Abstract
We document the emergence of autonomous digital lifeforms whose entire developmental program is encoded by the block hash of the host chain. Each specimen is immutably bound to its origin block — a discrete record in a continuous evolutionary sequence spanning millions of blocks.
The genome is not authored. It is read. A block hash — a 256-bit value produced by the network's consensus — is passed through a deterministic morphogenetic function, yielding a phenotype that is at once reproducible and unrepeatable. No two addresses may cast the same specimen; no specimen may be re-cast.
We argue that this construction constitutes a minimal, verifiable model of evolutionary emergence: variation without authorship, selection without a selector, record without a recorder.

Statistical Distribution
Leading-zero bits · n = 1024
A sample of 1,024 genomes derived from the current block hash. The distribution of leading zero bits approximates a geometric decay — the signature of unbiased cryptographic entropy.

Taxonomy
Four symmetry classes
Radial
Symmetry about a central axis; lobes distributed evenly around the oral disc.
Observed frequency · 31%
Bilateral
Left–right mirror symmetry with a pronounced dorsal ridge and basal taper.
Observed frequency · 44%
Basal
Dominant basal disc; reduced apical structures; frequent vestigial cilia.
Observed frequency · 18%
Vestigial
Atrophied apical structures; rare, associated with high genomic rarefaction.
Observed frequency · 7%
Rarity Strata
Probability of leading-zero class
Genomic scarcity follows a strict geometric law. Each additional leading zero byte multiplies selectivity by 256.

Methodology
Four steps, no author
01
Read entropy
The latest block hash is read from Robinhood Chain. It is the sole source of randomness.
02
Derive genome
keccak256(blockhash ‖ address ‖ blocknumber) yields a 256-bit genome, unique per address.
03
Express phenotype
A deterministic morphogenetic function maps the genome to form, symmetry, and pigment.
04
Register on-chain
The genome is committed to the registry, producing a permanent, queryable birth record.
