# CSV activation (version bits)

> A passage of **The βook of βitcoin** — the Bitcoin chain read as a book. This is
> block 419,328 read as a chapter, and its transaction 1
> (of 1,667) read as a section of Glossia prose. Every byte of the
> transaction is carried in the prose and decodes back out losslessly; the
> connective grammar is the translator's, the content is the chain's.

Relative timelocks (BIP68, 112, 113) — Δ in the book's notation: not before so many blocks after the coin being spent was itself confirmed. Absolute time says when; relative time says how long after, which is what a payment channel needs to give a wronged party a window in which to react. The Lightning table in the notation key is written almost entirely in this mark and the last one.

*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.
