Stake your Bitcoin address here

I don't have private key to my btc address but i have access to my old eth address, so i signed massage from my eth address.

Not quoted since you just got banned for plagiarism.

I don't mind doing it - it's a matter of "public" record given at least one site [LINK] has already archived it:  ^{(given my post will also be archived on that site, I haven't taken the liberty of archiving your post...)}

Quoted and verified with Bitcoin Core. Note that it's better to add the date to the signed message.

Ahh good point. Should I update it or is it to late now?

You should never "update" a post in this thread ^{(or the PGP thread that performs a similar task for that matter)} rather, just post a new post containing today's date along with the pertinent details that you provided earlier.

Thanks.

You should never "update" a post in this thread ^{(or the PGP thread that performs a similar task for that matter)} rather, just post a new post containing today's date along with the pertinent details that you provided earlier.

But why that?

I think there's some sort of misunderstanding about the purpose of this thread. Each person essentially signs the ownership of their account. The whole point of quoting the posts is that even if someone compromised their account and changed the message, everybody could confirm the suspiciousness.

In the example above, I don't find a reason to not update the post. Why to fill the thread with two messages while one of them would be completely useless?

[LoyceV]

In the example above, I don't find a reason to not update the post.

It's not really needed to add the date when claiming first ownership of an address. That's mainly useful to prove ownership later on, to ensure the message is fresh (and can't be reused later).

I think you made a mistake in your signature with the old address.  The message you posted above does not verify, but this one does:

It appears that when you signed the message you left out the second line with your new address.

The signature with the new address verifies just fine:

The message you signed doesn't say anything except that your user name is Charles-Tim and the date is August 10, 2021 You already signed a message before saying the same thing, so what good is the new message, other than to say that your user name is still Charles-Tim?

Think about it. What do you want to say? I think you want to say,

Code:

This is Charles-Tim. My new signing address is bc1qxg4yj92wnq3lcw0kgj8s3l9xx9jhp4f463gxpu. It is August 10, 2021.

If you sign that message, then people will know without a doubt that a message signed with the new address is from you. If you don't sign that message then there is no way to be certain.

Sorry for being pedantic. You have made the same mistake as Charles-Tim. You have signed a message with only your user name and a date, and that is not helpful. If you want to change you signing address, you should sign a message saying exactly that. Otherwise, people in the future can't be certain that you really changed your signing address because everything outside of a signed message can be faked.

Think about what you are trying to do.

Marvell1 wrote a message 4 years ago saying that their signing address is 1NNSoJsWABSiqftBVWze6HUFRFtaBkZy4G. Now, a person claiming to be Marvell1 is saying that they want to use another address for signing.

How does someone know that Marvell1 truly wants to use a new address? Marvell1 signs a message saying that they want to use the new signing address. Without a signature, the message can be changed.

How does someone know that the person changing the address is the true Marvell1? The message is signed with the original signing address. Presumably, only the true Marvell1 can sign using that address.

In short,

Code:

On the other hand, what you have done (sign messages with both addresses) is sufficient in practical terms because while someone hacking your account can replace or delete your messages, they can't replace or delete those messages quoting yours. But, if you are going to do it, you might as well do it correctly.

[Charles-Tim]

You have made the same mistake as Charles-Tim. You have signed a message with only your user name and a date, and that is not helpful.

I am commenting on my behave. I signed an old address with the the present date while also signed a new address, both are verified. I still do not understand what you meant once the old address that was newly signed has already indicated that I am the one that signed the new address.

Signing a message with your name and date doesn't prove that the original Charles-Tim wants to use the new address.

Suppose someone hacked your account and changed the message to the following. Now, I agree that someone quoting your post provides some proof that is probably sufficient for most, but it is not a cryptographic proof and so there may be additional vulnerabilities. If you simply sign a message with your old address saying that you want to start signing with a new address, that solves everything.

[BlackHatCoiner]

I think that what odolvlobo says isn't necessary. Essentially, he told you to include your old address in the message that is signed from your new address.

When you sign a message using an address and decide to post it in this thread, your address becomes a part of your identity. If someone wants to prove that is you, has to provide a signature along with a message that hasn't been signed again. In the case of you wanting to change your address, you'll have to provide a proof that you're indeed you. Including your new address would be optional, because in both cases it'd be enough for us to acknowledge that the proven owner of the old address who also own the account wants to change his identity address.

That's why I find it unnecessary.

[odolvlobo]

I think that what odolvlobo says isn't necessary. Essentially, he told you to include your old address in the message that is signed from your new address.

No, I am saying to do this:

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
I am <user name>. Today is <today's date>. My new signing address is <NEW signing address>.
-----BEGIN SIGNATURE-----
<OLD signing address>
<signature using OLD address>
-----END BITCOIN SIGNED MESSAGE-----

This proves without a doubt that the original <user-name> want to use the new signing address.

As I wrote above, signing messages with today's date using both addresses is probably sufficient assuming the post is quoted, but it is not a cryptographic proof, and it is actually more work than what I propose.

Actually, if you feel that simply quoting a post is sufficient protection against changes, then this is sufficient:

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
I am <user name>. Today is <today's date>.
-----BEGIN SIGNATURE-----
<OLD signing address>
<signature using OLD address>
-----END BITCOIN SIGNED MESSAGE-----

My new address is <NEW signing address>

But, note that simply moving the new address inside the signed message provides so much more protection.

[BlackHatCoiner]

Why should you sign from both addresses? The new address is posted by the conviction that you'll need it to provide a proof of your identity in the future. You should only do the following if you've never posted in this thread above:

Code:

<address>

And this, if you have:

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
I am <user name>. Today is <today's date>. My new signing address is <NEW signing address>.
-----BEGIN SIGNATURE-----
<OLD signing address>
<signature using OLD address>
-----END BITCOIN SIGNED MESSAGE-----
