  18. 18. Okay, so what is bitcoin about?

  20. 20. Basic Concepts I Blockchain The blockchain is a shared public transaction log on which the entire Bitcoin network relies. All confirmed transactions are included in the blockchain with no exception. This way, new transactions can be verified to be spending bitcoins that are actually owned by the spender. The integrity and the chronological order of the blockchain are enforced with cryptography.
  21. 21. Basic Concepts II Transaction A transaction is a transfer of value between Bitcoin addresses that gets included in the blockchain. Bitcoin wallets keep a secret piece of data called a private key for each Bitcoin address. Private keys are used to sign transactions, providing a mathematical proof that they come from the owner of the addresses. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast between users and confirmed by the network in the following minutes, through a process called mining. Image courtesy of
  22. 22. Basic Concepts III Nonce The "nonce" in a bitcoin block is a 32-bit (4-byte) field whose value is set so that the hash of the block will contain a run of zeros. The rest of the fields may not be changed, as they have a defined meaning. Any change to the block data (such as the nonce) will make the block hash completely different. Since it is believed infeasible to predict which combination of bits will result in the right hash, 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. As this iterative calculation requires time and resources, the presentation of the block with the correct nonce value constitutes proof of work.
  23. 23. Basic Concept IV Mining "Winning" the next bitcoin in a chain means happening upon a bitstring, or nonce, that when combined with the data in the chain so far, produces a SHA-256 hash with a certain number of leading zeros. The probability of finding such a pattern by chance - and there is no better way known - is 1/2z , where z is the number of needed zero bits. The Bitcoin protocol estimates the amount of CPU power currently in the Bitcoin mining network, and continually adjusts z so that, on average, one successful solution turns up every ten minutes. Each successful solution is currently worth 25 bitcoins Mining is a distributed consensus system that is used to confirm waiting transactions by including them in the blockchain. It enforces a chronological order in the blockchain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network. These rules prevent any previous block from being modified because doing so would invalidate all following blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively in the blockchain. This way, no individuals can control what is included in the blockchain or replace parts of the blockchain to roll back their own spends.

  35. 35. Mining is a hard day's work it would statistically take you 40 years with a normal CPU to find out one winning ticket of hashes and nonces. Coal miner Lee Hipshire in 1976, shortly after emerging from a mine in Logan County, W.Va. at the end of his shift. At age 36, he had worked 26 years underground. A few years later, Lee took early retirement because of pneumoconiosis, or black lung disease. He died at 57.

  36. 36. Just a little help of my friends (Pooled mining is a mining approach where multiple generating clients contribute to the generation of a block, and then split the block reward according the contributed processing power. Pooled mining effectively reduces the granularity of the block generation reward, spreading it out more smoothly over time.

  41. 41. bitcoin and Capitalism
  42. 42. Welcome to the Darkside! The Ponzi Scheme (or why are there so many exiled princes in Nigeria sending me emails) A Ponzi scheme is a fraudulent investment operation that pays returns to its investors from their own money or the money paid by subsequent investors, rather than from profit earned by the individual or organization running the operation. The Ponzi scheme usually entices new investors by offering higher returns than other investments, in the form of short-term returns that are either abnormally high or unusually consistent. Perpetuation of the high returns requires an ever-increasing flow of money from new investors to keep the scheme going. http://en.wikipedia. org/wiki/Ponzi_scheme
  43. 43. Recycling Debt or The Roots of Crisis "Finance capitalism has become a network of exponentially growing interest-bearing claims wrapped around the production economy. The internal contradiction is that its dynamic leads to debt deflation and asset stripping. The economy is turned into a Ponzi scheme by recycling debt service to make new loans to inflate property prices by enough to justify yet new lending."

  46. 46. Nixon Shock (...or why I am not backed by gold anymore (although I never was since I printed more money than the system produced), but by the fiat, the trust markets have in lending money to different governments.) To prevent a run on the dollar, stabilize the economy, and decrease unemployment and inflation rates, on August 15, 1971, Nixon issued Executive Order 11615, pursuant to the Economic Stabilization Act of 1970, which imposed a 90-day maximum wage and price ceiling, a 10% import surcharge, and, most importantly, "closed the gold window", ending convertibility between U.S. dollars and gold. The President and fifteen advisers made that decision without consulting the members of the international monetary system, so the international community informally named it the Nixon shock http://en.wikipedia. org/wiki/Nixon_Shock

  51. 51. "The root problem with conventional currency is all the trust that's required to make it work. The central bank must be trusted not to debase the currency, but the history of fiat currencies is full of breaches of that trust. Banks must be trusted to hold our money and transfer it electronically, but they lend it out in waves of credit bubbles with barely a fraction in reserve. We have to trust them with our privacy, trust them not to let identity thieves drain our accounts." Satoshi Nakamoto, Bitcoin: A Peer-to-Peer Cash System, 2009 In Banks we Trust
  52. 52. In Bitcoin we Trust? Bitcoin isn’t tied to any commodity—besides trust. As a statement on the global economy, Bitcoin is hilarious. As a currency for the disenfranchised and distrustful, it’s as serious as can be. The whole thrust behind Bitcoin is that it removes the need for trust in currency; trust in bankers, trust in governments, trust that the two won’t collude to do you over, like they did with everybody in Cyprus. me-a-bit-of-money/
  53. 53. Who You Gonna Trust? Watergate! Corruption Ricky (...or why the political party system will depend on capital and banks) The affair began with the arrest of five men for breaking and entering into the Democratic National Committee (DNC) headquarters at the Watergate complexon June 17, 1972. The Federal Bureau of Investigation (FBI) connected cash found on the burglars to a slush fund used by the Committee for the Re-Election of the President, a fundraising group for the Nixon campaign.[1][2]
  54. 54. Marx: an ethics of liberation "MAN is born free; and everywhere he is in chains. One thinks himself the master of others, and still remains a greater slave than they. How did this change come about? I do not know. What can make it legitimate? That question I think I can answer."

  55. 55. Actually Ricky did not Like Marxism The election of Marxist candidate Salvador Allende as President of Chile in September 1970 led Nixon to order that Allende not be allowed to take office.[142]:25 Nixon pursued a vigorous campaign of covert resistance to Allende, first designed to convince the Chilean congress to confirm Jorge Alessandri as the winner of the election. When this failed, false flag operatives approached senior Chilean military officers, in "some two dozen contacts", with the message that "the U.S. desired....a coup."[142] http://en.wikipedia. org/wiki/Richard_Nixon
