I am still not able to verify your signed message "Message failed to verify!"
Maybe there is some space or double quote that you have lost by mistake? Which wallet are you using for signing this message?

[Martin958]

Electrum 4.1.2 - I downloaded it to Windows desktop 30 minutes ago


If I do it on my wallet it says Signature verified

Sorry to nitpick, but I think the whole point of this thread is securing the ownership of a bitcoin address. What is the point of signing a NEW address without proof of ownership of the OLD address?

I think we should do like this:

<Link to old verification>

Adding a new address:

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
I am fillippone from bitcointalk.org forum.
Today is March, 20th 2021 and I want to secure my bitcointalk.org account with this message.

I am using my old Staked Address to sign a message to add my new bech32address, which will become my new main one.

Link to old staked Address Verification.
https://bitcointalk.org/index.php?topic=996318.msg51838443#msg51838443

My new Address will be: bc1qd7rqlrw5h4q3g2x45xacd72zshcm2dht2ztclh
-----BEGIN SIGNATURE-----

-----END BITCOIN SIGNED MESSAGE-----

For added security, I also verified the new address:

Code:

What is the point of signing a NEW address without proof of ownership of the OLD address?

There might have two cases for signing with a new address without proofing the sign of old address. 1. the owner of the address lost access of old address/private key. Didn't know that need to proof by his/her old address first.

Sorry to nitpick, but I think the whole point of this thread is securing the ownership of a bitcoin address. What is the point of signing a NEW address without proof of ownership of the OLD address?

You may not want to sign a message from your old address. That's okay, but if you ever need to prove you're the owner you'll have to sign from the old one. You could do what you say if you want to get rid of the old address as a proof of ownership.

[odolvlobo]

Sorry to nitpick, but I think the whole point of this thread is securing the ownership of a bitcoin address.

Here is my understanding:

The point of posting an address is to give you the ability to use that address later to prove that you were the owner of the account at the time that the address was posted.

Posting a address does not prove that the account holder controls the address, but that may be a reasonable assumption if a signed message stating that fact is posted.

Quoting the post helps to ensure that any subsequent change to the post can be detected.

Signing a message has a minor benefit. It allows the address owner to make a statement (but note that the statement can be false). Typically, the address owner asserts that they control the account and that a signed message is sufficient proof of ownership of the account. It is assumed that the account holder would not post the signed message if they did not accept it.

In short, the user should post this signed message and it needs to be quoted:

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
Today is <date>.
I control the account with the user name, <user name>.
Signing a message with private key for the bitcoin address, <bitcoin address>, is sufficient proof of my identity with respect to this account.
-----BEGIN SIGNATURE-----
<bitcoin address>
<signature>
-----END BITCOIN SIGNED MESSAGE-----

What is the point of signing a NEW address without proof of ownership of the OLD address?

I think we should do like this: ...

In posting a signed message containing the new address, the current account holder proves that they are the original account holder and presumably states that a message signed with the new address is also sufficient proof. This effectively makes messages signed with the new address as good as messages signed with the old address.

Posting a new address not signed with the old address gives the current account holder a way to later prove that they owned the account, but it does not prove that they are the original account holder.

I think your suggestion is good, but I would do it more like this because it is more secure. Note that the message signed with the new address is contained in the first signed message. This prevents anyone, including mods and hackers, from substituting a different new address. On the other hand, if the new address is signed with both addresses separately like you did, I suppose that works just as well.

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
Today is <date>.
I control the account with the user name, <user name>.
Signing a message with the private key for the bitcoin address, <new bitcoin address>, is now also sufficient proof of my identity with respect to this account.

- -----BEGIN BITCOIN SIGNED MESSAGE-----
Today is <date>.
I control the account with the user name, <user name>.
Signing a message with the private key for the bitcoin address, <new bitcoin address>, is sufficient proof of my identity with respect to this account.
- -----BEGIN SIGNATURE-----
<new bitcoin address>
<signature>
- -----END BITCOIN SIGNED MESSAGE-----

-----BEGIN SIGNATURE-----
<old bitcoin address>
<signature>
-----END BITCOIN SIGNED MESSAGE-----

Edit: nested signatures work if the signing software modifies markers of the interior message as above.

You may not want to sign a message from your old address. That's okay, but if you ever need to prove you're the owner you'll have to sign from the old one. You could do what you say if you want to get rid of the old address as a proof of ownership.

What if my account gets hacked and the new owner stack a new address?  
fillippone_hacked signs the old address.
fillippone the new one.

Would the situation be sorted with: the old address always wins?

What if the old address gets compromised after I sign a new message?

It's complicated...but signing a new address without having proof of ownership of the old one is a weak practice, in my humble opinion.



EDIT: @odolvlobo posted a great suggestion of nested addresses while I was posting it. Wondering the technical feasibility of nested signature.
EDIT2: @odolvlobo is that a typo? two  <new bitcoin address> in the signed message? One of them should be the  <old bitcoin address>, you might want to check it, I will eventually delete this edit.
