So is section (1.3)
Finally, something explains in clear terms what an isomorphism is.
Quote from: http://cr.yp.to/bib/1987/lenstra-fiec.pdf
(1.3) Isomorphisms and automorphisms. Let E = Ea,b and E'a',b' be elliptic curves over K. An isomorphism E → E' (over K) is defined to be an element u ∈ K* for which a' = u4a and b' = u6b.
So taking this in secp256k1's perspective, a=0 and b=7. So any curve that manipulates b is potentially an isomorphism of secp256k1 since a=0 implies any curve can satisfy the corresponding relation above.
So this means, b=26*7, 36*7, 46*7 ... are all isomorphisms which also means there's an infinite number of secp256k1 isomorphisms we can calculate (of course that would not be efficient though) and we're not stuck with just the six from VanitySearch.
The very last paragraph is interesting.

Great job, so looks like these factoring methods really were designed to work on privkey factors as well. So it's a repeated Pollard's rho - 1 in a loop, followed by that algorithm on the right (the curve membership test) if that fails I guess? I suspect the elliptic curve used in the example will also have to be changed to y^2 - x^3 - (or maybe +) 7, right? Since secp256k1 doesn't have the "ax" factor, I'm not sure where "a" is going to be placed to make the algorithm usable.
Friends! Why are you all doing hopeless brute-force? Does anyone know other algorithms? Maybe -lenstra_elliptic_curve_method, quadratic_sieve?
Those are both integer factorization algorithms so won't work against secp256k1 elliptic curves. Pollard Rho, Pohlig-Hellman (though slower than the rest), distinguished points and BSGS are the way to go.
This paper rounds up most of the known algorithms: https://math.mit.edu/classes/18.783/2017/LectureNotes10.pdf
There don't appear to by any public, more recent & novel methods for calculating descrete log on Google Scholar.

that might be because not everyone is using it as a means for research - some are specifically using it to target addresses in the hope/attempt to steal the funds.
Yes exactly! What's the point in research?What will research give me? I never had bitcoins, when I had the opportunity to buy BTC for 1-100$, I did not know about it, I found out about bitcoins only in 2017, when video cards were becoming more expensive.
If that's what you're trying to do, then you are wasting your time trying to find a match in such a large keyspace.
GPUs can only search up to around 2^40 keyspace in a reasonable time (depending on how many GPUs and the kind you use, it could be even less) while bitcoin private keys exist in 2^256 keyspace. That means that unless someone deliberately posts a small range of the private key you can search in, it will take much, much longer than the human lifetime to exhaust bitcoin's entire keyspace to find some private keys.
Brute forcing has always been this hard, it doesn't become difficult as bitcoin's price goes up (and for the same reason, bitcoin GPU mining has been unprofitable since 2013 or so).
Uninitiated crackers will actually spend more on the hardware itself than the potential reward if they are not careful to buy bargain hardware, not to mention electricity bills. Privkey cracking is about to become a specialized industry, like bitcoin mining.
I agree - doesnt stop some of them from trying.
I am currently able to process 2^54.75 Keys/second using a program I've been writing that combines the best of Bitcrack with BSGS using GPU's, at the moment im only capable of getting these speeds while searching public keys, while searching public address compressed Im still getting about 2^38.127 Keys/second. I will be discussing this program more and maybe releasing a copy for public use after I find the 64 address!

Before buying a 2080, I was very hopeful that I would definitely find something. But after 2 weeks of using the 2080ti, my results file is empty and I'm depressed. The only thing is that I have lowered the card consumption by 65% for less wear and now I have 1250mkey instead of 1500.
Before that I had a 660ti card - 80 mkey

You should know that methods to crack 256-bit bitcoin private keys are primarily for research purposes and it's almost impossible to find a key to an unsolved puzzle transaction using a small group of GPUs.
