無核比特幣安全的危險與前景

這個週期的一個基本主題是挑戰關於世界各地人們如何使用比特幣的先入為主的觀念。

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.

隨著另一個比特幣牛市週期的塵埃落定，比特幣愛好者之間的對話集中在塑造領先加密貨幣的使用和採用的新興趨勢。雖然硬體錢包的整合和多重簽名設定的日益普及等一些趨勢已被廣泛報道，但無種子安全模型等其他趨勢卻沒有受到關注。

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.

在本期比特幣技術講座中，我們將探討無種子安全模型，研究其優勢、挑戰以及徹底改變人們自我託管比特幣方式的潛力。我們還與比特幣產品開發人員進行了交談，他們正在開創無種子備份的新方法，並揭示行動自我託管的最新創新。

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.

我們尚未真正解決的比特幣自我託管的最大痛點之一是如何安全地備份您的私鑰。助記詞種子短語是當前自我保管的標準，但它們也是網路釣魚詐騙和其他竊取用戶資金的嘗試的主要攻擊媒介。

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，我們將討論無種子安全模型，它採用完全不同的方法來保護比特幣私鑰。我們還將聽到比特幣產品開發人員的聲音，他們正在開創無種子備份的新方法，並揭示行動自我託管的最新創新。

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.

在開始之前，讓我們快速定義一下「無種子安全模型」的含義。在比特幣的上下文中，種子是指用於派生私鑰的 12 到 24 個單字的助記詞短語。這些種子短語是備份私鑰的便捷且便攜的方式，但如果它們被洩露，它們也會引入新的故障點。

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，無種子安全模型旨在完全消除對助記種子短語的需求。相反，他們使用各種技術來安全地儲存和備份您的私鑰，而不會將其暴露給您。這使得網路釣魚詐騙和其他竊取您的助記詞的嘗試變得無關緊要，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.

無種子安全模型有幾種不同的方法，在本集中，我們將仔細研究兩種最有前途的方法：伺服器端無種子備份和用戶端無種子備份。

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.

對於想要享受完全託管式解決方案便利的用戶來說，伺服器端無種子備份是一個不錯的選擇。透過這種方法，您的私鑰將被加密並儲存在伺服器上，您稍後可以在任何具有網路連線的裝置上存取它們。

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.

伺服器端無種子備份的主要優點是它們非常容易使用。您不必擔心生成或儲存助記詞，只需幾分鐘即可啟動並運行。然而，這種方法的缺點是它引入了第三方託管人，而一些比特幣持有者可能不願意信任第三方託管人。

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，客戶端無種子備份是一種更先進的方法，可以讓您更好地控制私鑰。透過這種方法，您的私鑰將被加密並儲存在您自己的裝置上，您可以將它們備份到您選擇的任何位置，例如雲端儲存服務或硬體錢包。

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.

客戶端無種子備份的主要優點是它們比伺服器端備份更安全，因為您的私鑰永遠不會離開您的裝置。但是，這種方法的缺點是設定和使用更加複雜，並且您需要格外小心以確保安全儲存備份。

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.

現在我們對無種子安全模型有了基本的了解，讓我們聽聽一些在這項新技術第一線工作的比特幣產品開發人員的看法。
