Decode the Chain
Three blocks. Each one is locked with a different scheme, and each opens the next. Solve all three to read what the ledger kept. Spelling matters, spacing and case do not. Your progress is saved on this device.
Block 1 · the key is the war
A Vigenere cipher. The key is the name of the war these stories belong to.
VPT JLRKV GLQVOJTYW
Hint
The series is The Cipher Wars. Use that one word as the key, repeat it across the letters, and shift each letter back.
Decoded.
Block 2 · the ledger speaks in bytes
No key this time. Each pair below is one byte of ASCII. Read the bytes.
74 72 75 73 74 20 74 68 65 20 6D 61 74 68
Hint
These are hexadecimal byte values. Convert each pair to its character (for example 74 is "t").
Decoded.
Block 3 · one more block
The last block is base64 encoded. Decode it.
ZXZlcnkgYmxvY2sgaXMgYSB3aXRuZXNz
Hint
This is standard base64. Any base64 decoder, or a few minutes by hand, turns it back into text.
Decoded.
All three blocks clear
Three blocks, one truth: nothing on the chain is ever really gone. You read them the way he did, one block at a time, trusting the math more than the people.
The next fragments go only to the early reader list, with the first chapter and the notes behind the story.
