Private Key doesn't match to bitcoin address
by
harvysam
on 20/03/2018, 10:47:35 UTC
I had been using BTC for a while now and I used to use Bitcoin Core in my system for all transactions, recently I had a problem with my computer and now I just thought let me use blockchain.info website.
But the private key which I had for my address in bitcoin core shows a different address in blockchain and I'm not able to see my balance.

Could anyone help or suggest me on this?

@pebwindkraft, thank you for clearing my doubt, it was really helpful.
I'll surely drop in a mail to Sean Bradley on this.

also I am looking at 2coin.org, but can not see all witness data:

Code:
"vin": [
    {
      "txid": "880c7b67bfb6d70edaa74292edcd1b3585b91890762eafe123799f6d6599a1eb",
      "vout": 1,
      "scriptSig": {
        "asm": "002065d416c48a8072e0ac51c2d111eb194f009caef0332446c1bf2097316cf07fa9",
        "hex": "22002065d416c48a8072e0ac51c2d111eb194f009caef0332446c1bf2097316cf07fa9"
      },
      "sequence": 4294967295,
      "n": 0,
      "addr": "3422VtS7UtCvXYxoXMVp6eZupR252z85oC",
      "valueSat": 112485041,
      "value": 1.12485041,
      "doubleSpentTxID": null,
      "sigR": "16c48a8072e0ac51c2d111eb194f009caef0332446c1bf2097316cf07fa9ffffffff",
      "sigS": "",
      "sigZ": "7f9dad303b47a86e29a4e362b0e9aaa878ce708c41fe451401fda8e5d6a33800"
    }
  ]

Just wondering if things are not yet fully (segwit-) developed?  I do not understand were the sigR value comes from. Do you have more examples?



Exactly is what I've seen in this site.
Now, in this site if you look at all the outgoing transactions of this address "3422VtS7UtCvXYxoXMVp6eZupR252z85oC" it show's the same SIG R: "16c48a8072e0ac51c2d111eb194f009caef0332446c1bf2097316cf07fa9ffffffff",

After looking at few articles about segwit that is when a question raised in me about the 2coin.org website that it could be not developed for SEGWIT.

if you could show the tx ID, it would be interesting to analyze it ...


Here is the TX ID of the repeated R.

Also, I'm a bit confused here, I believe this is not the actual Signature R, as I had looked thru so many articles in this forum that the P2SH-P2WPKH transaction works in a bit different way but the 2.coin.org gives some value as Signature R which is repeated in all these transactions and no values in Signature S but without the Signature S it is showing Signature Z.

I'm not sure if this is the right section to ask this question.
I recently noticed a transaction with almost every transaction having the same "Signature R", this address belongs to segwit address.
But the strange part I notice for the same is there is no "Signature S", I actually used the Sean-Bradley's 2coin.org site to find details of the transactions.

Should the P2WSH transaction be without "Signature S"? Or, is it getting stored elsewhere??

What do you mean by "original curve point"? Do you mean the generator point? If so, that's part of the curve parameters. You can only know that by knowing what curve you are using and its parameters. Given just a public key, you cannot know the curve parameters.

Using Elliptic Curve of SECP256K1 of bitcoin, I believe with scalar multiplication of "Point P & Q" we get the "point R", but the value what we get is hash values but I can convert it to the integer which results in "77 digits in X and Y coordinate".

I'm trying to learn something that usually in a graph we don't work on large integers, but is there a way to remove the "generator point hash G" so we can see the actual point values like [0,1] or [10,16] etc.,??

Elliptic curve point of R

I've the Public key which is
0x04 32 bytes X coordinate 32 bytes Y coordinate.
Is there a way we can get the original point value on the Elliptic curve of R?

I did convert the 32 bytes into integer and I believe the curve point is generated using the order of the base point, now can we remove the order of the base point and look at only the values on the curve?
