Today I tested Kangaroo 2.2 on the Ubuntu. Everything works great! Thanks a lot Jean_Luc!
Most of the participants in this discussion are programmers, and I have a question for you. How do you loop the MultiPubKey?
I would really like to search the list using different public keys in one specific range.

For now it only search for 1 key at a time. When the first key is found then it goes to the next one.

Can someone explain the ht max, ht min, ht avg, ht sdev means. Is that like how many times a DP has occurred in the table?
165  Bitcoin / Development & Technical Discussion / Re: Pollard's kangaroo ECDLP solver on: December 31, 2020, 01:18:37 PM
that means that about 1/3 of the all possible values of Y are valid Y coordinates (are coordinates of a point/pub key) and about 1/2 of all the possible values of X are valid X coordinates.

Maybe we can use that as an optimization and go through all the X values, and check that (X2 + 7) mod p gives a cubed number which would imply a valid Y. This would eliminate half of the search space. Similarly we can go through all the Y values and calculate Y3 mod p is a square number which implies a valid X and eliminate 2/3s of the search space.

Since the invalid points derived for each X and Y don't overlap, we have already removed 1/2 * 2/3 = 1/3 of the total possible search space like that.


256/3  128/3  64/3  does sound better than  256/2  128/2  64/2

For the really smart people out there...I had read somewhere that a pubkey may have 2 X coordinates, maybe 3 X coordinates, can't really remember. But as I've been dabbling with Kangaroo program on and off for almost a year now, I know I have found same pub/priv key in same range, with two different tame and wild distances. I have also found keys let's say 12 bit keys, in ranges of upward of 64 bit range. And those were all with the same distinguished points. I wonder if one could find more tame and wild distances/coords by changing the distinguished point value, in the same range.

Anywho, just interesting to find same pub/priv key with different tame and wild distances/coords.


I always wanted to ask what's the probability of different distinguished points to the same pub/priv key.

Ripple is not taking this legal action from the SEC lying down. It has pledged to fight back, even as several exchanges are suspending XRP trading for users....Ripple will get massively fined, SEC will take their XRP tokens, money is gone in this scam and it ends from there. After this SEC XRP WILL become a beast with no mercy. Too much already and 10 billion were lost by investors because of a few people.
168  Alternate cryptocurrencies / Service Discussion (Altcoins) / Coinbase announces it will suspend XRP trading as price drops another 10% on: December 29, 2020, 12:33:38 AM
Coinbase plans to suspend trading for the token on Jan. 19 but added it "may be halted earlier as needed."

Major cryptocurrency exchange Coinbase will suspend trading for XRP in response to the United States Securities and Exchange Commission taking legal action against Ripple.

According to a blog post published today by Coinbase chief legal officer Paul Grewal, the exchange will fully suspend XRP trading starting on Jan. 19 at 10:00 am PST. Coinbase clarified that “trading may be halted earlier as needed” to maintain the exchange’s market health metrics. In addition, the suspension will reportedly not affect Ripple-backed Flare Network's upcoming Spark (FLR) token airdrop.

"The trading suspension will not affect customers' access to XRP wallets which will remain available for deposit and withdraw functionality after the trading suspension,” said Grewal. "We will continue to support XRP on Coinbase Custody and Coinbase Wallet."

The U.S.-based exchange is the largest so far to take a position on XRP following the Dec. 22 announcement that the SEC will charge Ripple, CEO Brad Garlinghouse and co-founder Chris Larsen with conducting an "unregistered, ongoing digital asset securities offering."

Earlier today, crypto exchange OKCoin announced that it will suspend XRP trading and deposits beginning on Jan. 4. Bitstamp stated it will halt XRP trading for U.S. residents, while smaller exchanges including OSL, Beaxy and CrossTower announced they will take similar actions against trading the token.

Some crypto users are anticipating other exchanges falling in line like dominoes to delist or suspend trading of XRP now that a major player like Coinbase has taken a position on the token.

"You will soon see Kraken, Bittrex, Genesis, Grayscale and other members of the Crypto Rating Council delist it too," said Twitter user PratikKala. "Liquidity will dry up and the remaining market makers in Asia will have to exit it too."

Grayscale Investments may have already have distanced itself from XRP. According to Twitter user "ShardiB2," the firm is reportedly ending subscriptions for its XRP Trust by announcing it would no longer accept new subscriptions or process pending ones. The Grayscale website declares that "The Grayscale XRP Trust private placement is currently closed."

Following the Coinbase announcement, the price of XRP immediately dropped more than 10%, falling from $0.28 to $0.25 at the time of publication. This is the latest in a series of bearish movements for the token, the price of which has fallen 44% since the SEC announcement.

Is Ripple worth investing in 2020 and beyond? ... According to the online forecasting service, WalletInvestor.com, XRP is a “bad, high-risk 1-year investment” option. In one year, the price of the coin is expected to fall to $0.02 by December 2020. In five years, they predict this cryptocurrency to trade at $0.029 in February 2025.

Wow.  It's been more than a year since I last ran BitCrack.  And #64 is still unsolved?

Yep still unsolved

where the processed keys are stored, why the RAM consumption has not increased in 8 days, only 5.5 MB ?








You got your DP set at 64, you got to go through 2^64 keys to get a DP, lower your DP so you can collect more DP's. Then you need to save your DP's, example:

Kangaroo.exe -ws -w save.work -wi 30 in.txt
177  Bitcoin / Development & Technical Discussion / Re: Pollard's kangaroo ECDLP solver on: November 24, 2020, 11:09:46 PM
is there a bsgs gpu version out there, anywhere guys?
any news under the sun, love to read something new and great
once again in here,

 Cool

Its not a BSGS with a GPU yet and no new updates yet.

How can i use saved work file for another public key?

You can't do that, you will have to start over with a new public key.

I'm getting tired of every other post about bounty hunters, they should do something else that can at least guaranteed them money then instead of whining and complaining when the bounty hunters are the main ones that's quick to dump the coins to make a few bucks. The bounty hunters are to blame for how they get treated. If you're still a bounty hunter in 2020 and beyond that, just find something else to do.

Jean_Luc, from your github readme:

A Pollard's kangaroo interval ECDLP solver for SECP256K1 (based on VanitySearch engine).
This program is limited to a 125bit interval search.


Did you make a program limit up to 125bit search space or mentioned this just for practical reasons?

this is for the GPU, but there is no limit for the CPU

Where did you see that?
