BlockTrail.com Wallet - What do you think about it ?

[neutraLTC]

You have two of the keys, therefore, access to your BTC  

I know but they don't give you that aswell lol , Only adresses are generated and nothing else . there is no way to get the private keys

Currently, the way to do this is using a PHP script that's available as part of our SDK for developers: https://github.com/blocktrail/blocktrail-sdk-php/blob/master/examples/wallet_recovery_example.php

The way the wallet has been built it shouldn't require more than a few days to also release a desktop version (the hardest part will be packaging so it can be installed easily etc). That desktop version will contain an easy way to use your backup sheet to get your bitcoins out of the wallet (we'll probably code in insight and another alternative API for it).

I also assume in case of major problems with Blocktrail that there will be some developer in the community who would create a small website that can help ppl get their BTC out, so far the community has proven itself rather helpful when others are in dire straits.

Oh it dosen't sounds so hard I assume even if I don't have any programming knowledge on PHP . too bad .NET is not that much worked on and updated .. it's 10 months old otherwise I would work on it .

We invite you to work on it if you have some extra time!

Since there is no private key I wouldn't move to blocktrail, i see that their overall platform is great.
When blockchain is down i check there the transaction if confirmed or not etc..
If you haven't seen online to sign a message then you can do through coinbase.

Blocktrail uses 2 of 3 multisig method. They control one of the key while you control two of the key. Limits can be set and it would be impossible to bypass that limit without the 2 of your keys. I don't know the technical details about signing a multisig address but it would undoubtedly be harder than standard 1 address used by coinbase.

We know how easy is just 1 address in coinbase, to sign a message there is simply.
But we should analyze the worst case what if their website goes down.
Is there any way to recover and get back our btc? Yes or No?

It is pretty standard that most exchanges or online wallet which uses a cold storage wouldn't allow the customer for their private key. Since they are backed, they can probably cover your coins if they get hacked. By giving you control over your coins in standard addresses, you will be fully responsible for your Bitcoin.

For the UI is very good, simple and easy. But i have the problem when i forget my pin.
i can't recover my pin, since there is no button to reset my pin. I think you sholud add advance setting button to reset pin and password.

Yeah that is how this should work but that does not happen all the time.
"Bter" exchange was hacked and the bitcoin were "stolen" from "cold wallet"
About the blocktrail i just installed their mobile app, the UI is perfect

What are you using , smartphone wallet because I have nothing called PIN on my side  (Web wallet) and I don't want to screw things up

you only need a pin to send bitcoin from your mobile wallet. it's an extra security for mobile apps. btw, make sure to use authy/2FA

The problem is not that. If i forgot my pin and password, there is no reset button on the app.
Since this is a service discussion topic, i think this is the best way to give feedback of the app for developer.

But uninstalling and installing the mobile app again and login with email/pass does it solve this problem of PIN?

[OmegaStarScream]

I just made a topic so you guys give your suggestions about the things that should be added to BlockTrail wallet : https://bitcointalk.org/index.php?topic=1181934.0 & yes they will be taken seriously .

Just download it after i saw this thread
I thought it was great wallet just like mycelium, but i dissapointed after saw sign up form & other feature that could show my identity

I guess i'll keep use mycelium

Hey ETFbitcoin thanks for giving Blocktrail a try, did you know you could sign up with a username instead of an email? This gives you greater privacy and doesn't link you to your identity

[smith coins]

Just download it after i saw this thread

They also sync your contact info, i dont know why do they need my contact list to be synced?

[a7mos]

I used block trail before as a block explorer only
But I did not try this wallet yet as I'm fine with block chain android wallet

On their Google Play page it says :

- 2-of-3 Multisig technology so you always remain in control of your coins
- HD wallet technology allowing you to create an unlimited number of addresses
- Send and Receive bitcoin easily with contacts on your phone
- Live update for new transactions and your balance
- View your full transaction history with the price at the time of the transaction
- Personalise your account so your friends can quickly identify you
- QR code scanning with bitcoin URI support
- Send requests via email and SMS
- PIN protection
- Anonymous accounts, for your privacy
- Transactions signed locally on your device
- Backup document incase the worst happens
- Local currency display using live price updates

So it's nothing that you should be afraid off , it's not like they are sending these informations to their servers or anything , in fact they don't store anything on their side as far as I know. only one of your private keys which is not enough to take control of your coins .

Alright, thanks. I like more the mobile app rather than the website wallet app. But what does HD wallet mean? sorry for the noob question

[OmegaStarScream]

Here is what HD wallet means basically , from the BlockTrail CTO  :

The Blocktrail wallet is a HD wallet, this means that all your private keys are generated from 1 master key, which is generated in your browser/app and then encrypted with your password before sending it to be stored on the Blocktrail servers.
Additionally the Blocktrail wallet is a multi-signature 2of3 wallet, 1 is your primary master key, 1 is your backup key and the 3rd is the blocktrail server key. 

Another results I found by searching little bit :

HD is short for Hierarchical Deterministic. Typically, bitcoin wallets generate each new bitcoin address from a unique random number, requiring you to make a new separate backup each time you create a new address. To avoid losses from lack of backups, such wallets tend to use a single bitcoin address for all transactions. HD wallets instead use a «master seed» to derive all future bitcoin addresses sequentially, with each new address created by appending a counter to the end of the seed. In this way, all the bitcoin addresses created by such wallets are «hierarchically determined» from a single seed, only need to be backed up once, and can be fully restored at any time in the future just from the backup of that single master seed. When using a single address wallet, all your transactions will be associated with a single address, and because all bitcoin transactions are public, anyone can see what addresses you are sending funds to and how much money you have. HD wallets greatly improve your privacy by being able to generate new addresses whenever you send and receive funds, making your transaction activity and total balance very hard to track.

Thanks for this research, i though that it was about the design HD lol, there is no like/thank button so i have to write Thanks very much.
