All fiat assets are being depreciated and everyone knows it.

For the first time in history, we the people built an alternative: #Bitcoin. A global, decentralized money owned by everyone. An open-source exit door.

This will never happen again. Don't look back with any regrets.

Have bitcoiners heard of #nostr?

Yes, but it can also verify currently installed apps too.

Installing an app from an APK file is trust on first use. All apps are signed by a certificate from the app developer which the OS trusts. Apps can only update if it is both a newer version, and it is signed by the same certificate it came with.

Updates are verified by only allowing updates from that same developer's certificate. If it doesn't match, it will fail. This prevents installing a fake or malicious update.

AppVerifier checks the apps you installed are have the genuine certificate and package name from the developer. It can compare to keys you provide or it can check from an internal database of apps in the app if there is an entry for it.

ITS ABOUT TO GO DOWN!!

Green is the most secure way to hodl #Bitcoin on an internet-connected device. Why? By adding a 2FA-protected account layer, stealing funds from a compromised device is virtually impossible.

Version 2.0.8 elevates this non-custodial service even more! ⬇️

When a two-factor authentication (2FA) protected account is created, multiple keys are now required to send a transaction.

The first key is on the device, protected by a PIN code and should be backed up on metal as a 12 or 24-word recovery phrase and kept in a secure location. The second key is held on the Blockstream Green servers protected by 2FA. This is the standard 2-of-2 multisig setup.

Green 2FA protected accounts also allow for 2-of-3 multisig setups where another key is kept on a Blockstream Jade in a secure location for use in recovery.

When setting up a 2FA protected account on Green, it is wise to set up multiple methods on separate devices. This ensures that as long as access to one is retained, the bitcoin will be spendable, and lost 2FA methods can be disabled or changed.

To keep users in control, if all 2FA methods fail, the 2FA protection will expire in 51,840 blocks (~1 year) since the protected coins last moved.

This update adds real-time alerts for upcoming 2FA expirations and introduces a smoother coin control flow for better privacy when refreshing 2FA protection.

System alerts have also been improved, offering clearer notifications during logins and updates on security matters. Additionally, the system architecture has been upgraded to Qt 6.7.2, enhancing the app's performance and stability for a superior user experience.

Green is fully open-source, and in that spirit, there is an open-source recovery tool called garecovery that can recover funds in the event that the 2FA protected account service is permanently terminated.

Find Green on the app store and start exploring 2FA for funds that you take on the road.
