Cryptocurrencies - A Serious IntroductionDrake Emko
A high level overview of the world of Cryptocurrencies, liberally illustrated with Doge memes.
This was a lightning talk (5-7 minutes), so it scratches the surface, hopefully enough to get you interested in the world of cryptocoins.
It begins with the basic definitions, the reasons to use and accept cryptocurrency, the main currencies (Bitcoin, Litecoin, Dogecoin), the many altcoins and their distinguishing factors, and finally introduces you to cryptocoin mining (producing your own coins using your computer).
Slides from a talk given to a Students for Liberty group at the University of Pittsburgh in February 2017. This talk covers what Bitcoin is, how it works, why people use it, how to use it, and how Bitcoin's innovation is impacting everything from payments to software to government.

An Introduction to Bitcoin-The Digital Form of currencyBirju Besra
This PPT give an introduction to cryptocurrency Bitcoin. It is a digital form of currency. It is a decentralized currency , that is no central govt. or authority controls it. It is a direct peer to peer money transaction.
Bitcoin is a digital, decentralized, partially anonymous currency, not backed by any government or other legal entity, and not redeemable for gold or other commodity. It relies on peer-to-peer networking and cryptography to maintain its integrity. 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.

This slide briefs you about the BItcoin/Cryptocurrency knowledge and facts. This slide is made for diffrent purpose but sharing here to help someone getting a quick knowledge of Bitcoins.
Cryptocurrency is just a digital assets which is based on blockchain technology and cryptography for any kind of digital transaction.
Cryptocurrency is a technological achievement but it is not in fully successful stage, it is in the developing stage.
in this slide, I am just focusing about what is cryptocurrency and how it works, that means how to buy, store, send and receive it and also I am discussing about the benefits and risks of the crypto currency.
The Bitcoin frenzy seems to have reached new heights lately, spurred by a growing user base, price volatility, and the rapidly evolving network of Bitcoin-related companies.1
Reports of big investments in "mining" equipment and the expanding ecosystem supporting the protocol remind us in many ways of a gold rush — an analogy made easier by Bitcoin's other similarities to the precious metal. It's hard to say whether this excitement is warranted, but it's equally hard to deny Bitcoin's increasing relevance to businesses and the broader economy.
Bitcoin, along with other cryptocurrencies, may have implications not only for the technology industry, where much of the current action is concentrated, but also other industries from retail businesses to financial services.
Read this paper to learn about Bitcoin in the context of the financial services industry, particularly payments and banks. What is it about this cryptocurrency that is inspiring such attention and what might the future of cryptocurrencies mean for traditional financial services?

There original abstract was as follows:
You've probably heard of Bitcoin, right? Bitcoin is original cryptocurrency which exploded in value in the last few months and paved the way for alt-coins such as Litecoin, Quark or Dogecoin. Currently, 1 bitcoin is worth nearly $1000, which left some of the original investors and miners, with thousands upon thousands of bitcoins, quite rich. Recently, even the Dogecoin community helped fund Jamaica's bobsled team to help go to the Sochi Winter Olympics by donating 30 million dogecoins, or roughly $30,000! What the hell is that all about? This talk aims to explain what cryptocurrencies are, how they work, and how they create value.
Here are some of the topics I intend on covering:
-the advantages of cryptocurrencies;
-the basics of the blockchain;
-how new blocks are mined using proof-of-work algorithms;
-how to mine using CPU, GPU or even ASIC miners;
-differences between Bitcoin's algorithm and scrypt-based alt-coins;

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.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

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.
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

3. Currency (n.):
Representative currency: deriving its worth from a
link to some physical store of value like gold, silver
or gemstones.
Fiat currency: Derives its value from the fact that a
government or central authority guaranteed it.
4. How to build a digital currency?
Requirements:
- Decentralized (Peer to peer)
- As anonymous as possible
- Fraud proof: No double spending, no theft
- Gradual availability of more currency, effort required
5. What is a hashing algorithm?
Hashing d7a8fbb307d7809469ca9abcb0082e4f8d5651e46d3cdb762d02d0bf37c9e592
File length: 12,322 bytes
7. How to build a digital currency?
The block chain: the innovative part of Bitcoin
The
genesis
block Dead
branch
8. Bitcoin – How the blocks in the blockchain are created
All transactions are logged in the blockchain (ledger)
All nodes (miners, clients in P2) have the full blockchain
New blocks are mined by the miners, who get a reward (first transaction)
New blocks are verified by all and refused if not valid
If you are miner, you must also process transactions – most earn a small
fee
9. Bitcoin – The network
Miners create blocks and process transactions
All the miners are connected to each other peer-to-peer
A Bitcoin client connects to the peer-to-peer network
Transactions are written into the blockchain
Confirmations are sent to the client
10. Bitcoin – Ways to do transactions
Currency exchanges like Mt Gox (EUR to BTC, BTC to EUR)
Local exchange (with other individuals)
Using your mobile phone
Unlimited – after all, you only need to exchange some data to do a
transaction
11. Bitcoin - Mining
How it works
Falling reward level
Technology rat race: cpu, gpu, asic
Profitability depends on BTC exchange rate, cost of electricity, cost of
hardware investment
12. Bitcoin (n.):
Not a representative currency, because it is not
linked to anything physical.
Not a fiat currency, as its supply is actually
finite and it lacks any central backing authority.
13. Bitcoin (n.):
Something new, only possible because of the Internet
and high-speed processing power of modern
hardware
Unforgeable, verifiable, secure, (almost) no
transaction fees, quasi-anonymous
Distributed, borderless
No trusted third party needed for transactions (bank)
14. Part two: Bitcoin and society
- Impact on government
- Context from privacy perspective
- Impact from real life events in Bitcoin (Cyprus,
Argentine)
16. Bitcoin - History
Created by “Satoshi Nakamoto”, an alias for the creator(s). Must be
mathematician(s) and programmer(s). Released a paper describing the
entire protocol in 2008.
2009-2010: First implementations of the miners. First transactions
achieved.
2011-2012: Wikileaks, EFF, Silk Road, 1000+ merchants accept BTC.
2013: Accidental fork of the blockchain, government starts regulating,
Coinbase and MtGox run out of trading capacity, exchange rate spikes to
$266
17.
18. Part three: Bitcoin and money
Making money with Bitcoin – how are people
doing it today?
Mining, rate speculation, currency exchanges,
casino’s, crime, payment processing, securities
exchanges.
19. Bitcoin – Has its own securities exchanges
MPEx, BitFunder, btct are Bitcoin denominated stock exchanges
Recent acquisition of a casino for 126315 BTC ($12.4 million
USD)
Companies on the exchange are mining companies, exchanges,
casino’s, etc. All Bitcoin related ventures.
The securities are priced, naturally in Bitcoin.
20. The first exit in Bitcoin
SatoshiDice acquired for 126,315 BTC (€8.69 million) on
July 18th.
Was trading publicly on MPEx, a Romanian Bitcoin
securities exchange.
21. Bitcoin – Startup investors are here and ready
Angel network BitAngels put together $7m from 120 angels
Boost VC in San Mateo has a incubator program for Bitcoin
startups
VC’s: Liberty City Ventures has $15m Bitcoin fund, Union Square
Ventures, Andreessen Horowitz have invested in Bitcoin startups.
French VC’s : on the beach
22. Bitcoin – follow up currencies are “altcoins”
Primecoin: the mining work results in discovery of new prime
numbers
PPCoin: Includes “Proof of stake”
Freicoin: Includes exploration of demurrage
