I applied your airdrop when I was newbie in bitcontalk month ago, I signed the signature camp but didn’t receive Semux token, I heard there are the rule change that in Oder to qualify for airdrop need to be Member level,  after couple week I didn’t receive any token, I remove my signature.
If I reach member, Can I reapply for signature camp?

A private key is always mathematically related to the wallet address,
but is impossible to reverse engineer thanks to a strong encryption code base.

Never share or post your private key to anywhere.
In Oder to receive your fund, you only need to share your address with others.

其实我建议楼主,如果有这个技术或者想法,你可以写一写关于搭建海外节点方面的教程,现在流行节点挖矿,需要租用阿里云等公司的服务器,但是很多节点是用linux系统来安装软件的,老外的教程难以看懂,大家对这个可能更感兴趣吧。
毕竟区块程序编写这个离我们大多数人太过遥远了。

我只懂很基础的编程,这个根本就是编程基础入门,教别人我还没到那个级别,
这里肯定有很多懂得挖矿技术的牛人

There are a lot of good news sources for cryptocurrency depending on what is exactly needed, You can use CoinMarketCap if you want to track rates of cryptocurrencies. BitcoinTalk and Reddit are best sources for news and related to cryptocurrecnies. I'd like to suggest join the telegram channel Crypto news also the best sources of crypto currency news.

457  Local / 中文 (Chinese) / 简单区块程序编写步骤 on: February 13, 2018, 02:37:55 PM
区块连是由一个个区块组成,那么在编写区块连之前要先把区块逻辑,下面是区块编辑的简单Java 程序,原程序来自英文原编 Lauri Hartikka
对编程感兴趣的可以参考下

第一个逻辑步骤是决定块结构。
这个块中必须能找到前一个块的哈希值(hash),以此来保证整条链的完整性。




class Block {
    constructor(index, previousHash, timestamp, data, hash) {
        this.index = index;
        this.previousHash = previousHash.toString();
//这一步很重要,起到区块链接功能
        this.timestamp = timestamp;
//输入的时间
        this.data = data;
//用户提供的资料
        this.hash = hash.toString();
    }
}


块哈希
var calculateHash = (index, previousHash, timestamp, data) => {
    return CryptoJS.SHA256(index + previousHash + timestamp + data).toString();
};

为了保存完整的数据,必须哈希区块。SHA-256会对块的内容进行加密,
记录这个值应该和“挖矿”毫无关系,因为这里不需要解决工作量证明的问题。

块的生成

var generateNextBlock = (blockData) => {
    var previousBlock = getLatestBlock();
    var nextIndex = previousBlock.index + 1;
    var nextTimestamp = new Date().getTime() / 1000;
    var nextHash = calculateHash(nextIndex, previousBlock.hash, nextTimestamp, blockData);
    return new Block(nextIndex, previousBlock.hash, nextTimestamp, blockData, nextHash);
};

要生成一个块,必须知道前一个块的哈希值,然后创造其余所需的内容(= index, hash, data and timestamp)。
块的data部分是由用户所提供,这样一个签单的块就编写完了。

458  Other / Beginners & Help / Re: Can someone give me a brief about how ICO's work ? on: February 12, 2018, 03:18:06 PM
ICO typically involves selling a new digital cryptocurrency or a token to raise funds for a project by the company or a group of people pursuing that project.

ICO typically is has the following inclusions for explaining the concept to the investors:

1  A website containing all the information about the project like project purpose, founders and their background, token structure in various fund raising
    stages of ICO like the PRE-ICO stage and ICO stage, Discounts offered to early investors
2  A video explaining the concept and how it will bring benefits to the community accessing this platform or any disruption in a industry by using blockchain
    or Artificial intelligence or any other latest technology
3  A whitepaper explaining the business model in detail
  
Once the concept is designed and is ready for investors to view, this is then marketed on a digital marketing platforms

It’s terrible to hear about your loss and I express my sincere sympathy to you and your family

Try to identify where the bitcoins were held.
1 Look for wallet software on their computer. Once you find the wallets or know what online wallets/exchanges were used, you'll need to know their password to access the funds and transact them.
2 Look for a piece of paper or a digital file that contains a list of 12 or 24 words. Don't share those words with anyone. It's called a mnemonic seed and you can use it to import the deceased's Bitcoins onto a new wallet of your choosing. Also note that bitcoin may be held in physical form as a "paper wallet" containing public/private keys (long strings of text/numbers). They would have kept this in a safe place.
3 check email for emails from online bitcoin exchanges or wallet services that will provide clues as to their activities.
4 check browser history and bookmarks for bitstamp, coinbase, and other exchanges or other bitcoin related sites.

Have someone you can trust who is knowledgeable about bitcoin help search the computer and email. Perhaps you will find a spreadsheet or other log where they tracked their bitcoin finances that will help spell it out as well.
