## What is the Model of Shared Security Models?

Shared security models are architectural designs where multiple independent blockchains or protocols derive their security guarantees from a larger, established network. This approach allows smaller chains to leverage the robust consensus mechanism and validator set of the parent chain without having to bootstrap their own security from scratch. The primary goal is to enhance the security of new protocols while reducing the cost and complexity of maintaining a separate network.

## What is the Architecture of Shared Security Models?

In practice, shared security is implemented through various mechanisms, such as rollups or sidechains that post transaction data back to the main chain. The main chain's validators verify the integrity of the transactions on the smaller chains, ensuring finality and preventing malicious activity. This architecture creates a more interconnected ecosystem where assets can move securely between different layers.

## What is the Consequence of Shared Security Models?

The consequence of shared security models is a trade-off between scalability and security. While these models improve the security of smaller chains, they introduce dependencies on the parent chain's performance and governance. For derivatives platforms built on these architectures, the security model determines the reliability of settlement and the integrity of collateral management, which are critical for maintaining user trust.
