## Explain the Concept of “Data Immutability” on a Blockchain.

Data immutability means that once a piece of data (like a transaction or an oracle price update) has been recorded on the blockchain and confirmed, it cannot be altered or deleted. This is enforced by cryptographic hashing and the distributed nature of the ledger.

This characteristic is crucial for financial derivatives, as it ensures that the historical record of prices and trades is trustworthy and unchangeable.

## Glossar

### [Immutability](https://learn.greeks.live/area/immutability/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Provenance ⎊ Immutability within cryptocurrency, options, and derivatives signifies the unalterable record of transaction history and contract terms, crucial for establishing trust and mitigating counterparty risk.

### [Cryptographic Hashing](https://learn.greeks.live/area/cryptographic-hashing/?utm_source=crypto.greeks.live&utm_medium=referral&utm_campaign=satellite)

Function ⎊ Cryptographic hashing functions serve as a fundamental building block in blockchain technology, transforming an arbitrary input data set into a fixed-size, unique output string, known as a hash digest.

        "caption": "Two mirrored, elongated forms, one aquamarine and the other pale tan, create an X-shape against a pure black void, converging at a dark, geometrically detailed central node that suggests rotational or pivotal action. This high-contrast, minimalist presentation conceptually maps to the inherent dualism in constructing cross-asset exchange traded products or executing complex option delta-hedging maneuvers within DeFi protocols. The composition powerfully visualizes the concept of symmetric payoff structures often observed in butterfly spread implementations or the paired liquidation dynamics inherent in undercollateralized stablecoin arbitrage strategies. Specifically, the visual opposition speaks to the balancing act required when managing basis risk between spot market liquidity pools and off-exchange dark pool order flows for volatile tokens. The central element implies the execution engine or the settlement layer where derivative contracts like options or futures converge for final margin settlement or contract termination, reflecting crucial concepts in transparent blockchain-based financial engineering and efficient capital deployment across layered decentralized exchanges."
