Gibt es außer Geth und Mist noch andere Software, die die Javascript-Konsole anbietet? Ich möchte die Konsole verwenden, aber ich möchte nicht all diese Synchronisierungen durchführen.
Parity hat meines Wissens keine Konsole und MetaMask auch nicht. Gibt es noch andere Software?
Versuchen Sie geth --light console, verfügbar seit v1.5.2, aber unter "Experimentelle Funktionen" aufgeführt. Synchronisierung in Minuten , wenn nicht Sekunden .
Update - Die anfängliche Synchronisierung dauerte 11 Minuten. Anschließend dauerte die Synchronisierung von Blöcken im Wert von 7 Stunden 8 Sekunden.
Ich werde unten einige leichte Client-Statistiken dokumentieren.
Hier sind einige Statistiken (der aktuelle Block ist 2972534 :

Fazit:

Der erste Abruf von Ereignissen aus 1.000 Blöcken lieferte die Daten nicht in angemessener Zeit (ich habe 7 Minuten gewartet). Ich habe es angehalten gethund neu gestartet und den gleichen Befehl erneut ausgeführt. Die Blockdaten für die 1.000 Blöcke wurden bereits heruntergeladen und die Ereignisse wurden das zweite Mal in 15 Sekunden abgerufen.Das Synchronisieren von Blöcken im Wert von 7 Stunden dauerte 8 Sekunden:

Was ich jetzt mache, ist die Verwendung von TestRPC als Web3-Provider für Browser Solidity als Chrome-Erweiterung .
Sie können dann DAPP-Front-Ends entwickeln und ausführen und die Chrome-Konsole verwenden, um mit web3 zu interagieren.
Der einfachste Weg, den ich gefunden habe, wäre, eine virtuelle Serverinstanz einzurichten, nodejs zu installieren, testrpc über npm zu installieren und auch das Web3-Modul zu verwenden, wie im obigen Beitrag erwähnt.
In diesem Video wird beschrieben, wie Sie testrpc auf einer AWS EC2-Instanz einrichten und mit ihm über die nodejs-Konsole und Web3 interagieren.
http://www.decypher.tv/series/ethereum-development/video/1
Hier sind die für das Video verwendeten GitHub-Befehle und -Hinweise.
https://gist.github.com/AlwaysBCoding/9ce09281e5e097ce8ab7add2602c2fc7#file-scripts-txt
Es ist möglich, für nahezu jeden Client eine eigene JS-Konsole einzurichten.
Erwerben Sie zuerst web3.js . Entweder mit npm zum Installieren oder mit einer HTML-Datei, die die eigentliche web3.jsDatei enthält, funktioniert.
Stellen Sie dann über RPC eine Verbindung zu Ihrer Instanz her. Mit Knoten sieht das etwa so aus:
var Web3 = require('web3');
var web3 = new Web3(new Web3.providers.HttpProvider('http://localhost:8545'))
web3.isConnected() // should return true.
Wenn Sie mit node.js nicht vertraut sind, können Sie einfach eine Konsole nodein einem Terminal erhalten. Stellen Sie sicher, dass Sie dies in dem Verzeichnis tun, in dem Sie npm zur Installation von web3 verwendet haben.
Wenn Sie web3 in eine HTML-Datei eingefügt haben, können Sie alternativ nur Folgendes verwenden:
var web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"))
web3.isConnected() // also should return true.
Und dann können Sie die eigene JS-Konsole des Browsers verwenden.
Aber vielleicht kannst du auch einfach Metamask verwenden. Versuchen Sie web3.isConnected(), die eigene JS-Konsole des Browsers einzugeben, während Sie Metamask verwenden, und sehen Sie, was passiert.
Es stellt sich heraus , dass Sie Parity mit verwenden könnenparity --geth , damit es mit Mist oder funktioniert geth attach. So können Sie Paritys Warp-Sync verwenden und dann --gethdie Konsole verwenden.
Ein Beitrag oben erwähnt die decyphertv-Tutorial-Serie. http://decypher.tv/series/ethereum-development Die Serie wird mit einem Open-Source-Befehlszeilenprogramm geliefert, mit dem Sie sichere signierte Transaktionen zum Bewegen von Ether erstellen oder Verträge bereitstellen und manipulieren können. Es sendet sie dann auf Wunsch an INFURA, ohne dass ein Knoten ausgeführt werden muss.
Ich bin ein Schüler dieser Reihe und kann sie sehr empfehlen.
