# BIP34 activation (v2)

- **previous block:** ⌘²⁰² Above achieve rally to horror per proof. Yes there get tribe. Grain see bullet to scene. The paddle is zero. A draft may see payment to our liquid due. Yes may imitate immune. Pay erode our budget stairs to advice. ⓪⁵⁴
  - hex: `0000000000000251b3834c8d5b9c041bfaa0fedb93c0f16099d0072ed6b629d6`

- **nonce:** η 2·5·31·37·216509

## § 1 — BIP34 activation (v2)

Transaction id, as prose: ⌘²⁵⁶ *Abandon may access to oppose. Lawsuit set purity for history. Element is valid to name. Old may throw cactus out shield for dream. Gym dice example to tool. Anxiety come glimpse out panic. Dune tenant to empower.*

- **version:** 1
- **input 1:** coinbase (∅ — no previous output; new coin)

From this chapter a coinbase must state the height of the block it sits in — the chain's first self-referential rule. It also ends the duplicate-coinbase problem structurally: two blocks at different heights can no longer write the same coinbase, so the accident BIP30 had to grandfather cannot recur.

*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.
