## Source of Truth

A source of truth is the authoritative reference point for the current state of data in a decentralized system. In the context of smart contracts, the blockchain itself acts as the primary source of truth for all transactions and balances.

However, for off-chain data like asset prices, protocols often rely on oracles as the source of truth. If the source of truth is compromised or manipulated, the entire protocol can be exploited.

This is a common target in flash loan attacks and other derivative exploits. Maintaining a secure and reliable source of truth is essential for the integrity of financial derivatives.

Developers must use decentralized oracle networks to avoid single points of failure. The accuracy of the source of truth determines the correctness of all financial calculations, including liquidations and interest payments.

It is the foundation upon which trust is built in a decentralized environment. Ensuring the veracity of the source of truth is a top priority for security.
