Thanks. I did it twice with Bitcoin Core v0.15.0.1 and no idea why it doesn't work when I try to verify on coining, anyway on btc core the message has been verified.

There is an old meta thread requesting this to be stickied, it was declined. I doubt asking again would yield a different answer.


Big thanks to everyone helping out here, verifying messages and answering questions.

There are many ways to do this but the easiest would be to download a wallet that has that feature, like Samourai Wallet, and look into how you can do that on their site.

I don't think there is a way to do it to prove that you own an email address as such... signing only allows you to prove that you are in control of a private key/bitcoin address.


sorry but i use exchanger wallet how can i get the private key ?
The simple answer is that (generally) you can not get the private key for addresses controlled by exchanges, thus you can not sign messages for exchange wallet addresses. Get a "proper" wallet where you can access the private keys Tongue

Wow, this is a great tutorial shorena! I think mods should sticky this, because every new user have to learn this basic thing before it's too late. I see a lot of users got hacked or lost password and they end up losing their account forever.

AFAIK you can't do it with new blockchain.info wallet, because they doesnt give the private key to us, so you can try with other way. with other wallet maybe never know i still use my old bitcoin address on blockchain.
