Simulation, submission and accepted state updates are separate operations.
LET’S PICTURE IT
Reading a form, rehearsing its effect and submitting it for official processing are different steps.
SEE IT FOR YOURSELF
Receive, check and share across independent nodesStep 1 / 4
A node receives a proposed transaction or block-related message. Receipt is not the same as accepting its claims.
A node receives a proposed transaction or block-related message. Receipt is not the same as accepting its claims.The node checks the relevant authorization and protocol rules. Popularity does not make an invalid state transition valid.Valid candidate data can propagate to peers. Connections and timing differ, so there is no perfect simultaneous worldwide view.Peers validate under the same protocol rules. This illustration is about verification and propagation, not a complete proof-of-stake consensus algorithm.
Animated local teaching model. No wallet, RPC or live blockchain data. Some labels and hashes are abbreviated for readability.
A call can simulate execution
An eth_call-style query executes against a chosen state view and returns a result without committing its state changes to the chain. The sender and value context can still affect what the simulation does.
A submitted transaction needs authorization
A signed transaction can be broadcast for potential inclusion. Submission does not itself prove inclusion, success or finality. A hash returned by a provider identifies data rather than guaranteeing settlement.
View functions still execute code
A local getter call can avoid an onchain fee, while using the same code within a transaction consumes resources. The view label is a state-modification restriction, not a universal cost exemption.
Use the correct observation
Read a receipt for an included execution result and inspect chain context for settlement. Our tools stop at local computation and deliberately do not offer a send or wallet-connect flow.
QUICK CHECK · NO PRESSURE
Does eth_call persist its simulated storage changes to the chain?
It is a simulation query rather than a committed transaction.
