un enlace a la guía de ayuda Básicamente, usted se acaba de convertir tu ordenador en un conmutador de red. Tenga en cuenta que aunque la gente suele hablar de "el 51% de los ataques de' no hay magia umbral del 50%. Usted podría hacer un 51% de ataque con el 49% de los hash de poder, que sólo sería un poco más difícil. @ChrisMoore: Sí, aunque no es necesario tener la cantidad exacta; no puede ser simplemente un cambio de la salida de Alicia y una salida de cambio de Bob. Supongo que si lo que usted describe con el contrato de seguro es una vulnerabilidad depende del caso de uso; por lo general el destinatario tendrá una obligación si se recibe el pago, así que él no tiene ningún incentivo para fingir. Finalmente entendí. En el paso #5 de la BIP 143 sighash creación, una secuencia de comandos se anexa, el primer byte de que es 0x19. He utilizado el .NET/C# función BinaryWriter.Escribir(0x19) para escribir ese byte. Por razones que no acabo de entender, el 0x19 byte fue tratado como un entero de 32 bits, efectivamente escrito 0 x 00000019 y ensuciar la imagen binaria. La sustitución de la línea de código con `bw.Escribir((byte)0x19)` se ha solucionado el problema y la transacción se logra. Gracias por señalarme en la dirección correcta.
  1. Si usted no está seguro de si su wallet balance es bueno, buscar su dirección en el Bloque Explorer. Si usted ve que sus monedas no, son seguros. Supongo que es esta dirección, así que todo debería estar bien.
  2. Asegúrese de que su cliente es hasta la fecha. Si es demasiado viejo podría no ser capaz de comunicarse con la red. (recuerde que la copia de seguridad de su cartera.dat de antemano)
  3. Si su cliente actualizado no se puede conectar a la red (0 conexiones), echa un vistazo a este tema.
  4. Si el cliente está conectado a los compañeros, pero después de una hora no ve ningún bloque de progreso, intente cerrar el cliente, la eliminación de blk .archivos dat de su Bitcoin directorio de datosy, a continuación, empezar de nuevo.
  5. Cuando vea a su número de bloque de progresar, ser paciente. Deje su computadora con el cliente a través de la noche. El procedimiento toma un poco de tiempo, como Bitcoin necesita para descargar y verificar más de 1 gb de datos.

Si todo lo demás falla, puede intentar canjear su cartera en MtGox (recuerdo exactamente si este es el único servicio que proporciona esta funcionalidad) y el uso de un servicio de cartera en internet, como StrongCoin, para nunca tener que lidiar con el problema de nuevo.
