Bitcoin is an experimental digital currency that operates on a decentralized peer-to-peer network. It was created in 2009 by the pseudonymous developer Satoshi Nakamoto. The presentation provided an overview of how bitcoin works, including how transactions are broadcast on the network and incorporated into blocks, how miners compete to validate transactions and are incentivized with bitcoin rewards, and how the blockchain records and stores all transactions. While bitcoin aims to increase security, reduce costs and remove governments from money supply, the presentation noted flaws in capping the money supply and lack of governance could undermine it. Predictions were made that technology and adoption will continue to evolve but governments may intervene and deflation is not a problem if used alongside fiat currencies
Bitcoin is a digital currency created in 2008 that allows for fast and relatively free transactions anywhere in the world. It uses cryptography and a decentralized network to verify transactions and create new bitcoins. The value of bitcoin comes from its usefulness as a currency and the demand for it. However, bitcoin is still experimental and volatile, with an uncertain future in terms of stability, regulation, and widespread adoption. The bitcoin community continues to develop the software, payment systems, and applications around this new currency.
This document provides an overview of Bitcoin, the world's first cryptocurrency. It discusses how Bitcoin aims to decentralize key functions like identity, accounting, truth, and issuance through a distributed peer-to-peer network. It notes that Bitcoin achieves decentralization by basing truth on the largest amount of computational power via a "1 CPU, 1 vote" system. The document also provides estimates of the hashing power and costs required to attack the Bitcoin network and examines how an economy is developing around Bitcoin through services and trade.
This document provides an introduction to bitcoin, including what it is, how it works, advantages, disadvantages, weaknesses, history, data, mining process over time, physical representations, and future possibilities. Bitcoin is described as a decentralized digital currency based on cryptography, without a central authority. Transactions are confirmed by miners who are rewarded with new bitcoins. Key aspects covered include how users can send and receive bitcoins, security issues, increasing difficulty of mining over time, and the currency's value and adoption over its history.
Blockchain and applications is a masterclass with a range of concepts around blockchain, cryptocurrencies and useful applications for the technology.
From Bitcoin to Ethereum, how a blockchain works, what is a smart-contract, what applications can be built on top of different technologies ant protocols.
Cryptocurrencies like Bitcoin and Ethereum have exploded in popularity due to various socioeconomic factors and their advantages over traditional currencies. Their underlying blockchain technologies use cryptographic techniques like hashing and Merkle trees to manage trust in a decentralized manner without the need for centralized authorities. Miners are incentivized to secure the networks by verifying transactions for a reward of new coins, though over time the rewards are reduced according to set algorithms to control inflation. Anyone can now create new cryptocurrencies by forking existing blockchains or launching new ones.
Bitcoin – for some people, this may be something making them excited and sleepless while for some others, it may be the first time they have come across such a term.

Crypto Think Tank Presentation on Alternative Cryptocurrency Feb 16, 2014 at ...cryptothinktank
The document discusses the current landscape of alternative cryptocurrencies or altcoins. It outlines that there are currently over 100 altcoins listed, with Litecoin being the most popular and second largest after Bitcoin. Altcoins use different hashing algorithms like SHA for Bitcoin versus scrypt for Litecoin. Mining adjusts difficulty to maintain block generation times and can be done using CPUs, GPUs, FPGAs or ASICs. The future of altcoins is uncertain but a few may survive based on their purpose, popularity and resistance to regulation and centralization of mining hardware.
Bitcoin is a cryptocurrency that was created in 2009 as a decentralized digital currency not controlled by any central authority like a bank. It uses cryptography to secure transactions and generate new units of currency. Transactions are recorded on a public ledger called the blockchain. New bitcoins are "mined" by solving complex math problems, and the total number that can ever be created is limited to 21 million. While bitcoin offers advantages like instant transactions and anonymity, it also has risks like high volatility and the inability to recover funds if private keys are lost.

Bitcoin - An introduction to a decentralised and anonymous currencyAndyBrodieLocima
A very short overview of Bitcoin, how it works and why it works. Starting with a definition of what a currency is, how Bitcoin relates to that definition and a bit of history, this presentation covers how Bitcoin transactions, blocks, blockchains and mining work.
A Crypto currency is a digital or virtual currency.
Many crypto currency are decentralized networks based on block chain technology – a distributed ledger enforced by a disparate network of computers.
SATOSHI NAKAMOTO
S.N is the name used by the person or persons who developed bitcoin, authored the bitcoin white paper, and created and deployed bitcoin’s original reference implementation.
A block chain is a distributed database that is shared among the nodes of a computer network. As a database, a block chain stores information electronically in digital format. systems, such as Bitcoin, for maintaining a secure and decentralized record of transactions. The innovation with a block chain is that it guarantees the fidelity and security of a record of data and generates trust without the need for a trusted third party.
as well as in a modern world the crypto currency is use full to make a transactions secretly. Now many governments can accept this currency. But this currency is an decentralized system.
Bitcoin is a digital currency that allows for peer-to-peer transactions without an intermediary. The document discusses how bitcoin works, including how transactions are recorded in a public ledger called the blockchain and secured through cryptography. It also describes how bitcoin can be acquired, stored in digital wallets, and exchanged at bitcoin ATMs or exchanges. While bitcoin offers advantages like low fees and censorship resistance, it also faces challenges like volatility, lack of buyer protection, and limited acceptance.

Bitcoin is a digital currency created in 2008 that allows for electronic transactions without a central bank or single administrator. It can be used to buy goods and services from participating retailers. Bitcoin transactions are verified by a decentralized network of computers and recorded in a public ledger called the blockchain. While it offers advantages like low fees and anonymity, bitcoin also faces risks like high volatility, the possibility of losing coins if private keys are lost, and lack of legal protections and central oversight. Regulators in some countries have issued warnings about bitcoin's risks.
Cryptocurrencies like Bitcoin aim to enable digital cash transactions that are secure, private, and preserve users' anonymity. Bitcoin introduced a decentralized digital currency using cryptography and a peer-to-peer network to validate transactions without a central authority. It uses public key cryptography, digital signatures, and cryptographic hash functions to secure transactions and prevent double spending. While Bitcoin provides pseudonymity, all transactions are recorded on the public blockchain, compromising users' privacy. Zerocoin was developed to add an anonymous currency on top of Bitcoin using zero-knowledge proofs to allow users to exchange bitcoins for untraceable zerocoins and back without revealing their identities.
This document provides an overview of Bitcoin, including:
- Bitcoin is the world's first decentralized digital currency, with no central authority.
- It uses cryptography and a peer-to-peer network to allow users to send and receive money anywhere in the world without third party intermediaries.
- The blockchain records all Bitcoin transactions in a growing list of blocks to prevent double-spending and determine the legitimate owner of coins.
The document discusses Bitcoin, a cryptocurrency. It begins by explaining how Bitcoin started as a concept in 2009 and was described in a paper by Satoshi Nakamoto. It then discusses how Bitcoins are created through mining computations and outlines some of the benefits of Bitcoin like being an international currency without transaction fees. However, it also notes issues like Bitcoin exchanges being targets for hacking and countries restricting or outlawing its use.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Threats to mobile devices are more prevalent and increasing in scope and complexity. Users of mobile devices desire to take full advantage of the features
available on those devices, but many of the features provide convenience and capability but sacrifice security. This best practices guide outlines steps the users can take to better protect personal devices and information.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

2. FBI WARNING
The following presentation should be
considered ฿ullshit. The presenters are
not financial advisers. Please consult a
professional before investing your money
in Bitcoin or any other money laundering
scheme.
With any talk that involves money, a warning is always apt.
3. FBI WARNING
One of the presenters is a hardcore
capitalist and doesn’t like change, the
other is more reasonable.
I’ll be presenting the facts and Colin will
be presenting the ฿ullshit.
Zach: I have my own warning too!
9. Fiat Currency
Fiat Currency is issued by governments to pay taxes
Worth something because, by law, it must be accepted as a payment of debt.
Therefore people trust that if they have money, by law, they can trade it for goods.
10. And really, it’s run by men like these:
Mark Carney - Bank of Canada
Ben Bernanke - US Federal Reserve
11. bitcoin: We can do better
• Increase security while simplifying infrastructure overhead
• Reduce transaction costs
• Make transactions as fast as the internet
• Remove government from money supply
• Stabilize money supply to address inflation

this is done both as a way of introducing new BTC and securing the network
28. this is what mining hardware looks like...
mining is performed by powerful computers
incentives to be the fastest miner have driven efficiency enhancements
from CPU to GPU to FPGA and soon ASIC

• The only way new BTC enter circulation
• Difficulty is adjusted to ensure 1 block / 10 minutes
• Confirms transactions
• Prevents double spending
• Nakamoto compared this process to gold miners expending
resources to add gold to circulation.
39. What’s in it for miners?
• 50 BTCs for each discovered block (declining over time)
• Transaction fees paid by users

There is a cap to the amount of bitcoin currency in the system
The reward for mining will go down over time; revenue to be augmented by transaction volume
42. Total Revenue to Miners
General trend is that miners are making more money each day.
consider that there is a rate limit of max 1 block every 10 min, the overall gross revenue for each block is going up.
43. How is it doing?
A+ • Increase security while simplifying infrastructure overhead
A • Reduce transaction costs
A • Make transactions as fast as the internet
• Remove government from money supply
• Cap money supply to address inflation
bitcoin is cool.
44. Governance is the byproduct of
government monetary policy
But there are some dark sides of bitcoin: the lack of governance
* allows extortion from organizations like Russian Business Network
* allows Money Laundering
* and Ponzi schemes (Bernard Madoff shown here)
* and also allows the grayer areas like Silk Road
45. How is it doing?
A+ • Increase security while simplifying infrastructure overhead
A • Reduce transaction costs

C+ • Remove government from money supply
? • Cap money supply to address inflation
49. Humans are predisposed to growth
humans like growth
social evolutionary theory: hunter-gather to agrarian; shift value from quantity to quality
50. Our economy is built on growth
economy is built on the assumption of growth.
“buy low, sell high” mantra
Growth leads to efficiencies and inc. productivity
Fueled by growth of the population, growth in efficiencies and growth of earning power

isn’t the economic growth artificial because we are pumping money in the system?
No.
example: community of 10 people;
10 bitcoins each (100 total);
community grows 2x but still only 100 bitcoins in circulation;
prices have to go down.
52. The real story is about
standard of living
no.
add currency to compensate for growth; ensure that earning power doesn’t decrease
the truth: earning power is going up;
The Achilles heal of the system: limited money supply scarcity, hoarding, mattress’ing
To compensate: add money supply added at a steady rate while also encourage monetary liquidity
No one wants their buying power to go down
No one wants their wages to go down
53. Humans again are
the problem:
emotionally driven
Supply can be pumped in
consumer spending is a purely emotionally driven function
* the happier we feel
* the more we spend
* the more liquidity in the market
* the less inflation (monetary devaluation)
Achilles heal: no spending; example: small town
54. GDP = C + I + G + (X-M)
+ + +
formulas that will kill the mood at a dinner party
4 big levers usually used to keep liquidity; ensure price increases don’t rise too quickly:
spend your own money
give the banks so they can invest;
government spends (eg: ‘new deal’) to artificially cause liquidity
more imports > exports; what about a global economy

Over the last 30 years we’ve figured this thing out this experiment
economics is like flying an airplane using the rear-view mirror.
Overall, we know how to adjust the right levers (G vs. i vs. C)
56. How is it doing?
A+ • Increase security while simplifying infrastructure overhead
A • Reduce transaction costs
A • Make transactions as fast as the internet
F • Remove government from money supply
F • Cap money supply to address inflation
For this reason, I think bitcoin is flawed.
caping the money supply will be the undoing of bitcoin
57. ฿ bitcoin: crossing the chasm
• Growth: uncapped potential for money supply
• Governance: don’t let the bad guys win
• Government: or algorithms that can stimulate a currency
• Greenback: technology for daily adoption
Early Adopters Pragmatists Conservatives Laggards
58. Predictions & Prognostications
Colin
Technology is cool
ideology is flawed
questions about scalability
Banking could benefit from the algorithms
Zach
Reminds me of early days of internet (Hype + Skepticism = both were right + evolution)
Will see volatile prices for a while
Expect governments to intervene good? bad? - some governance okay
Needs its Mosaic/Netscape moment - current apps work but have terrible UX
If this happens... expect $100/BTC within 5 years
Deflation is not a problem - don’t expect BTC to replace Fiat - ebooks didn’t replace paper
Gold is hoarded, therefor deflationary, you can exchange gold for USD, no problems right?
Expect more rapid adoption in 3rd world accompanied by cell phone growth / lack of infrastructure.
Reduced friction in moving money around = more global collaboration / distributed ventures => GOOD
60. How do I get my own bitcoins?
• Mine them yourself
• Buy them at an exchange:
• http://bitcoincharts.com/ - 50+ active markets
• I use https://www.cavirtex.com/
• Buy them at Wallmart, 7-11 !
• 700,000 locations - bitinstant.com/cashpayment.com
