what calculation do you have made

*Insert random numbers
*Insert random logic

Puzzle 125 starts with 1A. I understood it
Lol, weren't you satoshi himself just yesterday? You should already know all the keys of all puzzles!

My estimations are rounded up numbers and they could be inversed/ backwards, since I calculate from greater keys down the bit range, I could be 99.99% off the correct path, I am still working on validating the exact range, though if the puzzle key was out of the 2^125 range, like in 128 bit, I could tell according to my calculations.

The keys and their value representations I provided above are for simplicity, though we could calculate the keys based on decimal values of bit ranges.

For example, we could consider 2^124 as 16 in decimal and 2^125 as 32, we could as well call 2^124  "21" in decimal, I chose to represent 2^124 as 1000 in decimal.

The other miscalculation of mine could be due to the fact that I focus on hexadecimal representation of keys too much, therefore I could have confused the hex characters with their mirror versions, i.e, if we divide "a" by 2, we would get 5, dividing 1 by 2 will result in "e" and depending on each character on the right side of a hex character, the result of dividing them could differ and cause more confusion, which is why I might be off with my numbers.

One thing I have failed so far to figure out, is to subtract a key from another key to land on a rounded key. But my random logic and random numbers stop me from moving forward.😉

ECDLP solver based on the Pollard's kangaroo method https://github.com/Etayson/Etarkangaroo
Gpu math is mostly based on JeanLucPons code https://github.com/JeanLucPons/Kangaroo/blob/master/GPU/GPUMath.h
But with some additions and modifications.
Supported Nvidia GPU architecture >=SM75
Range limited to 192bit
Initial kangaroos generation happens on GPU which is slightly faster.
You can save kangaroos after certain time interval and with saving hashtable you can be sure that after restart program will continue job.
It is possible to reset and save the hashtable after a certain time interval, followed by automatic merging into a single hashtable.
During the merging, you possible to find the desired key, and also the merger fixes the dead kangaroos and signals the GPU to reset them.
You can use server/client app for Etarkangaroo https://github.com/Etayson/Server-Client-apps-for-Etarkangaroo

GTX 1660super with -grid 88,128 and PL60% Memory +500 speed 890Mkey/s, PL90% Memory +500 speed 1000Mkey/s,
RTX 3070 with -grid 92,256 and PL56% speed 1535Mkey/s
For Windows only.
Purebasic v.5.31 required for compilation
Do you have a binary which doesn't require compiling? The nvidia arch should also work for other nvidia systems right? If you could release a binary it would be great.

1324  Bitcoin / Project Development / Re: Seeking Professional Input: Participation in an Academic Survey about STOs on: June 29, 2023, 11:37:12 PM


Hello BitcoinTalk nation.

I hope this post finds you well. I am reaching out to the members of this esteemed community to request your valuable input for an academic survey as a part of a scientific research concerning ‘Keys for a successful Security Token Offering from investors’ perspective’. This topic is very important for the development of STO field both for investors and issuers in order to promote success chances in the offering.
The purpose of this survey is to gather insights and actual STO’s investors’ opinions on their motives to invest in STOs which consequently drives the STO successful. Your participation will significantly contribute to the depth and quality of the research findings. By sharing your knowledge and experience, you will help advance the global understanding in this field.

Rest assured, your responses will be treated with utmost confidentiality and anonymity. The survey will take approximately 3 months to be completed. Regarding the significance of the topic, the results of this survey will be communicated to interested participants at a further point.

To participate in the survey, please click on the following link:
https://docs.google.com/forms/d/1ts9XzEKM-6NvIi64ZaMrcm6WlKk48YxkNZ9bfCswGYQ/prefill

If you have any questions or concerns regarding the survey, please feel free to contact me at wessleti.hamza2@gmail.com. Thank you in advance for your consideration and willingness to contribute in the survey. Your participation is invaluable, and sincerely appreciated.

Best regards, Hamza Ouessleti.

Just another form of scam, or a way to scam people more easily, since people are wary about the ICO scam episodes, STOs will ensure them there is regulation, etc. Well sigh!

Since we can't predict the future success of any company/ business, investing on it's STO is no different than gambling, and guess what? If an idea, a business is 100% ensured for success, no one would share the certain success with the world, if they lack investment, they would seek private sponsors in order to maximize their own profits.

So in other words, STO is a platform for quick money grab, as soon as the exchanges open the trade, people would dump for profit while others are buying in hopes of more profit in the future, and what happens if the business owner, company owner decides what he has is enough and turns away from moving forward seriously?

Success of a business depends on those conducting it, if they don't really feel the need for succeeding, they won't try to succeed.

I wonder, how can I launch my own STO? I have so many ideas. 😉

Hi dev, a suggestion : could you make it so the user could select how many threads to be used? Since it uses everything a CPU can offer, usually it just hangs if the load is too much, unless you go to task manager on windows and limit CPU usage, but having an option to set one time and the ability to save the user settings would be great.

Why there is no activity around these woods? Chop chop people, get to work.
If it helps, I am 99.99% sure that puzzle #125 starts with 1a. I just don't know how could that be of any help other than lowering the bit range, but if there is any secret behind it, do let me know.😉

Something to work on. Please do your calculations and tell me if I'm wrong.

2000 (2^125) = 037e2cd40ef8c94077f44b1d1548425e3d7e125be646707bad2818b0eda7dc0151
1700 = (puzzle #125) = 0233709eb11e0d4439a729f21c2c443dedb727528229713f0065721ba8fa46f00e
300 = 0286936a275e6d53bb2b2718c93d8a5aa44f371f6e0300abb73b89dd851d2fbe88
700 = 03ed01ff219ed5c1afc12d991a82e3063ddcee1fd53b46f7cad52a0d87a7112aed
400 = 02a64a0b3739ddccddece6d90407c925717c75467cc8ce46321d73ec2663320130
200 = 0339ddd9a2a1a113c105175e17903c1f72326ff89b109efc8b976cc9916429c9c4
100 = 031f45d50a743e772f27543272ff4aba36da659540af3185907ad08e68ed0eee4f

And here is 500 = 2^123

500 = 020bfc0504a4b3235d065c0d426b8675fcb2c85d6f58275d791b43e1fe44a6db03

0000000000000000000000000000000008000000000000000000000000000000


I will leave a quote from gmaxwell here, I don't know whether my calculations are proving the #125 is in the range between 2^124 and 2^125 or not?

With the help of someone knowing the secret they could prove it was in a range using a confidential-transactions like zero knowledge range proof. (which is exactly what CT does... proves the values are in  a range like [0,2^32) that couldn't overflow.)



1327  Bitcoin / Bitcoin Discussion / Re: Quantum Computers and their potential effect on Bitcoin collectibles. on: June 29, 2023, 02:15:04 AM
So you are worried that a quantum computer could somehow reverse the hash and extract the public key from your addresses and then brute force the private key to steal your coins?

How does reversing the hash back from an address through 2 hashes work exactly?

A quantum computer could be at most 100,000 times faster than a binary one, if you distribute your coins across several addresses, it won't be worth the effort to crack one address for just 1 bitcoin, if QC becomes a threat.
1328  Bitcoin / Project Development / Re: Large Bitcoin Collider Thread 2.0 on: June 28, 2023, 01:49:26 PM
I might sound stupid, but can some1 explain me how this "0x236fb6d5ad1f43" is a private key if in normal life the priv key is 51 characters (or 52) long?

This is the WIF private key for key 0x1
5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreAnchuDf

If you decode it, you will see this
800000000000000000000000000000000000000000000000000000000000000001a85aa87e

If you remove the last 8 characters and the first 2 characters, you will be left with 63 zeros and a 1.
What you have posted is the hexadecimal format, what I posted is wallet import format, wallets convert the hex key to WIF, or WIF to hex depending on what you are doing. 😉
1329  Bitcoin / Project Development / Re: Metalet Wallet: The Next Step in Bitcoin UTXO Blockchain Wallet Technology on: June 25, 2023, 09:29:53 PM


The use of blockchain technology has grown exponentially in recent years, and with it has come to the need for more secure and efficient wallet solutions. Enter MicrovisionChain, a cutting-edge blockchain that has been designed to solve the “blockchain trilemma” by leveraging the bitcoin UTXO model. And with Metalet Wallet, the first wallet extension based on this new blockchain, users can experience the many benefits of this emerging technology.

The UTXO (Unspent Transaction Output) model is an essential component of the Bitcoin blockchain technology. This system is designed to manage financial transactions more securely and efficiently than other traditional account-based approaches. The UTXO model works by maintaining a detailed record of all spent and unspent financial transactions on the blockchain network. Each individual transaction is recorded on a separate UTXO entry, enabling Bitcoin users to transact more flexibly, securely, and privately.



Advantages of Metalet Wallet



UTXO Model Support:
One of the major benefits of Metalet Wallet is its support for UTXO model wallets. This offers users enhanced security and performance when managing their digital assets. The UTXO model has become increasingly popular as it provides a robust and efficient way of handling transactions on the blockchain.

Cross-Chain Asset Support:
The Metalet Wallet offers cross-chain support for a wide range of UTXO-based public chain assets, including Bitcoin. This means that users can easily manage multiple digital assets from within the same wallet, without having to switch between different applications.

Customized Transaction Formats:
Metalet Wallet is designed to be highly interoperable, with a customizable protocol that can handle a wide range of transaction formats. This means that it can support a variety of complex use cases such as NFTs, DeFi, social networks, and other DApps.

Security and Privacy Benefits
One of the key advantages of utilizing Metalet Wallet is its enhanced security and privacy features. The integrated smart contract technology used by Metalet Wallet ensures that all transactions are conducted securely and transparently. This means that users can have confidence in the safety of their assets and transactions.

Furthermore, the Metalet Wallet is designed to be highly private, with all transactions being conducted in a secure and encrypted environment. This ensures that user data and digital assets are kept safe and secure.

Low Transaction Fees and Speedy Zero Confirmations
While low transaction fees and speedy zero confirmations are often attributed to the underlying blockchain technology, Metalet Wallet takes this further by offering an intuitive and user-friendly interface that allows for seamless and hassle-free transactions. All transactions can be conducted quickly and with ease, ensuring that users can access their digital assets or complete transactions without delay.



In conclusion, Metalet Wallet is a promising new wallet extension that offers a range of compelling features for users of the MicroVisionChain blockchain. The UTXO model is one of the main reasons Bitcoin has retained its position as the most dominant cryptocurrency over the past decade, and it continues to be a vital component of the broader cryptocurrency ecosystem. With support for UTXO model wallets, cross-chain asset management, customizable transaction formats, enhanced security, and low transaction fees, it has the potential to be a game-changer in the world of blockchain wallet technology.

Not open source? Meaning that you hold the private keys and all the funds, how do you lower the fee for bitcoin transactions? By offering a token instead of bitcoin like second layer/ LN?

Security wise, I wouldn't touch a third party centralized wallet, after all we are supposed to be our own bank and manager, otherwise why even move our funds from the hands of governments to the hands of total strangers? At least with governments you are ensured they don't run with your money.!

I am also sure you could use known addresses to compare and skip this information. In my case I did not know the address I was looking for. It was 64kb of a corrupted wallet of my own from 2009....

Is this the private key you were looking for?   3030303030302033303331203330333020333033302033303331203331333120

How can you not know the addresses? After all, you mined them all and their addresses exist on block chain and any explorer, but the main question is, why are you looking for Satoshi's addresses from 2009? This is disappointing.

Wait , are you saying you are Satoshi? Are you familiar with our ancient tradition? We  call it circular gangBJ, whenever a former clan master returns we make him to give all clan members BJ while we stand in a circle.🤣 I hope you have good knees because you'll have to be on them for a while.   Welcome back. Lol


No offense to @real_Satoshi.
1332  Bitcoin / Bitcoin Discussion / Re: Which wallet does this hash go to? on: June 25, 2023, 03:01:18 AM
You cracked a password with a length of 38 characters? I just wonder whether this imaginary owner is retarded or what to search for a password for a wallet which he doesn't have?
Why would you crack a hash without first having the wallet?  Do you have the address of the wallet? How many coins are we talking about? Is the public key known? I might have the wallet, just need the addy to check.😉
1333  Bitcoin / Bitcoin Discussion / Re: == Bitcoin challenge transaction: ~1000 BTC total bounty to solvers! ==UPDATED== on: June 25, 2023, 02:50:08 AM

Assume you possibly have a very old wallet that is corrupted. The wallet is your old wallet and may have a balance. Is it very smart to check for balances online. Use tools online? Or you could sync a full Bitcoin node and import keys to check offline on the full node.

I think offline is smarter and secure. Kind of what Bitcoin is about.
That's a lot of old wallets, I mean maybe Satoshi is the only one with more than 20,000 valuable keys, so no, it's not a good idea to involve bitcoin core or any wallet whatsoever, around these woods the residents tend to pick every address with a balance  more than 0.01 ( some go for lower than that ) and input them to whatever tool they use when they search the key space.  Just wanted to tell you that you are doing it wrong, and checking balance has nothing to do with security, you could use a block explorer via api to check for balance.

I guess you are lost and stumbled upon our garden, something tells me you don't even know what this topic is all about. Lol

1335  Bitcoin / Development & Technical Discussion / Re: ripemd160 - collisions on: June 24, 2023, 03:28:27 AM
Look, stop mixing things, you could hash whatever you want and extract addresses from them, I even found an address with more than 70 BTC balance, it has a colliding RMD hash.

When I was working on hashes, I found so many interesting things, like hashing an address with SHA-256 and then RMD-160 to arrive at the same address again, can't recall exactly, when I have the time to go through my laptop files, I will show you so many things, like finding your desired checksum using WIFsolver tool etc.

Take this address,
12zqc8j8Btu8fvDbTTky9PXEMkd9ub5K5s
Perform SHA-256 on the first 2 characters "12" and Perform RMD-160 on the hash 256 then convert to address, you will see the same address, coincidence? Definitely.

Hash 160 (sha256+rmd160) of (converted to address)

12 = 12zqc8j8Btu8fvDbTTky9PXEMkd9ub5K5s
14 = 16gbG4hC3sTsZXn47KG6uWcjN8ww6EB5Xi

Here, a magic trick!  Just perform sha256 on the following address  ,12noFjFNrtaCcBDMZ5ZMpJQbUPLD4MGpL6 or "12"  3 times, then use the third hash as private key to generate uncompressed address, tell me what you see? 😉 this happens when you mix base58, rmd160, sha256 and secp256k1. Totally normal, I was so excited first when I discovered all of these, now I spend my time on the real deal stuff (public keys + & - ). 🙂

How long would it take you to verify 5,000,000,000 possibilities?

less than a second
.      

How is that done??  I guess it’s with RTX? Which one ?How many?
Using BSGS/kangaroo, you could check Tk/s (trillion keys, thousands of trillion keys per second), GPU is much faster than CPU in this case.



The script posted on previous page won't work, it's just dividing one key, in order to successfully divide a key, you'd need to make sure that the key is +n and also even, since we don't know it's odd or even, we'd have to assume our original key is odd, then we'd add 1 G to it, then divide both, we will then treat the results as same as our starting keys, adding 1 G to each one and dividing all, keeping all the keys, how many times we divided, how many G we added, they are all important.

But note that when you divide a key, the result could be -n version, adding 1 G and dividing that -n key will get you no where, so you'd need  to do all the operations on both -n and +n keys. This should take less than a second if you have the proper algorithm implemented with the correct tool!
1338  Bitcoin / Bitcoin Discussion / Re: == Bitcoin challenge transaction: ~1000 BTC total bounty to solvers! ==UPDATED== on: June 23, 2023, 11:01:46 AM
Basically yes it is the same, But because there are a lot of invalid WIF formats you could print only the valid ones, and then check them for valid keys. I guess if you could output valid keys very quickly and dump invalids even quicker it might be faster then what we are currently doing. Based on hardware limitations that I know about software is much faster at ignoring a input. However with the uncompressed byte being less it may be at least 1 byte less to scan. I guess its just a different way of looking at EC operations from the other end. And BTC core can handle 20,000 plus keys at a time during a scan. I know because I lost my own genesis wallet, and have tested it. And software can ignore something much quicker then process it.

If this helps someone please don't forget the little guy still learning python. And sorry if I sound a little special.
Why would you go all the way to check WIF? You'd first need to generate the public key, hash the private key twice, add checksum and convert to address. That is not how you special people should go about it!

Normal people use BSGS, kangaroo to only look for public key match, rookies like me, we go for add/subtract method, wifsolver is very slow comparing with kangaroo.

And about scanning,  what do you mean bitcoin core can handle 20,000 keys? Do you check for balance in every key you generate? 😳
