无核比特币安全的危险和前景

这一周期的一个基本主题是挑战关于世界各地人们如何使用比特币的先入为主的观念。

As the dust settles on another Bitcoin bull cycle, conversations among Bitcoiners have centered around the emerging trends shaping the use and adoption of the leading cryptocurrency. While some trends, such as the integration of hardware wallets and the rising popularity of multi-signature setups, have been widely covered, others, like the seedless security model, have flown under the radar.

随着另一个比特币牛市周期的尘埃落定，比特币爱好者之间的对话集中在塑造领先加密货币的使用和采用的新兴趋势上。虽然硬件钱包的集成和多重签名设置的日益普及等一些趋势已被广泛报道，但无种子安全模型等其他趋势却没有受到关注。

In this installment of Bitcoin Tech Talk, we explore the seedless security model, examining its advantages, challenges, and potential to revolutionize the way people self-custody their Bitcoin. We also speak with Bitcoin product developers who are pioneering new approaches to seedless backups and uncovering the latest innovations in mobile self-custody.

在本期比特币技术讲座中，我们将探讨无种子安全模型，研究其优势、挑战以及彻底改变人们自我托管比特币方式的潜力。我们还与比特币产品开发人员进行了交谈，他们正在开创无种子备份的新方法，并揭示移动自我托管的最新创新。

One of the biggest pain points in Bitcoin self-custody that we haven't really solved yet is how to securely back up your private keys. Mnemonic seed phrases are the current standard for self-custody, but they're also a major attack vector for phishing scams and other attempts to steal users' funds.

我们尚未真正解决的比特币自我托管的最大痛点之一是如何安全地备份您的私钥。助记词种子短语是当前自我保管的标准，但它们也是网络钓鱼诈骗和其他窃取用户资金的尝试的主要攻击媒介。

In this episode, we'll be talking about seedless security models, which take a radically different approach to securing Bitcoin private keys. We'll also be hearing from Bitcoin product developers who are pioneering new approaches to seedless backups and uncovering the latest innovations in mobile self-custody.

在本集中，我们将讨论无种子安全模型，它采用完全不同的方法来保护比特币私钥。我们还将听到比特币产品开发人员的声音，他们正在开创无种子备份的新方法，并揭示移动自我托管的最新创新。

Before we get started, let's quickly define what we mean by "seedless security models." In the context of Bitcoin, a seed refers to the 12- to 24-word mnemonic phrase that's used to derive your private keys. These seed phrases are a convenient and portable way to back up your private keys, but they also introduce a new point of failure if they're compromised.

在开始之前，让我们快速定义一下“无种子安全模型”的含义。在比特币的上下文中，种子是指用于派生私钥的 12 到 24 个单词的助记词短语。这些种子短语是备份私钥的便捷且便携的方式，但如果它们被泄露，它们也会引入新的故障点。

Seedless security models, on the other hand, aim to eliminate the need for mnemonic seed phrases altogether. Instead, they use a variety of techniques to securely store and back up your private keys without ever exposing them to you. This makes phishing scams and other attempts to steal your seed phrase irrelevant,大幅提升了安全性.

另一方面，无种子安全模型旨在完全消除对助记种子短语的需求。相反，他们使用各种技术来安全地存储和备份您的私钥，而不会将其暴露给您。这使得网络钓鱼诈骗和其他窃取您的助记词的尝试变得无关紧要，大大提升了安全性。

There are a few different approaches to seedless security models, and in this episode, we'll be taking a closer look at two of the most promising ones: server-sided seedless backups and client-sided seedless backups.

无种子安全模型有几种不同的方法，在本集中，我们将仔细研究两种最有前途的方法：服务器端无种子备份和客户端无种子备份。

Server-sided seedless backups are a good option for users who want the convenience of a fully托管式解决方案. With this approach, your private keys are encrypted and stored on a server, and you can access them later on any device with an internet connection.

对于想要享受完全托管式解决方案便利的用户来说，服务器端无种子备份是一个不错的选择。通过这种方法，您的私钥将被加密并存储在服务器上，您稍后可以在任何具有互联网连接的设备上访问它们。

The main advantage of server-sided seedless backups is that they're very easy to use. You don't have to worry about generating or storing a seed phrase, and you can be up and running in just a few minutes. However, the downside of this approach is that it introduces a third-party custodian into the equation, which some Bitcoiners may be hesitant to trust.

服务器端无种子备份的主要优点是它们非常易于使用。您不必担心生成或存储助记词，只需几分钟即可启动并运行。然而，这种方法的缺点是它引入了第三方托管人，一些比特币持有者可能不愿意信任第三方托管人。

Client-sided seedless backups, on the other hand, are a more advanced approach that gives you more control over your private keys. With this approach, your private keys are encrypted and stored on your own device, and you can back them up to any location that you choose, such as a cloud storage service or a hardware wallet.

另一方面，客户端无种子备份是一种更先进的方法，可以让您更好地控制私钥。通过这种方法，您的私钥将被加密并存储在您自己的设备上，您可以将它们备份到您选择的任何位置，例如云存储服务或硬件钱包。

The main advantage of client-sided seedless backups is that they're more secure than server-sided backups since your private keys never leave your device. However, the downside of this approach is that it's more complex to set up and use, and you'll need to take extra care to ensure that your backups are stored securely.

客户端无种子备份的主要优点是它们比服务器端备份更安全，因为您的私钥永远不会离开您的设备。但是，这种方法的缺点是设置和使用更加复杂，并且您需要格外小心以确保安全存储备份。

Now that we have a basic understanding of seedless security models, let's hear from some of the Bitcoin product developers who are working on the front lines of this new technology.

现在我们对无种子安全模型有了基本的了解，让我们听听一些在这项新技术第一线工作的比特币产品开发人员的看法。
