Attack of the 50 Foot Blockchain

Author: David Gerard
Publisher: David Gerard
Release Date: 2017-07-24
Genre: Business & Economics

An experimental new Internet-based form of money is created that anyone can generate at home; people build frightening firetrap computers full of video cards, putting out so much heat that one operator is hospitalised with heatstroke and brain damage. A young physics student starts a revolutionary new marketplace immune to State coercion; he ends up ordering hits on people because they might threaten his great experiment, and is jailed for life without parole. Fully automated contractual systems are proposed to make business and the law work better; the contracts people actually write are unregulated penny stock offerings whose fine print literally states that you are buying nothing of any value. The biggest crowdfunding in history attracts $150 million on the promise that it will embody “the steadfast iron will of unstoppable code”; upon release it is immediately hacked, and $50 million is stolen. How did we get here? David Gerard covers the origins and history of Bitcoin to the present day, the other cryptocurrencies it spawned including Ethereum, the ICO craze and the 2017 crypto bubble, and the attempts to apply blockchains and smart contracts to business. Plus a case study on blockchains in the music industry. Bitcoin and blockchains are not a technology story, but a psychology story. Remember: if it sounds too good to be true, it almost certainly is. “A sober riposte to all the upbeat forecasts about cryptocurrency” — New York Review of Books “A very convincing takedown of the whole phenomenon” — BBC News

La cadena de bloques y los smart contracts se hallan hoy en boca de todos y, en nuestra opinión, son muchos los motivos para ello por cuanto constituyen, ciertamente, una tecnología disruptiva y con un extraordinario potencial. Sin embargo, se hace necesario conocer en profundidad sus fundamentos tecnológicos, su verdadero alcance y su posible integración en el mundo jurídico, para lo que es preciso poner los pies en el suelo y aceptar de una vez por todas que, en este asunto, el Derecho y la Informática están condenados a entenderse. Los smart contracts son “código y nada más que código”, no obstante lo cual, la mayoría de ellos son creados con la finalidad de ejecutar automáticamente los acuerdos alcanzados por las partes. Para ello, se requiere una nueva categoría, el contrato legal inteligente, que existirá única y exclusivamente en el instante en que las partes acepten los términos y condiciones previamente acordados. El contrato legal inteligente se construye sobre la estructura de un smart contract subyacente, pero su alcance va mucho más allá, por lo que es imprescindible el análisis de su formación y de los elementos que imperativamente lo componen. El incumplimiento de los requisitos legales conducirá, inevitablemente, a los smart contracts ante los órganos jurisdiccionales, e irrogará perjuicios absolutamente innecesarios.
