12.3 Oracle and Validation Layer

The integration of real-world data into FreCx is facilitated through an oracle layer. The oracle acts as an intermediary that:

• receives data from external systems

• validates the authenticity and format of the data

• ensures consistency across multiple inputs

• submits verified data to the blockchain

This process is critical because blockchain systems cannot inherently verify external data. The oracle layer introduces a controlled mechanism for bridging this gap while maintaining trust.

Validation may include:

• timestamp verification

• source authentication

• data consistency checks

• aggregation across multiple inputs

Only after these checks are completed is the data considered eligible for on-chain submission.
