This article was written before the launch of oursecond-generation hardware wallets, which we are striving to make as open source as possible for the mass market. Our first-generation Cobo Vault Ultimate had a more specialized design targeted at institutional investors, who have an interest in using closed source hardware under service agreements with liability insurance. For our first generation, we believed the risks of opening the door to hackers outweighed the potential benefits of attracting developers to contribute to making our product more robust.
本文是在第二代硬件钱包发布之前撰写的他们对根据责任保险与服务协议使用封闭源硬件感兴趣。 对于我们的第一代人来说我们相信向黑客敞开大门的风险远胜于吸引开发人员为使我们的产品更强大做出贡献的潜在好处。
As passionate advocates of open source software, we have deep respect for pioneering developers who made their work available to the world, and it goes without saying that we in the cryptocurrency field owe much to the originators of blockchain technology. It is because Satoshi Nakamoto and other great trailblazers made their work open source that we are all able to share in the benefits brought by amazing innovations such as Linux, Bitcoin, and the booming cryptocurrency market.
作为开源软件的热情拥护者不用说我们所有人都能分享Linux比特币和蓬勃发展的加密货币市场等惊人创新所带来的收益。
However, when it comes to the question of whether making source code available is beneficial for the security of hardware wallets, we enter into a wholly new discussion. This article explains our reasons why we believe the nature of open source does not represent an upgrade for hardware wallets, but rather a significant security compromise.
但是我们进入了一个全新的讨论。 本文解释了我们为什么认为开放源代码的本质并不代表硬件钱包的升级而是重大的安全性折衷的原因。
In traditional fields of computing, supporters of open source have consistently emphasized one point — open source is safer because it enables the public to inspect source code and contribute to security by helping fix potential loopholes. Linus’s law is clearly illustrated by the statistic that a zero-day attack on Safari, a closed source, takes an average 9 days to fix, while a zero-day attack on Firefox, an open source, on average only takes a single day to fix.
在传统的计算领域中因为它使公众能够检查源代码并通过帮助修复潜在漏洞来为安全做出贡献。 统计数据清楚地说明了Linus的定律(“给了足够多的眼球对Safari的零日攻击(封闭源)平均需要9天的修复时间一个开放源代码平均只需要一天的时间就可以解决。
However, Linus’s law must be understood in context, namely that of traditional computing fields. When discussing the advantages of open source software in terms of hardware wallets, we must be mindful of the fact that the traditional computing development community is immense compared to that of hardware wallets.
但是即传统计算领域的定律。 在讨论开源软件在硬件钱包方面的优势时即与硬件钱包相比传统的计算开发社区规模巨大。
GitHub, the world’s largest host of source code, indicates that there are only around 180 contributors to the open source code of the oldest hardware wallet brand, Trezor. This statistic stands in sharp contrast with the communities of other hardware products such as the Raspberry Pi, whose contributors to its open source firmware number around 9,500.
GitHub是全球最大的源代码托管者Raspberry Pi为其开源固件数量大约为9,500做出了贡献。
No project, no matter how big, is entirely immune to the potential dangers of exposing its code. Take for example Linux Mint, which washacked in 2016. Although that backdoor issue was fixed within a day, the rapid response time was in no small part due to the size of the Linux open source community.
无论项目多大它在2016年被黑客入侵。 尽管该后门问题在一天内得到解决快速响应时间在很大程度上不容小small。
In the context of our relatively small development community, we need to be especially wary of the fact that sharing source code is a double-edged sword. For hardware wallets, the unfortunate truth is that releasing source code makes it easier for hackers to detect loopholes and carry out attacks. Open source code can even open the door for cybercriminals to produce counterfeit hardware wallets capable of deceiving consumers — a security threat Trezor has alreadybeen the victim of.
在我们的开发社区相对较小的情况下不幸的事实是以生产能够欺骗消费者的假冒硬件钱包-Trezor已经成为安全威胁。
An aspect of security hardware wallet owners need to be keenly aware of iszero-day attacks. In zero-day attacks, the period of time between when a previously unknown vulnerability is exposed or announced and when it is fixed presents a perfect window of opportunity for a hacker to carry out an attack. Because vulnerabilities in hardware wallets are often resolved through firmware upgrades, it usually takes a while after official security patches have been released for users to actually install them and fix the issue. With some users who, after having set up their hardware wallet, don’t open it for months or even years, exposure to zero-day attacks is dramatically increased. Perhaps counterintuitively for those experienced with open source software development, a black box, or device with a closed source code, is more secure than a white box with an open source code.
安全硬件钱包所有者需要敏锐地意识到零日攻击。 在零日攻击中因此通常需要一段时间才能发布正式的安全补丁遭受零日攻击的风险急剧增加。 对于具有开放源代码软件开发经验的人来说黑匣子或具有封闭源代码的设备比具有开放源代码的白箱更安全。
While it is tempting to fall back on our knowledge and appreciation of Bitcoin as a prime example of the security offered by open source code, to assume that all blockchain projects should follow suit and become open source is a logical leap. The security Bitcoin enjoys from its open source development community is a direct result of the scale of its community involvement. Whether it is source code or mining functions, the Bitcoin community has gotten involved in maintaining and protecting the project, with larger numbers of involvement correlating to more secure functionality. However, because there are comparatively so few developers currently involved in hardware wallet security, we can make no assumptions about the benefits of sharing source code carrying over to this space.
虽然倾向于依靠我们对比特币的了解和欣赏作为开放源代码提供的安全性的主要示例比特币社区都已参与维护和保护项目由于目前涉及硬件钱包安全性的开发人员相对较少因此我们无法假设共享源代码到此空间的好处。
Apart from vastly increasing the number of reviewers inspecting code, another benefit of open source development in traditional computing fields is enabling anyone to download, install, burn, debug, or even remove certain aspects of the source code themselves.
除了大量增加检查代码的审阅者之外任何人都可以自己下载刻录调试甚至删除源代码的某些方面。
The security that comes with this level of autonomy is reliant on a foundation of specific technologies. However, even with a solid technological base, there is always the potential for security measures to be outdone. Those in computing fields will be familiar with how theKen Thompson Hack (KTH)created a backdoor in the C compiler than can conceivably monitor or place controls on any software program in the world. You would have to write your own compiler using binary code or use tools compiled before KTH was installed in order to overcome this security compromise. KTH demonstrates that any system compiled from a source code is always going to be vulnerable to attack.
这种自治级别带来的安全性取决于特定技术的基础。 但是安全措施也总是有可能被淘汰。 计算领域的技术人员会熟悉Ken Thompson Hack(KTH)如何在C编译器中创建后门或者使用在安装KTH之前已编译的工具从源代码编译的任何系统始终容易受到攻击。
What OGs like Ken Thompson teach us is that unless you are able to write your own compiler , you’re going to have to put your trust in a third-party. In-depth issues such as having to write your own compiler aside, the majority of hardware wallet users won’t even get their feet wet burning or debugging source code. For this cohort of users, knowing their hardware wallet is open source is more of a psychological comfort than a condition that actually amounts to a measurable improvement in their wallet’s security.
In traditional fields of computing, it helps to think of the security brought by open source software as enabling a kind of “audit” on the source code. While the same is not yet true of cold storage cryptocurrency security, what can instead be substituted as a reliable source of “audit” for hardware wallets?
在传统的计算领域但是可以替代什么作为硬件钱包“可靠”的可靠来源
Fortunately, signed transaction outputs are not nearly as complicated as the outputs of other types of software. If making source code available is not the most secure option of providing ways to audit hardware wallets, we can instead consider scrutinizing their transaction signing outputs.
幸运的是我们可以考虑仔细检查其交易签名输出。
People purchase hardware wallets because they know the most secure way to store their private keys is to take them offline into cold storage. All hardware wallet services need a means of communicating between offline storage and online terminals. While the cold end is responsible for storing private keys and signing transactions, a hot end is needed to obtain data from the blockchain, construct transactions for the cold storage end to sign, and broadcast signed transactions to the blockchain.
人们购买硬件钱包是因为他们知道存储私钥最安全的方法是将其离线放入冷存储器。 所有硬件钱包服务都需要一种在离线存储和在线终端之间进行通信的方式。 冷端(离线存储)负责存储私钥和签署交易构造用于冷存储端进行签名的交易并将签名的交易广播到区块链
In transmitting signature outputs, the majority of cold storage hardware uses data cables, Bluetooth, or even NFC. Because of the opacity of their data transmission, these methods make signature outputs extremely difficult to audit. An overlooked means of cold storage hardware communication is the QR code, a “what you see is what you get” solution. We believe the QR code is the ideal means of data transmission between cold ends and hot ends because data output by QR codes is transparent. This enables users to easily ensure each unsigned transaction that is transmitted to the cold storage device is valid, as well as ensure signature outputs from the cold end do not reveal private keys or sensitive information in any way.
在传输签名输出时蓝牙甚至NFC。 由于其数据传输的不透明性这是一种“所见即所得”的解决方案。 我们认为QR码是在冷端和热端之间进行数据传输的理想方式并确保来自冷端的签名输出不会以任何方式泄露私钥或敏感信息。
Our article onCobo Vault inputs and outputsoffers detailed instructions on how QR code signature transmissions can be “audited.”
我们有关Cobo Vault输入和输出的文章提供了有关如何“审核” QR码签名传输的详细说明。
While Cobo Vault believes that open source does not have much meaning for enhancing the security of hardware wallets, we have still released thefirmware codefor the Cobo Vault’s Secure Element. In doing so, we enable our users to see that random numbers are generated by a true random number generator and not by a pseudorandom number generator . For a detailed explanation of the importance of random numbers, refer to ourarticleon difference between true random numbers and pseudorandom numbers.
尽管Cobo Vault认为开放源代码对于增强硬件钱包的安全性没有多大意义但我们仍然发布了Cobo Vault安全元素的固件代码。 这样而不是由伪随机数生成器生成的。 有关随机数重要性的详细说明请参阅有关真正随机数和伪随机数之间差异的文章。

在二维码支付横空出世之前,钱包是很多男人或女人生活中不可缺少的物品,而且在高端品牌中也可以是一种奢侈品,是一种身份的象征。在英语中,有两个单词 wallet 和 purse,它们都有“钱包”的意思,而且目的类似,但是定义不同。二、purse 是一种小袋子,主要由女人用来携带现金和各种日常生活用品,如化妆品等。现在使用的 purse 有很多种,它可以用来装钱包、女人的私人物品和货币,通常放在肩上,例如:
热钱包是一种需要网络连接的在线钱包,在使用上更加方便。但由于热钱包一般需要在线使用,个人的电子设备有可能因误点钓鱼网站被黑客盗取钱包文件、捕获钱包密码或是破解加密私钥,而部分中心化管理钱包也并非绝对安全。因此在使用中心化交易所或钱包时,最好在不同平台设置不同密码,且开启二次认证,以确保自己的资产安全。
LV豆豆钱包是奢侈品销量很火的一个品牌,市面上仿品快比正品多了。今天教大家几点鉴定LV豆豆钱包真假方法,小姐姐们在拿到货的时候就可以自己辨别真假哦!话不多说上干货 1.内部刻印LOGO 3、金属按钮logo刻印:正品:字体与行间距排列整齐,受力均匀无明显外溢,笔画细密自然美观且清晰明了;三排的字体大小不一致,且有明显差别;
我对那些骗子非常生气。今天我又进入了几个直播间,看到一些想赚钱的人,他们的等级还不到0级。在直播间里,有人让他们刷钱来提升等级,他们就刷了100块钱,升到15亿。他们为了升到15级,花了两个520,还说以后有能力就可以开播。但是,他们得到了什么?他们只听信了骗子的忽悠,却没有学到任何知识。骗子说得天花乱坠,却没有传递任何知识。他们只是想让你提升财富等级。如果你真的有能力,为什么不去学习知识呢?
其实在普通的异性朋友之间,送钱包可能就是一种友谊的表达,没有其他的含义,在长辈和小辈之间送钱可能还会有一些美好的祝愿,送男士钱包什么意思呢,一般小辈送长辈钱包是希望长辈可以财源滚滚,生意兴隆,过生富足的生活,而长辈送小辈钱包而是希望小辈可以从小有一个非常好的理财习惯,这样可以为以后的幸福生活打下基础。
(2)wallet是男士钱包,purse是女士钱包。英语单词wallet 和 purse 的区别如下:两个单词读音不同:wallet英 `?w?l?t` 美 `?wɑ:l?t`,purse英 美 。n.主英钱包,皮夹子。(1)purse强调是钱包,wallet强调是钱夹(折叠式的)。我把钱包麻利地塞进了他的口袋。
如果我们不慎弄丢了钱包,那么应该先冷静下来,然后及时向他人寻求帮助。学习用更多的语句来表示你弄丢了钱包:出门在外,如果不小心,难免会弄丢一些随身的小物件,比如“钥匙 key”、“手机 mobile phone”、“证件 ID”、“钱包 wallet”。I’ve lost my wallet. 我钱包丢了。
蓝色也存不住钱,因为蓝色代表水,意思是钱会像流水一样的流掉,也不适合钱包的颜色。红色,五行属火。虽是最能招财的颜色,但同样也表示花钱爽快,钱财无积蓄,而且红色代表赤字,故红色钱包不推荐(很多内行人都避免红色钱包)。运气不好的时候,可以选用红色的钱包,它具有退财消灾,逢凶化吉的寓意。蓝色,五行属水,钱财会如水般流去,竹篮打水一场空,故蓝色钱包也不宜用;白色,很干净的颜色,如果说脸上干净是好事,那么钱包干净,就很难看了,因此白色钱包更不推荐。知道这些颜色代表的含义,您可以选择适合自己的钱包了吧!希望您选对钱包
黄色钱包是很多贵族女士喜欢的钱包,黄色高贵,至上,是财富黄金的最真实表现,可以招财聚财,对于正在追求财富的人来说,是最合适不过的了,黄色钱包会让你的财运更上一步。钱包相信大家都有,有没有想过钱包也会带来你财运呢?其实钱包不同的颜色,对你的财运也有不同的帮助喔!一般来说,黑色代表沉稳,可以守住钱财,即聚财,不轻易让钱损失;咖啡色和棕色有守财的意思,同样可以聚财,因此市面上很多皮类钱包都这两种颜色为主;红色代表红红火火,是最能招财的颜色,但同样也表示花钱爽快。不过对这几种颜色比较忌讳的人不适合用其招财。
gopay钱包在中国合法吗?首先,我们需要明确的是,gopay钱包在中国是依法合规运营的。早在2017年,中国人民银行就发布了《关于依法合规开展第三方支付业务的通知》,明确规定了第三方支付机构需要经过严格审批和监管,获得合法牌照方可开展业务。gopay钱包是一家经过审批,并取得支付业务许可证的第三方支付机构,因此在中国是合法合规运营的。
