## On-Chain Data Availability

On-chain data availability is the guarantee that the data required to verify a transaction or state change is published and accessible to all network participants. In decentralized networks, nodes must be able to download and check the history of the ledger to ensure that consensus is being followed correctly.

If data is hidden or unavailable, it becomes impossible for users to verify their balances or the validity of transactions. For derivatives protocols, data availability is crucial for ensuring that liquidation engines can access the necessary price and collateral data to function.

Some scaling solutions move data off-chain to increase throughput, which can introduce risks if that data is not properly secured. Ensuring high availability of data is a major challenge in designing scalable blockchain systems.

It is the foundation of transparency, as it allows anyone to audit the system's state at any time. Without accessible data, the decentralized nature of the protocol is compromised.
