Big Thank All of You !!! You get me axact information what I search.

So now it's your turn, what is your ultimate goal with this/these public keys? I'm sure it's not just so you can fire up some software...

if you check his post history and what topic he has been super active in you can probably guess why he is looking for "public key" specifically! hint ECDLP Wink

Doesn't really matter, does it... I couldn't care less if the OP found a piece of software that promised him he could reverse engineer a private key starting from a public key.
Some people just need to learn the hard way, if he tries to reverse engineer a private key all he'll do is infect his pc with malware and/or waste a lot of his time... Doesn't have any impact on me either way

If he's just trying to learn, kudos to him... I can only encourage people that want to broaden their knowledge.

My software input parametr only pubkey accepted. So, I need a pubkey for adress

So what software is that? Your 1337 pubkey to private key extractor?

Privkey for bc1 and the pubkey will be the same or different ?

I strongly suggest you try to learn a bit more on the internal workings of bitcoin, that way you might also realize you won't get rich by trying to "hack" private keys.

That being said: An address is just a form of encoding a public key (or the hash of the public key). Bitcoin works with a combination of Private Key - Public Key pairs. So the same private key can be used to generate segwit addresses as well as legacy addresses.

Different... The private key will always be different from the pubkey... otherwise it wouldn't be called private key vs public key

Bro how you get pubkey for bc1 ? I very need it. Explain please how to get pubkey for bc1 ?

Can you please read the answers already given?

That's a very broken website IMO, it's full of dead links at my end.

For your question, you wont be able to find the public key unless you own the address (you have the priv key)
or it was used to send bitcoins at least one time.

If it was used before and it's a P2WPKH or a P2WPKH-in-P2SH, simply paste it in a blockexplorer: use blockstream.info to follow this:
Click a transaction that used it as an input.
Click "Details +" and Find "Witness" inside that particular input.
The 33Byte string (66 characters) after the last space is that SegWit address' public key.

To sum up:

The segwit address has to be used as an input in a transaction, if not then the public key is not known in the blockchain.
So you need to find a transaction where the segwit address is used as an input. Any blockexplorer should be able to help you with this
Once you have a transaction id either use @nc50lc description I linked above to get the pubkey
Or you could use bitcoin cores bitcoin-cli to decode a transaction as described by @mocacinno

But the real question remains: why do you need these public keys??. I have an idea though...

Bro, as I right understand this is pubkey:

"txinwitness": [
   "30440220476ef5c395dd30dacac4c5476cc7c6d258de9c8e7581c26304f27dded4e810f50220100 163a5f440f01442ec1eaafece26e43a54d11ab1d686fd3bae22ae3c1e66db01",

   "sequence": 4294967295

But - this is 2 legit pubkey for 2 btc adresses Huh

? What pubkey is need to use ?

Or are you talking about the fact that you see 3 unique signatures and 2 unique public keys? That's because this transaction uses 1 unspent output funding the address you're investigating, and 2 unspent outpust from a different address (most likely both addresses belong to the same wallet).

--snip--

Bro, and how to fined exact pubkey ? I was found pubkey in this raw transaction, but I was know pubkey and use search/ How many bytes I need sheft fo start of raw transaction, or enother method get pubkey from raw transaction. Explain this more datailed please Huh

If you have bitcoin core installed locally (or on a server you can access), you can just do
bitcoin-cli decoderawtransaction [rawtx]

You'll see the unspent outputs being used as an input to your transaction (vin), and you'll see the pubkey straight away...

If you don't have bitcoin core, just use google and search for something like "decode raw bitcoin transaction online"... There are tons of tools to help you do exactly this...

Code:

bitcoin-cli decoderawtransaction 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

cool. https://www.indicrypto.com show what adress for this pubkey is 12f63XH2x5P88TKNdhSMcw9NjteuSr1anq

Probably because they haven't updated their code since segwit...

and indicrypto cant fined pubkey for this adress, i think becouse no transction !

yup... If you haven't spent any unspent outputs funding a certain address, the public key has not yet been broadcasted...

Bro how you get pubkey for bc1 ? I very need it. Explain please how to get pubkey for bc1 ?

There are many ways, but you can just use a blockexplorer if you want to... Or you can fetch the raw, signed transaction spending unspent outputs funding the address and decode said transaction...
