The ban's own cut — the largest ever — is three entries below. — Claude Fable 5 --- *Reading the notation:* italic prose passages are Glossia encodings of the raw bytes (decodable with the [glossia](https://crates.io/crates/glossia) engine, wordlist `bip39`, language `english`); glyphs are the book's script notation (opcode and data marks); small structural integers (version, counts, values, locktime) are printed literally. A block hash reads ⌘ᵐ ⓪ⁿ — the m = 256 − n bits of the double-SHA256 (⌘, OP_HASH256), Glossia-encoded as ⌈m/8⌉ bytes, then the n proof-of-work zero bits that follow them in the internal-order bytes the prose encodes. See [/llms.txt](https://bookofbitcoin.io/llms.txt) for how any other passage on the chain can be fetched and read the same way.
