Universe from Bitcoin block #708,328
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.

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 (708,328). 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.
