Welcome to The Hunt for BCH Treasure!

This week, from Monday to Friday, I’ll be giving away a daily prize of ~$5 worth of Bitcoin Cash (BCH) to the smartest, and quickest, participant who can crack my puzzle. It’s first come, first serve, so you’ll have to be fast in order to unlock and claim the treasure!

Do you have what it takes to crack the code?


Here’s how to works:

  • A BCH public key will be provided with ~$5 worth of "buried" BCH.

  • I’ll provide a treasure chest with a QR code and a string of text, called a BIP38 private key, that is password protected with the answer to my puzzle, shown below. The answer will be in all lower-case letters and/or numbers.

  • Once you think you’ve uncovered the answer to the puzzle, use it to decrypt the BIP38 private key and reveal the underlying BCH private key corresponding to the BCH public key shown. There’s multiple ways to do this. Here are two ways:
  1. If you have the mobile Bitcoin.com wallet:

a) On the home screen, click “Scan”, and scan the BIP38 QR code.
b) Click “Sweep paper wallet”. Enter your answer to the riddle as the “password”.

2. If you have another mobile wallet, such as the HandCash wallet, or a BCH wallet where you need to access the BCH private key QR code or text:
a) Visit "BitAddress.org" and click the “Wallet Details” tab.
b) Copy and paste the BIP38 private key into the “Enter Private Key” field. Click “View Details”.
c) Enter your answer to the puzzle in the “Enter BIP38 Passphrase” field. Click “Decrypt BIP38”.
d) If successful, the private key will be revealed under “Private Key WIF”. You can scan the displayed QR code or copy and paste the BCH private key into your personal BCH wallet.

  • Once the BCH private key has been unlocked, you can import and sweep funds to your own personal BCH wallet!

I just claimed it, this was awesome ! This article was 4 hours old when I read it and it took me 15-20 minutes. Here is how I processed for those interested (spoiler ahead):
The code made me think first of some binary code because there was only 2 characters "dah" and "di". I first looked for binary converters but the amount of numbers did not fit.
I then looked specifically for cyphers that use "di" and "da", and found that this was actually a way to encode morse. I discovered this page which made me certain I was on the right track:
Now you must know that when I started this it was 100% for the fun of deciphering a secret code, I didn't even checked if the bounty was still available, but now I realized that it was possible I could decipher the whole thing and claim the bounty so I decided to check if the bounty was still available, and it was. I started to get a bit nervous with thoughts like "what if someone else is searching at the same time and finds it before me ?"
From the website for example the first letter "di-dah-dah" is actually "W", so I rewrote the entire code on a notepad and went about decyphering the letters one by one, I got this:
1) di-dah-dah di-di-di-dit di-dah dah 2) di-dah-dah dit di-dah di-da-da-di da-da-da da-di 3) di-di-di di-da-di-di di-da da-di-da-da di-di-di 4) da di-di-di-di dit 5) di-da-da-da di-da da-di-di-di da-di-di-di di di-da-di di-da-da da-da-da da-di-da-di da-di-da 6) di-di-da-da-di-di
1) W H A T 2) W E A P O N 3) S L A Y S 4) T H E 5) J A B B E R W O C K 6) ?
I then searched the sentence "what weapon slays the jabberwock?" on google. I found references about an old game called "NetHack" that was an online collaborative work and a Lewis Caroll poem.
In the poem, the Jabberwock is killed by the vorpal sword. This is why the VorpalBlade is an instadeath for Jabberwocks in NetHack.
Okay so I knew I had to combine words to test all variations of "the+vorpal+blade" or "the+vorpal+sword". I used https://www.bitaddress.org/ as described in the article because testing the password on my phone was too slow.
At first I wasn't sure if I should use spaces or not, and if the answer was several words or just one, I got very unlucky and tried all these in this exact order :
vorpal vorpalsword vorpalblade thevorpalsword thevorpalblade the vorpal sword the vorpal blade vorpal blade vorpal sword -> SUCCESS
thank you very much @Prometheus101 ! this was an awesome experience and allowed me to learn about a few things I had never heard before like the game NetHack.
edit: @Yoonski, just saw your comment. Damn we were indeed both searching at the same time ! and you had the right answer, well played

Just tipped you $0.25 for the good work.
For people interested in puzzles I also have one that has been running for about 6 weeks now. The prize is larger, but the problem is also much harder. It can be found here.
