"Bit gold was designed as an ideal, abstract model for a decentralized digital currency."
The quote suggests that "bit gold" was conceived as an ideal or theoretical blueprint for a digital currency that operates without central authority. This design includes the concept of decentralization, where transactions occur directly between participants, rather than through intermediaries like banks. The essence of bit gold is to create a robust, secure, and transparent digital monetary system.
"A smart contract is a set of promises, specified in digital not analog form, which transactions automatically enforce."
The quote by Nick Szabo suggests that a smart contract is an agreement or set of rules between parties, represented digitally, and executed or enforced automatically upon fulfillment of predefined conditions without human intervention. This innovative concept facilitates the creation of self-executing, tamper-proof agreements on blockchain networks, increasing trust, efficiency, and reducing the need for intermediaries in various transactions.
"Bit gold's core innovation was to combine the functionality of a digital currency and a digital commodity into one."
The quote suggests that "bit gold," an early concept for a digital currency proposed by Nick Szabo, combined two essential features: functionality as a digital currency (allowing transactions) and functionality as a digital commodity (having intrinsic value and scarcity). In essence, bit gold was designed to offer the benefits of both traditional currencies and physical commodities, making it unique in the emerging field of digital assets.
"The key property that makes bit gold function as a digital currency (and distinguishes it from a conventional database) is the ability for any participant to mint new coins by finding a proof-of-work solution."
This quote by Nick Szabo highlights the fundamental characteristic of "bit gold," an early proposed digital currency concept, that sets it apart from traditional databases. The ability for any participant to create new coins (mint) by solving a complex mathematical problem (proof-of-work) is what enables bit gold to function as a digital currency. This process, known as mining, serves two primary purposes: it validates transactions and ensures the creation of new coins follows predetermined rules, thus maintaining the integrity and scarcity of the digital currency.
"Security through obscurity is a fallacy; cryptographic security rests upon mathematics rather than secrets."
This quote emphasizes that relying on secrecy or complexity (obscurity) for protection, particularly in the field of cryptography, is not reliable. The real foundation of cryptographic security lies in mathematical principles and algorithms, not in hiding information from potential adversaries. In simpler terms, it's a warning against the use of complexity as a substitute for proper encryption techniques.
With original cryptography, you are just trying to secure one narrow thing - say, communications - and you are trying to secure it from a third party. But you can't secure it from the party you are talking to if they forward your email; it doesn't matter how well your email is encrypted.

Instead of the cashier and ticket-ripper of the movie theater, the block chain consists of thousands of computers that can process digital tickets, money, and many other fiduciary objects in digital form. Think of thousands of robots wearing green eye shades, all checking each other's accounting.

There's a strong distinction to be made between dry code smart contacts and wet code's physical law. So law is based on our minds, our wetware - it's based on analogy. The law is more flexible; software is more rigid. Various laws tend to be batched in jurisdictional silos. Software tends to be independent.
