As the name implies, Bitcoin puzzle transactions are created as a challenge and not for the usual purpose of monetary transfer.
Puzzles can be published for several reasons, including software test bounties, marketing campaigns or just for fun.
Early Puzzles
In the early days of Bitcoin, when $BTC coins could be found for free on the WWW, it was common to set up challenges involving large amounts of coins. (Even legitimate Bitcoin faucets were commonplace back when the monetary value of BTC was in the pennies range. “Free Bitcoin” was actually a thing!)
These early puzzles normally stemmed from technically curious groups, cryptographers, cypherpunks and others who wished to test Bitcoin’s resilience against distributed attacks.
As Bitcoin gained higher financial value, the “naive puzzles” of yonder slowly disappeared.
Marketing Stunts
Bitcoin puzzle transactions are now usually part of some marketing campaign, such as for promoting a website or product.
Challenges with very high potential rewards have the potential to generate instant buzz, receive inbound WWW links and get loads of free attention.
Bitcoin puzzles are still an excellent marketing tool. A Google search for “Bitcoin puzzle” will yield recent news articles mentioning large unclaimed prizes. Some Bitcoin puzzles go back several years, such as this one mentioned on Bitcointalk.
Every Bitcoin Address is a Puzzle
Time for a rather controversial realization : every single Bitcoin address out there is a Bitcoin puzzle!
Think about it.
What protects a Bitcoin address from someone who could steal its funds? The fact that the private key, from which we derive a public key address, is not known. If we could somehow crack this puzzle, the funds would be readily available.
Therefore, every single address out there is simply a mathematical puzzle that is very hard to solve.
In fact, solving this puzzle is more expensive than the money contained in those addresses, thus the safety of Bitcoin’s encryption.
Bitcoin puzzles can be controversial for several different reasons.
For example, there is no way to verify that the winner isn’t the puzzle creator himself. Remember, Bitcoin addresses can be generated for free. Prize winners wouldn’t identify themselves, either for their personal security or other reasons. This would make a legitimate winning address just as valid as a fake one generated by the puzzle creator himself.
A different type of fraud is perpetrated by creating zero possible solution games.
Basically, if a scammer is able to raise a high enough amount of BTC to grab the community’s attention, and then proceed to generate a phony puzzle, which has zero possible solutions (random numbers) with a high bounty placed on it, it becomes impossible to audit the process without having access to the private key which created the puzzle.
Challengers could end up spending countless hours in vane, not knowing the puzzle doesn’t have possible solutions.
Some puzzles offer a signed message as proof of BTC ownership, which is fine for the purpose of proving that the funds do belong to (or have been under the control of) the puzzle creator. But there’s also no way to know if the winning address is owned by the puzzle owner himself.
Seeing how several puzzle addresses (see references) now display zero balances, it’s possible that the original BTC owners themselves withdrew the coins after Bitcoin gained significant value in recent years.
We’ve reviewed several Bitcoin puzzles for this article and several of them have all the characteristics of bogus Bitcoin puzzles. In one case, the winner was never identified, the amounts involved were quite high and the time it took to solve also raises questions. Of course, it’d be inappropriate to name names, given we do not have conclusive evidence, but to our readers we say this: if you feel like a puzzle is too good to be true, or that there’s something fishy about it, then it’s OK to be skeptical about it. You’re not alone and there’s definitely no such thing as being too careful when it comes to cryptocurrencies.
2020 Bitcoin Image Puzzle
The image below purportedly contains U$ 2000 worth of Bitcoin. It’s a new Bitcoin image puzzle, not the 2019 one.
The search for solutions to Bitcoin puzzles is the most fun part. Imagine the excitement of actually finding the private key that solves an address?
Bitcointalk has an interesting thread where several puzzle solving scripts get posted all the time.
Some Bitcoin puzzle solution searching scripts expose the sheer computing complexity of Bitcoin, with tens of nested loops where each loop computes a particular hexadecimal power.
Bitcoin Puzzle Solutions
Some newbies ask what they need to do to find a Bitcoin puzzle solution.
The reason most puzzles don’t specify what the solution is, is because it should be kind of obvious 🙂
There’s only one real solution to a Bitcoin puzzle and it’s the address owner’s private key! Every real puzzle should always have the private key as the solution. This guarantees that the puzzle solver can redeem the Bitcoin himself in a completely trustless manner, as should be.
Unsolved Bitcoin Puzzles
As we mentioned earlier, basically every Bitcoin address is an unsolved puzzle. But, if you wish to play with ethically correct puzzles, here is a list of puzzle transactions. If you scroll down the screen you’ll find parts of the puzzle which are still unsolved. Since these were designed to be broken, it’s OK if you find the solution and transfer the Bitcoin over to yourself.
Is it legal to break Bitcoin keys?
Breaking others’ private keys and taking their Bitcoin is unethical, although the legality (or lack thereof) of it would depend on each jurisdiction.
In the grassroots philosophy of Bitcoin, if you find the private key then you own the coins – no questions asked. But, in the real world, there may be other legal implications, so make sure to ask a professional if you feel like you’ve hit a legal gray area by accidentally finding a valuable private key.
Bitcoin Puzzle Box
In 2019 there was a Kickstarter project launched to design a Bitcoin puzzle box for playing cards. It’s not really a Bitcoin puzzle, but an artistic rendition of something resembling one.

The puzzle is finding the random number that, when added to the block's header, generates a hash with some number of leading zeros. Trying a new number trillions of times per second, the miner algorithm attempts to find the one that generates the desired results.
A mathematical puzzle that miners must solve on proof-of-work (PoW) blockchains in order to add their block to the chain. After Ethereum switched to proof-of-stake (PoS) in 2022, Bitcoin remained the major PoW chain. For the Bitcoin puzzle, see cryptographic hash function.
A cryptogram is a type of puzzle that consists of a short piece of encrypted text. Generally the cipher used to encrypt the text is simple enough that the cryptogram can be solved by hand. Substitution ciphers where each letter is replaced by a different letter or number are frequently used.
A popular strategy is to put the edges of the puzzle together first because, with one straight edge, the pieces are easier to identify and put together. “There isn't a single strategy that will work for 100 percent of puzzles, but in the majority of cases, it is easiest to start with the edge,” McLeod says.
Bitcoin mining is the process that validates Bitcoin transactions. It consists of mining systems competing with each other to solve a cryptographic problem and awards bitcoin.
But Bitcoin isn't actually backed by anything physical—only the complicated mathematics underlying its blockchain technology and controlled supply. This ensures Bitcoin remains limited in supply and is resistant to censorship—which imbues it with some of its value.
Mining is a metaphor for introducing new bitcoins into the system because it requires (computational) work just as mining for gold or silver requires (physical) effort. Of course, the tokens that miners find are virtual and exist only within the digital ledger of the Bitcoin blockchain.
Recall that in the Bitcoin system the miners are in constant competition: Whoever solves the puzzle first will earn the honor of adding a new block to the block-chain and make some money as well. Hence, the miners try feverishly to be the first to solve the puzzle.
But the odds of winning the $2 million grand prize by solving MSCHF's jigsaw puzzle? Two in 600,000. That's how I justified buying two puzzles—one for me, one for my family. You can't win if you don't play.
Stefan Thomas went viral this week after a New York Times profile revealed to the world his unsettling dilemma: The password to unlock his Bitcoin fortune is locked in a hard drive that gives users 10 attempts before wiping clean. Thomas has just two more tries.
To decode the fictitious message in the cryptogram, begin by grouping each set of two letters starting with the first two letters (FG) and continuing through the message. The code letters are arbitrarily arranged in groups of five letters. Some letter pairs will carry over from one line to the next.
There are three general classes of NIST-approved cryptographic algorithms, which are defined by the number or types of cryptographic keys that are used with each.
Hash functions.
Symmetric-key algorithms.
Asymmetric-key algorithms.
Hash Functions.
Symmetric-Key Algorithms for Encryption and Decryption.
Secret-key cryptography is also called symmetric cryptography because the same key is used to both encrypt and decrypt the data. Well-known secret-key cryptographic algorithms include Advanced Encryption Standard (AES), Triple Data Encryption Standard (3DES), and Rivest Cipher 4 (RC4).
It doesn't take a genius to figure out that puzzles boost our intelligence because they force us to focus, remember, learn new words, and use logic. In fact, figuring out puzzles can increase your IQ, according to research conducted at the University of Michigan.
The Sum and Product Puzzle, also known as the Impossible Puzzle because it seems to lack sufficient information for a solution, is a logic puzzle. It was first published in 1969 by Hans Freudenthal, and the name Impossible Puzzle was coined by Martin Gardner.
A 1,000-piece puzzle has a solving time range of 5 to 12 hours and an average solving time of 9 hours. This kind of time of time is our preference. It's great for leaving out on the table and chipping away at over a week or two.
But however Bitcoin evolves, no new bitcoins will be released after the 21-million coin limit is reached. Reaching this supply limit is likely to have the most significant impact on Bitcoin miners, but it's possible that Bitcoin investors could also experience adverse effects.
Printed cash can be prone to counterfeiting. Cryptocurrencies are designed to avoid counterfeiting, thanks to the complex network of computers that record and verify each transaction. By storing crypto transactions on a public, immutable blockchain, they cannot be changed or deleted, and everyone can see them.
Using J2TX, an app that is perfectly legal and available on the App Store and Google Play, you can harness the power of cloud computing to facilitate your cryptocurrency mining efforts. This app allows you to create a profile on a cloud service and request a specific amount of processing power for a monthly fee.
To compute r = n * b mod M: First set t to be the largest power of two such that t is less than or equal to n, and set r = 1. Then perform: A: If n is greater than or equal to t, set r = b + r mod M, and set n = n – t; else set t = t / 2.
The equation of exchange: M * V = P * Y[1] tells us that if the amount of money supply, M, (i.e. the coin supply) is constant, and the velocity of money is relatively constant, then an increase in demands for goods (Y), will cause a decrease in the price (P), price deflation.
Bitcoin uses the SHA-256 hashing algorithm to encrypt the data stored in the blocks on the blockchain. Simply put, transaction data stored in a block is encrypted into a 256-bit hexadecimal number. That number contains all of the transaction data and information linked to the blocks before that block.
To do this, let's use some analogies: Bitcoin is gold. Like gold, Bitcoin has a fixed supply in the world but an inflating schedule of circulating supply as it is mined from the earth. It has no intrinsic value, but it has hard properties, thus making it a store of value.
A Google Doc is a simple analogy for understanding blockchain technology. When we make a document and share it with a group of people, it is distributed rather than copied or transferred. This creates a decentralized distribution chain in which everyone has simultaneous access to the document.
For every transaction input, a bitcoin mining software generates a unique cryptographic hash puzzle that is difficult to decode. The software then groups the number of transactions required to form a block into a Merkle tree.
Working on a puzzle reinforces connections between brain cells, improves mental speed and is an effective way to improve short-term memory. Puzzles increase the production of dopamine, a chemical that regulates mood, memory, and concentration. Dopamine is released with every success as we solve the puzzle.
The Rubik's Cube, originally called the "Magic Cube" is a a 3-D mechanical twisty puzzle invented and licensed by Hungarian sculptor and professor of architecture Erno Rubik in 1974.
For an initial configuration, the fifteen puzzle is solvable when the parity of the permutation for all the blocks and the parity of the taxicab distance between the empty block and the bottom right corner of the grid are both even, or are both odd. The puzzle cannot be solved if one is even and the other is odd.
Even though dying from a shark attack is rare, your chances of winning the lottery are even rarer. According to the International Shark Attack File, your odds of dying from a “Jaws” moment is 1 in 3.7 million.
That password, however, was written on a piece of paper and sadly lost. The 7,002 Bitcoin are now worth more than $232 million and Thomas has just two attempts left to guess the password before it's encrypted and lost forever.
For his efforts, a bitcoin enthusiast awarded him 7,002 bitcoins. Later that year, he lost the password to his IronKey, the USB hard drive that contains the digital wallet that holds his bitcoins. Since then, the currency's value has skyrocketed, and Thomas' holdings are worth $220 million US ($321 million Cdn.)
Statutes that Authorize Judicial Forfeiture of Cryptocurrencies. If the government believes that your property represents the proceeds traceable to criminal activity, then it might be seized and subject to forfeiture proceedings pursuant to 18 U.S.C.
This puzzle is not top tier quality. I would equate it to the quality of a dollar tree puzzle. With that in mind, the quality is NOT why you would buy this. You buy it to gamble.
Hand-painted limited editions run from $3500-7000, and an 8-foot long masterpiece for $15,000 made Guinness World Records as the world's priciest puzzle.
Yes – You can make money by selling your old, finished, or unfinished jigsaw puzzles that are taking up space in your room. You can try selling them to family or friends as they may have been eyeing them.
The letters that are most commonly found at the beginning of words are t, a, o, d, and w. The letters that are most commonly found at the end of words are e, s, d, and t.
This kind of code is extremely easy to crack. It can be solved with time by hand like a puzzle, starting with guessing letters for shorter words. It is extremely easy to solve with a computer, using frequency analysis of different letters.
Cryptographic principles are the fundamental concepts and techniques that are used in the field of cryptography to secure communication and protect data. These principles include confidentiality, integrity, authentication, non-repudiation, and key management.
ROT13 ("rotate by 13 places", sometimes hyphenated ROT-13) is a simple letter substitution cipher that replaces a letter with the 13th letter after it in the latin alphabet. ROT13 is a special case of the Caesar cipher which was developed in ancient Rome.
A secret code, or cipher, is simply a substitution of one letter in an alphabet for another letter or number. I could say, for example, that instead of typing the letter E I will type the letter F instead. So house becomes housf. Another type of secret code transposes, or changes, the order of letters in a message.
Failure to handle key management properly is, hands down, the most common way that sensitive data ends up in the hands of hackers even if it was encrypted correctly.
How The #BitcoinButton Game Works. The rules of the game are really simple — be the last to click the button and you can win one Bitcoin. The game will start when the number of registered players hits 50,000.
The problem that miners solve to earn Bitcoin is to partially invert the SHA-256 hash function. SHA-256 is designed to be a one-way function, which takes any data and converts it into a 256-bit integer.
Play-to-earn games allow you to earn cryptocurrencies and NFTs by playing them. Most are based on blockchain technology and built on platforms such as Ethereum. The cryptos and NFTs earned in the game are owned by the player, who can sell them and make a profit.
What is the Bitcoin Button Game? The Bitcoin Button Game is a strategy game, where the last person to click the Bitcoin Button before the timer ends will win 1 bitcoin (BTC). The game starts when the number of registered players reaches 50,000. The 60-second timer will begin to countdown.
Answer: The best ways to earn free bitcoins include shopping rewards with credit cards, but you can also try airdrops, referral bonuses, playing games, and participating in trading competitions if you are an expert or beginner trader.
Bitcoins are still only accepted by a very small group of online merchants. This makes it unfeasible to completely rely on Bitcoins as a currency. There is also a possibility that governments might force merchants to not use Bitcoins to ensure that users' transactions can be tracked.
The research report put together by Ark Invest sees Bitcoin hitting price targets in 2030 of $258,500 in the bearish forecast, $682,000 in the average market and $1.48 million in a bullish market.
This is the real-time data fetched from our partnered price aggregators. At the moment, you are looking at the conversion of 200 BTC when 1 BTC is valued at 26,736 USD.
