So you think it would be a "big integer" in base10? A private key in base10 would have to be 77 characters long. Any ideas for combining a 21 digit number and a 27 digit number to end up with a 77 digit number?

No Sir, I am almost 100% sure that there is an one way more as I put in my last post, that can be solved by that way without playing with changing, making, converting some hashes/words into the numbers.

Do You remember that 1BTC puzzle with natasha otomoski? The answer was exactly corelated to the puzzle question so I suggest only it is almost directly translation from the words to the numbers.

As You can see they told already that the priv key is a "big integer" so basically it is not a sha256 hash in my opinion.

To be honest I don't really see any other way that can we convert those words for exactly 27-digit number.

If you see my post above, all the characters of "Phemex", "BTC", "ETH", and "XRP" are present in Base58Check encoding, which is the method used to encode WIF private keys. This encoding also misses out the letters "I" and "O", since they are easily confused with lower case "L" and number zero, which could be the answer to the clue "Without I/O".

That's an interesting idea, but I'm not sure how the "without I/O" hint applies to using a phone keypad?

I'd suggest trying my method above in the first instance, by concatenating your 27 digit number with the 21 digit prime (both before and afterwards) and hashing them with SHA256 to get a private key. I would try it but I'm away from home and on mobile at the moment, and don't really fancy trying to do it manually on my phone. Tongue

Phemex made another tweet yesterday, saying they will release the final clue to the puzzle on Friday: https://twitter.com/Phemex_official/status/1228318202247237632

Hello,

This puzzles are really good, I spent a lot of time with trying to solve but without a positive results yet.

I want to share one of my point of view that You can use to solve this riddle by yourself;

1. Open -> https://www.geeksforgeeks.org/convert-sentence-equivalent-mobile-numeric-keypad-sequence/

2. Scroll down and at the bottom look for section "48" in C++ with "string input" and remove this word "GEEKSFORGEEKS"

3. Between " " put Your random words e.g "PHEMEXBTCETHXRP" OR "ETCPHEMEXBTCXRP" and above all numbers on the left side click Play button to get a result

4. In the section "Output" You should get 27-digit number, to make sure it is go to this page -> https://www.lettercount.com/, paste the results and check.

And if You have 27-digit number You are at the 50% of the road for 2.1 BTC but now I'm really don't know what should I do with that number next, so...

Good luck!

Edit : Been reading the discoveries of other members and I am really confused that they include number 9 and number 6 as a prime number. They are composite, not prime.

Lol

6 and 9 are digits

But they were asked for prime number consisted from 21 digit! For example, number 269 is a prime number but includes digits 6 and 9 as well Wink

Thanks for that explanation.

I already get it when I saw this site where the value of e is so many I spent my time looking for it. It is grouped so that is how I already get it. Keep on posting hints/tips though, thank you.

I can try this one.

I will be trying the tip of the first member who posted here. Might win a 1.1 BTC but I think, and I know for sure that there will be someone who can answer this quickly.

What does "without I/O" mean in relation to the puzzle?

It, most likely, indicates Base58, which is by definition without I/O.

I/O specially written this ways refers to Input/Output protocol in communication protocols. not to mention that base58 is also missing zero and lower case letter L.
by the way "Base58Check" suggests a checksum in the strings which i don't think any variation satisfied that.

Base58 could be correct clue as "without I/O" is exactly without I, O, l and 0 because I looks like l and O looks like 0

So I assumed the "without I/O" clue was a hint to Base58Check encoding. Given that, if you take "BTCETHXRPPhemex" as a Base58Check string and convert it to Base10, you end up with a 27 digit number.

I took every combination of the words "BTC", "ETH", "XRP", and "Phemex" (24 combinations in total), and converted from Base58Check to Base10.

For every one of these 27-digit numbers (24 in total), I concatenated them before the prime, concatenated after the prime, and multiplied the two together.

For each of these 72 resulting numbers, I tried:
Hashing them with SHA256
Hashing them twice with SHA256 (the "Go back to step 4 again" clue makes me think we have to do something twice)
Converting them to HEX, then hashing them

I used each of the 216 results as a private key and checked the addresses. No luck.

I'm out of ideas at this point. Going to have to wait for another hint.

1) The first 21-digit prime found in consecutive digits of e is: 957496696762772407663
2) The private key you derive from Satoshi’s portrait is a big integer, not Wallet Import Format (WIF)
3) The filename of the picture is irrelevant
4) The next step involves converting some words from the portrait, without I/O, into a 27-digit number
5) Go back to step 4) again if you can’t figure it out

Words from the portrait, without I/O
First: 166598323
prime: 541576313

BTC, ETH, XRP, Phemex combo gives 27 digit number. So does "first,prime,found" and few others but BTC, ETH, XRP, Phemex makes more sense.

They have released the 21 digits prime number with their latest tweet and it says that some hints can be found on their blog.

I think still no one finds the correct answer until now, but there's someone who got the 21 digits prime number. Good luck to those who will try to solved the puzzle.

It's really a good strategy how they put up like this kind of puzzle, it's a good marketing having a 1.1 BTC plus 1 BTC as a bonus that's why they gained so much popularity now, for sure many project will have a marketing strategy like this one.

The 21 digits to find out isn't enough to solve the puzzle. It's actually the first step and I saw that guy on their twitter that got the correct prime numbers but nothing happened.

I think we will see now a new marketing strategy in the coming years for those exchanges that want to compete with other established ones. And this is going to be through puzzle solving with high hidden prizes.

It's a puzzle for math people.

Are you sure it's all about math ? Can be the wrong path.

i honestly wouldn't call this a "puzzle" because a puzzle is when there is some sort of problem that you think about and solve with different hidden clues.
this seems like a brute force attack specially after i read their latest tips, they are basically saying you should try different values (that is brute force) until you find the answer which is far from how a puzzle should work.

Puzzle is so difficult to solve trying hard from 3 days. Couldn't find it but still I am trying yes the puzzle is worth 1.1 Bitcoin. One cannot earn so easily. It all depends my my luck what I got or not lets keep trying until it going to end

It's a puzzle for math people. Which I'm not. Not really even very fun to observe since I totally don't get what's going on. I know prime numbers. But probably never used one beyond 4 digits.

So I never participate in these kinds of puzzles. Maybe something more accessible would gain more traction. Otherwise you basically are giving away 1.1 BTC or $10k to just a small circle of guys who study math or engineering or whatever.

And miss out all the regular bitcoin users who actually go on exchanges to give you business.

Just my simple non puzzling 2 cents:)
