Ya que usted está utilizando blockchain.info como su cartera de proveedores, es probablemente mejor si se les pregunta cómo están tus llaves administrado o leer sus preguntas más frecuentes Ah, me golpearon por 20 segundos o así. :) Mil gracias Murch!! Vamos a ver van a responder el tweet. Hasta ahora todavía no consigue nada. La nota, que incluye el cero de la seguridad o de las firmas. Gracias por la info; también un lado - soy un Fordham alumnos como bien :) Pensé setgenerate verdadera opción se eliminó. Gracias. Qué significa cuando la minería? Podría usted por favor, edita tu pregunta para aclarar que Permítanme añadir un comentario: de algún modo, todos los bancos tienen en sus DB un "blockchain" de sus transacciones. Pero se debe nunca ser sincronizado :) ya que es único en el mundo (por cada banco), comenzó cuando el banco comenzó su actividad y no se comparte con nadie @NateEldredge Muchas de las estructuras de datos de la serialización uso int/largo/corto/..., y serializar las personas directamente. El código de serialización de por sí hace lo correcto, pero los datos de la serialización no.

Hay un número de ataques que tienen el potencial de permitir a un atacante doble pasar, pero ninguno de ellos tiene éxito cuando la práctica recomendada de aceptar el pago sólo cuando la transacción tiene seis o más confirmaciones en contra de ella.

Por ejemplo, si un comerciante acepta el pago inmediatamente después de la 0/sin confirmar, una "raza de ataque" a veces puede ser exitoso en un doble gasto por un sencillo atacante.

Además, no es el Finney ataque que requiere un poco más de esfuerzo (sólo es posible cuando la minería y ha resuelto un bloque). http://en.bitcoin.it/wiki/Weaknesses#The_.22Finney.22_attack

Hay otro ataque que requiere un poco más de sofisticación, donde un comerciante de aceptar incluso con 1/no confirmado puede encontrar fácilmente los fondos perdidos debido a un doble pasar: http://bitcointalk.org/index.php?topic=36788.msg463391#msg463391

Hay sugerencias en cuanto a cómo la mayoría de los comerciantes todavía puede aceptar el pago inmediatamente en 0/confirmar con el mínimo riesgo para un doble pasar ocurriendo a pesar de que requieren algunos procesos adicionales que aún no se han desarrollado, probado y refinado.

Además, existen otras aproximaciones a este problema, por lo que no hay ninguna confirmación retrasos a pesar de sus implementaciones son externos y no se benefician de la arquitectura descentralizada de Bitcoin (es decir, cada uno requiere de confianza dado a otro partido):

  • Utilizar algún otro sistema de contabilidad o Transacciones Abiertas
