This video is by far the best intro to a btc wallet that i have ever seen. This is also the best wallet i have ever heard of. Excellent, Ben!!!

This is open source and likely to get some advanced features like liquid, satellite integration for sending messages and they are working on integrated coin control like found in electrum or core

Really interesting. My first opportunity to learn more. My thanks to Reddit community for link.

Great video, one point of clarification as I understand it with the 2 of 2 signature scheme . By definition, if its a 2 of 2 multisig than both signatures are always needed to sign a tx, even if it doesn't meet the threshold you set . This has several implications, If blockstreams server is down you will not be able to sign a tx, restore a seed (inside the nlocktime), or create a wallet even without any 2fa use and even if you use your own full node . Now to be fair this is the same problem with many spv wallets (exception electrum where you can toggle servers) but still an issue of inconvenience on rare moments . This is specifically why they are creating single sig setting ... and IMHO it would be nice to have multiple wallets some 2 or 2 and others single sig on different cards withing green wallet

I allways have two identical Phones. The older One and the new One with the same Authenticator codes on it and also the same Bitcoin Wallet with the same private Key (Seed). The older one never leaves my Home and it is allways offline and switched off. When the new One got stolen or lost. I can immediately reach my Bitcoin without Problems. I switch the older One on and have Access.

Another solid product from Blockstream.

A few suggestions:

1. You set up Google Authenticator but don't discuss backing up the 2FA manual key. If you lose the 2FA device, all services in Google Authenticator must be set up from scratch. If you don't have the manual key, you won't be able to set it up again without going through a 2FA reset process with Blockstream; not sure how Blockstream handles verifying that, exposing credentials, KYC, etc.

2. The option to connect to my node isn't available on the iOS app -- no "Advanced" settings. Seems like that is only an Android option (like Samouri), which should be pointed out.

3. You mention connecting Green to a Casa Node. I run a Casa Node and am pretty sure it's not possible to accept external connections because it sand boxes Bitcoin Core to only the local Lightning node.

Can you send to a Venmo account or bank account? How do you do that?

[sanisidrocr]

They will be releasing single sig option soon too . right now only 2 of 2 and if imported from desktop 2 of 3( this will be added to android soon.) Sats has already been added to the next release as well

[gasolinman]

Is it still Only for Bitcoins or are other coins/tokens available to send and receive???? and you also forgot to mention that it is a good idea to save the 2FA setup key somewhere safe so you have it in case you loose your phone or need to restore your phone, , i know you said we could set up an extra 2FA like SMS but i have example all my 2FA setup keys safely stored on a extern USB stick easy to acces on a device not connected to internet and restore all your 2FA keys in case of lost 2FA.

Thank you for your explanations oh how use wallets. Is it possible to transfer funds from your BTC to another wallet altogether? If so, can you please assist me step by step?

[karozagorus]

I never received or sent anything with Green yet, thanks for showing, really enjoyed the showcase.

[ovniologo]

2 questions, lets say i lost my phone i can just use my words and start over again using any other wallet service and recover my funds right? And if i set 2 multi factor one for .01 and any bigger i have to use the second 2mfa but if anyone had my first 2mfa they can just do multiples .01 until they drain the wallet right?

Please, how can I log in to my green Bitcoin wallets on my laptop 💻

[laurawilhelm]

Is there a way to make a payment on the machine without a wallet or smartphone?

[Tchairdjian]

Confused about the 2FA Authentication using Google for amounts larger than the threshold/ If I lose my iphone, doesn't the person who stole my iphone also has access to the Google Auth app on my phone (assuming they can hack into it)? Or are you talking about just if I lose my iPhone? Is the solution to keep a safe copy of the Recovery code for the Google Auth app so I can set up that app on my replacement phone too?

[vicdesotelle]

If they have one of my keys, what if blockstream goes out of business?

[victoroviedo]

Excellent video my friend!! I just suscribed

I like your explanation of the wallet setup, but you lost me on enabling 2FA va SMS. Sure it's easy, but it's also easy for me to SIM-swap your number and reset your 2FA. So please don't use text-based or call-based 2FA. It is as secure as your social engineering skills on AT&T/Verizon/Sprint employees. :)
