Good job. That was a fun puzzle, with a couple of tricky clues in there. 1 down in particular was left until last and then almost brute forced from the known letters. I was thinking along the lines of "proofofwork" or "distributed" initially. Looking forward to the next one!

I'll include my solution in a link rather than embed the image so as not to force spoilers on anyone still trying to solve it themselves.

Solution - https://i.imgur.com/x5jbU2o.jpg (https://i.imgur.com/x5jbU2o.jpg)

This is what I was looking for. I am fond of answering crosswords but sometimes I got annoyed if I really can't get the right answer and I need to do some research for me to increase my knowledge more about crypto or other information. Since this is bitcointalk then this is important for newbies to learn and have fun at the same time.

Let me guess the 8 across - its hilariousandco!!! It is the easiest among the others as we already know the S lol.

This game is fun tho. Soon if I could have enough time I might create a simple web app that could be a crossword game. It's a great idea tho! Sounds a lot of fun to play. Will try finishing this on my spare time  ;D Also, if you have already tons of crossword puzzles, I'll send you a PM so I will integrate it to an app.

I know I'm probably not supposed to ask questions but is #7 also directly related to BTCitcoin?

I've been trying since last night to solve the last one ^[#7] but had no luck ^{[SS of my results without revealing the answers (https://i.imgur.com/0p9gqcI.jpg)]}...
^{- I'll update this post if somehow I manage to make it right but I highly doubt I'll be able to; At this point, I'm just guessing words that have nothing to do with BTCitcoin [my head is exploding].}

Update:
Thank you for the added clue, I appreciate it :)
^{- I've been searching for the past two hours with no luck [I'm going to stop for now and resume at night].}

Update 2:
Thank you for the added clues but unfortunately, I think I've been either cursed or my brain just automatically shuts whenever it sees the word library ^[SMH].

Update 3:
Thank you for the detailed explanation ^{[I'm pretty sure I wouldn't be able to find it without you giving me the answer]}...
^{- Honestly, I don't think I deserve those merits but I do appreciate them [thank you so much] :)}

• Btw, here are the solutions for those that are wondering:
  
  • Puzzle #2 (https://i.imgur.com/cBdaT4S.jpg)
  • Companion (https://i.imgur.com/zSWybKj.jpg)

Finally, I solved everything this time :)
<sup>- This one was relatively easier than the previous one but I almost gave up on finding the answer to number 8.
- I'll stop doing puzzles now so other members would have more opportunities.</sup>

For those that are wondering about missing answers on the previous puzzle, I've added those to my previous post here.

Update:
Likewise :)
^{- I'll be following this thread silently.}

I did ^{[more than I expected, quite addictive]} :)

These are fun, keep it up!

The last one was pretty easy, got most of the answers straight off without having to think. I won't share the solution so other people have a chance to earn merit, but I'll share my zero-knowledge proof of completion: https://i.imgur.com/sWPra0P.jpg

You are doing nice job, soliton! I tried to solve the second one the other day but was only able to guess 3-4 after devoting around 10 minutes and then dropped it. The fourth one is relatively easier and I was able to get all but 2 in five minutes. Here are my solutions: https://i.imgur.com/lCzsNe4.png

I know the 'payment type' one is easy, I already got five correct letters in the word. But my mind is playing with me, can't hit on the word. :D Give me the solution now, can't bear it anymore. ;D

I spend some time finding the correct answer of number 3 and 5. i have a feeling that the answer of number 5 starts in "TRA" but I just can't think that it is the trampoline payments. Meanwhile, I also tried to find the dusting attack but it seems thta I can't find it in time before the answer is revealed. Better luck next time. I have fun answering and learning at the same time, also it brings me to other bitcoin related topica during my journey of finding the answer.

1. genesis
2. wasabi
3. dust
4. stratum
5. trampoline
6. salt
7. glacier
8. taproot
9. liquid
10. verify

I surrender. It seems I can't fully answer all the puzzle, I am having fun looking for answers but sadly I can't find some of the answers. I think the clues are a bit deep. I was getting close as I only have 3 left clues to look for answers. I have spent 4 hours answering puzzle #5. You are right it is a bit harder in your POV but mine is much more harder  ;D ;D ;D.

That was smooth!

---

Not really. #5 is not as hard as the initial ones. I gave a try to it and got most of them right. But I won't destroy the fun like last time so won't be posting the answers. Here are the ones I was able to solve though: https://i.ibb.co/3fZLLSm/Screenshot-20210416-113454-01-01.jpg

Okay, It seems you got the right answer of other puzzle. I only need three more answers to find which is the number 9, 5 and 3. I am having a hard time finding the answer of boolean script operator. It didn't take me too long to answer the rest  which I asnwered it smoothly. That three clues is what I didn't get the answer and spend 4 hours finding it as I mentioned in my previous post.

Why didn't I think of checking the full list of op codes. I could have found the answer sooner LOL than late. Anyway, this crossword puzzle did help me to learn and also this will also test my knowledge about crypto. Some clues made me do some research and sadly did not find it as I have been passing the answer. I have been checking the codes but did not fully check the codes. Here it is, all answered correctly https://i.ibb.co/XWtkSv5/Screenshot-20210419-105949.jpg.

I am so much lost here I have tried hard to flow along yet the puzzle keeps looking strange each time i stare to get a glimpse of what's going on around the block can I get a hint please

Guess I came late to the puzzle since is limited to the first two person,would have tried my hands on it

True, I only manage to answer puzzle number 5 as which no one tried to answer all of it and later on someone did answer puzzle number 5 until I got a clue which I finally got the right answer. Imagine, for each puzzle posted in here I only got the chance to answer puzzle number 5  but now you got a chance to answer puzzle 6  as mentioned on quote above that you are not late. Good luck. I even created one crossword puzzle myself. If you like I can share the link and provide answers if yoi find it hard for further learning.

Eagerly waiting for the new Crossword bitcoin puzzle by you and will surely try to crack all the answers as missed the previous one and even not will learn something from them.So eyes are dead locked on it for what you come up with this time.

Sick! Just discovered this topic earlier and doing the crosswords, just solved a few so far. I also learned new stuff and refreshed my memory on a few concepts, really great.

Crossword 6 is not yet solved, right? I'll try that first then, before the other missing ones.. ;D

---

Indeed, 7 is tricky but my only other missing one is 4, I think I'm close since you say it's an easy one! Number 5 was one of my first ones, though :p Damn, what the hell is a block guard ;D
Edit: Got number 4, it's very easy indeed! I was looking for address formats or such.  ::)

Intermediate progress:

Oh yes but no solutions published ;)

Alright, now I have all words. But the clue is actually wrong in my opinion. The timestamp doesn't guard anything; in fact, a later block can even have an earlier timestamp than the previous block, that's not an issue as long as it's not too much deviation.

Here's a good article about it: https://blog.lopp.net/bitcoin-block-time-variance/

Spoiler, here's my solution:

I just tried the URL: https://crosswordlabs.com/view/solitons_bitcoin7 and found a new crossword! Solved it already, too ;D
Was small, but fun! Here's my proof:

https://i.postimg.cc/8CDsPhPZ/crossword7.png

Alright, I guess that makes sense, so in that way anything that is part of the block hash is a block guard :D

Ok, I got it now as well! There were some tricky questions. That cache was new for me!
https://i.postimg.cc/xT9x164N/puzzle7.png

Cool thanks! I'm down to 2 missing words so far! 9 across wasn't too hard though ;D
I didn't know about that kind of attack (5), very interesting way to fool someone into accepting a transaction after seeing 1 confirmation and then it's invalidated again afterwards due to chain split.

Edit: got it! :D
To let the others still try it, I'll add a new post (no edits) with the signature to the solution URL. Will add the URL to this post in a few days or so!

I need to add a new post so there are no edits and it’s sure I won’t edit this message later ;D

Oh sorry, I didn't officially 'stash' a Bitcoin public key so far, I only did a signature once in this thread (https://bitcointalk.org/index.php?topic=5300698.msg57869126#msg57869126), so it shows up in my addresses section (https://ninjastic.space/user/n0nce?addresses) on Ninjastic! Reused that, hope it's fine :) I think I could have also sent a blurred screenshot again, but this is more cypherpunk ;)

For the attack; I looked around the web for 'Bitcoin attacks'; but as always in these crosswords, that's one of the trickiest question since this search term brings tons of crap, like exchange hacks and the like and never actual real attacks. This makes them so fun though! :D Let's say, I found the answer in a place most of us here know very well.... ^^

It seems soliton is back for more puzzles to be answered. I was mentioning this thread on the other thread called give this bitcoin test as it reminded me of this puzzle I managed to answer before. Good to know this was updated. Thanks once again. I managed to help a fellow forum member to test his/her knowledge about cryptocurrency.

Thanks for helping me in dissemination the info on  soliton's Bitcoin crosswords. You are among those users who were known to be very active  on solving them in the recent past. Why don't try again? Both #7 and #8 are still opened for every forum user.

I was actually thinking if it's possible to create a zero-knowledge proof so someone can prove they solved a crossword, without posting the solution directly, but couldn't come up with something good so far. I should probably do a web search; if it's possible, someone has certainly already done it.

Anyhow; I forgot to post the solution, but I guess since tomorrow marks exactly 1 week, I will add it tomorrow, hopefully someone else can find a solution as well :)

Thanks for the invitation for solving your puzzles once again. I'll try to solve your puzzles when I have time. For past few days we are experiencing a very strong gust of wind, I think it's a low pressure. Anyway, nevermind the weather condition I just said. I made my own puzzle with the help of the platform you used to make the puzzle but I only shared it to my friends and those who I taught about crypto.

These crosswords are fun! :D I'm down to the last 3 words, just want to let you know I'm on it, even though not as fast as the last times! ;)

I'm not sure how to solve the 8 across. I fetched a list of usernames here (https://loyce.club/Merit/usernames.html), filtered with a Python script for the ones with correct length and correct second letter (missing 1 down still) and then scanned the matching usernames via HTTP requests to check if they're Senior Members. I got a list of around 100 and none worked in the crossword.

So it means the username list I'm using is not containing the user we're looking for. I'm not sure through which criteria users are added into that list, but I think Loyce puts the ones in there who earned merits in the last 30 days or something like that. So now I'll look for accounts which became inactive, instead, I guess. Or I'll try solving '1 down' first ;)

Well, wasn't 'colossal' effort but it took a few minutes to write the code ;D
Lol, I just tried something that I was sure I had tried before, after you mentioned the 'event' again and it worked! Probably, I tried to put it into 6 across instead of 8 across, since they both have same length and same second letter (hint for others! ;))

I hope I can finish the last two words now! :)

With this hint i think it became easy for me to guess #8 across and now have one member in my mind which is fitting to this length but not disclosing it and working on the rest to complete the whole puzzle box and then upload the full image when all the answers have been found by me.Rest members try hard to find the answers for the one you can.

Finally, I was able to solve the crossword! This one was the most challenging so far, I think. At least I spent the most time on this one.
Since it's been online for over a week, I will just reveal the solution 0:)

To be honest, for the first time I read the actual article about the 'Chancellor on brink of second bailout for banks', so that was cool as well!
