A Golang client library to communicate with Ethereum RPC server.

• Implements most of JSON-RPC methods and several client-specific methods.
• Provides a high-level interface to propose/get validators on Istanbul blockchain.
• Provides a high-level interface to create private contracts on Quorum blockchain.

package main

import (
	"context"
	"fmt"

	"github.com/getamis/eth-client/client"
)

func main() {
	url := "http://127.0.0.1:8545"
	client, err := client.Dial(url)
	if err != nil {
		fmt.Println("Failed to dial, url: ", url, ", err: ", err)
		return
	}

	err = client.StartMining(context.Background())
	if err != nil {
		fmt.Println("Failed to start mining, err: ", err)
		return
	}
	fmt.Println("start mining")
}

To use these methods, make sure that

• Server is running on Istanbul consensus.
• Connect to server through istanbul.Dial function (not the original Geth client).

Methods:

• istanbul_getValidators
• istanbul_propose

To use these methods, make sure that

• Server is running on Quorum blockchain
• Connect to server through quorum.Dial function (not the original Geth client).

Methods:

• quorum_privateContract
• quorum_contract
