3. Blockchain: A brief history
After the internet, multiple attempts of creating digital currencies that solved the “double spend” problem came and went with no success.
In 2008, “Satoshi Nakamoto” published a whitepaper in an online forum titled “Bitcoin- A Peer to Peer Electronic Cash System”. Based on technology
A year later the technology is built and the bitcoin network is distributed to the public.
Fast forward to the present, blockchain research and development has grown exponentially, with thousands of projects developing unique block chain solutions to problems across multiple industries

4. What is blockchain?
An immutable, distributed ledger that can store information about and/or facilitate transactions on a trustless, decentralized network with finality.
Immutable - Cannot be altered
Distributed - The ledger is available and free to view by anyone
Trustless – Parties can transact without a trust based system, such as a third party verifier.
Decentralized – No governing authority, allowing for censorship resistance, and greater security than single point of failure centralized authorities (banks, big data centers etc.)
Finality – ledger acts as a single shared source of information to verify ownership of an asset and/or completion of a transaction

6. How does it work? Use Case Car Ownership Example

8. Inherent Value
use ibm blockchain for dummies shortcomings of current systems

9. Part 2: Blockchain as a Platform

10. Ethereum Platform A Virtual Machine or “World Computer”.
A platform for decentralized applications
Enables Smart Contracts
Native Token “Ether” not a currency, but “gas” used to pay for transactions on the network. Incentivizes users to participate in the network.
Currently the most decentralized network/highest number of nodes,
largest developer network

12. About Smart Contracts

13. OmiseGo (FinTech)

14. Golem Users can rent or offer processing power over the network.
Useful for users that do not have e
expensive hardware
Expanding into machine learning
and AI

15. Brave

16. Moving Forward Technology is still young
Decentralized blockchains face scalability problems
Ease of use still needs improvement
Regulatory uncertainty
