Keeping Bitcoins safe from theft is probably one of the things Bitcoin holders worry the most about. Historically, there have been a number of recommended best practices like paper wallets, BIP 38 wallet cards and cold storage. Although these remain relatively safe ways to store Bitcoins, implementing these solutions can be complicated and difficult to manage for day-to-day transactions. Recently, some companies have begun introducing multi-signature HD wallet services, where 2-out-of-3 signatures are required to sign transactions. These solutions offer security and usability, with the assurance that Bitcoins will remain safe, and the ability to transact with ease. In fact, the website P2SH.info tracks the adoption of multi-sig, and it has been growing exponentially in recent months.

Which brings us to our guest: Arianna Simpson, an Account Specialist at BitGo, a company that provides a simple multi-signature HD wallet solution for individuals and businesses. We talked to Arianna about BitGo and the services they offer, discuss different use cases for multi-sig HD wallets and make projections about the evolution of the wallet space from different angles.
