## What is the Mechanism of On Chain Reality Check?

An On Chain Reality Check involves validating the actual state of assets, collateral, or conditions directly on the blockchain ledger. This mechanism leverages the immutable and transparent nature of distributed ledgers to confirm facts without relying on off-chain attestations. Smart contracts often perform these checks automatically, querying the blockchain state to ensure all parameters for a financial operation are met. It eliminates trust in external parties for verification.

## What is the Application of On Chain Reality Check?

The application of an on-chain reality check is critical for the integrity of decentralized financial derivatives and options contracts. Before executing a liquidation, for instance, a smart contract can verify the exact collateral ratio on-chain. Similarly, options expiry settlement can confirm the underlying asset's price directly from an on-chain oracle. This ensures that all contractual obligations are met based on verifiable, immutable data. It enhances transparency and reduces disputes.

## What is the Consequence of On Chain Reality Check?

The consequence of robust on-chain reality checks is a significant reduction in counterparty risk and increased trust in decentralized financial systems. By relying on verifiable blockchain data, the need for intermediaries to confirm asset ownership or contract conditions is eliminated. This enhances the security and reliability of complex derivatives products, fostering greater institutional adoption. It also minimizes operational risk associated with off-chain data discrepancies.
