i just play around with math, by using simple decimal multiplications combined with logarithmic insights, you can systematically determine key values within a numerical range.

fun fact the unique thing is that the key is indeed located right in the area that has been measured using mathematics, I am using 2 pieces of evidence for now.

for now i'm just doing this thing work, thanks for read and respect my post about puzzle.

But that has nothing to do with puzzles. He needed a privkey (recalculated divided whatever) to get the private key. What is the point.  Lips sealed

Hello everyone,

I need to show you something I was working on for a few months and because I am actually addicted of this, you have to see it.

So basically the case is I want to verify If I am that "smart" or it is just pure coincidence.

I have just now registered first ever account.

I am working with a very interesting python script that basically get's the private key directly from the hash160 of basically any address up to puzzle 130...sounds crazy isn't it?

So basically what I need to decode private key of the hash160 of an p2pkh bitcoin address? hah a private key Wink

Seriously..

1.Chose whatever range, like I said, for the moment I have tested until puzzle 130, generate Yourself a hex private key in between chosen range and get the compressed address.
2 Convert the hash160 of that address to decimal string.
3.Convert the hexadecimal private key to decimal as well,
4 Now using a big integer calculator for example http://www.javascripter.net/math/calculators/100digitbigintcalculator.htm ( I am also using it ) divide the decimal string of hash160 by decimal version of private key
5.The resulting string now You have to multiply times decimal private key.
6 That multiplication will result with a long string of course but quite similar with the first digits like so basically that string will be required by me.

That is pretty obvious that having only hash160 string we cannot see the private key directly can we?
 
So what I need actually to decode private key then?

I need a hex range boundary of Your address choice and the the resulting decimal string from step 6. or as You want convert it to an address back using brainwallet converter, so range boundary and an compressed address Wink

Time to get the private key? Instant, 0.1 sec.

The most important: I don't need a private key Smiley, I will get one to verify what I say and second read carefully so You have zero questions about the steps.

Don't forget to pick up the range and address with that private key You don't use personally, that is just a test. Wanna see the results reply with what I ask for.


When I have the private key I will reply with signed message so You can verify Yourself.

I guarantee you will be intrigued.

this guy nailed it

Now we can officially transition to #67.

Let me fix that graph for you

Before judging, note that all your % and etc. are inside the red line and even if it weren't it would need a very high amount of zoom-in in to actually be noticeable.

okay bro, thankyou for sharing your thoughts.

Thanks for explaining it but i dont get what is the number 95823  from your first line

Code:
old_key = 4563 -- was from "95823/21"
[/quote]

95823 was from 1764F on 17 bit puzzle, 17 bit into 21 bit.

"How many multiples are there from 95823 to 2097151?"

95823/2097151 = 21 = 4563.

Calculate the far distance when the decimal is multiplied by 1.05

1811511 * 1.05 = 1902086.55 (depends on your settings).

1902086.55 results are rounded to 1902087

so the search is 1811511 to 1902087

How do you determine the exact range to multiply by 1.05 in a puzzle that does not have a solved private key?

it's simple, if you do multipler with large value, it's gonna be exceed, 1.01 - 1.05 it's quietly large.

I'm fully convinced that with math and databases the public key range can be reduced, so I'm not surprised that it was solved. Whoever did it simply reduced the range enough to a manageable level for their computing power.
I don't think there is a backdoor in secp256k1, but rather shortcuts for insecure private keys.

this!

@Tepan

Can you explain a little bit more your formula ?


First thing first it's funny someone really spend their time to this like Mr.AKITO.

I want to explain but I'm afraid of appearing smarter than my friends who are great at spending their time creating and ensuring programs like search using the hash of public key 160 and even compressed public keys, will feel offensive to them, this is just my thoughts for 2 years paying more attention to this forum and puzzle.

but okay if you want to.


old_key = 4563 -- was from "95823/21" 21 is divided by count the 95823 into 2097151, have 2 option 22 or 21, 21 is precisely with target.
old_range = (65536, 131071)
new_range = (1048576, 2097151)

result :

[1245699, 1660932, 2076165, 1400841, 1816074, 1140750, 1555983, 1971216, 1295892, 1711125, 1451034, 1866267, 1190943, 1606176, 2021409, 1346085, 1761318, 1085994, 1501227, 1916460, 1241136, 1656369, 2071602, 1396278, 1811511, 1136187, 1551420, 1966653, 1291329, 1706562, 1446471, 1861704, 1186380, 1601613, 2016846, 1341522, 1756755, 1081431, 1496664, 1911897, 1236573, 1651806, 2067039, 1391715, 1806948, 1131624, 1546857, 1962090, 1286766, 1701999, 1441908, 1857141, 1181817, 1597050, 2012283, 1336959, 1752192, 1076868, 1492101, 1907334, 1232010, 1647243, 2062476, 1387152, 1802385, 1127061, 1542294, 1957527, 1282203, 1697436, 1437345, 1852578, 1177254, 1592487, 2007720, 1332396, 1747629, 1072305, 1487538, 1902771, 1227447, 1642680, 2057913, 1382589, 1797822, 1122498, 1537731, 1952964, 1277640, 1692873, 1432782, 1848015, 1172691, 1587924, 2003157, 1327833, 1743066, 1067742, 1482975, 1898208, 1222884, 1638117, 2053350, 1378026, 1793259, 1117935, 1533168, 1948401, 1273077, 1688310, 1428219, 1843452, 1168128, 1583361, 1998594, 1323270, 1738503, 1063179, 1478412, 1893645, 1218321, 1633554, 2048787, 1373463, 1788696, 1113372, 1528605, 1943838, 1268514, 1683747, 1423656, 1838889, 1163565, 1578798, 1994031, 1318707, 1733940, 1058616, 1473849, 1889082, 1213758, 1628991, 2044224, 1368900, 1784133, 1108809, 1524042, 1939275, 1263951, 1679184, 2094417, 1419093, 1834326, 1159002, 1574235, 1989468, 1314144, 1729377, 1054053, 1469286, 1884519, 1209195, 1624428, 2039661, 1364337, 1779570, 1104246, 1519479, 1934712, 1259388, 1674621, 2089854, 1414530, 1829763, 1154439, 1569672, 1984905, 1309581, 1724814, 1049490, 1464723, 1879956, 1204632, 1619865, 2035098, 1359774, 1775007, 1099683, 1514916, 1930149, 1254825, 1670058, 2085291, 1409967, 1825200, 1149876, 1565109, 1980342, 1305018, 1720251, 1460160, 1875393, 1200069, 1615302, 2030535, 1355211, 1770444, 1095120, 1510353, 1925586, 1250262, 1665495, 2080728, 1405404, 1820637, 1145313, 1560546, 1975779, 1300455, 1715688, 1455597, 1870830, 1195506, 1610739, 2025972, 1350648, 1765881, 2097151, 1090557, 1505790, 1921023]
