The internet of money

343 |

Not the money for internet.

Communication

346 |

We want to communicate and to interchange value. 347 |
Money is an abstraction — a language — to do it. 348 | 349 |

350 |
351 |
352 |

Protocol

353 |

A protocol is essentially a language. 354 |
Bitcoin is a protocol running as application — representing value with new revolutionary unique characteristics 355 | — on a platform. 356 |

How Bitcoin works

560 |
    561 |
  • 562 | 563 | 564 | 565 | 566 | 567 | 568 |

    01. Transactions

    569 |

    Partecipants send bitcoin to each other (paying fees), cryptographically signing a tx

    570 |
    • 571 |
  • 572 |
    573 | 574 | 575 | 576 | 577 | 578 | 579 |

    02. Blocks

    580 |

    The network collects all the tx made during a set period into a list, validating them as consensus rules mandate

    581 |
    • 582 |
  • 583 |
    584 | 585 | 587 | 589 | 590 | 591 |

    03. Mining

    592 |

    Miners notarize blocks (containing txs) writing them on top of the previous blocks of the general ledger — ie., the blockchain.

    593 |
    • 594 |
  • 595 |
    596 | 597 | 598 | 600 | 601 | 602 |

    04. Reward

    603 | To notarize blocks miners have to do a very expensive activity (proof-of-work) — ie., solving difficult mathematical problems 604 | competing with other miners. Since mining is very expensive they receive a reward, the only way to create bitcoins. 605 |

    712 | The tx cannot be blocked or reversed in any way. 713 |
    No tx can be censored. 714 |
    No matter what are the parties in the game. 715 |
