King of the Jade Empire (w/ Lawrence Nahum)
On this episode of the Unhashed Podcast we welcome Lawrence Nahum, founder of GreenAddress and Chief Architect at Blockstream, to do a deep dive on Blockstream Jade and Blockstream Green. We cover hardware security including secure elements and their alternatives, open-source supply chains, the nuances of airgappedness, and Blockstream's recent anti-exfil security mechanism. Digging into Blockstream Green, we go over the nature of deterministic wallets, private keys & recovery, 'instant confirmation' transactions, and the recent 'encrypted blob' for enhanced user privacy.
