Title: 2nd page - How to sign a message?! Post by: Z_MBFM on June 18, 2023, 03:17:16 AM Quote Note – i have just correction Broken image .i am not orginal owner of this tutorial. all cradit only for shorena .this guy is inactive for a month thats why i create this topic with fix broken fucking imgur image. and use to host image by talkimg.com. and i have sign a message for my bitcoin address on the first stape and copy all of from shorena Main topic - https://bitcointalk.org/index.php?topic=990345.0 Welcome 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 (https://bitcointalk.org/index.php?topic=357124.msg3847995#msg3847995) for an edited post. I changed it today. Here (https://talkimg.com/images/2023/06/18/HS5X1.png) is a picture. Here is mine. Stake My Bitcoin Address Address Code: 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. Code: -----BEGIN BITCOIN SIGNED 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=996318.0 Someone 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. Index:
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: https://talkimg.com/images/2023/06/18/HS9cW.png and for everyone else reading, it looks like this: Code: -----BEGIN BITCOIN SIGNED MESSAGE----- I added an example how to post the signed message for the blockchain.info part here (#post_bci). Dos and Don'ts: return to index (#post_index)
You think something is missing here? Leave a reply below. Pay to script hash (P2SH) addresses: return to index (#post_index) There 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.

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.

Its a throwaway wallet, but I tend to remove stuff like this. link to picture -> https://talkimg.com/images/2023/06/18/HSKpv.png https://talkimg.com/images/2023/06/18/HSKpv.png Blockchain.info v2 2016.05.11 return to index (#post_index) Update (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 -> https://bitcointalk.org/index.php?topic=990345.msg18991565#msg18991565 Update (2016.5.11): It is now possible to sign messages with imported private keys. Th0ur007 wrote a step by step here -> https://bitcointalk.org/index.php?topic=1467458 Note: 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.

Just one feedback though, can you resize the image? just add the width=x height=x Like this one, https://talkimg.com/images/2023/06/18/HS7zm.png It can be resized to look like this, at least the images will load quick, just saying. https://talkimg.com/images/2023/06/18/HS7zm.png Title: Re: 2nd page - How to sign a message?!

Post by: airbin on July 09, 2023, 05:23:33 PM Learning to sign a message is important but it is not relevant until they are needed, perhaps in the case of the forum it is necessary. But I think that learning to verify wallet signatures is perhaps relevant to comment in your OP's intro, another topic, but if you mention thing as for the campaigns, you are centralizing it, the context, that is, It's not always all about the forum.

You didn't read the first part about OP saying that he/she is not the owner where OP only reposted the topic with the images that are now visible because images uploaded on imgur are no longer displayed. In order to make it display again is that OP used different host image such as talkimg and other similar websites. My guess why OP reposted this could be the thread of OgNasty where he rewards merit when you sign a message correctly and by the way, the thread is now locked but OgNasty created a new thread that is now self-moderated thread for a reason and I think it is helpful because some forum members abused OgNasty's generosity by applying alt accounts or whatever they can think of just to get merited.<......> It is now locked (the old one) because OgNasty created a new thread that is self-moderatedThis is the new one https://bitcointalk.org/index.php?topic=5300698.0 Title: Re: 2nd page - How to sign a message?!
