This way, you can also become a threat to our democracy.Requirements:1. Paper 2. Pen or pencil 3. Dice or Coin 4. Calculator 5. Printed out copy of the BIP-0039 protocols word list from GitHub https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt 6. An analog computer, or hardware wallet.Collect this post for FREE on Zora Network (only 100 mints available)Connect WalletCollectStep 1:A. For a 12 word seed phrase, number your paper 1 through 12, skip a line & number it one through 12 again. B. Write out “1024, 512, 256, etc…” at the top columns of the paper as shown in the image below:Step 2:A. Roll dice (even numbers = 0, odd numbers = 1) or flip your coin (heads = 0, tails = 1) B. Record your roll on the paper. Begin at the “1” beneath “1024” & continue to roll and record under each column from left to right.Step 3:Once you have completed your rolls on the first row take every column where you recorded a “1” & add the number above it, then add the “+1” at the end of the row & write the number. In the image below 1 was recorded in 512, 128, 64 & 16. 512 + 128 + 64 + 16 + 1 = 721Step 4:Continue this process until you get to the final 4 spaces on the paper. Note: The 12th word to your seed is your “checksum” word. This word must be a mathematically compatible fit with your previous 11 words ensuring your seed can function with the BIP-0039 protocol.Step 5:A. Before we can find out the final checksum word we must first translate our binary digits to their corresponding BIP-0039 seed words. B. Open up the word list & write down the word associated with each number that you wrote down. Ex. (721 = foam)Step 6:Continue step 5 all the way to word 11.Step 7:A. To find the final checksum word we must first import our 11 words onto our hardware wallet. (For this example, I am using a COLDCARD wallet MK4 by Coinkite) B. Select “Import Existing” on device.Step 8:A. Select “12 words” on device. B. Enter all your words up to word 11. Step 9:A. To find your final checksum word, add up your 1s and 0s in your 12th row. B. Get out your BIP-0039 word list & start at word “801” (the sum of your 7 rolls) for this example.Step 10:Your checksum could be any word between 801 & 816 so we will have to guess each one for the 12th word by inputting it on the device until the device confirms that we found a compatible checksum.Step 11:When you find your 12th word your device will confirm it’s a fit by applying the private key into a PubKey private key dataset that you can use to sign TX’s with the device, & broadcast to the internet without revealing sensitive data (like private key) through PSBT’s. The odds of someone else being able to guess your specific private key is 2048^12 You have better odds of picking out a specific atom on earth, than anyone has to crack that key. Adding a passphrase moves this from the realm of mathematical improbability & into impossibility. Generating a key completely offline is something all of us must know & teach for maximum security. We can’t trust generating this on any device, or application, etc which all represent potential attack vectors.
