  1. Peer production and Bitcoins. Lasse Grinderslev Andersen July 25th, 2014 Lasse Grinderslev Andersen Bitcoin talk

  2. Overview of this talk Discovery and development of ’computability’ In mathematics In engineering Important (early) breakthroughs Decentralization of production and the information economy Industrial production Peer production Bitcoins Technical Details Bitcoins in practice Lasse Grinderslev Andersen Bitcoin talk

  3. Discovery & Development: Math A general and vague notion of computability have been known for quite some time.. but: 1879 Freges publishes Begrriffshrift , invents predicate logic & isolates logical inferences. 1884 Freges publishes Die Grundlagen der Arithmetik , reduces aritmetik to logic. 1910 Russell & Whitehead publishes Principia Mathematica , sougth to reduce mathematics to logic Lasse Grinderslev Andersen Bitcoin talk

  4. Discovery & Development: Math A general and vague notion of computability have been known for quite some time.. but: 1920 Hilbert states his metamathematics program: ’ Formalize all of mathematics and prove it is consistent ’. 1931 G¨ odel proves its impossibility by reducing logic to arithmetic (by general recursive functions) Lasse Grinderslev Andersen Bitcoin talk

  5. Discovery & Development: Math A general and vague notion of computability have been known for quite some time.. but: 1936 Church and Turing independently showed there was no general solution to the Hilberts ’Decision Problem’ 1939 Rosser proves equivalence: Churchs λ -calculus, G¨ odel + Herbrands recursive functions and Turings abstract machine Lasse Grinderslev Andersen Bitcoin talk

  6. Discovery & Development: Math Sum up : The formal notion of computability was about finding the largest class of machine-computable functions AND it was shown that logical inferences was among them! Lasse Grinderslev Andersen Bitcoin talk

  7. Discovery & Development: Engineering First Turing complete machines: Name Year Comment Analytical Engine (UK) 1837 Babbage made the drawings, never built Zuse Z3 (DE) 1941 In principle TC, no branching! ENIAC (US) 1946 Programming by cables. Manchester Baby (UK) 1948 First stored program computer UNIVAC (US) 1951 First ’mass produced’ commerical computer Lasse Grinderslev Andersen Bitcoin talk

  13. Important breakthroughs Fundamental decentralization & generativity of computability: ..of hardware In the 1960s DEC introduces the mini-computer Small-scale, new markets Open specification, encouraging user modification/development Mainframe ⇒ mini-computer ⇒ PC ⇒ smartphone ..of software Open standards (IETF, W3C etc.) Open source ..of communications Networking ⇒ failure of Groschs law In the beginning were ’online services’: CompuServe, BBS, etc. FidoNet, primitive routing Internet, failure resistance ⇒ decentralized Internet build on the ’End-to-End’ principle (Saltzer, Reed, Clark, 1981) Lasse Grinderslev Andersen Bitcoin talk

  17. Overview of this talk Discovery and development of ’computability’ In mathematics In engineering Important (early) breakthroughs Decentralization of production and the information economy Industrial production Peer production Bitcoins Technical Details Bitcoins in practice Lasse Grinderslev Andersen Bitcoin talk

  18. Industrial production The industrial age have brought growth and prosperity, but.. Assumption: We are inherently selfish! ⇒ top-down institutions, material incentives, market-based approaches to everything Lasse Grinderslev Andersen Bitcoin talk

  19. Industrial production Centralization: Bigger is better High initial cost Aggressive marketing Lasse Grinderslev Andersen Bitcoin talk

  20. Industrial production One-to-many relationship between producers and consumers Lowest denominator Lasse Grinderslev Andersen Bitcoin talk

  21. Industrial production Increased barrier of entry in politics ⇒ need money from $BigCorp Strengthened Intellectual Property rights Lobbying/Regulatory Capture Lasse Grinderslev Andersen Bitcoin talk

  22. Industrial production Industrial/free market capitalistic production does seem to have some general bad sideeffects... Lasse Grinderslev Andersen Bitcoin talk

  23. Peer production Properties of new (commons-based) peer production Assumption: We enjoy autonomy, cooperating and find meaning & value in creating for others Lasse Grinderslev Andersen Bitcoin talk

  24. Peer production Properties of new (commons-based) peer production Decentralized: Production: Wikipedia, Amazon, Google, GNU/Linux, Apache , (FOSS), etc. etc. Resiliant non-SPF platforms: Bittorrent, Bitcoins, Tor, HTTP , the Internet Lasse Grinderslev Andersen Bitcoin talk

  26. Peer production Properties of new (commons-based) peer production Commons (Creative commons, GPL etc.) Modular (SETI@home, NASA Mars Mapping) Low barrier of entry Many-to-many communication and free information sharing (blogosphere, slashdot, youtube) Less aggressive income & Crowdsourcing/crowdfunding (kickstarter, indiegogo) Lasse Grinderslev Andersen Bitcoin talk

  27. Peer production Properties of new (commons-based) peer production Relying on a generative platform: Network & Devices Lasse Grinderslev Andersen Bitcoin talk
