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.

Block chain and Bitcoin. A blockchain is a data structure that makes it possible to create a digital ledger of transactions and share it among a distributed network of computers.
Understand Crypto currencies, where to buy them, how to secure owned currencies and investment options. Presentation will give ideas to start investigating and exploration.
Virtual or digital currencies, with Bitcoin chief amongst them, have been gaining momentum and investment over the last couple of years. Offering an almost costless means of making payments around the globe, virtual currencies have the potential to bring significant disruption to the banking industry. This potential is not lost on either Bitcoin startups or banks themselves. But how does Bitcoin actually work? A peer-to-peer network maintains the “blockchain”, an innovative cryptographic protocol which securely mediates payments between parties without mutual trust. This session will step through the structure of the blockchain, showing how it solves the “double spend” problem and allows decentralised processing of financial transactions. Whether Bitcoin will become the currency of the internet or it’s a bubble that is doomed to burst sooner or later, the blockchain itself will change the face of transactional banking and perhaps other industries along the way.

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.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.
2. For today
• Block chains are incredibly popular now a days.
• How do they work?
• How can they be used?
• What are the threats to technology?
3. A LITTLE History
• This technique was originally described by a group of
researchers in 1991 and was originally intended to
timestamp digital documents so that it is not possible to
backdate them or to tamper with them.
• 2009 Satoshi Nakamoto (pseudonym) in his paper “
Bitcoin: A Peer-To-Peer Electronic Cash System ”.
• This paper introduced a peer-to-peer version of
electronic cash which allows to conduct online
payments without need of a bank as intermediate.
4. WHAT IS IT ACTUALLY ?
• A blockchain is a distributed ledger which is open to
anyone.
• once a data has been recorded inside a blockchain it
becomes very difficult to change it.
• Each participant (device) in the blockchain network are
termed as ‘node’.
• Blockchain ensures transparency and integrity of
transaction through mathematics and not through trust.
• Persistent, transparent, public and append-only ledger

Miners
• Incentive
10. Proof-of-work
• Modern computers can mine a block seconds. Modern
computers are powerful
• If someone tamper with blockchain and recalculates all
hashes then system will be valid even though a block is
modified
• To solve this
• Miner has to put a lot of computing power.
• Bitcoin requires hash of block to begin with zeros.
• Output of hashing function cannot be influenced. A lot
of combinations have to be tried. Requires lot of
computing power
11. Proof-of-work
• This amount of zeros require is termed as ‘difficulty’. If
machines gets more powerful difficulty will be increased
by the Bitcoin team.
• Difficulty : 6,379,265,451,411
13. PUBLIC key cryptography
• Asymmetric encryption.
• Two parties involving in communication will have a pair of
keys public key and a private key. [RSA algorithm]
• These keys are mathematically linked but you cannot re-
engineer private key from public key and vice versa.
• When exchanging data both parties shares their public keys.
• Suppose Alice is sending a data to Bob. Alice encrypt the
data with Bob’s public key. Then sends the data. Bob on
receiving the data can decrypt the data using his private
key. Only bob is able to do this not even Alice. They require
to keep private key safe
• In Cryptocurrencies this makes sure that only the owner can
retrieve the money.
14. PUBLIC key cryptography
• All blockchain transaction involves two parties. Sender
(request initiator and receiver). Both have a public key
• This public key or unique identification is received by
each other.
16. P2p network
• Distributed ledger

17. Blockchain program
• Blockchain program, not only in finance sector.
• Currently implemented across multiple domains.
• Blockchain can be implemented by using any language,
• Solidity is the preferred
• 24 hours is required to implement a new blockchain.
18. Blockchain transactions
• Each transaction is verified by a miner by solving a
complex puzzle. Once he solves the puzzle and verify
the block he maintains and updates the ledger.
• The mathematical principle ensures that the nodes
automatically and continuously agree the current state
of the ledger and every transaction in it. Ensures that
everyone in network has same set of transaction and
same set of ledger.
• If anyone tries to corrupt a transaction, the nodes will
not arrive at consensus and hence will refuse to
incorporate the transaction in blockchain.
19. TYPES
• Public: similar to Bitcoin, go ethereum. Anyone in the
word can be a part of it. You can read and write data to
this blockchain if you are a miner of part of peer-to-
peer network as well.
• Private: only allow specific central persons of an
organization has the right to verify and add blocks to
blockchain. Anyone on internet can view the blockchain.
• Consortium: it is something public as well as private,
here a group of people can verify and add transaction
to blockchain. The creator has to specify the view of
blockchain to public if required by him.
20. Blockchain use cases
• Payment and transaction
• Health care
• Law enforcement agencies
• Voting system
22. Cryptocurrencies
• Concept of money
• The ledger concept
• Issues in this conventional system
• Require a transaction fee for each transactions
• Bank’s ledger is private and customer can’t even know where
his own money is getting invested or utilized by the bank
• A hacking attempt on ledger of bank can cause complete loss
of our money.
• Double spending issue
• Bitcoin is a blockchain not build on blockchain tech.
23. Cryptocurrencies
Benefits
• You control your money not banks.
• You can store your money on a smartphone or a pen
drive.
• Send money to anyone anywhere in world anytime.
• No transaction fee or intermediate commissions
required.
• Your identity completely anonymous thus no one can
track you even the receiver.
24. Smart contracts
• First used by Nick Szabo in 1997. He wanted to use a
distributed ledger to store contracts.
• Similar to real world, difference is that they are digital
• Smart contracts are tiny computer programs that are
stored inside a blockchain.
• Kickstarter
• Removes the middle man.
• Loans to offer automatic payments, insurance
companies can use them to process certain claims,
postal companies can use them to payment on delivery.
25. Smart contracts
• Ethereum
• Special programming language: solidity (JavaScript like
syntax)
• Bitcoin has support for smart contracts it is limited.
• A smart contract is a computer program that runs on a
blockchain network. It can be used to automate the
movement of cryptocurrency according to prescribed
rules and conditions.
26. RISK IN IMPLEMENTATION
• No system build perfect
• Blockchain is not yet hacked
• Faulty implementation
27. HACKING
The 51% rule
• Inherent to most cryptocurrencies
• Proof of work protocol for verifying transactions.
• Nodes spend vast amounts of computing power to
prove themselves trustworthy enough to add
information about new transactions to the database.
• Creating an alternative version of the blockchain: fork
• Attacker having dominance in computing power can
make fork the authorized version
• Double spending.
28. HACKING
Smart-contract bugs
• Fund, called the Decentralized Autonomous
Organization (DAO), 2016, Ethereum.
• Flaw allowed the hacker to keep requesting money from
accounts without the system registering that the money
had already been withdrawn, stole $60 million
• Patch – Additional Smart Contracts, Centralized Kill
switches.
• Re forked new chain, old one is now Ethereum Classic
29. QUANTUM COMPUTING
• It makes use of quantum bits or qubits instead of binary
digits like we use in the current computing system.
• Quantum bits (qubits) which had multiple values at the
same time
• 100 million times faster than current systems
• Cryptocurrencies work on public key cryptography.
• Only on forward creation of key must be made possible
(easy)
• Always a way to go backward. By going through every
single possibility.
• This link is equal to the factors of a number which is a
product of two enormous prime number. For the hackers to
extract the private key, the hacker would have to work out
the factors of that number which is the product of the prime
numbers
31. CONCLUSION
• Blockchain basically uses various mathematical
functions and as well as algorithms to create a highly
secure and distributed ledger system. Which enables
transactions to take place with our need of a third-party
or any need of transactions fee or commission. This is
why blockchain is called as a trust less system. You
don’t have to trust a third-party to make out your
transactions.
