Topic: Blockchain.info online wallet (Read 1062 times)
Blockchain is probably the most popular wallet today. we use blockchain for send and receive bitcoins. The Blockchain.info is not only a popular accepted block explorer but also most popular bitcoin wallet, due to its security and utility. But that's not enough to secure us further as it's online wallet and hack attempt can be considerable.

Or, you could just import the BIP39 seed onto any supporting desktop wallet clients. For instance, copay. Though instead of "import from backup" you'd have to go to create a new wallet, and specify the recovery seed.
i have tried this before, generate a new wallet on blockchain.info, write down the walet recovery seed, and if you ever lose access to your wallet then you could either do it the hard way, go through all the derivation paths etc. or just import it into any supporting bitcoin wallet.
So yes, you can indeed access your coin without having access to the site, as long as you have the correct recovery seed.

So is it possible that I can import my online blockchain.info wallet into Electrum desktop wallet, use it to send and receive and it will automatically sync with the online blockchain.info wallet? or do I have to create another wallet online and then import it in Electrum, and would sync the transactions and the balance then?
If this is possible it will save me moving the coins back and forth every time I want to sell on blockchain.info
You have made a serious mistake here. You are neither "linking" your Blockchain.info wallet when importing seed into Electrum or another BIP39 supported wallet nor are you "sending" Bitcoin to another wallet. You are "IMPORTING". So, NO, you can't sell from Electrum or any other wallet DIRECTLY. If you want to sell Bitcoin, you have to login to Blochchain.info.
When you import, all your addresses and private keys corresponding to them are created. Seed/private key is a *key* to access your Bitcoin. If you compare a seed to a key to a locker, then importing your seed into another wallet means making an EXACT copy of your *key*. Therefore, as long as you don't delete your wallet in Blockchain.info, you can use it just like before.
Important: I HIGHLY recommend NOT to use 2+ wallets/softwares for same seed at the same time. It could lead to reuse of addresses and double-spend. It is absolutely not for newbies.
One a side note, Blockchain.info is NOT an exchange. They are using other services for everything beyond a "wallet".
Edit:
You can backup your bitcoin wallet address private keys from blockchain and importing it into electrum..
Try to watch this video ow to backup or exporting your private keys.. https://www.youtube.com/watch?v=fcXePXbrI4U
And this is how to import the private key in electrum wallet http://www.thecleverest.com/importing-bitcoin-from-a-paper-wallet-into-electrum/
The paper wallet is just a sample as blockchain and import your own private keys into electrum once blockchain is down you can import it anytime in any wallet you want to recover your funds..

Blockchain.info does not support exporting private key from a hierarchical deterministic(HD) wallet. Exporting private key is only for imported keys (or addresses from your Blockchain.info old account). You have to export your seed if you want to backup your HD wallet (default wallet).
Thanks for pointing it out! But please specify more details next time to avoid confusion!

Just for the record... it appears that blockchain.info is using the "BIP44" Derivation Path (m/44'/0'/0'/0) to generate addresses... I just created an account... chucked the 12 word seed into the BIP39 Mnemonic page (https://iancoleman.github.io/bip39/) and the addresses match up when you leave the Derivation Path as "BIP44".
The good news is that this means you should be able to put this seed straight into a number of other clients like Mycelium to be able to recover your wallet. Even Electrum will let you "restore" this seed if you select "Options -> BIP39 Seed" when doing the seed input.

Excellent, thank you very much for this gold information and instructions. I knew there was a way but its quite advanced and it will take me a while to study them though!
So from what I understand I can convert my blockchain.nfo 12 word passphrase in to a seed or private keys by using the bip39...right?
12 words you get from blockchain.info is BIP39 seed.
You can also restore your blockchain.info wallet using/into other wallets with corresponding seed.

According to my experience with blockchain.info . It is a safe online wallet if you will save your password and your 12 words provided from them for the recovery of your account while if you lose them then no one will be able to recover your wallet.
Your wallet's seed(12 words) is enough to recover your wallet.
In this case better is that you join any other online wallet.
All wallets, regardless of online, offline or hardware, you need a backup. Once lost, you won't be able to recover your Bitcoin. Besides, there aren't any other online wallets which allow us to access private keys.
For long term storage never ever use online wallet and no one know about their mood and their future.
And in the last as everyone said you will never access to your bitcoin in the time when they go down and any site often face that issue so try to keep some of your funds in any other wallet too as you may need them in any emergency
And in the last as everyone said you will never access to your bitcoin in the time when they go down and any site often face that issue so try to keep some of your funds in any other wallet too as you may need them in any emergency
Really now? Did you really read this thread? We all said you can recover Bitcoin even if blockchain.info goes down. Even the post just above yours mentioned recovering wallet is possible. Sigh...
As long you have a backup of wallet or seed, you can recover your bitcoins even if their site goes down.
Now that is interesting!
So lets assume blockchain.nfo site is down. What would you do to recover the wallet?
I have only the recovery 12 word phrase and the password. I haven't seen any private keys!
https://iancoleman.github.io/bip39/. Download a local copy and then use it. You can see it generate same address you have in your wallet. You can also use Electrum, Mycelium or Bither to recover your Bitcoin from seed.
Blockchain.info is now an HD wallet. If you don't know what that means, read http://support.mycelium.com/hc/en-us/articles/207045475-What-does-HD-in-HD-Wallet-mean and/or http://www.fintechblue.com/2016/03/what-is-an-hd-wallet/.
The password you are referring to is the one you use to sign in, right? If so, when you recover later, if password is asked, don't enter any because you don't need password to recover from a seed.
Note: Create a new wallet in Blockchain.info for testing. Don't expose seed or send it to anyone. Getting your seed means having access to your Bitcoin, just like private key.
Edit: if you just want to check whether the addresses created in another wallet is same as in Blockchain.info, then you can use xPub key. To do it, follow:
• Go to blockchain.info/wallet and login.
• Click menu.
• Click 'Settings'.
• Click 'Addresses'.
• Click 'Manage' of the wallet you use or want to export your xPub key.
• Click 'More Options' and select 'Show Xpub' from drop-down list.
• Click 'Confirm'. The long time starting with "xpub" is extended public key(xPub) of that account.
• Copy/save your xPub.
• Now, go to iancoleman.github.io/bip39/ or open local file if you have downloaded it(recommended).
• Paste xPub in 'BIP32 Root Key'.
• Select 'BIP32' in 'Derivation Path'.
• Addresses will now be created and you can see your addresses in generated ones.
Note: Your xPub must never be shared with people other than you trust because once someone has your xPub, they can track all your transactions corresponding to that key.

Must be the answer I have been looking for. One noob question here : How a seed will be related to all the address which were created afterwards within blockchain.info wallet. (I am aware of some encrypted one private-key format produced 3 to 4 bitcoin addresses) hierarchical deterministic works this way ?
I didn't understand the bolded part. Please explain or give an example!
If you don't understand what is a HD wallet, please read http://support.mycelium.com/hc/en-us/articles/207045475-What-does-HD-in-HD-Wallet-mean, http://www.fintechblue.com/2016/03/what-is-an-hd-wallet/ and https://bitcoin.stackexchange.com/a/21200.
tl;dr - all your keys can be generated from your seed.
And two more : blockchain.info's previous version seed also into BIP39 compatibility ?
If you are talking about passphrase, then no! It is *not* BIP39 seed.
I have not tried copay, do we have any other wallets with support of BIP39 seeds ?
Mycelium, Bither, Schildbach's wallet and many other. See https://bitcointalksearch.org/topic/deterministic-wallet-compatibility-matrix-1000544 (might be outdated).
Edit: Please note that although many wallets support BIP39 seed, wallets may not be compatible with each other. Because there is paths when generating keys which is usually called key derivation path. Some wallets use key derivation path different from other wallets. However, most (popular) wallets support recovering wallets even if they use different key path.
It is safe blockchain . Actually i am using it and i am planning to open more wallets . But i think that is a cloud wallet and if they are losing their servers burning etc , practically our money are done
Did you even *read* this thread?
Also i got some problems with blockchain last time , they have diminished the mining fee and my transactions were stuck 8 days . I tried to push my transactions , i sent to support mails but no help , and i had to wait 8 days for a confirmation . So sometimes is good sometimes is bad.....
You set a fee yourself in Blockchain.info iiirc. Using an excessively low fee may make result transaction not to be included in a block or may take a long time to get included. Alternatively, using an excessively high fee would only be you wasting your Bitcoin. You can do it If you want to "tip" miners a bigger amount. https://jochen-hoenicke.de/queue/#24h

I had moved them to the blockchain wallet before so I can sell immediately if the price crash. I only have the recovery phrase but I understand now that the site has to be running in order to do a recovery if necessary!
As long you have a backup of wallet or seed, you can recover your bitcoins even if their site goes down.
So I moved them now back to my Elecrum wallet. I guess better safe than sorry!
Thank you all for your advice
Thank you all for your advice
If you have moved bitcoins, then is alright. But if you have moved private keys from/to Blockchain.info wallet, I recommend you to create a new address in Electrum and send all your funds to it.

Hi,
Is blochchain.nfo online wallet safe?
It's not safe but not worst either. Back to the user if they can keep their credentials and backup their passphrase at least unwanted things could be avoided. But, make sure you can access your private key in the first place.Is blochchain.nfo online wallet safe?
Can I still access my BTC if the site go down for any reason?
No. Unless you have the private key.

The site is down how can you even login in the first place.
The term safe is a big deal for online exchanges. All exchanges are prone to shutdown even the regulated one. Just use their features that suits your needs but never intend to used it as a long term wallet or for storage purposes.
"We are a noncustodial wallet and do not have access to your bitcoins. This means we cannot view your total balance, make payments on your behalf, or prevent you from accessing your wallet. With a Blockchain wallet, you retain complete ownership of your bitcoin."
So I thought that means I can access the coins from outside somehow?
Is blockchain.nfo regulated?
If not which sites are regulated?
If I were you just don't use any web wallet and stay in a secured wallet like electrum desktop wallet and install a strong antivirus into your device so you can assure that you are safe and it's your responsibility to secure your wallet
Hi,
Is blochchain.nfo online wallet safe?
Can I still access my BTC if the site go down for any reason?
It can be considered safe but I recommend you to use electrum like desktop wallet that will never share your private keys with their server. All online wallets including blockchain.info can be vulnerable so just use electrum or mycellium rather than any other online wallets. Is blochchain.nfo online wallet safe?
