one of the pre-eminent blockchain researchers, Vlad Zamfir.
Slides used during the first Studio on Air event. Topics were AI & blockchain, I covered the latter. As the focus was twofold, to explain what blockchain is about and to give some learning nuggets,

Exploring Blockchain Technology, Risks, and Emerging TrendsAmazon Web Services
Blockchain has become a hot topic for enterprises, start-ups, entrepreneurs, and regulatory bodies. Born from bitcoin in 2008, blockchain's promise of a distributed ledger has far greater implications than cryptocurrency. Companies are now beginning to understand its disruptive potential and are experimenting with its most promising applications. But, few companies have asked the more fundamental question: Are we ready to adopt a shared public database for financial transactions? In this session, we cover the concepts of blockchain and use cases in the enterprise. We also demonstrate blockchain in use and show how to implement it using AWS services.
Speaker: Anand Iyer, Principal Solutions Architect, AWS
Blockchain and real-estate transactions appear to be a perfect match because there is an need of secure and immutable ownership records and trust is very important.
In some countries, like Georgia, the real-estate industry is already embracing blockchain technology.
Some others are experimenting with the technology, like China's Xiong’an New Area.

Omni chain presentation - DBS Blockchain HackathonTaulant Ramabaja
Slides from the 2015 DBS blockchain hackathon winners.
OmniChain makes it possible for practically any existing database to acquire "blockchain-like" capabilities without any of its downsides. Such integrated databases acquire: Immutability, encrypted distribution and backup of data, as well as independent data verifiability. All other original properties of the database are kept intact. We believe OmniChain will make an "internet of blockchains" possible and therefore drive down costs for existing financial institutions as well as open new markets in developing economies due to lower technological friction.
Real world applications include securitization of loans as well as leasing agreements in developing markets, tracking of financial exposure of existing secuitization chains in developed countries, as well as independently verifiable financial statement tracking.

When it comes to the Internet of Things, a blockchain can be provide a platform to handle device authentication process and thereby prevent a spoofing attack by malicious parties who may impersonate some other device to launch an attack to steal data or cause some other mayhem.Blockchain will allowdirect communication between two or more devices so that they are able to transact without going through a third-party intermediary, and in effect make spoofing more cost prohibitive. This White Paper explains how blockchain can improve the security of IOT devices.

Blockchain-based shared ownership of City Platform CooperativesDigitalTown, Inc
Discussion of how citizens can locally own Platform Cooperatives to power thriving, sovereign local communities. Presented at Smart City Expo - Barcelona, November 15, 2017 by Mike Cartwright, CTO DigitalTown.
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?

Blockchain Introduction - Canada Nov 2017.pptxAntony Welfare
Back in 2017 I joined the world of #Blockchain and presented my first ever Blockchain presentation on 14th November 2017 at a Tech meetup in Penticton, BC (Canada)
A few key highlights:
* The fundamentals of Blockchain technology have not changed (Trust, Transparency, Security, Quality/Certainty, Reduced costs)
* We were talking about Web 3.0 back in 2017 😉
* People still miss define Blockchain
* Janet Yellen and Christine Lagarde were commenting on Blockchain back in 2017
* Checkout the Dapps section – I was ahead of my time there!
* And the last three slides on the Market cap and increases – I was excited to tell people the market cap was $200bn, BTC was $8,000 and ETH was nearly $400 ……… Ahhh the good old days 😉
And finally – my “leaders comment” back in 2017 still stands “Blockchain is the next disruptive technology to transform the lives of our customers and our business operations”
What a journey so far…and guess what…its only just begun 👍👍👍
A Blockchain is essentially a distributed database of records or public ledger of all transactions or digital events that have been executed and shared among participating entities. Each transaction in the public ledger is verified by consensus of a majority of the participants in the system. And, once entered, information can never be erased. The Blockchain contains a certain and verifiable record pf every single transaction ever made. Bitcoin, the decentralized peer-to-peer digital currency, is the most popular example that uses block chain technology.
The Bitcoin itself is highly controversial but the underlying Block-chain technology has worked flawlessly and is all set to democratize our digital world. The main advantage of Block chain is that it establishes a system of creating a distributed consensus in the digital online world. It is finding applications in both financial (e.g. Nasdaq Private Equity, Insurance) and non-financial worlds (e.g. Decentralized IoT, Decentralized proof of existence of documents) by removing the dependency on a single Trusted entity. This disruptive technology opens the door for developing a democratic open and scalable digital economy from a centralized one.
1. Blockchain: Bitcoin and Beyond:
Move from Centralized to
Decentralized Trusted Framework
Sanjeev Verma
2. BREAKTHROUGH
25 years ago a breakthrough
technology that connected people
Connected people around the world,
foundation for modern growth.
Today the Internet gives a new
breakthrough-BLOCKCHAIN
Changes the way economy & businesses
work
Distributed Consensus without a
centralized Trust Entity.
4. Problem: Dependency on a Single
Trusted Entity
• Trust in Digital Economy is Broken:
– We depend on Email Server ( like GMAIL) for
secure delivery of our emails.
– Social network like Facebook to broadcast our life
events to our loved ones.
– CA for our Digital Certificates...
• We are living our life precariously by relying
on a Third Party for the security and privacy of
our digital assets.
5. Solution: Move Towards Decentralized
Trusted Framework
• Solution:
– Decentralized Trusted Framework instead of a Single
Trusted Entity.
• Bitcoin is the first Cryptocurrency that gave a Trusted
solution using Blockchain ( based on 2009 paper).
6. What is Money?
• Money is means for exchanging goods and
services & has 4 properties
– Divisible, Durable, Fungible and Verifiable.
• Bitcoin like other Fiat Currency like US $ is
based on trust.
• Bitcoin unlike US $ is deflationary since there
can be a maximum of 21 Millions Bitcoins in
Bitcoin network ( by year 2140).
7. Requirements of a Trusted
Cryptocurrency system
• Requirements of a Trusted Cryptocurrency
network:
– Verification of the entity initiating transaction.
– Trusted Ownership changes.
– Transaction ordering to prevent fraud ( double
spend).
10. #3 Transactions Ordering to prevent Double Spend
Double Spend problem
• Alice ( consumer) sends
cryptocurrency to Bob (
merchant to buy a product.
• Alice Waits for Bob to ship the
product.
• Alice conducts another
transaction referring the same
input to himself/herself.
• Due to propagation delay,
second transaction go
through. Bob ships the
product and does not get his
money too!
Bitcoin was the first cryptocurrency to address this problem using a
mechanism—now popularly known as Blockchain.
11. What is Blockchain?
• Blockchain is a decentralized public ledger
– Public Key is your A/C #
– Private Key your key to get access
– Entries verified by distributed computing entities
(called miners)
13. Miners work on unconfirmed transactions
and packages them into a Block.

e.g. Pick a number such that the hash of all the blocks
content has 5 leading zeros.

10^8 Gig hashes to solve a single Block.
How a Block is Generated?
15. Blockchain Blocks
Blocks are cryptographically linked together: A Block can’t be solved
until previous block is solved
16. Occasionally there could be more than one block solved at a time:
In Bitcoin Network it takes on average 10 minutes to solve a Block.
Bitcoin Network finally stabilizes to a single
chain that is trusted by everyone in the
network.
17. How Blockchain addresses the issue of double spending?
Mathematical Race starts

18. You need 50 % of the Computing Power to Break the System!
19. Blockchain Advantages
• Two Main Characteristics
– Distributed Consensus
• Past and Present events involving digital assets can be
verified by anyone by looking at Blockchain at any time.
– Anonymity
• Use of public cryptography ensures privacy of the
digital assets.
20. Applications of Blockchain
• Monetary Aspect is the tip of the iceberg-
Blockchain is ground breaking technology:
– Financial Applications
• Stock Exchange, Insurance,
– Non-Financial Applications
• Notary, Proof of Existence of Legal Documents, IoT,
Distributed Storage,
• Escrow Service
21.
22. What is Smart Contract?
• Computer Programs that enforce the terms of
a contact:
– Self Enforceable
– Transparent
– Faster
– Cheaper
25. Smart Property
• Smart Property is a physical property whose
owner is controlled by Blockchain using Smart
Contracts
– It also includes non-physical properties such as
shares in a company or access to a remote
computer.
– Examples include Cars, Houses, Diamonds etc.
26. Blockchain based AirBnB service
• Smart Property can be used to implement a Blockchain-based AirBnB service- From
Brokerage Service to Escrow service
27. Some Other Applications
• Decentralized Proof of Existence of Legal Documents:
– Cryptographic Hash or fingerprint of legal documents can
be stored in the Blockchain.
• Decentralized IoT
– Current implementation is based on a centralized hub or
broker.
– IBM’s ADEPT uses Blockchain as a general ledger to keep
secure messages exchanged between IoT devices.
– Filament a start-up provides a decentralized Software stack
that stores the digital identities of the IoT devices in a
Blockchain.
29. Conclusion
• Blockchain is a disruptive technology
– Distributed Consensus and Anonymity are its two
main characteristics.
– Finding newer applications in both Financial and Non-
Financial space.
– A new term Fintech has been coined to describe its
applications in financial space.
• Still has challenges in terms of scalability, govt
regulations and behavioral change in trade
without involving third party.
