Stake your Bitcoin address here

[albert0bsd]

Bitcoin Core still can't sign a message from a Segwit address. As far as I know, Electrum made-up their own "standard" for signing.

Well, I really don't know why the signatures of a Segwit addreses is not yet an Standard

I want to try to make an example of something curious, a signature that is valid for both address P2PKH (Legacy) and P2WPKH (Segwit)

I am going to use my staked address here:

address

Code:

bc1qjyhcjacmpc9pg8wes82lktyrjcwk4sdvqtm7ky

message

Code:

albert0bsd from bitcointalk.org 27 Sep, 2023

signature

Code:

KA55lRDVVcmNzydSdLsknjq2QS/CFW0utVGhtfmr3iirPW/zGoviBY7n7lE72nH81SV+D2a5syJpb2OZ/NUzdns=

The public key of that wallet is

Code:

02b96b69d11f50e029da620d879a1ddf0d759123b23364a5384cfd815fbb183e79

The RMD160 Hash for that public key is 912f89771b0e0a141dd981d5fb2c83961d6ac1ac

So in this page we can calculate the address https://learnmeabitcoin.com/technical/script/p2pkh/



The P2PKH address for that public key 1EEfvk3usipJwrvekE12cESXWDrCZWgv3S

You also can calculate the Segwit address on this page: https://learnmeabitcoin.com/technical/script/p2wpkh/



Now the signatures, if you make a signature that is valid for Legacy addresses ( Compressed P2PKH)

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
albert0bsd from bitcointalk.org December 2, 2024
-----BEGIN BITCOIN SIGNATURE-----
1EEfvk3usipJwrvekE12cESXWDrCZWgv3S
IAyi+i9eayGP1PTxgd6HI9FNjbPswZRwxn87fe6tSuyYbrPmkW/qirDEYGN4NlzpP+8SI2xrL7YINzmQvaeKEGU=
-----END BITCOIN SIGNATURE-----

Now please look a at the signature

Code:

IAyi+i9eayGP1PTxgd6HI9FNjbPswZRwxn87fe6tSuyYbrPmkW/qirDEYGN4NlzpP+8SI2xrL7YINzmQvaeKEGU=

If you replace the address with the Segwit : bc1qjyhcjacmpc9pg8wes82lktyrjcwk4sdvqtm7ky

The same signature data is also valid for the segwith P2WPKH address:


Check by yourself:

address

Code:

bc1qjyhcjacmpc9pg8wes82lktyrjcwk4sdvqtm7ky

message

Code:

albert0bsd from bitcointalk.org December 2, 2024

signature

Code:

IAyi+i9eayGP1PTxgd6HI9FNjbPswZRwxn87fe6tSuyYbrPmkW/qirDEYGN4NlzpP+8SI2xrL7YINzmQvaeKEGU=

Obvious because both address are generated from the same public key.



This usually don't happen in the other way, because the Electrum standard use another encode byte that is not compatible for the Legacy Signature Chekers

[Charles-Tim]

Obvious because both address are generated from the same public key.

Although it is actually because both addresses are generated from the same private key which is required for the signature. The private key generates the public key which still makes you correct, but it is private key that is important about it.

Yes exactly, and that is my whole point, why the signatures for segwit isn't an standard yet, regardless its trivial to extended the current standard to check them, a lot of wallets support it, just the "standard" title is missing.

I know this topic is just to stake address along their signatures. Sorry to divert the topic I just want to point this. Thank you!

[DireWolfM14]

why the signatures for segwit isn't an standard yet,

Because segwit is just a segway to taproot, and will be obsolete soon.  Plus, no matter how much you like signing messages with bitcoin addresses, that's not their primary purpose.  Bitcoin as a message signing tool lacks significant features, and isn't as practical as GPG.  Bitcoin development is focused (as it should be) on reducing block size and transaction fees, not trying to recreate GPG.

[Charles-Tim]

Because segwit is just a segway to taproot, and will be obsolete soon.  Plus, no matter how much you like signing messages with bitcoin addresses, that's not their primary purpose.

You mean segwit version 0 will be obsolete soon? But it is still the most used address and also recommended by some wallets for lowest fee. Even if not recommended, it remain the default. Also what albert0bsd meant is that the message signing is not exactly signing message with bitcoin address but with bitcoin private key which can generate all types of the addresses.

Bitcoin development is focused (as it should be) on reducing block size and transaction fees, not trying to recreate GPG.

You mean increasing block size and reducing transaction fee. For lower transaction fee, segwit version 0 (segwit) is comparable with segwit version 1 (pay-to-taproot). P2TR has lowest consolidation fee and also if the inputs are getting more. But segwit version 0 has the lowest fee if the outputs are more or if the inputs and outputs are the same. The output virtual size for version 0 is lower while the input virtual size for taproot is lower.

The reason we thought taproot was created which will significantly reduce transaction fee is in multisig, by requiring just a single signature for transactions, just like in singlesig wallets, and also having just one public key required in fee as both signature and public key will combine into one for making transaction despite that there are more keys and signature required for the transaction. But as of today, I was unable to see any wallet have that feature. The known multisigs are still legacy what its addresses start from 3 and segwit P2WSH that its addresses start from bc1.

I have to do it too, let's see if I can organize myself
do you use electrum?

I haven't done it yet, not because i am lazy but it makes me very uncomfortable and a little paranoid when using my real wallet
I would like to ask you if there is an alternative that i can install on the phone so as to use a wallet only to sign with an empty address.

thanks to those who answer me

[PX-Z]

I would like to ask you if there is an alternative that i can install on the phone so as to use a wallet only to sign with an empty address.

Yes, you can do it and its the recommended one for this purpose. As long you saved the back up of this wallet too for future use, say your account is hacked and need to sign the wallet address again for verification that you own the address.

Previously, you signed a message associating your account with the address 1JpDBvzAWpbKsfW7iuMchgsgWMSciMzgd7. If you cannot sign a message with that address, we have to assume that you are now a different person.

Here is the previous post: https://bitcointalk.org/index.php?topic=996318.msg30411756#msg30411756

Typically, if you want to use a different address, you post a message signed with the original address saying that you want to revoke the old address and start using the new address.
