Layer 2 scenario practice

Separate immediate feedback, publication, settlement and exit rights.

LET’S PICTURE IT

Follow one fictional transfer across a layered system and label what evidence supports each stage.

SEE IT FOR YOURSELF

The first toy block records Maya sending Leo three units. A1 is an illustrative fingerprint label, not a real cryptographic digest.

Animated local teaching model. No wallet, RPC or live blockchain data. Some labels and hashes are abbreviated for readability.

Scenario: quick acknowledgment

A sequencer says a request was accepted. That is useful feedback but not automatically proof that its data is published or its state transition has settled on Ethereum.

Scenario: a valid proof

A verifier accepts a proof for specified state inputs and outputs. Ask whether the intended rules were encoded and whether users can obtain the required data. Correctness and availability remain distinct.

Scenario: a fast bridge

A service supplies destination assets quickly using its liquidity. That can introduce a different route from the canonical bridge, with its own dependencies and failure conditions.

Scenario: a familiar address

The same address appears on two networks with different balances. This is normal separate state, not proof of a broken unit conversion. A network switch does not itself transfer assets.
