CryptoKitties · interactive mechanism simulation

Gen0 auction drips new cats at a Dutch-declining price → players buy, own, and breed them (each breed lengthens that kitty's cooldown) → offspring and originals get listed on the marketplace for a fee → every action is a transaction on Ethereum, whose gas price rises with traffic. Edit the parameters, or replay the December 2017 congestion shock.

Illustrative simulation. Defaults mirror the researched CryptoKitties mechanism (Gen0 Dutch-clock drip, generative breeding with lengthening cooldowns, a ~3.75% marketplace fee), but the pacing, prices, and gas response are compressed and randomized for visualization — not live onchain data. The "Trigger congestion" button replays how December 2017's demand shock spiked gas and slowed the network. Part of The Onchain Experiment Atlas.
