[GUIDE] How to Sign/Verify message in NEW Blockchain Wallet

[HCP]

I think it is important to note that this only works for IMPORTED SPENDABLEaddresses... You cannot sign messages with addresses created in the new beta wallet and, for obvious reasons, you cannot sign messages with addresses that you don't have the private keys for.

As you can't (yet?) access the private keys for the addresses created in the new wallet (I'm not sure if Blockchain.info are going to add this feature in the future or if it is gone for good), you cannot sign messages with any new addresses created.

So, the feature seems to be only half-implemented at present.

Does blockchain.info still on it's beta version or is it already the final version which is latest? Yeah, so now I am using that wallet rarely, I already switched on the other. Well, for me it is okay to use because of the security especially the 2FA.

I think its still in their beta mode, they will release information once they are updated.

Glad to see the signing message option on the new blockchain.info wallet is added finally. And thanks for the nice and simple guide, this will be useful for those who were asking how to sign a message on the new wallet.

It was already their since the new bet version released. I guess you did not know before how to sign message from new bet-wallet.

@OP nice work, I was thinking to make a thread like this but i was busy with some work. Keep up the good work!

Yes,you can't go back once updated.Alternative,if you can make a new account and import the addresses from the new unwanted wallet to the recently created one,you can still use it the old way.However in the coming days,blockchain.info will move all the existing wallets to the new ones.So better get used to it.Earlier signing messages was not supported in the new wallet,now it does,no reasons as to why one shouldn't use the new wallet except the UI,it sucks.

For the meantime you can use other wallet like electrum, bitcoin core and there's more. But we can still use blockchain.info if we don't prioritize the signing a message. It has already a better security features for this beta version.

1 question,

I got few address used in my NEW Blockchain Wallet, but when I go ''Imported Addresses'', I can only find 1 address in there...

but I want to / need to use the other address to sign a message, what should / can I do? Did I do something incorrect?

Your question is confusing... The imported address is the old one. So if you find only one in your imported address meaning to say that is your only address and nothing more. The other address you are referring will be find in your New address. You use the new address to sign a message. Hope it helps.

It took me 15 minutes to find that out as blockchain hasn't yet updated their FAQs and they still show the old blockchain wallet answers. They have placed this option under Settings that's tough to figure out and they should have mentioned this as a separate option or on the home page itself.

Please let me answer your question in behalf of OP. You can no longer get the private keys of your address in new blockchain.info, is not supported anymore. So you can try other bitcoin address that give the private key. But for me, blockchain is still guarantee because of its security features.

As you backread, you will read my post (above your post actually) that signing message in the new blockchain.info (new address) is a big issue indeed. I already experience that but I don't think so that others can do that.

OMFG !! Thank you so so much ! I have been looking everywhere for how to do this and I couldn't find it anywhere. Why can't they just have a guide on their site ? Well thank you it's actually very simple ^^

Im trying to find the 'more options' bit on blockchain.info, it seems they update this so often.  People use sign messaging often why not have it more clear blockchain.

Try to go to "Imported Address", if you have any Spendable Addresses you can sign a message with it.
Or you can also add a new address there if you have the private key by clicking the "Import Address" button.

OK i can try this, but do you know if im a fresh user just signed up to blockchain.info are you are to sign the default address they give you? (you used to be able to)
