por favor, cierre, traté de borrar... fue un poco en broma, pero no tan divertido en la ejecución, especialmente cuando alguien trató de ayudarme. sry, no lo hacen de nuevo, saludos! Me pregunto si #3 iba a obtener mejores respuestas en serverfault? No "algunos algoritmos de aprendizaje automático / clasificador" trabajo bajo el supuesto de que hay algo oculto patrón en los datos que simplemente no ve? ¿De dónde viene el patrón de venir de en este caso de uso, cuando los datos son algunas de las claves aleatorias y hash? @Kevin Laicos Este tipo de ataque es por qué la gente a aceptar bitcoins normalmente esperar al menos 6 confirmaciones (bloques adicionales) antes de completar una transacción. Algunos de espera para el 30. Un doble pasar finalmente será rechazado y el bloque que incluye que pasar va a ser ignorado, esencialmente tratan como si nunca hubiera sucedido. Así que si por ejemplo usted acepta 1btc para su coche usado, y te regalan el coche sin esperar a las confirmaciones entonces sí, es posible que usted va a perder su coche y su btc.

Nos gusta decir que Bitcoin está descentralizado, y lo es, pero todos los datos se pueden ver como una centralizado "fuente de verdad": el blockchain. Todas las transacciones que han ocurrido son una parte de esta fuente de la verdad. La gestión y el mantenimiento de esta fuente de la verdad, sin embargo, es descentralizada. Nadie se hace cargo de ella, sin embargo, todos están de acuerdo en un único conjunto de datos.

El rayo de la red, sin embargo, es aún más descentralizado. No sólo la gestión y actualización de sí mismo, sin autoridad central, pero no hay consenso sobre la "verdad" de la red. La actividad que se produce entre dos de los participantes en un canal es sólo el negocio de los participantes, y nadie necesita ver. Por lo tanto, no es compartida, y a menos que los participantes quieren, no se almacena. Una vez que el canal se cierra, los participantes han asentado por completo todas las transacciones entre uno y otro con una sola transacción a la principal blockchain de Bitcoin. Que muy bien puede persistir los datos de la actividad para sus propios fines, pero no es de ninguna manera necesario para continuar participando.
