What Is the Difference between Data Integrity and Data Availability?
Data integrity means the data is accurate, consistent, and trustworthy. Data availability means the data is accessible and delivered to the smart contract when needed.
A system can have high integrity (accurate price) but low availability (oracle is down), or vice versa (oracle is up but provides a stale price). Both are essential for the proper functioning of financial smart contracts like derivatives.

Availability
Latency ⎊ Availability, within cryptocurrency and derivatives, fundamentally concerns the speed at which a system can respond to requests, impacting order execution and arbitrage opportunities.
Data Availability
Requirement ⎊ For decentralized systems, the ability for all participating nodes to access and verify the entirety of the transaction history is fundamental to trustless operation.

Volatility ⎊ Data within cryptocurrency, options trading, and financial derivatives represents the quantified degree of price fluctuation over a defined period, serving as a critical input for option pricing models and risk assessment.
