Nine Trust-Based Problems With Bitcoin

Bitcoin seeks to be an electronic cash (currency) system that doesn’t rely on trust. Paradoxically, Bitcoin requires a trust-based ecosystem.

As a brief summary: The Bitcoin system was developed as an electronic currency by Satoshi Nakamoto (apparently, a pseudonym). Bitcoins exist only in the online world (they have no physical form). Each Bitcoin is uniquely identified, and is part of a limited edition (only a pre-set number will be issued). And, if properly executed, Bitcoin transactions are anonymous and non-reversible. For a more detailed explanation of Bitcoin’s architecture, see Benjamin Wallace (Wired) or The Economist.

Bitcoin is intended to be digital cash/currency, based on cryptography and peer-to-peer networks, rather than trust. As Nakamoto explains:

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.

Nakomoto cites as conventional currency’s root problem: “all the trust that’s required to make it work.” But Bitcoin requires us to replace trust in legal systems, institutions and procedures, with a system where we must:

  1. Trust the willingness of counterparties to accept Bitcoin as currency for payment — a huge leap of faith. Purchasing Bitcoins means participation in a 100 percent trust-based system, without any legal mechanism to compel their acceptance. Conventional currencies rely not just on trust, but also on the force of law. For example, in America the “Legal Tender Statute” (31 USC Sec. 5103) specifies that: “United States coins and currency … are legal tender for all debts, public charges, taxes, and dues.” No country issues Bitcoins, and no government legally compels anyone to accept them as payment.
  2. Trust unregulated institutions with your personal bank information just to purchase Bitcoins. As described in Mother Jones:
    • … if you … have qualms about handing over all of your bank information to an anonymous internet stranger, then you might want to just give up now. The major Bitcoin exchanges don’t accept credit cards …
  3. Trust a cryptographic, peer-to-peer network computer technology most Bitcoin users don’t understand.
  4. Trust that Bitcoin (really, a beta) won’t be replaced by a superior digital currency system, rendering original Bitcoins obsolete and worthless.
  5. Trust that the Bitcoin Foundation/other participants won’t create additional Bitcoin series, thereby diluting the value of the original Bitcoins.
  6. Trust that governments won’t intervene to render Bitcoins worthless (e.g., if Bitcoins facilitate too much drug-dealing or money laundering, the U.S. government could make their possession illegal).
  7. Trust an anonymous creator (Nakamoto) who’s mysteriously “moved on to other projects” and disappeared.
  8. Trust that Bitcoin markets will be available to provide prices in real currencies — as recent events demonstrate, also a leap of faith.
  9. Trust that your Bitcoins are stored in a secure location. Precisely because Bitcoin transactions are anonymous and non-reversible, they’re highly vulnerable to theft. If your Bitcoins are stolen, they’re pretty much untraceable. For a non-exhaustive list of major Bitcoin theft incidents, click here.

Rather than as currency, perhaps we should evaluate Bitcoin as the first example of Dadaist Digital art. An art work exists as part of some limited edition and has no intrinsic use. If you purchase art (for financial reasons), you must believe/trust that members of the art ecosystem will value/be willing to purchase that work at a future time.

Dadaism was:

an … international movement … repudiating and mocking artistic and social conventions and emphasizing the illogical and absurd.

One of Dadaism’s first major works was Duchamp’s Fountain (created under the pseudonym R. Mutt). As shown below, Fountain is an off-the-shelf, mass-produced urinal.

The urinal designated as Fountain, however, had considerable value. Replicas, authorized by Duchamp, have sold for over $1 million each.

Duchamp made an important artistic statement with Fountain; but on another level, he created an intellectual joke about the nature of art.

Nakamoto, in “Bitcoin: A Peer-to-Peer Electronic Cash System” and other writings, makes important observations about cryptography, currency and the nature of trust.

Bitcoin’s design is highly significant and will likely influence payment systems for years to come. However, Bitcoin’s implementation feels like an elaborate intellectual joke. Under the guise of eliminating the need for trust, Nakamoto demonstrates that trust is an inescapable part of payment systems.

Is Satoshi Nakamoto the Duchamp of our Digital generation? Bitcoin’s inventor seems sophisticated enough to understand that, as currency, Bitcoin’s long term value might be zero. But analogous to Duchamp’s Fountain, Bitcoin might be intellectually priceless — for the issues it highlights (or as the first example of Dadaistic Digital Art).

    I wonder sometimes where Money gets its strange sex-appeal. Apart from attraction to the other gender, there is probably nothing else that stirs such intense feelings. Some people love Money, others hate it and dream of a world without it, but no one is indifferent to it. I am always rather amazed whenever I enter a shop offering a Product, whether goods or services, the shop will readily accept a bit of paper with a rather dull picture on it in exchange for any Product I choose to purchase.
    It never fails: when I enter a shop, the same scenario always works. And it works in spite of the fact that there is no real value behind the Money I am handing over. If the shopkeeper bothered to inquire at all, he would soon find out that this money is not really backed by gold, diamonds or any other "valuable thing". He would realize that the only reason the Money has any value is because it is just his experience that whenever he enters the shop next door to purchase a shirt, or whatever he needs, he can pay for it with the same paper Money he received for the Product he sold.
    How come this all works? The answer is faith, and if you think of yourself as a rational atheist who believes in nothing unless he has real evidence for its existence, then you shouldn’t be giving or accepting Money. Money is all about faith in Money, trust that it represents a certain value exchangeable for Product, regardless of whether the pictures on the bank notes are funny, inspiring or just anachronistic, or whether like dollars they carry the legend, "IN GOD WE TRUST". To be honest, I would probably have "IN PAPER WE TRUST" printed on dollar bills.

    None of the issues you mention is actually a problem with the Bitcoin network or its protocol. Even Dan Kaminsky has stated that he can't hack Bitcoin. If Bitcoin is still up and running, we can assume no one else has hacked it either.

    Bitcoin mocks the central banks by its very existence. The fact that Bitcoin can't be taken will only further the decaying reputation of banks, which have now entered their own Dada period.

    "Under the guise of eliminating the need for trust, Nakamoto demonstrates that trust is an inescapable part of payment systems."

    In the world of human interaction and exchange, trust is and always will be a component of any transaction. In the larger economic world, I choose to place my trust in the laws of physics, math, cryptography and my peers on the network over trusting to the whims of central bankers and their hangers-on in governments and corporations.

    Excellent analysis. Thank you.

    If you have a digital file which denotes a certain unit of money, what's to stop you copying it then sending that copy to two people as payment? Usually it would be a third party keeping track of everything.

    Bitcoin eliminates trust in such intermediary by making the system operate more like cash does. That's why it's called digital cash. This is the type of trust bitcoin is eliminating, Satoshi isn't referring to any of the types you list.
