# Finality Oracles ⎊ Area ⎊ Resource 2

## What is the Oracle of Finality Oracles?

A trusted entity or decentralized network responsible for securely feeding external, real-world data onto a blockchain for smart contract execution. Finality oracles are specialized to attest specifically to the irreversible confirmation status of transactions on a source chain. This external validation is often necessary for cross-chain derivatives to trust the settlement status of the underlying asset transfer.

## What is the Finality of Finality Oracles?

The irreversible confirmation of a transaction or state change on a source blockchain, which is the critical data point required by a destination system. These specialized feeds provide a verifiable, on-chain report confirming that the source chain's consensus has locked in the relevant data. Without this signal, derivatives contracts cannot safely proceed with settlement or collateral release.

## What is the Information of Finality Oracles?

The verified data point regarding transaction finality that is consumed by smart contracts to trigger subsequent actions, such as option expiration or collateral release. Providing this information with high integrity and low latency is the primary function of these specialized data providers. Traders rely on the accuracy of this input for risk modeling in cross-chain derivatives.
