Multisig and split backups: two ways to keep your bitcoin more secure

As CTO of Casa it's my job to examine every possible aspect of our system's architecture and understand which components are suboptimal so that we can make plans to implement improvements. No system is perfect, but by exploring the limits of the system we can design our user experience in order to steer clients down "happy paths" and away from rough edges. Casa is built upon a foundation of several pillars: geographically distributed multisig, dedicated hardware devices to secure keys, thoughtfully designed user experience, and high quality client services. The dedicated hardware devices are a unique aspect of our architecture in that Casa has no control over them - and that's the point! This lack of control is crucial to Casa's security model, but it results in a far more challenging job for our engineers. Casa supports a diversity of hardware devices and we'd like to eventually support any device that we believe meets our standards. But what are our standards?

All You Want to Know About Multisignature Wallets

In bitcoin there are several transaction types and one of them is Multisig. Multisig addresses and transactions are created from multiple private keys and can be used in multiple situations.

As another example, in large companies where several people are in charge of funds, they can create multisig addresses for company funds where you have multiple signatories. This will improve the security of the funds from both internal and external threats since no one can send a tx without the approval of other signatories. More examples of multisig applications can be found on the wiki. You can check the motivation and specification in BIP We'll also be using the Pay-to-Script-Hash P2SH format for the script and its address format for our addresses and for receiving the transactions.
