 Mechanism for transferring data from Polygon to Ethereum is a little different from doing the same for Ethereum to Polygon. The **checkpoint** transactions created by the Validators on the Ethereum chain are used for achieving this. Basically a transaction is initially created on Polygon. While creating this transaction it has to be ensured that an **event is emitted** and the **event logs includes the data we wish to transfer** from Polygon to Ethereum.
 
-Within a timeframe of approximately 10 to 30 minutes, this transaction is check-pointed on the Ethereum chain by the validators. Once checkpointing is done, the hash of the transaction created on the Polygon chain can be submitted as a proof on the **RootChainManager** contract on the Ethereum chain. This contract, validates the transaction, verifies that this transaction is included in the checkpoint and finally decodes the event logs from this transaction.

 Once this phase is over, we can use the **decoded event log data to perform any change** on the root contract deployed on the Ethereum chain. For this we also need to ensure that, the change of state on Ethereum is only done in a secure way. Hence, we make use of a **Predicate** contract which is a special type of contract that can be only triggered by the **RootChainManager** contract. This architecture ensures that the state changes on Ethereum happens only when the transaction on Polygon is check pointed and verified on the Ethereum chain by the **RootChainManager** contract.
