## Commentary

> A reading of the record, not the record. The passage above is the chain's own

26 March 2020: the covid crash. Black Thursday, two weeks earlier, halved the price in a day, and the marginal miners shut down; this window recorded the exit.

*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 <prose> 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.
