# The Third Halving

> A passage of **The βook of βitcoin** — the Bitcoin chain read as a book. This is
> block 630,000 read as a chapter, and its transaction 1
> (of 3,134) 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.

6.25 coins from this block on, 11 May 2020, shown in the coinbase's output value. The block opens Volume IV. Same arithmetic as the two halvings before it: 630,000 is the third multiple of 210,000, so the amount halved — no decision was taken in 2020 for a node to check.

*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.
