以太坊区块链浏览器(二)开发

一.效果

二. 合约信息

1.当前用户总数：

$scope.userCount = mxxData.residentCount.call().toString();

2.已分配Token数：

$scope.assingedQuark = mxxQuarkRule.alreadyAssignedAmount.call().toFixed(4);

3.下次分配Token块：

$scope.nextAssingedBlock = mxxQuarkRule.nextAssignQuarkBlock.call().toString() + "(块)";

4. 最近交易块

function updateTXList() {

    var currentTXnumber = web3.eth.blockNumber;

    $scope.txNumber = currentTXnumber;

    $scope.recenttransactions = [];

    for (var i=0; i < 10 && currentTXnumber - i >= 0; i++) { //显示十条交易记录
        $scope.recenttransactions.push(web3.eth.getTransactionFromBlock(currentTXnumber - i));
    }
}

5.最近交易

三. 链信息（ChainInfo）

1.最新块

$scope.blockNum = web3.eth.blockNumber;

var blockNewest = web3.eth.getBlock($scope.blockNum);

2.难度

blockNewest.difficulty;

3.totalDifficultyDividedByDifficulty

$scope.totalDifficultyDividedByDifficulty = $scope.totalDifficulty.dividedBy($scope.difficulty);

4.AltsheetsCoefficient

$scope.AltsheetsCoefficient = $scope.totalDifficultyDividedByDifficulty.dividedBy($scope.blockNum);

5.gasLimit

$scope.gasLimit = blockNewest.gasLimit;

6.格式化的time

var newDate = new Date();

newDate.setTime(blockNewest.timestamp*1000);

$scope.time = newDate.toUTCString();

7.区块链运行时间

$scope.secondsSinceBlock1 = blockNewest.timestamp - 1438226773;

$scope.daysSinceBlock1 = ($scope.secondsSinceBlock1 / 86400).toFixed(2);

8.已出块数

var blockBefore = web3.eth.getBlock($scope.blockNum - 1);

if(blockBefore!==undefined){

    $scope.blocktime = blockNewest.timestamp - blockBefore.timestamp;

}

9.最后100块评价出块时间

$scope.range1=100;

range = $scope.range1;//从当前往前数100

var blockPast = web3.eth.getBlock(Math.max($scope.blockNum - range,0));

if(blockBefore!==undefined){

    $scope.blocktimeAverage1 = ((blockNewest.timestamp - blockPast.timestamp)/range).toFixed(2);

}

10.整个链出块时间

range = $scope.blockNum;

var blockPast = web3.eth.getBlock(1);

if(blockBefore!==undefined){

    $scope.blocktimeAverageAll = ((blockNewest.timestamp - blockPast.timestamp)/range).toFixed(2);

}

11.是否连接（True）

$scope.isConnected = web3.isConnected();

12.API-Client Version：0.12.2 - Geth/v1.8.4-stable/linux-amd64/go1.10

$scope.versionApi = web3.version.api;

$scope.versionClient = web3.version.client;

($scope.versionNetwork = web3.version.network;

$scope.versionCurrency = web3.version.ethereum;)
