Room 3

Answer 1

If Bitcoin isn't stored inside a wallet, then what exactly does a Bitcoin wallet store?
Explain the role of a wallet in your own words.

A wallet doesn't hold Bitcoin, same way a banking app doesn't hold cash. The coins exist as entries on the bitcoin blockchain. What the wallet actually stores is your private keys which is the secret key that lets you sign and move the coins. So it's like a keychain rather than a purse.

Answer 2

Three objects appear on the pedestal. A Private Key,  A Public Key, A Bitcoin Address

Explain:
   •   What each one is.

   •   How they are related.

   •   Why confusing them could lead to losing your Bitcoin.

Imagine you're explaining it to someone who has never used Bitcoin before.

Private key is a secret random number. Whoever has it owns the coins and can send it.
Public key is made from the private key with one way math, people use it to check your signatures.
Address is a hash or fingerprint of the public key, that's what you hand out to get paid.

From private key software makes public key and from public key software makes bitcoin address.

The danger is they all look like gibberish to a beginner. Sharing your address is fine, that's its job. Paste your private key somewhere thinking it's your address, Bitcoins will be stolen. The opposite mistake also exist- if you save the address instead of the private key, and the private key is lost, the money just sits there forever.

Answer 3

What are these words?
Answer the following:
   1.   What is this list called?

   2.   Why is it important?

   3.   Can these words recreate a wallet?

   4.   Should you ever share them with another person? Why or why not?


These are first 12 words of the BIP39 dictionary. A seed phrase is 12/24 words picked randomly from the full list of 2048.

It is called recovery phrase / seed phrase
It's your private key in word form. Every private key and address in your wallet is derived from it.
The words can recreate the wallet. Type it into any compatible wallet and everything comes back
Never share it. Whoever has the words has the coins, they can restore your wallet on their phone and send everything to themselves.

Answer 4

A note is pinned to one of the safes.
It reads:
"I lost my phone, but luckily I took a screenshot of my recovery phrase and saved it to my cloud drive."
The safe immediately flashes ACCESS DENIED.
Question:
Identify every security mistake made in this sentence.
How could the person have protected their Bitcoin more safely?

Screenshots aren't safe. Malware scans photo galleries looking for grids of 12 words
The cloud drive means it now lives on someone else's server (which could  be hacked) behind an email and password, so 256-bit security got downgraded to password level security
Screenshots also sync themselves into backups and trash folders, so the phrase probably exists in more places than the owner even knows.

The correct way is to write it by hand on paper (or metal), keep it offline somewhere safe, maybe two places, and do one test restore so you know it actually works. For serious money, hardware wallet.

Final Challenge Answer

A friend has just bought their first Bitcoin.
They ask you:
"What's the single most important thing I should never do if I want to keep my Bitcoin safe?"
Write your answer as if you're giving real advice.
Support it with reasoning.

I'd tell the friend never type or share your recovery phrase anywhere except your own wallet. Not to "support", not on a site that wants to "verify" your wallet, not in a photo. Nowhere, ever.
There's no bank behind you anymore. Nobody can freeze your money, but it also means no fraud department, no password reset. Owning bitcoin is just knowing a secret, and basically every beginner horror story is that secret leaking somehow: fake support agents, phishing sites, screenshots. And if your coins sit on an exchange you hold zero keys anyway, just an IOU. Not your keys, not your coins.

Answer to Bonus

James Howells. In 2013 he cleaned out his office and threw away the wrong hard drive holding keys to about 8,000 BTC he mined in 2009. It's been buried in a landfill. He spent over a decade trying to get permission to dig it up, even offered to buy the whole landfill, and a court killed the case in 2025.

Lesson: Always keep a backup. Know exactly which device or where your keys live on, back them up before you clean anything.

These are my answers for room 2:

Answer 1


SHA-256 means, Secure Hash Algorithm 256-bit, this last part, 256-bit means that everything that comes out from the SHA-256 function will always be 256 bits. It doesn’t matter the size of the thing you want to hash, it will always give you a 256 bits hash which typically is a 64 character hexadecimal string. It doesn’t matter if it is a word, a book, or whatever the size of the thing you want to hash, the result will always be 256 bits.

Now, why is this SHA-256 important for Bitcoin? Because every single change in the information before hashing changes the hash. Let’s say you want to hash this “roses are red” it gives you 64 characters “134af2…bc45” but if you change something in that line before hashing, for example “roses, are red”, it will give you a completely different hash with 64 different characters. This is so important for transactions integrity, because it’s not the same to say person A sends 10 BTC to person B, than person A sends 0.1 BTC to person B, both transactions are between the same addresses but they don’t have the same amount which will give 2 different hashes. And if one miner receives a hash that is different from the one of the rest of the network it will alert them.

That’s one way where Bitcoin uses SHA-256, the transaction IDs, the other place is in the Merkle Trees that are transactions grouped and hashed together. This makes it more efficient since you don’t have to download the entire block to know which transactions are inside a block.


Answer 2

ECDSA means Elliptic Curve Digital Signature Algorithm, which is a cryptographic algorithm used to securely create and verify digital signatures. To make it simple, this is the thing that creates the 2 keys you have in your wallet, the private key (the one only you know) and the public key (the one that everyone knows).

Now, why does Bitcoin use digital signatures? The most important reason is for security. Your signature is tied to each transaction you make, and each address you have. So, let’s say someone tries to alter a transaction you made, let’s say you send 1 BTC and someone wants to change it to 10 BTC, they won’t be able to do that because just changing the BTC amount in the transaction creates a different transaction that won’t match with your key and makes the signature invalid.

So, although all transactions, addresses, and balances are public, no one can move BTC from one address to another without having the private key. That’s why signatures are so important for the chain, since without them anyone could get your BTC, there wouldn’t bet be proof of ownership or authentication.

Answer 3

This

Code:

1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa

is a public address, but it’s not just any address, it is the first Bitcoin address created on January 3, 2009, the one that holds 50 BTC.

Now, remember that we talked about SHA-256, your address is a hashed version of your public key. Your uncompressed public key has 130 characters and it is reduced for your address to 26 - 62 characters long. This helps to make your address more readable, it also helps to make it easier to find errors in the addresses, and of course for security since your public key is only exposed once you make a transaction

Answer 4

Remember that we talked about Merkle trees when we talked about SHA-256, the diagram is exactly that, a representation of a Merkle tree. So, the tree is built from the bottom, you have the root node, then the intermediate node, and at the end the leaf nodes. The root is the one that secures the entire tree, this means that if something in the tree changes it will give you a different root, that way you can verify the data.

Now, why is the tree useful? Because it securely summarizes entire blocks of data, and allows users to quickly and efficiently verify whether something is inside a massive dataset without needing to download or process all the data.

So, taking this to Bitcoin, it helps with transaction verification because it summarizes thousands of transactions into a single hash. So, for example, the entire chain is around 755 GB to 861 GB, imagine having to download all that just to confirm every single transaction. The tree makes it easier since it groups a lot of transactions and you just have to confirm if the root is the same.


Answer for Final Challenge

I think that removing ECDSA would be the worst. Because if you can’t proof that you own your money anyone could take it, it is not safe at all, and everyone would be stealing from everyone which would make the chain collapse. Well, I doubt anyone would ever want to participate in something that won’t secure their assets so maybe the chain wouldn’t even be launched without having ECDSA.

ROOM 4

Answer 1

This is Hal Finney. On January 12, 2009, Satoshi Nakamoto sent Hal Finney the first Bitcoin transaction (10 BTC).

Bitcoin first emerged as an idea, then as a whitepaper, and finally as code.

But after this transaction, the Bitcoin network was created (albeit with only two nodes). But these weren't just two computers, but two people! Hal Finney acted as a supporter and ally of Satoshi Nakamoto. He launched the software client, tested mining, and confirmed the correct operation of the Bitcoin protocol.

So, not only did the Bitcoin network emerge, but the Bitcoin community also emerged at this moment.

Answer 2

The purchase was made by Laszlo Hanyecz, a Florida programmer and one of the first Bitcoin miners. On May 22, 2010, he exchanged 10,000 BTC for two pizzas (apparently he was very hungry while working on the code 😃). A Bitcointalk.org forum user with the nickname "jercos" arranged for Laszlo to grab a bite. He ordered two pizzas and arranged for them to be delivered to Laszlo's home.

This event is celebrated every year for a number of reasons.

First, it marks the first time goods were paid for on the Bitcoin network.

Second, it marks the first time Bitcoin was fully used as money (governments and institutional players are very reluctant to call Bitcoin money, instead using terms like "digital asset," "property," and so on. But the truth is, Bitcoin is, first and foremost, global, decentralized money).

Third, this is the first recorded exchange rate between Bitcoin and the US dollar. After all, we know the price of two pizzas in fiat.

Fourth, selling two pizzas for 10,000 BTC is mind-blowing! It's already become a meme.

Fifth, celebrating Bitcoin-related holidays is always fun! For example, the Bitcointalk.org forum always holds a pizza-making contest in May!

Answer 3

This is Gavin Andresen. He became the lead developer of Bitcoin Core and the successor to Satoshi Nakamoto. He also created the first Bitcoin faucet and gave away 19,700 of his bitcoins to others. On the Bitcointalk.org forum, he actively answered questions from newcomers and patiently explained the technical nuances of Bitcoin.

People are grateful to Gavin Andresen for his contribution to Bitcoin's development!

Answer 4

Several people received a letter from Satoshi Nakamoto. These were people well versed in cryptography and dreaming of a free internet. One of them was Hal Finney. It was he who tweeted "Running Bitcoin" on January 11, 2009.

However, since the first portrait depicts Hal Finney, the fourth likely depicts someone else. It could be Dustin Trammell, an experienced cybersecurity expert who became fascinated with the idea of ​​Bitcoin and began actively mining and testing it back in January 2009. The letter (or rather letters) were of historical significance, as they marked the beginning of the Bitcoin network's creation. Satoshi Nakamoto reached out to the people, and they responded!

Answer 5

This is Satoshi Nakamoto. Bitcoin's founder remained anonymous. I believe Satoshi Nakamoto wanted to create something great that would develop and function without his involvement. Perhaps he was inspired by the process of biological evolution of living things. Perhaps he was inspired by the Bible and divine creation (although he didn't come across as a religious person).

In any case, he tried to minimize human influence on Bitcoin's functioning. Bitcoin was designed to operate in an untrusted environment, and humans are weak... People can be intimidated, bribed, and seduced. Satoshi Nakamoto was betting on decentralization. If he had become a public figure, the Bitcoin system would have had a single point of failure. This would have been enough to attack and discredit Satoshi Nakamoto, which would have allowed them to attack and discredit Bitcoin itself. Perhaps Satoshi Nakamoto also understood that any great invention is a myth, that is, a well-told story.  The story of the anonymous founder of Bitcoin who created Bitcoin and then disappeared is a fascinating, mysterious and intriguing story that adds value to Bitcoin.

Final challenge

The first person on Mount Rushmore is Adam Back. He is the creator of the Proof-of-Work consensus algorithm and one of the most staunch proponents of Bitcoin maximalism. When Satoshi Nakamoto created Bitcoin, he closely studied Adam Back's work. They can be considered like-minded individuals... Adam Back continues to make significant contributions to Bitcoin's development: he is an SEO specialist at Blockstream and is involved in all significant projects aimed at further developing the world's first cryptocurrency. He advocates for preserving Bitcoin's fundamental value while simultaneously implementing innovations at the Layer 2 level.

The second face carved into the mountain is Satoshi Nakamoto himself (he's wearing a mask, as he's managed to maintain his anonymity and privacy). He created Bitcoin, the first cryptocurrency. Some say Satoshi Nakamoto is a pseudonym for a group of people. I don't believe that. I think Satoshi Nakamoto is one person. He valued freedom and independence. He managed to change the world.

The third person whose face is carved into the mountain is Hal Finney. He was the first to support Satoshi Nakamoto's idea. As a result, the Bitcoin network was created from two computers and the Bitcoin community from two people. If he hadn't supported Satoshi then, Bitcoin as we know it might never have existed!

Bonus challenge

In January 2009, when Bitcoin was still worthless and merely a technological experiment, Hal Finney sent a letter to a cyberpunk mailing list. In it, he calculated the potential price of Bitcoin if it became the world's reserve currency ($10,000,000).

So what did Hal Finney do? Essentially, he created a "thought virus"! It activated both human imagination and human greed. It's reminiscent of Isaac Asimov's "Foundation." It was from this letter that the "HODL" investment strategy emerged, as well as interest in Bitcoin as an investment asset rather than a means of payment, the use of ASIC miners for Bitcoin mining, and Michael Saylor's financial scheme.  Human imagination and human greed, in my opinion, are both wonderful and terrible things... Perhaps Hal Finney was wrong when he told people about Bitcoin's potential financial value instead of emphasizing its importance as a tool for achieving financial freedom and independence... Perhaps not. I don't have a definitive answer to that question.

These are my answers for room 3 (Sorry I'm a week behind)

- Challenge 1 – What Is a Wallet?

First we need to understand that Bitcoin is stored in the blockchain, it is not stored in a wallet. It doesn’t matter the type of wallet you have, your wallet does not have your tokens. So every wallet stores your keys, both your private and public keys, and use that information to prove ownership of your funds, get your transaction history, and calculate your balance.

- Challenge 2 – The Three Keys


Your private key is your signature, it is the most important thing because it is the thing that proves you are the owner of those tokens. And is the thing that authorizes a transaction when you are sending your tokens.

Your public key comes from your private key, it is used to create your address and it is used to verify the transactions by verifying your signature.

Your address is what you use to send and receive your tokens. An address comes from your public key and it’s an unique identifier, there are no duplicate addresses which means that if you send tokens to the wrong address it will be lost.

Now, as you can see they relate because a private key creates the public key which then creates your address. And you should never confuse them. Especially your private key, because if you accidentally reveal your private key, someone can use it to transfer all the tokens you have.

Challenge 3 – The Recovery Phrase

That’s called a seed phrase, and it is a sequence of 12 to 24 random words. Most wallets use just 12 words. And your seed phrase is like a back up of your master key, giving you a way to recover your wallet. You should never share your seed phrase since they could use it to restore your wallet and transfer all your funds.


Challenge 4 – The Mistake

- They have a hot wallet in an insecure device, they took a screenshot of the seed phrase, and they saved it in their cloud. Both their phone and their cloud can be hacked, so their seed phrase and wallet are not secure

- The best way is to have a cold wallet, especially if they have a big amount of BTC. The second thing is to write down the seed phrase and store it in a safe place. And only use hot wallets for small amounts


Final Challenge – You Are the Bank

The most important thing would be to never share your seed phrase and your private key, the second thing would be to write them down and keep them stored in a safe place. And lastly if you are going to use a hot wallet you need a device that you use only for that purpose.

Keep in mind that all devices are hackable, but having an isolated device that you only use for transactions can minimize that risk. Obviously, having a cold wallet would be best, especially if you hold large amounts of BTC. Think of it this way: your hot wallet would be like having cash in your pocket, while your cold wallet would be like keeping your BTC in a vault.

My answers for room 4

Exhibit 1

The second person to receive a Bitcoin transaction was Hal Finney, and he received 10 BTC in block 170 on January 12, 2009. This is important because Satoshi sent the transaction to test payments, and Hal was the second person to download and run the Bitcoin code. So he helped debug the network.

Exhibit 2

The first time someone used BTC to pay for something was on May 22, 2010. On that day Laszlo Hanyecz paid 10,000 BTC for 2 pizzas, and it is known as the Bitcoin pizza day. But what people don't know is that Laszlo posted the offer on a Bitcoin forum, and someone accepted that offer and paid the pizza with a credit card. So, technically he paid someone who bought the pizza with a credit card, he didn't pay directly to the pizza restaurant for the pizza.

It is still celebrated because it proved that the code can be used to get physical goods, it is not just code in a computer anymore, it became evidence of the concept that BTC can be used as money.

Exhibit 3

Gavin Andresen became Bitcoins lead developer after Satoshi stepped away. He is the one that created the first Bitcoin faucet, and co-funded the Bitcoin Foundation. The faucet was a huge step to get early user adoption, and the foundation has been crucial to keep Bitcoin's image and development. Oh, he also handled the central code repository, making all the new updates.

Exhibit 4

One of the first people who received an email from Satoshi about Bitcoin was Adam Back, the inventor of Hashcash. This is important because Satoshi talked with him before releasing the whitepaper, that's why Hashcash is cited in it as the blueprint for the mining mechanism. And this helped refine the code, and it also helped as evidence of everything that was happening before Bitcoin's launch.

Exhibit 5

I will go with Satoshi, and I'll go with privacy. If he were to expose his identity, he would no longer be able to live a "normal" life, and I also believe that at the time there would have been some kind of legal consequences since Bitcoin wasn't so accepted back then. Now he might not have as many legal problems, but a couple of years ago there certainly would have been some kind of issue

Final Challenge – Build Your Bitcoin Mount Rushmore

I will go with Adam Back, Satoshi, and the Bitcoin Foundation, or if it's just one person Gavin Andresen.

Adam Back represents the base, the foundation, without his work Satoshi would not have been inspired to make his code and improve the way BTC is mined.

Satoshi of course, because he came with the idea, worked on it, published it and let it running for the rest of us to use it.

The Bitcoin Foundation because thanks to all the people who worked hard to standardize, protect, and promote the use of Bitcoin, we can continue using it and it has become legally accepted in some countries
