Prof. Ahmed Banafa discusses the evolution of blockchain technology in 2019 and its applications in IoT, AI, and cybersecurity. He highlights the transition from 'explain this to me' to 'prove it to me' in the blockchain market, along with different consensus algorithms like proof of work and proof of stake. The document also explores various industry applications such as supply chain transparency in pharmaceuticals and food, showcasing the potential of blockchain to revolutionize processes and address challenges.

- 12. But what is Blockchain?

- 20. 2019 ? Paul Brody, Ernst & Young's (EY) Global Innovation Leader for Blockchain Technology, said the Blockchain market over the past 18 months has been moving through an "explain this to me" phase (PowerPoint) into the "prove it to me" phase (working conference room pilots).

- 42. Proof of Work vs. Proof of Stake
- 43. What is Proof of Work? Most cryptocurrencies including Bitcoin run on “proof-of-work.” Proof-of-work as a process has the following steps to it: • The miners solve cryptographic puzzles to “mine” a block to add to the Blockchain. • This process requires an immense amount of energy and computational usage.
- 45. Proof of Stake • Proof of stake is a different way to validate transactions based and achieve the distributed consensus. • It is still an algorithm, and the purpose is the same of the proof of work, but the process to reach the goal is quite different.
- 46. • Unlike the proof-of-Work, where the algorithm rewards miners who solve mathematical problems with the goal of validating transactions and creating new blocks, • With the proof of stake, the creator of a new block is chosen in a deterministic way, depending on its wealth, also defined as stake.
- 47. • No block reward • Also, all the digital currencies are previously created in the beginning, and their number never changes. • This means that in the PoS system there is no block reward, so, the miners take the transaction fees. • This is why, in fact, in this PoS system miners are called forgers, instead.

- 56. Blockchain Tracks To understand the direction of Blockchain technology in 2019 and beyond, we need to recognize the three tracks of blockchain technology:
- 58. -Pure R&D-Track: This track is focused on understanding what it means to develop a blockchain-based system. Ideally, Ideally, working on real use cases; but the ultimate goal is investigation and learning, not necessarily delivery of a working system.
- 59. -Immediate Business Benefit- Track: This track covers two bases: One: learning how to work with this promising technology. Two: delivering an actual system that can be deployed in a real business context. Many of these projects are projects are intra-company.
- 60. -Long-Term Transformational Potential- Track: This is the track of the visionaries, who recognize that to realize the true true value of blockchain-based networks means reinventing reinventing entire processes and industries as well as how how public-sector organizations function.

- 66. How Blockchain Can Help Advertising • For buy-side transparency: Blockchain for auditing • For sell-side transparency: Proof-of-view to fight fraud • PoV only records views from signed-in users, since the viewer’s unique ID is part of the information required for a view to be considered valid. • Since most people are only able to watch one video at a time, the PoV will invalidate views from a user who is streaming multiple videos simultaneously. • The PoV technology confirms that a video is actually being streamed by capturing information about the current frame at random times. • Using smart contracts to document views and who gets paid
- 67. Verifying the Authenticity of Returned Drugs • In the Pharma industry, drugs are frequently returned to the pharmaceutical manufacturers. • While the proportion of the returned drugs is small compared to the sales (about 2–3% of sales), the per year volume is in the range of $7- 10 billion. https://hackernoon.com/top-5-use-cases-of-blockchain-in-pharma-and-healthcare-that-you-should-know-about-77ccdd76369b
- 68. • In the US, the Drug Supply Chain Security Act (DSCSA) stipulates that all US manufacturers must implement serialization or barcoding of drugs at a package level by November 2018. • Also, by the end of 2019 these serial numbers must be used to verify the authenticity of the returned drugs. https://hackernoon.com/top-5-use-cases-of-blockchain-in-pharma-and-healthcare-that-you-should-know-about-77ccdd76369b
- 69. Industry Proof-of-Concept Currently, Merck in partnership with SAP has developed the SAP Pharma Blockchain POC app for this Use Case. SAP launched this first Proof of Concept in Q3 2017, and a second one in early 2018. The PoC for the Use Case works as follows, • SAP’s existing solution called ATTP (Advanced Track and Trace for Pharmaceuticals), generates unique identifiers for a drug package. https://hackernoon.com/top-5-use-cases-of-blockchain-in-pharma-and-healthcare-that-you-should-know-about-77ccdd76369b
- 70. • When a manufacturer ships a package they register the item on the SAP Pharma POC Blockchain, with the four pieces of information generated by the ATTP; the item number (based on GS1 standard), a serial number, a batch number, and an expiration date. https://hackernoon.com/top-5-use-cases-of-blockchain-in-pharma-and-healthcare-that-you-should-know-about-77ccdd76369b
- 71. • The distributor can extract the four pieces information from the packaging’s barcode, using a simple scanner mobile app, allowing them to verify returns . • Counterfeiter copies of barcodes can be avoided, since SAP has the added ability to track every time a package changes hands. • A map view within the mobile app also helps ensure that the drugs are in the expected geographical region.
