Main topic -
https://bitcointalk.org/index.php?topic=990345.0Welcome to the world of bitcoin.
I have still Newbie like you, looking for scrap, asking questions, working faucets. Faucets are a waste of time. Yes, it was a bit easier in the past. I could join a signature campaign with only 39 posts. Spammers have ruined this pretty much for Newbies though and if they continue I am afraid they will ruin it for all of us. This is not the topic though, sorry for the distraction. You dont believe me that I joined a campaign as Newbie? Well I can proof it to you and I can show you how. By signing a message.
The post quoted below was written by shorena. It was not edited and it contains a bitcoin address. If you click on its link you will see that it has no dotted line below the time and date. See
here for an edited post. I changed it today.
Here is a picture.
Here is mine. Stake My Bitcoin Address
Address
bc1qnfqesqmph352h29ulys4tzapg6ljv6rhxj77jt
And I can sign a message with this address to prove that I still have access to the private key that belongs to this address.
-----BEGIN BITCOIN SIGNED MESSAGE-----
This is Z_MBFM from bitcointalk.org and today is 2023.06.18 and i am sign this message

You are probably not impressed. So what, a signed message, you might think, but its very important here if you want to trade with someone. There are currently at least 3 accounts in the meta section that are contested. The main problem with all of them is: someone was unable to sign a message, someone did not request a signed message for a trade or someone has no idea how to sign a message. I will try my very best to show you how to sign a message and how to verify a signed message. For this I will use pictures as I know not everyone here speaks english. I will also update this thread over time.
If you want to get your address witnessed somewhere for the future, use this thread by Tomatocage ->
https://bitcointalk.org/index.php?topic=996318.0Someone will quote your post there to make sure a hacker that has control over your account can not change it. Make sure you only post addresses you can sign a message with. You can use this thread to test signing message, I will verify them all and Im sure other users will chime in when I am not online as well.
If you want to
thank me because this thread has helped you,
post a signed message. If you just tell me it helped you, Ill probably think you never even bothered to read this.

Format:Note: Always
include the date and reason when creating a message. If you sign a generic message it could be reused by someone else.
When you sign a message you want to present it to someone else and they want to verify the message. In order to make this extra easy its important to use a certain format. You can modify it as needed, but there are certain things to keep in mind.
Every symbol is important. The symbols
> and
< in my examples have to be removed. When you sign a message and somewhere have two spaces between two words, both are important for the signature. Thats the whole point of a signature. It detects whether someone changed the message or not. The board here has a "code" environment thats perfect for this. It will make sure no linebreaks are added and the other person can easily copy it. I used the same format above.
If you write a post/PM it should look like on the picture below:
and for everyone else reading, it looks like this:
-----BEGIN BITCOIN SIGNED MESSAGE-----
<insert message here>
-----BEGIN SIGNATURE-----
<insert address here>
<insert signature here>
-----END BITCOIN SIGNED MESSAGE-----
I added an example how to post the signed message for the blockchain.info part
here.
Dos and Don'ts:return to index- DO include the current date. This ensures the signature can not be reused on a different day.
- DO include the reason and be specific. This ensures the signature can not be resued for a different reason.
- DO include your nickname and where you use it. This ensures the signature can not be reused, e.g. by Shorena on AcmeCorpTalk.
- DO NOT use a compromised machine (virus, keylogger, etc.) to create a signature. Signing unlocks your wallets protection the same way spending bitcoin does.
- DO NOT upload your private key somewhere in order to create a signature.
- DO NOT give your private key to someone else in order to create a signature for you.

Pay to script hash (P2SH) addresses:return to indexThere is no way for pay to script hash addresses without private key (yes, they are possible) to sign a message. For multi-sig-addresses (a subset of P2SH addresses) there are private keys, but there is no consistent definition on how a signature for a message would be verified. Thus,
its impossible to sign a message with an address starting with a 3 in a realiable way. With the addition of P2SH-P2WPKH addresses (SegWit, but starting with a 3) this did not change. At least it did not in bitcoin core, other wallets may still allow signing or verification.

Blockchain.inforeturn to indexNote: Blockchain.info is an online wallet, thus their interface could change. Since there is no version number to indicate a change I added the date. I used the stock Tor browser for this (see the URL), but its identical to the regular version. The black bar masks the wallet identifier. Its a throwaway wallet, but I tend to remove stuff like this.

Blockchain.info v2 2016.05.11return to indexUpdate (2017.5.13): According to user apoorvlathey it is now possible to sign messages with the new version as it was in the past. User sHeRiLyN1618 reports that this is only possible for imported addresses, but not addresses generated with the service. For more information read the posts starting from here ->

Th0ur007 wrote a step by step here ->
https://bitcointalk.org/index.php?topic=1467458Note: Blockchain.info's new wallet does not allow you to sign a message, nor does it allow you to easily export the private key in order to sign with a different wallet. There is a crude work around here ->
