Foresure solves this through a multi-layered, game-theoretic architecture known as the **Consensus of Reality**. We do not trust a single source. Instead, the Foresure protocol aggregates data through a decentralized hierarchy. For standardized financial data (such as the price of Bitcoin or the CPI index), we integrate directly with **Decentralized Oracle Networks (DONs)** like Chainlink, which provide institutional-grade price feeds. --- # Agent Instructions This documentation is published with GitBook.
