¿Hay algún software aparte de Geth and Mist que ofrezca la consola Javascript? Quiero usar la consola pero no quiero hacer toda esa sincronización.
Parity no tiene una consola que yo sepa y MetaMask tampoco. ¿Algún otro software por ahí?
Pruebe geth --light console, disponible desde la versión 1.5.2, pero incluida en "Características experimentales". Sincroniza en minutos si no segundos .
Actualización : la sincronización inicial tardó 11 minutos. Posteriormente, la sincronización de 7 horas de bloques tomó 8 segundos.
A continuación, documentaré algunas estadísticas de clientes ligeros.
Aquí hay algunas estadísticas (el bloque actual es 2972534 :

Conclusión:
geth --lightparece un poco inestable actualmente para la recuperación de eventos de una parte histórica de la cadena de bloques. La primera recuperación de eventos de 1000 bloques no devolvió los datos en un tiempo razonable (esperé 7 minutos). Lo detuve gethy lo reinicié y ejecuté el mismo comando nuevamente. Los datos de bloque para los 1000 bloques ya se descargaron y los eventos se recuperaron por segunda vez en 15 segundos.La sincronización de 7 horas de bloques tomó 8 segundos:

Lo que estoy haciendo ahora es usar TestRPC como proveedor de Web3 para Browser Solidity como una extensión de Chrome .
Luego puede desarrollar y ejecutar front-ends DAPP y usar la consola de Chrome para interactuar con web3.
La forma más fácil que encontré sería configurar una instancia de servidor virtual, instalar nodejs, instalar testrpc a través de npm y también usar el módulo Web3 como se menciona en la publicación anterior.
Este video explica cómo configurar testrpc en una instancia de AWS EC2 y cómo interactuar con él usando la consola de nodejs y Web3.
http://www.decypher.tv/series/ethereum-development/video/1
Estos son los comandos y notas de GitHub utilizados para el video.
https://gist.github.com/AlwaysBCoding/9ce09281e5e097ce8ab7add2602c2fc7#file-scripts-txt
Es posible configurar su propia consola JS para casi cualquier cliente.
Primero, adquiera web3.js. Ya sea usando npm para instalarlo, o usando un archivo HTML que incluya el web3.jsarchivo real funcionará.
Luego, conéctese a su instancia a través de RPC. Con el nodo, se verá así:
var Web3 = require('web3');
var web3 = new Web3(new Web3.providers.HttpProvider('http://localhost:8545'))
web3.isConnected() // should return true.
Si no está familiarizado con node.js, puede obtener una consola simplemente nodeen una terminal. Asegúrese de hacerlo en el directorio donde utilizó npm para instalar web3.
Alternativamente, si incluyó web3 en un archivo HTML, puede usar solo esto:
var web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"))
web3.isConnected() // also should return true.
Y luego puede usar la propia consola JS del navegador.
Sin embargo, es posible que solo puedas usar Metamask. Intente escribir web3.isConnected()en la propia consola JS del navegador mientras usa Metamask y vea qué sucede.
Resulta que puedes usar Parity con parity --gethpara que funcione con Mist o geth attach. Entonces puede usar la sincronización warp de Parity y luego --gethusar la consola.
Una publicación anterior menciona la serie de tutoriales decyphertv. http://decypher.tv/series/ethereum-development La serie viene con una utilidad de línea de comandos de código abierto que le permite crear transacciones firmadas seguras para mover ether o implementar y manipular contratos. Luego los envía a INFURA si lo desea todo sin necesidad de ejecutar un nodo.
Soy estudiante de esta serie y la recomiendo ampliamente.
