Stake your Bitcoin address here

MY NEW ADDRESS:

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
Hi. This is Marvell1. Today August 10 2021
I want to proof my new BTC address: bc1q0h35js5pm2qrnfx3a44jv4funs0fkqqhd3dlq8
-----BEGIN SIGNATURE-----
bc1q0h35js5pm2qrnfx3a44jv4funs0fkqqhd3dlq8

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

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:

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

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.

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.

New address: bc1qt8wzxfq4p2ufpumd6w02p7kdr5c7uaqeekmeje

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
This is Charles-Tim. My Bitcointalk.org newly staked address
-----BEGIN SIGNATURE-----
<signed with bc1qt8wzxfq4p2ufpumd6w02p7kdr5c7uaqeekmeje>
-----END BITCOIN SIGNED MESSAGE-----

Thanks, I have just signed the old address now, I was using Coinomi before, but I want to use Electrum address is the reason for the new address signed up there. I perfectly sign the old address now on Coinomi.

Old address: 3HkmxFukfkRkTV6BR7xRSNxGjyM38qcnaJ

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.

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-----

Sorry, I am editing my posts as you reply. I think we are agreeing. The benefit of signing the first time (and with the new addresses) is that it proves that you actually control those addresses. That might be useful, but it does not prove identity.

The benefit of signing the first time (and with the new addresses) is that it proves that you actually control those addresses. That might be useful, but it does not prove identity.

What's the benefit of knowing that I actually control an address the time I stake it? You have two options.

Option 1: Post an address you own.
Option 2: Post an address you don't own.

Whichever option you choose, you deserve your fate. If you chose option 1, you'll be able to provide a proof of your identity in the future. If you chose option 2, you'll only harm yourself.

It seems that they don't get this since the 20th post.

Another suggestion, I might be wrong though.

If you just put Bitcoin address or PGP key, it is easy to impose another person. A signed message is better.

There might be a good reason to prove that you control an address upfront. I don't know a reason off-hand, but if you are going to stake and address, you might as well take the opportunity to prove that you control it.

Edit: One reason might be if your signing address is used elsewhere and you want to link other identities to your BCT account.

I don't fault them. Signatures and their capabilities are complicated.

I signed the old address with yesterday's date, also I signed new address yesterday, I still do not understand what you mean. I am not implying that you are wrong but neither was I wrong, but your post is highly not necessary. If you think you are correcting me, thank you, I appreciate, but that prove is enough I control the two address. I still have two addresses on this forum that I can sign, but like I commented before, I want to use an address generated on Electrum for the staking which I just did. If I did 1 + 1, and you are commenting that doing 2 is the right one, doing 2 is just an alternative because 1 + 1 = 2 

[TheBeardedBaby]

Staking an address via signing a message has the sole benefit to show the rest of the world that you know how to sign a message with address.
BTW there are people staking addresses with leaked (or available online) private keys for which I don't see the logic behind it.

Looks like you just recently woke up from a long period of inactivity and tried to prove account ownership in the right way. Its good, If possible, you can also sign messages with a new address that will come in handy in the future.

That's not enough... You have to sign a message with it, in order to prove that you have the private key ^{[full control]}.
^{- Just scroll up and follow the proper format [three parts: Message, address, and signature].}
