Q & A

What is Casa and what problem does it aim to solve?

Casa is a company that specializes in multi-signature (multisig) technology for Bitcoin security. It was created to address the challenge of securing private keys, especially for larger amounts of Bitcoin, by providing a system that reduces the risk of loss or theft through the use of multiple keys.

How does multi-signature custody work in the context of Casa?

Multi-signature custody with Casa involves having multiple keys that protect a single pool of Bitcoin. To spend the Bitcoin, a certain number of these keys (for example, two out of three) are required to approve the transaction, providing a layer of security against loss or theft.

Why did Casa decide to incorporate a mobile app into its multisig solution?

Casa decided to include a mobile app in its multisig solution to provide a resilient and convenient key that can be encrypted and backed up to the cloud, reducing the risk of losing access to the key. The app also contributes to a more controlled and secure environment compared to a browser, especially for holding one of the necessary multisig keys.

What is the significance of Casa's approach to not being a financial service company?

By not being a financial service company, Casa is not required to perform KYC (Know Your Customer) procedures for its users, allowing for greater privacy. It also means Casa does not have control over users' assets, which is important for maintaining the principle of self-custody.

How does Casa address the concern of trusting a company with one of the multisig keys?

Casa addresses this concern by ensuring that the key it holds is not enough to move funds on its own. Even if Casa's key is compromised, the funds cannot be accessed without the other keys. Additionally, Casa has a feature called 'Sovereign recovery' that allows users to recover their Bitcoin even if Casa is no longer available.

What is the process for inheriting Bitcoin through Casa's system?

Casa has an inheritance planning tool that allows users to designate a family member or a friend to inherit their Bitcoin. The designated person can request access to the Bitcoin after the owner passes away, which starts a six-month timer during which the original owner can revoke the request if they are still alive or if something seems amiss.

Why is it important for Casa users to consult with an attorney about inheritance planning?

Consulting with an attorney is important for Casa users to understand the legal and tax implications of inheritance planning, especially to ensure that the transfer of Bitcoin aligns with estate planning laws and to avoid potential issues down the line.

What is the philosophical reason behind Casa's encouragement for users to self-custody their Bitcoin?

Casa encourages self-custody of Bitcoin because it aligns with the core principles of Bitcoin, which include individual control and freedom. Self-custody allows users to have direct control over their assets, which is a significant advancement in financial autonomy.

How does Casa's approach to Bitcoin security compare to traditional financial institutions?

Casa's approach to Bitcoin security differs from traditional financial institutions by offering a decentralized and self-sovereign model. It provides tools for individuals to secure their own Bitcoin without relying on a central authority, reducing systemic risk and enhancing personal control over one's assets.

What is the 'Sovereign recovery' feature in Casa's multisig setup and why is it important?

The 'Sovereign recovery' feature in Casa's multisig setup allows users to recover their Bitcoin even if Casa is not available. It is important because it ensures that users maintain full control and access to their funds, regardless of the status or existence of Casa as a company.
