Nebula mine development system mode

　　In the evolution of technology among EOS influence the underlying technology is very large.

Nebula mine system model development (Li Chan: 180-2853-2960 differentiable), APP system nebula mine development, mine nebula software development. We also see it in toward the center of the back, followed by the center of ills seems also return, including concentration risk, the arbitrary power of concentration. Several consensus on the mechanism, if the use DPOS, this is no way of things, will be the center of your back. So how to enhance efficiency, optimize performance, while avoiding the center of it? Adding randomness is more optimistic about my personal practice. Improve the efficiency of consensus must do a few nodes, a small amount will be fixed once the node is negative, it is necessary to a small amount, but also not fixed, that is, random play. Random play should be promising, we can pursue the matter.

Investment research, investment consulting field, in China there are corresponding service. Such a chain. The connection between the company and the people, the connection between the company and products. If there is a connection between the product and the place, time, season, weather, mapping knowledge by way of automatic writing reports, interactive natural language, etc., serving traditional capital market investors. There are a large number of new projects in the industrial background of the admission of background, the corresponding map can be moved to the characteristics of a flat ring of coins on money ring, a knowledge map currency circle.

　　① static mining revenue:

　　Push Star daily income of 5%

　　Per person limit: 200-50000USDT

　　The stars are divided into three levels: satellites, planets, stars,

　　Satellite - At least three teams Direct Push amounted to 20,000 USDT;

　　Planetary - at least three satellites to achieve direct push levels;

　　Star - there are at least three planets Direct Push reach grade;

　　② advantages:

　　1,80% repurchase from time to time into gold

　　2, the chain data disclosed

　　3, the new results will be given to two satellites, three planets, 4 stars

CREATE TABLE IF NOT EXISTS `image` (
  `id` int(3) NOT NULL AUTO_INCREMENT,
  `name` varchar(100) CHARACTER SET utf8 NOT NULL,
  `pic` blob NOT NULL,
  `type` varchar(50) CHARACTER SET utf8 NOT NULL,
  `date` datetime NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

Second php will save the image to a binary mysql database:

(1) connecting to the database file: conn. PHP :

<? php
$conn = mysql_connect('localhost', 'root', '');
mysql_select_db('study', $conn);
mysql_query("SET NAMES UTF-8");
?>

(2)图片上传并以二进制保存到数据库文件：upload. php

        $names = $_FILES['image']['name'];
        $arr   = explode('.', $names);
        $name  = $arr[0]; //图片名称
        $date  = date('Y-m-d H:i:s'); //上传日期
        $fp    = fopen($_FILES['image']['tmp_name'], 'rb');
        $type  = $_FILES['image']['type'];
        if (!$fp) {
            showInfo(' 读取图片失败！');
        } else {
            $image = addslashes(fread($fp, filesize($_FILES['image']['tmp_name'])));
            if ($image) {
                $q      = "insert into image (name, pic, type, date) values ('$name','$image','$type','$date')";
                $result = mysql_query($q);
                if ($result) {
                    showInfo('上传成功！');
                } else {
                    showInfo('上传失败！');
                }

            } else {
                showInfo('请选择要上传的文件！');
            }
        }

    } else {
        showInfo('请选择要上传的文件！');
    }
}

function showInfo($info)
{
    echo "<html><head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />";
    echo "<meta http-equiv='refresh' content='1;url=index. php'>";
    echo "</head>";
    echo "<body>" . $info . "……</body>";
    echo "</html>";
}
?>

$result = mysql_query($sql, $conn);
if (!$result)
    die(" 读取图片失败！");
$num = mysql_num_rows($result);
if ($num < 1)
    die("暂无图片");
$data = mysql_result($result, 0, 'pic');
$type = mysql_result($result, 0, 'type');
mysql_close($id);
Header("Content-type: $type");
echo $data;
