    Nxt神话系列之5: 不安全的密码

    作者：salsacz
    原文：http://nxtcoin.blogspot.com/2014/01/nxtmyths-5-unsafe-password.html
    译者：NxtChoice  http://c.blog.sina.com.cn/profile.php?blogid=eda31cb189000v9z

    因为所有的Nxt账号都存储在网络中，难道没有可能被有些人猜中我的秘钥而很容易地获取我的币吗？

    这是一个十分重要的问题。查看我们的账户安全页面可以得到详细深度的答案。简而言之，本问题着重强调在创建Nxt账户时要使用安全性高非常强的密钥。

    如果在Nxt客户端中设置的密钥少于30个字符，那么就会出现账户存在安全风险的提示。而具有很好随机性的50到60个字符的字符串密钥将大大降低账户被暴力破解的风险或者碰巧被其他用户使用相同的密钥。

    Nxt支持10^77个不同的账户（即100 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000个账户），因此可能的密码范围非常庞大。你可以使用网站https://howsecureismypassword.net/ 来测试密钥的可靠程度，并评估一般的电脑用来破解改密钥所需要的时间。

    为了安全起见，可以使用一个30个字符长的密钥，就如下面类似的形式：a6f-5g46§s5g16s5dg16s5df1g6s,51gů§6a54ůfv6\,96d76E5D4.

    脑钱包

    Come-from-Beyond：
    “哎，我们将遵循比特币 5年前的方式，我仍然相信脑钱包比硬盘上的文件钱包安全得多。”

    脑钱包是指通过自己的大脑记住一个密钥从而将比特币存储在自己大脑中。只要密钥没有记录在其他的地方，就可以认为Nxt仅仅存在于拥有者的大脑中。如果忘记了脑钱包，或者是拥有者死亡，或者是永远找不到，那么Nxt将永远丢失。

    脑钱包可以用一个特别的短语来创建。而且这个密钥必须足够长以防止被暴力破解，因为太短太简单的密码很容易被破解。来自于出版物上的标准短语容易被黑客快速的使用电脑来进行组合将之破解。这里建议使用一个容易记的短语，然后稍微改一改，这样比较难猜测到。

    密钥通过哈希运算或者公钥衍生算法变成256位的私钥（例如SHA256算法）。然后通过该私钥计算得到Nxt地址，或者说一个确定的地址序列。

    Nxt可以被发送到这个地址。为了得到Nxt，必须使用相同的密钥重新计算得到私钥。私钥可以被导入到钱包中。当创建一个脑钱包的时候，使用一个熵值很高的秘钥是极为必要的，否则脑钱包将被盗无疑。

    这并不是一个简单的建议，而是必须的步骤。当大多数的人被问及设置账户密钥的时候，他们使用已知的全部方法来创建一个脑钱包的密钥，但最终仍然会出现钱包被盗。很简单的事实就是，黑客破解脑钱包密码的时候，仅仅是在做数学计算，既不需要上网， 也不需要通讯，也不会留下任何痕迹，并且黑客们在家里就可以每秒测试上万亿个密钥。

    由包括大写，小写， 数字以及符号在内的10个字符组成的银行账号的密码已经是一个非常强的密码了，但是这样的密码不足以保护脑钱包的安全。

    传统的银行账户或者社交网站的安全密码不能简单地适用于脑钱包。

    脑钱包的密钥至少需要从未出现在任何歌曲或者文学作品中的一整句完整的话。如果能够键入一些易记的个人信息，那么安全性将会大大提高，个人信息不需要非常秘密（例如一个email地址，或者是电话号码）。一个好的脑钱包密钥必须有成打的字符。

    EvilDave, you can't pretend any longer. You're a saint.

    I love the idea, especially sustaining it through forging. This could also be a very easy way for people who want to give back some of what they've gained to donate to some very good causes. A minimum balance and a time interval could be defined, and periodically all Nxt in the account that exceeds the minimum balance can be spent on these worthy causes.

    I think one of the genuine aims of cryptocurrency is to make the world a better place, and this just fits very well.

    On a less altruistic note, this would also generate some very good PR for Nxt.

    Finally more people shows up who genuinely want to make a change with NXT. Don't get me wrong: I want to be rich too, but I didn't get into cryptocurrencies for that, my main interest is in makin a change

    In this 2nd video with Anon136, we will discuss how the Nextcoin (NXT) network defends against a 51% attack which some consider to be a weakness in the Bitcoin protocol.

    We will discuss the possibility of such an attack on the Nextcoin (NXT) protocol in theory and if it really is possible in reality.

    I just heard back from my designer friend and they are getting really excited.

    Basically they are a company whose core business is delivering total brands, so they could "pull together" the Nxt image.
    We could have one style worked through apparel, business cards, promo materials etc.

    I've sent them the current material and stressed that the logo is a given, but invited them to play around with it and show us what they come up with.

    Just so you know who they are, here is the company website: http://onepagedesign.nl/

    The portfolios for the two people who will be working on it:

    1. My mate:
    http://dutchgamedesign.wordpress.com/portfolio/ (fairly old)
    http://www.redbubble.com/people/bergmandesign/portfolio

    2. The "other" guy, whom I haven't met yet.
    http://www.idxsign.com/

    Currently they are working for Samsung and Vodafone on a project.

    We are setting up a meeting to see what they could do, but it's sure they could provide us with all branding designs if we want.
    They would be willing to do this for 30.000 Nxt, as they believe that if they do a good job, and Nxt rises in value it will be a very good investment.

    Well, their work is ok...

    I have posted in the main thread a proposal for the Process to deal with the unclaimed coins. Please give feedback on the main thread

    **************
    Proposal for Unclaimed NXT

    I suggest we put up a slate of 7 trusted members that the thread discussing this will recommend. Then we put it up for an up or down vote.

    If approved, the unclaimed NXT are divided among the trusted 7. They will be obligated to disburse funds that are approved by a marketing committee (3 Million NXT) and a tech committee (5 Million NXT) and an infrastructure committee (1 Million Nxt).

    The election to the marketing, tech and infrastructure committees are independent from the decentralization of the unclaimed NXT. This means we can independently figure out who is on the three different committees and as soon as one group is formed, projects can be funded.

    The community has already decided on 250,000 NXT per month for Marketing, so the marketing committee task is to figure out how best to allocate that budget.

    tech and infrastructure committees have not formed yet, but we don't need to figure out all the details for getting the trusted 7 members in place.

    Pouncer's Proposal

    This is my simplified suggestion.

    Select 3 founders to be treasurers for the unclaimed funds.
    One to hold marketing, tech & infra respectively.
    Treasurers will not sit in any committee

    Make this selection simple & fast by putting up 3 names and waiting for no objection (1-2 days) period. Any objections should be followed by a good reason. I suggest jl777 propose the 3 names.

    Once this is settled, we can do the nomination/election process for the 3 committees.

    What this will solve:
    1. Unlikely for founders to "run away" with the trusted funds.
    2. They will be in for the long haul
    3. They voluntarily give up their right to decide on the usage of funds. Founders will not be seen as monopolising the decision making process, thereby pleasing the opponents of 1NXT = 1Vote to a certain extend.
    4. Gives more opportunities to other stakeholders to participate in building up Nxt.

    **********
    This is much better than my proposal.

    It is time to formalize who is on the marketing committee and how large it is. This committee will decide on how the 3 million NXT will be spent in 2014

    Once a decision is made, the treasurer will disburse the funds. The treasurer cannot be on any funding committee.

    This is a big breakthrough in funding logistics. I suggest for a rule that the marketing committee consider payments of salary normalized to fiat for people like salsacz who are working fulltime and making results. To avoid conflict of interest, any voting on salary issues should not count the votes of anybody that is being considered for salary position

    This is common sense, I hope you agree

    Both me and salsacz work fulltime on NXT, yet I think both of us want to be paid in NXT rather than fiat if it comes to that.
    We work on NXT because we truly believe in NXT so obviously more NXT = more dedication.
    Of course you have to be able to live on the side Smiley But if one runs into real life economic issues you just have to sell some NXT, but at least then the person decides himself how much of his salary is being invested and how much is being spent on food ^^

    By normalize to fiat, I mean calculate a reasonable salary in fiat and then get paid in that amount of NXT. For example, if NXT goes up tenfold, we are all happy, but if you are getting a reasonable salary amount before it goes up tenfold, then I imagine a lot if people will feel you are getting unreasonable amounts if it was 10 times more.

    Of course if NXT is 10 times more, we are all happy, but I have to be concerned about such matters.

    Sure I understand your position, but at the same time: if it goes up 10 times partially due to that work... then I think the salary should go up.
    There are just so many variables here.

    Registration for the Toronto, Canada Bitcoin conference in April (Bitcoin Expo 2014) is now open:

    http://www.bitcoinexpo.ca/registration.php

    Prices in CDN$:
    - The dates are April 11-13, and prices range up to $400 for the VIP package. 
    - Airfare from where *I* am to Toronto comes to about $650

    I am going to reach out to the organizers later today to find out about speaking possibilities exhibition possibilities.  The theme of the conference may make a speaking opportunity for Nxt a little tricky, but I'm sure we can get expo space if we look into it.  I'll let you know more as soon as I can.
    maybe you could try to go very deep in the Nxt decentralized system - to show its opportunities

    I've just gotten a friendly webdeveloper interested in creating Nxt payment modules for Wordpress, prestashop and magento (possibly other open source e-commerce systems, too).

    He's currently swamped with work, but is going to read up this week and I expect a reaction during next week.
    good. I would also vote for Shopify and Drupal, maybe also donating button for Blogger Smiley

    It's mobile compatibale. I will work on the blog very soon.

    First I will translate the test to other languages.

    If I could get donations, I could also host this website with a better domain name and it would be faster.

    I can see you changed the site, but it is little outdated. Or did you move to somewhere else?
