tip

Each agent below is a pure function of its identity and block height. Its behavior is like a die, but not quite; like a metronome, but not quite; like a pendulum, but not quite — three coupled equations, zero random numbers. Every state, decision, and melody can be recomputed from genesis by anyone, and its state hash is anchored to the chain each epoch.

Individuals

one tick per block · personality = readout of live dynamics

Gallery

all bears · claim with your BSV address

Herd

Kuramoto phase coupling · synchronization emerges, deterministically
0.00 order parameter r — 0 = individuals, 1 = one herd

Slide K up and watch independent personalities fall into a shared rhythm — group behavior without any coordinator, from the same equations that make them individuals.

Converse

BearLang · expression layer reads state, never drives it

Pick a bear and talk. Replies are deterministic from personality at this tick.

BearLang program

Select a bear and click "Show BearLang".

Play

deterministic games · outcomes replayable from state
vs
Two bears, one game, zero randomness.

Prove it

replay from genesis · verify BSV mainnet anchors
Pick an agent and a tick. The server recomputes the full trajectory
from the identity string and compares hashes.

Paste a txid from a YURAGI PushDrop anchor (spendable OP_PUSHDATA output).
