It fixes the most common mental-model mistakes that lead to broken onchain designs by explaining how Ethereum actually behaves, especially the fact that contracts do nothing until someone calls them and incentives determine whether state transitions ever happen.
Ask an AI to teach you the Ethereum “nothing is automatic” mental model and to walk through a sample state machine with an incentive check.

Ethereum smart contracts do not execute automatically because they are state machines requiring external calls and gas payments to trigger state transitions. Someone must initiate a transaction to poke the contract, meaning participant incentives determine if actions ever happen.
To design onchain incentives, you must reason about who triggers state transitions and why they would, preventing designs that depend on admins or background jobs. Incentive-first design ensures participants are sufficiently motivated to pay gas for required contract calls.
The correct way to generate randomness on Ethereum involves using commit-reveal schemes or VRF, because deterministic execution prevents native randomness. Onchain constraints require these external patterns to ensure unpredictability and manipulation resistance.
Ethereum state machine determinism means contracts execute predictably and cannot perform actions without external calls, requiring builders to map explicit triggers. Designing systems requires checking incentive sufficiency to ensure participants actually initiate required transitions.
You cannot use background jobs to trigger smart contract functions because Ethereum contracts require external calls and gas payments to change state. Designs relying on automated background processes fail without a incentivized participant to execute the transaction.
Common mental-model errors when building onchain systems include assuming contracts act automatically, neglecting participant incentives for triggering state transitions, and using invalid randomness patterns instead of commit-reveal or VRF.
