Universe from Bitcoin block #1,699
Observers possible可能诞生观察者
Grade S · observers possible

Galaxies, stars, planets and chemistry all exist, and stars live long enough for complex processes to unfold. Under this model the conditions for observers are met. Only a few percent of blocks get this far.

| Planck constant h | 6.239×10⁻³⁴ J·s | 0.942× ours |
| Elementary charge e | 1.460×10⁻¹⁹ C | 0.911× ours |
| Gravitational constant G | 1.902×10⁻¹⁰ m³kg⁻¹s⁻² | 2.850× ours |
| Gravitational coupling αG | 3.407× ours |
Constants are reported in an external frame. Only α and αG are observable from inside the universe; c, h, e and G can be rescaled without changing what its inhabitants could measure.
Not minted yet — the first confirmed transaction owns it.
On-chain, this universe lives in the same MirrorUniverse contract on BNB Chain as every BNBBANG universe, with blockHash = the Bitcoin block hash and blockNumber = its Bitcoin height (1,699). The contract’s verified flag is false for every Bitcoin-origin universe: BNB Chain cannot look up a Bitcoin hash, so the flag simply does not apply — that is the expected state, not an error. Anyone can confirm the origin by fetching this height from any Bitcoin node or explorer and comparing the hash.
