State of the bitcoin address, Pizza, Pirates, and Profiteers: The Bitcoin has come a long way in its first 4 years as a crypto currency. Bursting bubbles and resurgence, the bitcoin has comeback to a greater acceptance and wider audience than ever before, breaking all time highs with prices in the $90+ range. This talk will cover everything you NEED to know about bitcoin, from a consumer and manufacturer standpointAcquisition to Spending (including mining crypto currencies and the future of mining) Staying secure anonymous with bitcoin, the infrastructure behind bitcoin, and the things you can do with bitcoin.

What is a crypto currency?

Cryptographic currencies are currencies represented by units of complex cryptographic math problems.

What is Bitcoin?

What is Bitcoin? Bitcoin is many parts of a whole. not only is it a a new kind of digital currency. It's the first decentralized digital peer to peer crypto currency not regulated or controlled by a single organization, government, person or entity. It is also a complex peer to peer network. The network or blockchain helps regulate scarcity, and market stability. Bitcoin is completely decentralized, with no central server or trusted parties, because everything is based on crypto proof instead of trust. Bitcoin dose not rely on any physical note or representation.

In many ways, bitcoins function essentially like any other currency, and are accepted as payment by a growing number of merchants, both online and in the real world. Bitcoins are generated at a predetermined rate by an open-source computer program, which was set in motion in January of 2009. This program produced each one of the nearly eleven million bitcoins in circulation (with a total value just over a billion dollars at the current rate of exchange), and it runs on a massive peer-to-peer network of some twenty thousand independent nodes, which are generally very powerful (and expensive) G.P.U. or ASIC computer systems optimized to compete for new bitcoins.

Bitcoin releases a twenty-five-coin (originally 50 bitcoins) reward to the first node in the network that succeeds in solving a difficult mathematical problem requiring a certain amount of brute-force computation (known as a proof-of-work calculation.) The solution is then broadcast throughout the network, and competition for a new block and its twenty-five-coin reward begins.

At first, anyone armed with an ordinary computer could download and run the Bitcoin software and gather (or “mine”) bitcoins. The more computing power you can dedicate to Bitcoin calculations, though, the better your chances of arriving first at each solution. This feature of the system, by design, resulted in a kind of computational arms race that strengthened the network by rewarding increased computing power. Four years into the Bitcoin project, only very powerful, purpose-built machines have enough muscle to keep pace with existing network nodes.

In this way, bitcoins are mined like gold used to be, in quantities that are small relative to the total supply, so that the supply grows slowly. There is an upper limit of twenty-one million new coins built into the software; the last one is projected to be mined in 2140. After that, it is presumed that there will be enough traffic to keep rewards flowing in the form of transaction fees rather than mining new coins. For now, the bitcoins are initially issued to the miners, but are distributed when miners buy things with them or sell them to non-miners

How does Bitcoin work?


What is a blockchain?

Where are Bitcoins stored?

In order to work with Bitcoin a wallet is a requirement. It's probably the safest to use a full Bitcoin client like the official one. However when just started out with small amounts you might choose security over ease of use.

    • Blockchain.info; hosted online wallet. Create when just getting started, the added benefit is that you can deposit money via Bank/Mobile to fund your account right away.
    • Electrum; a thin client. Like the Blockchain wallet this uses a remote server to retrieve the transaction data. Once installed you can start working with Bitcoin immediately.
    • Original Bitcoin client; the original or "reference" client. It takes a while to get started with this client since it needs to download all the transactions before you can actively use it.

Who made bitcoin

In 2008, Satoshi Nakamoto, the founder of Bitcoin, whose real identity is not known, cleverly combined existing peer-to-peer network technologies, cryptographic techniques, digital signatures, and the potential power of network effects to design and develop the Bitcoin system. Nakamoto was very clearly motivated in this effort by the fallout from the 2008 financial crisis. When the experiment was launched and the first fifty bitcoins (the so-called genesis block) were mined, in January of 2009, he (or she, or they) included this line of text along with the data: “The Times 03/Jan/2009 Chancellor on brink of second bailout for banks.”

Until his disappearance from the Web, around the spring of 2012, Nakamoto was a visible participant on cryptography forums, where he discussed Bitcoin freely, and published a nine-page paper outlining the details of the project. These posts reveal that even in 2008, Nakamoto was able to respond to concerns regarding the scalability of bitcoin with remarkable prescience; he clearly understood the ramp-up of computing power that would be required for producing bitcoins as the system grew.

   Only people trying to mine new coins need to run network nodes And at first, most users ran network nodes, but as the network grew beyond a certain point, mining increasingly became the domain of specialists with server farms of specialized hardware.

A casual review of Nakamoto’s various blog posts and bulletin-board comments also confirms that, from the first, Bitcoin was devised as a system for removing the possibility of corruption from the issuance and exchange of currency. Or, to put it another way: rather than trusting in governments, central banks, or other third-party institutions to secure the value of the currency and guarantee transactions, Bitcoin would place its trust in mathematics. At the P2P Foundation, Nakamoto wrote a blog post describing the difference between bitcoin and fiat currency:



Bitcoin Wallets

Use of the phrase "Official Bitcoin Client"

For reference, I would avoid using this phrase to describe the client available at Bitcoin.org and instead use a more accurate substitution such as "Bitcoin Reference Client", "BitcoinQT Client", or the "Original Bitcoin Client". Bitcoin.org uses both of the latter two.

Getting Bitcoin

There are tons of options of getting Bitcoin. Here are a couple of solutions if you have a better solution for a certain region please let me know.

Inside the US

  • Coinbase

Coinbase wants to be the Paypal for Bitcoin. Just hook up your bank account and you can instantly exchange Bitcoin.

  • Bitinstant

BitInstant enables you to make local cash deposits for Bitcoin. Just go down to wallmart for instance and have your Bitcoin in your account without problem. There is also an option to deposit using Dwolla.
