Powering an estimated 5-10% of all Bitcoin transactions, Electrum is one of the leaders of the Bitcoin wallet space. The open-source walled was started in 2011 and played a key role in the development of the light-weight SPV wallets. Developer Thomas Voegtlin joined us for a discussion of Electrum, their recent 2.0 release and the rapidly evolving Bitcoin wallet space in general.

Topics covered included:

- The evolution of Bitcoin wallets and what motivated him to start Electrum

- Electrum 2.0 and its new features such as Multi-sig and hardware wallet support

- The security tradeoffs between using an SPV wallet versus a full node client

- How Bitcoin aliases could do away with Bitcoin addresses
