What Is the Primary Challenge in Calculating Option Greeks on a Decentralized Platform?

The primary challenge is obtaining accurate, real-time, and unmanipulable inputs for the pricing model, particularly the implied volatility and the risk-free rate. Decentralized platforms rely on Oracles for price feeds, which can be subject to latency or manipulation risk.

Furthermore, the discrete, transaction-based nature of on-chain data makes the continuous, frictionless assumptions of models like Black-Scholes difficult to apply directly, complicating the accurate calculation of Greeks.
