Data Availability

Rollups are L2s that periodically post state commitments to Ethereum. These commitments are validated by either Validity Proofs or are accepted optimistically and can be challenged via Fraud Proof mechanism within a certain fraud proof window. Additionally L2 data is also posted to Ethereum, hence there are no additional trust assumptions introduced.

This data can be received from an aggregator when depositing or transferring funds, or from senders when receiving funds. The protocol ensures that for a deposit or transfer to be accepted by the protocol, the user must confirm the collection of data from the aggregator.	Users self attest the collection of data to the aggregator when depositing or transferring funds, and the protocol verifies the signatures before accepting the deposit. When funds are received, users will need to confirm the collection of data from the sender before accepting the payment.	N/A	Balance proofs
