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.
A Primer on Blockchain and its Potential, with a Focus on the GCCZeyad T. Al Mudhaf
During my summer internship at BECO Capital, a technology-focused Venture Capital firm based in Dubai, I put together this primer on blockchain that demystifies this hyped up technology, covers key investment trends in the space both globally and regionally within the GCC*, and highlights both the barriers and enablers for wider blockchain adoption in the region. *The GCC is the Gulf Cooperation Council - comprised of the United Arab Emirates, Saudi Arabia, Kuwait, Bahrain, Qatar, and Oman.

practice
I T I S D I F F I C U LT these days to avoid hearing about
blockchain. Blockchain is going to be the foundation
of a new business world based on smart contracts.
It is going to allow everyone to trace the provenance of
their food, the parts in the items they buy, or the ideas
they hear. It will change the way we work, the way the
economy runs, and the way we live in general.
Despite the significant potential of blockchain, it is
also difficult to find a consistent description of what
it really is. A recent Google search for “blockchain
technical papers” returned nothing but white
papers for the first three screens; not a single paper
is peer-reviewed. One of the best discussions of the
technology itself is from the National Institute of
Standards and Technology, but at 50-plus pages, it is a
bit much for a quick read.9
The purpose of this article is to look
at the basics of blockchain: the indi-
vidual components, how those com-
ponents fit together, and what changes
might be made to solve some of the
problems with blockchain technology.
This technology is far from monolithic;
some of the techniques can be used (at
surprising savings of resources and ef-
fort) if other parts are cut away.
Because there is no single set of
technical specifications, some systems
that claim to be blockchain instances
will differ from the system described
here. Much of this description is taken
from the original blockchain paper.6
While details may differ, the main
ideas stay the same.
Goals of Blockchain
The original objective of the block-
chain system was to support “an elec-
tronic payment system based on cryp-
tographic proof instead of trust …”6
While the scope of use has grown con-
siderably, the basic goals and require-
ments have remained consistent.
The first of these goals is to ensure
the anonymity of blockchain’s users.
This is accomplished by use of a pub-
lic/private key pair, in a fashion that is
reasonably well known and not rein-
vented by the blockchain technology.
Each participant is identified by the
public key, and authentication is ac-
complished through signing with the
private key. Since this is not specific
to blockchain, it is not considered
further here.
The second goal is to provide a pub-
lic record or ledger of a set of transac-
tions that cannot be altered once veri-
fied and agreed to. This was originally
designed to keep users of electronic
currency from double-spending and to
allow public audit of all transactions.
The ledger is a record of what transac-
tions have taken place, and the order
of those transactions. The use of this
ledger for verification of transactions
other than the exchange of electronic
cash has been the main extension of
the blockchain technology.
The final core goal is for the system

Blockchain-Based Internet of Things: Review, Current Trends, Applications, an...AlAtfat
Advances in technology always had an impact on our lives. Several emerging technologies, most notably the Internet of Things (IoT) and blockchain, present transformative opportunities. The blockchain is a decentralized, transparent ledger for storing transaction data. By effectively establishing trust between nodes, it has the remarkable potential to design unique architectures for most enterprise applications. When it first appeared as a platform for anonymous cryptocurrency trading, such as Bitcoin, on a public network platform, blockchain piqued the interest of researchers. The chain is completed when each block connects to the previous block. The Internet of Things (IoT) is a network of networked devices that can exchange data and be managed and controlled via unique identifiers. Automation, wireless sensor networks, embedded systems, and control systems are just a few of the well-known technologies that power the IoT. Converging advancements in real-time analytics, machine learning, commodity sensors, and embedded systems demonstrate the rapid expansion of the IoT paradigm. The Internet of Things refers to the global networking of millions of networked smart gadgets that gather and exchange data. Integrating the IoT and blockchain technology would be a significant step toward developing a reliable, secure, and comprehensive method of storing data collected by smart devices. Internet-enabled devices in the IoT can send data to private blockchain networks, creating immutable records of all transaction history. As a result, these networks produce unchangeable logs of all transactions. This research looks at how blockchain technology and the Internet of Things interact to understand better how devices can communicate with one another. The blockchain-enabled Internet of Things architecture proposed in this article is a useful framework for integrating blockchain technology and the Internet of Things using the most cutting-edge tools and methods currently available. This article discusses the principles of blockchain-based IoT, consensus methods, reviews, difficulties, prospects, applications, trends, and communication between IoT nodes in an integrated framework.

lockchain—the decentralized replicated ledger technology that underlies
Bitcoin and other cryptocurrencies—provides a potentially attractive alterna-
tive way to organize modern finance. Currently, the financial system depends
on a number of centralized trusted intermediaries: central counter parties (CCPs)
guarantee trades in exchanges; central securities depositories (CSDs) provide secu-
rities settlement; the Society for Worldwide Interbank Financial Telecommunication
(SWIFT) intermediates global transfer of money; CLS Bank handles the settlement
of foreign exchange transactions, a handful of banks dominate correspondent
banking, and an even smaller number provide custodial services to large invest-
ment institutions. Until a decade ago, it was commonly assumed that the finan-
cial strength and sound management of these central hubs ensured that they were
extremely unlikely to fail. More importantly, it was assumed that they were too big to
fail (TBTF), so that the government would step in and bail them out if they did fail.
The Global Financial Crisis of 2007–2008 shattered these assumptions as many large
banks in the most advanced economies of the world either failed or were very reluc-
tantly bailed out. The Eurozone Crisis of 2010–2012 stoked the fear that even rich
country sovereigns could potentially default on their obligations. Finally, repeated
instances of hacking of the computers of large financial institutions is another factor
that has destroyed trust. When trust in the central hubs of finance is being increas-
ingly questioned, decentralized systems like the blockchain that reduce the need for
such trust become attractive.
It is no coincidence that Bitcoin was launched shortly after the failure of Lehman
that marked the peak of the global financial crisis. Over the subsequent decade,

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Bitcoin is the first practical solution to a longstanding problem in
computer science called the Byzantine Generals Problem.
Mark Andreessen
https://dealbook.nytimes.com/2014/01/21/why-bitcoin-matters/
13. Satoshi Nakamoto Research Paper(2008)
A purely peer-to-peer version of electronic cash would allow online
payments to be sent directly from one party to another without going through a
financial institution. Digital signatures provide part of the solution, but the main
benefits are lost if a trusted third party is still required to prevent double-spending.
We propose a solution to the double-spending problem using a peer-to-peer network.
The network timestamps transactions by hashing them into an ongoing chain of
hash-based proof-of-work, forming a record that cannot be changed without redoing
the proof-of-work. The longest chain not only serves as proof of the sequence of
events witnessed, but proof that it came from the largest pool of CPU power. As
long as a majority of CPU power is controlled by nodes that are not cooperating to
attack the network, they'll generate the longest chain and outpace attackers. The
network itself requires minimal structure. Messages are broadcast on a best effort
basis, and nodes can leave and rejoin the network at will, accepting the longest
proof-of-work chain as proof of what happened while they were gone.

• A miner is a agent who tries to mine blocks.
• When a miner mines a block, the block
is broadcasted to the network. If the block
is part of the longest chain, the miner can
get reward with bitcoin.

• A block is including transactions in a certain period of time.
• A block is including the former block’s hash value.
Therefore, it looks like a chain structure.
• The hash is recomputed for each value until a hash containing the
required number of zero bits is found. (set by “the difficulty”)

28. Consensus Algorithm : PoW in Bitcoin
28
A proof of work is a piece of data which is difficult (costly, time-consuming) to produce but easy for others to verify and which satisfies certain
requirements. Producing a proof of work can be a random process with low probability so that a lot of trial and error is required on average before a valid
proof of work is generated. Bitcoin uses the Hashcash proof of work system.
One application of this idea is using Hashcash as a method to preventing email spam, requiring a proof of work on the email's contents (including the To
address), on every email. Legitimate emails will be able to do the work to generate the proof easily (not much work is required for a single email), but mass
spam emailers will have difficulty generating the required proofs (which would require huge computational resources).
Hashcash proofs of work are used in Bitcoin for block generation. In order for a block to be accepted by network participants, miners must complete a proof
of work which covers all of the data in the block. The difficulty of this work is adjusted so as to limit the rate at which new blocks can be generated by the
network to one every 10 minutes. Due to the very low probability of successful generation, this makes it unpredictable which worker computer in the network
will be able to generate the next block.
For a block to be valid it must hash to a value less than the current target; this means that each block indicates that work has been done generating it. Each
block contains the hash of the preceding block, thus each block has a chain of blocks that together contain a large amount of work. Changing a block (which
can only be done by making a new block containing the same predecessor) requires regenerating all successors and redoing the work they contain. This
protects the block chain from tampering.
The most widely used proof-of-work scheme is based on SHA-256 and was introduced as a part of Bitcoin. Some other hashing algorithms that are used for
proof-of-work include Scrypt, Blake-256, CryptoNight, HEFTY1, Quark, SHA-3, scrypt-jane, scrypt-n, and combinations thereof.

51% Attack
Finality Problem
Performance limit
Heavy Capacity
If a miner or a pool got more than 50%
of the network’s mining hashrate, they would
be able to prevent new transactions and reverse
the transactions.
Public blockchains are an acceptable settlement mechanism
and layer for financial instruments. But public blockchains
by design cannot definitively guarantee settlement finality,
and as a result, they are currently not a reliable option for the
clearing and settling of financial instruments.

Bitcoin : 7tps
VISA : 4000〜6000tps
Participants must have the whole transactions.
The capacity is more than 70〜80GB

@Berkeley Blockchain
Usually, a Miner joins a pool which is a team of other miners and cooperates to mine.
Miner’s share
• Currently, there are no pools which get
more than 50%.
• Miners are mainly from China and the other
countries which the electronic bills are so low.

● The majority decision is represented by the longest chain, which has the greatest proof-of-work effort
invested in it.
● Nodes always consider the longest chain to be the correct one and will keep working on
extending it.
