Chamber I

The Legend

Every treasure begins with a story. This one is true, and you can verify every word of it. Watch the first part of The Legendary Treasure of Satoshi Nakamoto. Listen for who Satoshi really was, what he solved, and what he left behind. The vault will ask.

Chamber II

The Mine

New bitcoins aren’t printed. They’re mined. Computers all over the world race to solve a puzzle that takes no skill, only brute force: find a magic number, the nonce, that makes the block’s fingerprint (its hash) start with a run of zeros. You can’t aim for it. You roll the dice, billions of times a second, until you get lucky. Whoever lands it first mines the block and earns brand-new bitcoin. Try it: mine one block to continue.

But a block isn’t empty. It’s a bundle of real payments waiting to be confirmed: Maya paying a café, a shop paying its supplier, someone sending money to family. The miner gathers up these pending transactions, stacks them together, adds one more that pays themselves the block reward, and hashes the whole stack. Win the hash, and every payment in it becomes final, forever, written into the chain that no one can rewrite. That’s the real job: miners don’t just make coins, they settle everyone’s payments.

Chamber III

What Is Money?

Part two asks a question that sounds simple and turns out to be enormous: what is money, really? Bitcoin lets you see money stripped of governments and banks, in its purest form. Watch, and pay attention to the strange little story about a banana.

Chamber IV

The Real Treasure

The last part of the film reveals the twist. Satoshi’s million coins, sitting forever in plain sight, untouchable, are not actually the treasure. They are a monument. The real treasure is something only you can hold. Watch to the end, then tell the vault what it is.

Chamber V

The Hunt

Now you need somewhere to keep your treasure that no website, no app, and no thief can reach. Years ago, your mum was given a small device built for exactly this, a Ledger Nano S, a hardware wallet. She never used it, so it is still somewhere in your house, asleep in a drawer, probably still in the little white box below. Go and find it.

Chamber VI

Become Your Own Bank

Time to wake the device. The original Nano S plugs in with a small USB cable, so you’ll need a laptop or computer for this part. Follow each step in order. Take your time. This is the moment you stop trusting a bank with your money and start trusting yourself.

1. Install Ledger Live

   On your computer, go to ledger.com/ledger-live and download the official app. Only ever use that address. Open it and choose to set up a new device.

2. Plug in & power on

   Connect the Nano S with its cable. The screen lights up. Press the right button to move through the welcome. If it asks for a PIN you don’t know, it was set up before. Enter a wrong PIN three times to safely wipe it, then start fresh, the coins are only ever as safe as a brand-new setup.

3. Choose “Set up as new device”

   Pick a PIN of 4 to 8 digits. Use the two buttons to choose each digit; press both together to confirm. This PIN guards the physical device. Don’t use 1234 or your birthday.

4. Write down the 24 words

   The device shows a 24-word recovery phrase, one word at a time, on its own screen. These words are your money. Write all 24, in order, by hand, on one of the paper cards in the box. You’ll lock them away properly in the next chamber.

   Never type these words into a phone or computer. Never photograph them. Never put them in cloud, email, or a notes app. Anyone who sees them can take everything.

5. Confirm the words

   The device asks you to pick a few of the words back, to prove you wrote them down. Do it. Then it says “Your device is ready.”

6. Install the Bitcoin app

   In Ledger Live open My Ledger, search Bitcoin, and install it. (The old Nano S has little room, but the Bitcoin app fits with space to spare.)

Chamber VII

The Master Key

Those 24 words are the only key that can rebuild your wallet if the device is ever lost, stolen, or broken. So they have to survive water, fire, time, and prying eyes, without ever touching the internet. Tonight you’ll build their hiding place from things you already have.

1. Check your handwriting

   Read your 24 words back against the device once more. One wrong word, and the key won’t turn. Block capitals are easiest to trust later.

2. Build a waterproof vessel

   Fold the card so no words show. Seal it in a zip-lock bag, push the air out, then a second bag around that. Drop it into something rigid and sealable: a screw-top jar, a lidded food tub, a pill bottle, a lunchbox. Tape the lid. Water is the enemy; you’ve just beaten it.

3. Make a second copy

   Write the words a second time on the spare card and hide it somewhere completely different from the first. Two copies, two places. If one is lost or ruined, the other still opens the vault. One copy is a single point of failure.

4. Hide them well

   Not in an obvious box marked “bitcoin.” Somewhere you’ll remember in ten years but a burglar wouldn’t find in ten minutes. Taped under a drawer, inside a boring tin, buried in the garden in its jar. Tell no one where. Not even me.

Chamber VIII

The Claim

The vault is yours. The key is hidden. All that’s left is to open a door for the treasure to arrive through, your very own Bitcoin address. You can hand it to anyone, in public, forever; it only lets people send to you, never take.

1. Add a Bitcoin account

   In Ledger Live: Accounts → Add account → Bitcoin. When asked, choose Native SegWit. Your account appears.

2. Show a receive address

   Open the account, click Receive, open the Bitcoin app on the device when prompted.

3. Verify it on the device

   Ledger Live shows an address starting bc1…. The same address appears on the device’s own screen. Check they match, then press both buttons to approve. This is the one check that defeats every clever virus.

4. Copy it here

   Copy the verified bc1… address and paste it below. It’s safe to share; it’s only a letterbox.
