Blockchain Revolution | Giovanna Fessenden | TEDxBerkshires

The success of the digital currency Bitcoin is due in large part to its underlying architecture, the block chain. The block chain is distributed-ledger technology that enables payments and other transactions to be processed and stored in an entirely decentralized way—without banks or other intermediaries. The block chain’s distributed-ledger helps keep its content resistant to tampering and modification. This distributed architecture of the block chain helps eliminate the chances of having a single point of failure and makes it more robust against hacking. Giovanna will discuss what the future may hold for an internet augmented by the block chain – a block chain internet where nothing can be deleted or modified.

Giovanna has been practicing as intellectual property (IP) attorney specializing software patents for fifteen years. Giovanna dedicates a significant portion of her practice to advising businesses in technology and the creative economy. Her firm, Hamilton Brook Smith Reynolds, is an Intellectual Property boutique with offices in the Boston Seaport and Concord. In addition to expertise in intellectual property law (including patents, copyright, and trademark), Giovanna concentrated in computer science and art history in her undergraduate studies at Smith College. She has lived in Lenox, Massachusetts for nine years with her family. She spends her free time competing in triathlons as well as rowing, paddle boarding, and in the pottery studio.

  1. Get free from Central Powers/Control by using peer-to-peer
    cryptographically secure decentralized systems like Bitcoin, and make
    yourself some money at the same time, since bitcoin will continue to
    increase in value for decades to come, since it is limited supply and is
    used ever more for numerous applications, money/currency is just its first

  2. Bitcoin’s Blockchain is a *World Wide distributed Ledger* (see: [Blockchain
    technology]( No individual or
    group and no central power or government can control, kill, manipulate,
    clone, ban or confiscate it.
    Bitcoin is backed by mathematics, open source code, cryptography and the
    most powerful and secure decentralised computational network on the planet,
    orders of magnitude more powerful than google and government combined.
    There is a limit of 21 million bitcoins (divisible in smaller units).
    “Backed by Government” money is not backed by anything and is infinitely
    printed at will by Central Banks. Bitcoin is limited and decentralized.

  3. All the major banks and ‘smart money’ are investing in bitcoin and related
    startups, as well as they are buying physical gold and silver, they know
    what’s coming soon.. Also, the amount of bitcoins is limited to 21 million
    ever. Remember when bitcoin was less than 1 dollar each?. there are cycles,
    it grows to the 10ths of dollars and crashes to 1 dollar, then in “bubbles”
    to 100 and crashes to 10 dollars, next bubble went to 1000 and then crashed
    to 200’s, next bubble will go to the 10,000’s and then “crash” to $3,000

  4. I think La’Zooz idea is pretty interesting but a huge chunk of the
    marketshare has been dominated by Uber and Lyft. Nobody except the drivers
    will care about whether it is decentralized because all riders care about
    is price and comfort. Even if all drivers quit to La’Zooz, Uber and Lyft
    will soon release self-driving cars and take over this sharing economy

    • Self driving cars can be owned by cooperatives on the blockchain,easily.And
      when you cut out the middleman between the driver and rider,the driver can
      get a higher profit while competing with uber.

    • I agree, but we can’t have a complete decentralized Uber ridesharing
      service. There needs to be some common standard for setting prices even if
      it’s decided by the drivers. At the end of the day, we’re humans..not
      machines (exception of self driving cars)

    • Well,yes a common standard is necessary,to avoid that drivers are exploited
      as cheap labour.This common standard has to be connected to the status of
      the driver as a kind of taxi driver.With a minimum wage.This is a political

  5. 5:01 those dots on the map are full-nodes open to connections, not the
    miners themselves. Nobody really knows where all the miners are. Great talk

  6. Blockchain is merely the newest buzzword to scam investors with the latest
    hype cycle. Blockchain’s aren’t interesting without work, and without PoW
    institutions would be better off simply using distributed hash tables among
    databases. “Immutability” is a consequence of work , which most of these
    private blockchains and DLTs don’t want to incorporate.

  7. At the 5 min mark the map reflects full nodes and not mining nodes.
    Giovanna doesn’t seem to understand the underlying value of bitcoin or why
    “private blockchains” aren’t very interesting and provide no value over
    what we have been using in the last 20 years.
