Blockstream Green Wallet Review
GreenAddress Bitcoin mobile wallet is now rebranded as Blockstream Green. The app is already available for download for both Android and iOS devices, with more platforms on the way soon. The code for both apps is also open source and available on GitHub. Like GreenAddress before it, Green wallets use 2-of-2 multi-signature by default, with one key held on the device, and one key held on Blockstream’s servers. This allows achieving application-based Two-Factor Authentication (2FA) so that if the user device gets lost or stolen, attackers are unable to spend its funds (it is recommended that the user hold its 2FA on a separate device).
It's a fast growing wallet, I feel lack of stability here, a couple of time I was thrown out of the app, but it can be fixed. I like the design and simple interface. Hoping to see new updates.
