Hi folks. I do not have a hardware wallet at the moment, only an Online wallet with Blockchain.info
Does any of you know if it is possible to sign a message for non imported addresses there? Has anyone done it before on Blockchain.info?
Thanks for your help.
I assume by non-imported address it is an address where you import the private key. You can't sign a valid message from an address if you don't own the private key. So you have to "import" the private key on blockchain.info. You can use software like Electrum to sign your message, it's more secure than blockchain.info. |

Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

Thanks for your help.
To reiterate what joniboini wrote; no, you will not be able to sign a message from a Blockchain.com generated wallet. If you create a private key using one of the key generators such as bitaddress.org you will be able to import that key into your Blockchain.com account and sign a message with that key. However, that is one of the least secure methods since web wallets are prime targets for hackers. Using an off-line computer to generate a wallet using Electrum is a significantly more secure method. Only download Electrum from this source: https://electrum.org/#downloadThe official github repository is here: https://github.com/spesmilo/Be very careful when using github, as there have been fake versions, and fake update notifications that send you to a different github repository. |
