Understanding the Latest Updates to BitBox

In June 2023, the BitBox hardware wallet introduced a series of updates known as the Bellinzona Update, focusing on both enhancing security features and improving user experience. This article will explore the key changes and their implications for users.

The Origin of the Bellinzona Update

The Bellinzona Update derives its name from a tradition where updates are named after Swiss Alpine huts or locations. This particular update is named after Bellinzona, a city in the Swiss canton of Ticino, reflecting the development team’s connection to the Swiss Alps and their culture of strategic planning and innovation.

Improved bitcoin and litecoin amounts

In the recent Bellinzona update, we have added the possibility to display bitcoin amounts in satoshis to improve readability. Now we have improved the legibility of amounts for bitcoin and litecoin without the need to change the unit.

Bitcoin and litecoin amounts will now be displayed with the correct amount of trailing zeroes, so you can easily convert from bitcoin to sats.

Key Security Enhancements

One of the standout features of the Bellinzona Update is the improved handling of the seed phrase, which is a crucial component of wallet security. The seed phrase, typically 24 words, is now stored in an encrypted form even when the BitBox is in use. This enhancement means that:

• The seed phrase remains encrypted in the device’s memory, adding an extra layer of security.
• It is only decrypted momentarily when needed, such as during a transaction signing process.
• This approach ensures that even if someone attempts to read the memory of an active BitBox, the seed phrase remains protected.

This update is part of a broader security philosophy known as “defense in depth,” which involves multiple layers of security to protect against various potential vulnerabilities.

Flexible Seed Phrase Options

Users now have the option to choose between 12 and 24-word seed phrases. While 24 words have been the standard, offering greater redundancy and security, 12 words can be more convenient and easier to manage. This flexibility is particularly beneficial for:

• Users who prefer simplicity or need to manage multiple wallets efficiently.
• Those using steel wallets for physical backups, where fewer words mean fewer plates or easier management.
• Users who opt for brain wallets, although this method is generally not recommended due to the risk of forgetting the seed phrase.

Despite the convenience of 12 words, 24 words remain advisable for maximum security, especially for users who prioritize redundancy and robust protection.

Simplified Backup Process

A significant usability improvement is the optional nature of the microSD card backup. Initially, BitBox required users to back up their wallets using a microSD card, providing a simple and quick setup process. Now, advanced users have the option to skip this step and directly note down their seed phrases if they prefer.

This change accommodates both beginners and advanced users by:

• Allowing beginners to benefit from a quick, easy setup with the microSD card.
• Providing an option for experienced users to manage their backups manually if they have specific requirements or prefer not to use digital backups.

Account Limitation and Wallet Management

Another crucial aspect of the update addresses the differentiation between accounts and wallets. The BitBox now supports various account limitations to help users manage multiple wallets more effectively. This feature is particularly useful for users who want to:

• Create and manage multiple wallets on a single device.
• Separate different types of transactions or funds across different wallets.

However, it’s important to note that reducing the number of seed phrase words for existing wallets is not feasible due to cryptographic constraints. Users wishing to switch from a 24-word to a 12-word seed phrase must create a new wallet and transfer their funds accordingly.

Conclusion

The Bellinzona Update brings substantial improvements to the BitBox hardware wallet, reinforcing its position as a leading secure and user-friendly option in the market. By focusing on both security enhancements and usability improvements, the BitBox team ensures that users can protect their assets while enjoying a seamless experience. Whether you are a beginner or an advanced user, the new features cater to a wide range of needs, making the BitBox a versatile choice for securing your cryptocurrency.
