Sunstone Capital, Avalanche 2014 - Bitcoin: Primer, State of Play, DiscussionYacine Ghalim
Â
Every winter, Sunstone hosts an offsite event with the participation of executives from our portfolio companies, fellow VCs, and various thought leaders.
The event is designed to mix informal networking, stimulating discussions around key topics shaping our industry, and intense skiing. We find that the best inspiration and ideas are generated when you least expect it, and in company with people that challenge your thinking.
This year's edition took us to Courmayeur in the Italian Alps, and Bitcoin was on the list of topics we discussed. Here are the supporting slides from our Jan 24th presentation "Bitcoin: Primer, State of Play, Discussion".
http://www.sunstone.eu
Bit Coins are one most disruptive technologies in recent times with an impact that may ultimately be as big as the internet. Bitcoin uses peer-to-peer technology to operate with no central authority or banks. Managing transactions and the issuing of bitcoins is carried out collectively within a network. Bitcoin is open-source; its design is public, nobody owns or controls Bitcoin and anyone can take part. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system. Bitcoin is a virtual currency and the Bitcoin user experience will be very important for widespread adoption and use. In my talk I am going to talk about the evolution of currency, crypto currencies and Bit Coins. I will also discuss Bitcoin experiences and the Bitcoin platform eco-system, Bit Coin facts, and the possible future of Bit Coins.
Digital Currency Systems: Emerging B2B e-Commerce Alternative During Monetary...cjwells
Â
Digital currency systems form the triumvirate nexus of government policies, money, and technology. Each has a global reach and responds to the needs of business and consumers. E-commerce depends on private and government financial institutions to enable payment transactions, the basis of e-commerce. As the United States financial crisis continues B2B enterprises may need to abandon traditional payment transaction systems and look to alternatives in the form of Web-based digital currency systems accessed via the Internet. The various types of digital currency systems generally fit into five categories: barter exchange software systems, non-bank digital currency payment systems, digital precious metal systems, online value transfer software systems, and online stored value transaction software systems. Digital currency systems are not online banking. Digital currency systems use private electronic monies: electronic tokens, barter-exchange currencies, digital cash, and stored value e-cash vouchers.
We explore the history of money against a backdrop of banking and government policies that cause cyclic monetary crises, how these current digital systems operate, how business can thereby benefit in their use, and why digital currency systems are such an underutilized service in the United States.

Bitcoin is the world's first cryptocurrency, a form of electronic cash. It is the first decentralized digital currency: the system was designed to work without a central bank or single administrator.
Bitcoin price today BTC to USD market cap.pdfFranck La Rocca
Â
As of 4:11 p.m., the price of Bitcoin is $16,171.30, changing -2.19% from the previous day. The market capitalization of the tokens was $310,785,787,847.95 after the recent fluctuations in the price of bitcoin. Bitcoin has had a shift of -65.00% so far this year. According to the CoinDesks Digital Asset Classification Standard, Bitcoin is categorized as a currency (DACS).
Confused by some of the terms used on CoinDesk? Here you will find a complete bitcoin 101 that will help you to understand digital currency by explaining commonly used terms and their meanings.
Bitcoin â 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.
Bitcoin is a cryptocurrency. It is a decentralized payment system and kept alive due to the technology called Blockchain. These are peer-to-peer transactions. These transactions are verified by using a cryptography technology bank. Chain technology keeps the record of the distributed ledger. Bitcoins can be earned as a reward through mining. This currency can be convertible into other currencies, products, and services. Bitcoin has been emerging as a famous digital currency and popularity all over for quick transition. Moreover, bitcoin will be an economic asset because it has profitable results. The purpose of this research study is to explain the complete working of bitcoins technology, applications, and research challenges to be addressed, and the current future international market scope of Bitcoin technology.
Bitcoin was proposed by Satoshi Nakamoto on 31st Oct 2008. It is the pseudonym used by an individual or a collective group of people. In January 2009, the First open-source Bitcoin client was released and the bitcoin network came into existence. Satoshi Nakamoto is an inventor of bitcoin, and blockchain technology. All through itâs a false name. This is how he introduced himself to the internet. Unfortunately, many people think that because Satoshi Nakamoto has invented Bitcoin and the Blockchain technology, he is the owner of those too. The reality is that Satoshi Nakamoto has neither control over the Blockchain nor bitcoin. Therefore, it really doesnât matter who Satoshi Nakamoto is.
Blockchain is a technology, and its first function was on the platform named bitcoin. Bitcoin is Blockchain. However, Bitcoin itself is only a cryptocurrency that is capable of replacing fiduciary currency. Nevertheless, not that many people will like the idea at first.
What is Bitcoin and How is it related to Satoshi Nakamoto White Paper.pdfSuraj Sharma
Â
Well the terms like bitcoin & block chain are being coined and referred to everywhere over the internet or over any investment or financial platform the reason being its increasing popularity and the mammoth returns that people have made by investing in these avenues.
Although the concept of bitcoin is known to many but still there are many that are confronted with this question that what is a bitcoin and how does it work? so, in this blog I have made a sincere effort to explain the same in the easiest of manner for you to understand this concept. So as we move ahead we will dive in this concept of What is Bitcoin? How is it related to White paper of Satoshi Nakamoto? to understand the basics of bitcoins and how would its future be like.
The term crypto currency is being coined everywhere due to its increased popularity worldwide, it is being looked at with great aspiration to park oneâs money for a lucrative and manifold return. One can well imagine the return percentage on his/her investment in bitcoins by the fact that 1 bitcoin was worth $0 in 2009 and it now values at $55,353 (at the time of writing this article).
This means you could have been a millionaire or a billionaire if a reasonable investment was made in bitcoins in 2009 and was to be redeemed now.
Cryptocurrency- A Digital asset as a medium of exchange:
Crypto currency is a digital asset that is designed in such a manner that it offers the benefits of a medium of exchange like any other currency, so you can buy any item in exchange of these digital assets that you possess from the seller that accepts these forms of payments.
These digital assets are stored in computerized databases as they do not exist in physical form, using strong cryptography to secure the transaction records.
Decentralized Cryptocurrency Explained in Easy:
Whenever these digital currencies are minted, mined or created by the originator , the process is said to have exercised a centralized control, however when these are further disseminated to larger groups a decentralized control is said to have exercised. Each cryptocurrency functions through a distributed ledger technology that is typically known as block chain technology that serves as a public financial transaction database.
Although there are several other Cryptocurrencies that exist in the digital world and they too have offered good returns over a period of time, but the major issue involved in these digital currencies is that they are not backed by any of the apex bank of any country nor do they are traded in any banking channel.
Usually these digital currencies or cryptocurrencies that are not backed by any government or banking channel have no intrinsic value and nor do they will have in future.
Their values are derived purely on the basis of market forces of demand and supply and are a private fiat money. The market of these digital assets is highly volatile and have no capping on their price increase or decrease.
Bitcoin Technologyâ Bitcoin is an innovative technology that offers several benefits, such as fast transaction speeds, low costs, and the elimination of the need for a third-party intermediary to process transactions. Unfortunately, BitCoin has faced resistance from regulators because the technology has been used for nefarious purposes, including online drug purchases and Ponzi schemes. This note provides a basic explanation of how BitCoin works and is currently regulated on federal and state levels. This note argues that BitCoin should not be forced into old regulatory frameworks that do not adequately balance security concerns with the benefits of BitCoin. BitCoin should not be regulated at the federal level. Instead, state regulations should focus on BitCoin providers that can unilaterally transfer or block transfers of BitCoin on behalf of users. State regulators should require such providers to register with their given states, maintain adequate books and records, implement advanced cyber security standards, conduct audits of their operations, and submit reports to state regulators. In crafting these regulations, regulators should keep in mind that vague or poorly drafted regulations will chill innovation. A Bitcoin 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.
An overview of blockchain, cryptocurrencies, Bitcoin, Ethereum, ICOs. Meant to be introductory level but provide a slightly higher level of detail. Includes some companies to watch in the blockchain space. Prepared before the August 1 fork, which did occur.
Bitcoin is one of the famous and widely used decentralized currency in the world since it's creation. Here is the presentation on Bitcoin will help you understand more about it.
Hope this will help
Bitcoin is revolutionizing the way the world conducts transactions. It is the currency of the future. But what exactly is Bitcoin? In this slideshare, I break down the fundamentals of Bitcoin in a digestible manner. I touch on its advantages, structure, and potential. Even if you have no idea what bitcoin is before you start watching this, I can guarantee you will, once you're done.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
Â
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.

3. Bitcoin is a peer-to-peer electronic cash system.
First truly decentralized network for sending and receiving value over
the Internet.
It is a virtual currency that captures many aspects of security in its
requirements.
No one controls it. Bitcoins arenât printed, like dollars or euros â
theyâre produced by people, and increasingly businesses, running
computers all around the world, using software [bitcoin mining] that
solves mathematical problems.
Bitcoins
4. Cash - peer to peer
Electronic Cash -
Requires 3rd party trust
Every step adds cost
5. â Several âforksâ (modified versions) and derivative cryptocurrencies have
Satoshi Nakamoto invented the bitcoin
protocol, publishing a paper via the
Cryptography Mailing List in November
2008.
First version of the bitcoin software client
in 2009.
He/She participated with others on the
project via mailing lists, until he finally
began to fade from the community
toward the end. of 2010.
6. Milestones
October 2008 â Bitcoin design paper â Satoshi Nakamoto
January 2009 â Bitcoin v0.1 announced (software client)
May 2010 â Pizza purchased for 10,000 Bitcoins [1st real-world tx, $25 ->$5M]
July 2010 â Mt. Gox was established as a Bitcoin exchange market in Tokyo
by 2013 was handling 70%. Bankrupt in 2014 as $450M lost.
March 2013 â U.S. Treasury issues first regulatory guidance for virtual
currencies.
November 2013 â Federal regulators, including Bernanke, comment favorably
upon Bitcoin at the U.S. Senate hearing.
2015 :100,000 Merchants Worldwide including Facebook, Mozilla, Wikimedia
Spotify, Ryanair, Microsoft, Dell, and PayPal accepted Bitcoin
7. How Bitcoin Works?
It is a peer to peer network operated by a decentralized authority, unlike
government issued currencies.
Idea was to produce a currency independent of any central authority,
transferable electronically, more or less instantly, with very low transaction
fees.
You can set up a bitcoin address in seconds, no questions asked, and with
no fees payable. BTC to BTC tx are technically free*.
Users can hold multiple bitcoin addresses, and they arenât linked to names,
addresses, or other personally identifying information
8. How Bitcoin Works?
Bitcoin stores details of every single transaction that ever happened in the
network in a huge version of a general ledger, called the blockchain.
If you have used bitcoin address, anyone can tell how many bitcoins are
stored at that address. They just donât know that itâs yours.
There are no bitcoins, only records of bitcoin transactions. They donât exist
anywhere, even on a hard drive. Instead, there are only records of
transactions between different addresses, with balances that increase and
decrease.
Bitcoin miners verify the transaction and processes it.
9. How are bitcoins sent?
You need two things: a bitcoin address and a private key.
A bitcoin address is generated randomly, and is simply a 32 character
sequence of letters and numbers.
1BWEgGNEj2ED9SyyvXqH3wWiphFMczM1Uy
The private key is another sequence of letters and numbers, but unlike your
bitcoin address, this is kept secret.
Bitcoin addresses are derived from the hash of the public key, paired with
your private key
2^160 addresses & 2^96 private keys possible for each address
10. How are bitcoins sent?
A transaction is sent by signing a message with
1. The input, source transaction(s) of the coins
2. Amount
3. Output (Receiver's address).
This information will be made into a transaction.The bitcoin network deals
collects all of the transactions made during a set period into a list, called a
block. Minerâs confirm those transactions, and write them into a general ledger,
the blockchain.
11. Hashing

SHA256 was used like in bitcoins
14. A cryptographic system that uses two keys -- a public key known to everyone and
a private key (secret key) known only to the sender of the message.
Each coin is associated with its current owner's public key, hashed to form
bitcoin address.
When you send some bitcoins to someone, you create a transaction, attaching the
new owner's public key to this amount of coins, and sign it with your private key.
When this transaction is broadcast to the bitcoin network, this lets everyone know
that the new owner of these coins is the owner of the new key.
Your signature on the message verifies for everyone that the message is
authentic. The complete history of transactions is kept by everyone, so anyone
can verify who is the current owner of any particular group of coins.
Public Key Cryptography in bitcoin
15. Computational complexity in bitcoin
The hash of a block (block header) must start with a certain number of zeros.
The probability of calculating a hash that starts with many zeros is very low,
therefore many attempts must be made.
Any change to the block data (such as the nonce) will make the block hash
completely different. Many different nonce values are tried, and the hash is
recomputed for each value until a hash containing the required number of zero
bits is found. The hashing is based on the hashcash function.
The number of zero bits required is set by the difficulty. As this iterative calculation
requires time and resources, the presentation of the block with the correct nonce
value constitutes proof of work.
16. Bitcoin mining
Minersâ confirm the transactions, and write the
block into the blockchain.
Blockchain contains an increasingly lengthy
list[append-only] of all the transactions [verified &
valid] that ever took place on the bitcoin network.
A constantly updated copy of the block is given to
everyone who participates (mining), so that they
know what is going on.
New transactions are constantly being
processed by miners into new blocks which are
added to the end of the chain and can never be
changed or removed once accepted by the
network
17. How are transactions verified ?
The main data structures in the bitcoin network are transactions and blocks.
Blocks are composed of the block header followed by transactions in the
block. Transactions & Blocks are identified by their hash value.
A miner chooses a list of transactions from a pool of unconfirmed transaction.
The miners work on them to "solve" the block and once a block is "solved",
it is broadcast to the network, and all the transactions in the block becomes
confirmed.
Miners only include tx that don't break the rules*. The rules include checking
that the inputs are valid, that a coin isn't double-spent, that the output isn't
more than the input, etc. When a miner generates a block with an invalid
transaction on top of a valid block, other miners will not accept the new block.
* Bitcoin Protocol rules
18. How are Bitcoins generated [mined] ?
The creation of coins must be limited for the currency to have any value.
Bitcoins are slowly mined into existence by following a mutually agreed-upon set of
rules. A user mining bitcoins is running a software program that searches for a
solution to a very difficult math problem the difficulty of which is precisely known.
When a solution is found, the user may tell everyone of the existence of this newly
found solution by relating the block. The solution itself is a proof-of-work or PoW.
It is hard to find, but easy to verify.
19. How are Bitcoins generated [mined] ?
Blocks create 12.5 new bitcoins at present [October 2016].
block reward - incentive for people to perform the computation work required for
generating blocks.
Roughly every 4 years, the number of bitcoins that can be "mined" in a block
reduces by 50%. Principle of Controlled supply, Quantitative easing applies etc
here to some extend. The Bitcoin generation algorithm defines, in advance, how
currency will be created and at what rate.
Originally -> 50 bitcoins November 2012 -> 25 July 2016 -> 12.5.
In the end, no more than 21 million bitcoins will ever exist, but not necessarily
spendable.
21. Who/what decides value of Bitcoin ?
Bitcoinâs price is measured against fiat currency, such as American Dollars
(BTCUSD), Chinese Yuan (BTCCNY) or Euro (BTCEUR).
Unlike fiat currencies however, there is no official Bitcoin price; only various
averages based on price feeds from global exchanges.
Demand & Supply - Price discovery occurs at the meeting point between demand
from buyers and supply of sellers. Majority of supply is controlled by early adopters
and miners, capped at 21 Million
Supply - Miners currently produce around 3,600 bitcoins per day, some portion of
which they sell to cover electricity and other business expenses.
22. Who/what decides value of Bitcoin ?
Demand - Current mining reward is 12.5 BTC per block solution, Bitcoin supply is
inflating at around 6.25% annually.
That Bitcoinâs price is rising despite such high inflation indicates extremely
strong demand. Every day, buyers absorb the thousands of coins offered by
miners and other sellers.
Demand is commonly monitored by
Google trends data (from 2011 to the present) for the search term âBitcoin.â
High levels of public interest may exaggerate price action; media reports of
rising Bitcoin prices draw in greedy, uninformed speculators, creating a
feedback loop.
23. Who/what decides value of Bitcoin ?
Banking Blockades - first such instance was the late 2010 WikiLeaks banking
blockade, whereby VISA, MasterCard, Western Union and PayPal ceased
processing donations to WikiLeaks.
Darknet drug markets - a commercial website on the dark web that operates
via darknets such as Tor or I2P. They function primarily as black markets,
selling or brokering transactions involving drugs, cyber-arms, weapons,
counterfeit currency, stolen credit card details, forged documents,
unlicensed pharmaceuticals,steroids,other illicit goods as well as the sale of
legal products.
24. Who/what decides value of Bitcoin ?
Fiat Currency Crises - Bitcoin wallet can be a lot safer than a bank
account. Eg In Greece, strict capital controls were imposed in 2015. daily
withdrawal limit of âŹ60.
After the Greek crisis, China began to devalue the Yuan. As reported
at the time, Chinese savers turned to Bitcoin to protect their
accumulated wealth.
Bitcoin is ultimately worth what people will buy and sell it for.
Bitcoin rose to a high of $737 following the US election results, up
from its $707 price when the market closed yesterday.
25. Who/what decides value of Bitcoin ?
Bitcoinâs value is determined by perception. Instead of the trust (govt)
other factors (the technology, widespread acceptance, understanding of e-
money, etc.) are taken into consideration.
When magazines and online entities write intriguing articles about Bitcoin,
people take interest in it, the demand goes up and so does its value.
Likewise when Mt. Gox is DDoSed, a bitcoin service shutters, or
$250,000 worth of BTC is stolen, people get nervous, demand drops, and
so does BTC's value.
32. Are bitcoin transactions 100% free ?
For a long time in Bitcoinâs existence, miners processed transactions without
fees. All miners today expect transactions to include fees due to the overall
volume of the network and to avoid spamming of the Bitcoin network.
Also because the block reward will decrease over the long term, miners will
some day instead pay for their hardware and electricity costs by collecting
transaction fees. Or hypothetically after 21 million bitcoins are mined (in 2144*).
The sender of money may voluntarily pay a small transaction fee which will
be kept by whoever finds the next block. Paying this fee will encourage miners
to include the transaction in a block more quickly.

* Bitcoin reward schedule
33. How long does a bitcoin transaction take ?
Your transaction must be verified by miners. So you are sometimes forced to
wait until they have finished mining. The bitcoin protocol is set* so that each
block takes roughly 10 minutes to mine [few seconds to upto 90 minutes]
Some merchants may make you wait until this block has been confirmed,
whereas some merchants wonât make you wait until the transaction has been
confirmed. They effectively take a chance on you, assuming that you wonât try
and spend the same bitcoins somewhere else before the transaction confirms.
This often happens for low value transactions, where the risk of fraud isnât as
great.
* Mining difficulty
34. How long does a bitcoin transaction take ?
Receiving notification of a payment is almost instant with Bitcoin. However,
there is a delay before the network begins to confirm your transaction by
including it in a block.
A confirmation means that there is a consensus on the network that the
bitcoins you received haven't been sent to anyone else and are considered
your property.
Once your transaction has been included in one block, it will continue to be
buried under every block after it, which will exponentially consolidate this
consensus and decrease the risk of a reversed transaction. Every user is free
to determine at what point they consider a transaction sufficiently confirmed,
but 6 confirmations is often considered to be as safe as waiting 6 months on a
credit card transaction.
35. Bitcoin nodes/network
In order to validate and relay transactions, bitcoin requires more than a network of
miners processing transactions, it must broadcast messages across a network
using 'nodes'. This is the first step in the transaction process that results in a
block confirmation.
A node is a machine with Bitcoin core client installed with the complete block
chain. The more nodes there are, the more secure the network is.
Unlike bitcoin mining, where participants are rewarded for confirming transactions,
running a bitcoin node does not provide any incentive. The only benefit for
someone to run a node is to help protect the network

39. Is Bitcoin legal?
Bitcoin is NOT illegal* by legislation in most jurisdictions at present**. Although it is
also being used for illegal purposes; similar to technologies like Internet (copyright
violations etc).
Some jurisdictions (such as Argentina and Russia) severely restrict or ban foreign
currencies. Other jurisdictions (such as Thailand) may limit the licensing of certain
entities such as Bitcoin exchanges.
Regulators from various jurisdictions are taking steps to provide individuals and
businesses with rules on how to integrate this new technology with the formal,
regulated financial system. For example, the Financial Crimes Enforcement
Network (FinCEN), US.
** Was illegal in Russia & Thailand in past

40. Has Bitcoin been hacked in the past?
The rules of the protocol and the cryptography used for Bitcoin - NO
There are often misconceptions about thefts and security breaches that happened
on diverse exchanges and businesses. None of them involve Bitcoin itself being
hacked, nor imply inherent flaws in Bitcoin; just like a bank robbery doesn't mean
that the dollar is compromised.
A complete set of good practices and intuitive security solutions is needed to give
users better protection of their money, and to reduce the general risk of theft and
loss.
Bitcoin protocol itself may be secure, the wallets and services used to store
and exchange Bitcoin may not.
42. Hypothetically, if a single entity contributed the majority of the networkâs mining
hashrate(processing power), they would have full control of the network and
would be able to manipulate the public ledger (blockchain) at will.
Mining pools - groups of bitcoin miners who pool their resources & share their
rewards
Ghash.io (mining pool) has twice come dangerously close to obtaining 51% of the
bitcoin network's hashing power. In October, 2016, GHash.IO pool has been
closed.
At current network mining difficulty levels, not even large-scale governments could
easily mount a 51% attack.
51% attack

44. Bitcoin Wallet
Without a wallet, you canât receive, store, or spend
bitcoins easily.
Bitcoin wallets contain private keys; secret codes
that allow you to spend bitcoins.
In reality, itâs not bitcoins that need to be stored and
secured, but the private keys that give you access
to them.
Wallets can be s/w, h/w, paper wallet, Rings etc.
Nowadays Apps, websites store it for you & you
won't be seeing your private keys.

50. Other Cryptocurrencies (Altcoins)
The word âaltcoinâ is an abbreviation of âBitcoin alternative,â and thus describes
every single cryptocurrency except for Bitcoin.
Altcoins are referred to as Bitcoin alternatives because, at least to some extent,
most altcoins hope to either replace or improve upon at least one Bitcoin
component.
A cryptocurrency must have some of the following qualities:
The currency must have a market cap of one million US dollars.
The currency must be the first to introduce an innovative protocol.

51. Why do people trust Bitcoin? - The Blockchain
Much of the trust in Bitcoin comes from the fact that it requires no trust at all.
Bitcoin is fully open-source and decentralized. This means that anyone has
access to the entire source code at any time. Any developer in the world can
therefore verify exactly how Bitcoin works.
All transactions and bitcoins issued into existence can be transparently
consulted in real-time by anyone.
All payments can be made without reliance on a third party and the whole
system is protected by heavily peer-reviewed cryptographic algorithms like those
used for online banking.
No organization or individual can control Bitcoin, and the network remains secure
even if not all of its users can be trusted.
52. The blockchain is a global distributed ledger, which facilitates the
movement of assets across the world in seconds, with only a minimal
transaction fee. These assets can be any type of value, as long as they
can be represented digitally.
