¿Has encontrado el algoritmo de firma? Traté de doubleSha(msg.getBytes) (en Java). Verificación de falla. Fui a la Bitcoin código fuente de referencia. Ver main.cpp: mapOrphanTransactions. Las transacciones se agregan por AddOrphanTx(). No hay límite en el número de huérfanos transacciones que pueden ser insertados en mapOrphanTransactions. La pregunta es por lo tanto: es un ataque DoS es posible? El Inicio y Fin de las cifras, es que satoshis o bitcoins? Gracias por su trabajo duro! Es ¿significa que tengo que configurar mi propio bitcoin servidor rpc, realmente? después de leer la guía todavía me sale un error al intentar firmar el rawtransaction. El decodificado rawtransacion ve bien, pero mientras trato de firmar me sale "Falta", incluso si en el decodificado raw transacción la cantidad correcta se muestra. Para mi enfoque, utilizo la folling parámetro: `signrawtransaction([hex_from_createrawtransaction], [inputs_used_for_createrawtransaction(txid, vsal, scriptPubKey, redeemScript)],[one_privateKey])`. Nada malo o no?

En primer lugar, no, yo no lo consideraría StackExchange a ser una blockchain. StackExchange es una centralizado sitio web, al igual que la mayoría (posiblemente todos) los sitios web.

Muchas de las propuestas que la gente hace por el uso de blockchains hoy en día realmente no requieren una blockchain para trabajar. Así, mientras que, sí, se podría utilizar una blockchain para crear un StackExchange-como el sistema de votación...usted probablemente no desea.

A la hora de decidir si una blockchain es la solución correcta, pregúntese "¿puede este proyecto de trabajo si tengo que confiar en una autoridad centralizada?". Si la respuesta es "sí", entonces usted probablemente no desea utilizar una blockchain. Una blockchain es la solución para el problema de la necesidad de un almacén de datos en la que puede confiar, sin embargo, no ser capaz de confiar en un solo individuo o a una organización para ejecutar ese almacén de datos.

En el caso de StackExchange, los mantenedores del sitio tienen un interés personal en lo que es útil, informativo y colaborativo. Si no, nadie lo va a usar, y que no hará ningún dinero de la publicidad. Por lo tanto, podemos confiar en ellos para hacer un buen trabajo de mantener el sitio. Esto es probablemente cierto para una empresa mantener un sistema de reputación para sus empleados.

En el caso de Bitcoin, no podemos tener una autoridad central que tenemos toda confianza. En el pasado, centralizado monedas alternativas fueron clausurados por los gobiernos, por lo que incluso si confiamos en una organización, tiene una debilidad. Además, ¿cuánto más podemos confiar en un sistema centralizado de advenedizo de la moneda de lo que podemos gobierno monedas? Bitcoin necesita una blockchain a trabajar, porque centralizado de confianza no funciona para el proyecto.
