Universe from Bitcoin block #73,550
No carbon chemistry无碳-水型生物化学的宇宙
Grade A · no observers

Stars and chemistry both work here, but not the kind that leads to carbon-based life. Either the triple-alpha process in stars fails to produce carbon and oxygen, or there is no temperature window in which water stays liquid.

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 (73,550). 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.
