A company is choosing between a federated bridge and a trustless bridge for a high-value asset transfer. They have a limited budget but also need to maintain a high level of security. Which factor should most heavily influence their decision?

The trust model and the value of the assets being transferred

The development cost of the trustless bridge

The number of validators in the federated bridge

The regulatory requirements for the asset transfer

A bridge has been exploited, and the team suspects that a group of validators colluded to sign a fraudulent transfer. The bridge uses a 5-of-7 multisig. What is the most effective way to prevent this from happening again?

Increase the multisig threshold to 7-of-7

Require validators to use hardware security modules (HSMs)

Use a trusted third-party auditor to review all transfers

Implement a slashing mechanism that penalizes validators for fraudulent behavior

A Web3 platform wants to enable users to take out loans collateralized by assets on another blockchain. They plan to use a bridge to transfer collateral and an oracle for price feeds. What is the most significant risk they should mitigate?

Users may not understand the cross-chain process

The oracle may provide stale price data, leading to under-collateralized loans

The platform may not be compatible with all browsers

The bridge may be exploited, causing the collateral to be stolen

What is the primary purpose of the Cosmos network in the context of blockchain interoperability?

To create an ecosystem of interconnected blockchains that can communicate through the IBC protocol

To offer a cloud storage service for blockchain data

To provide a single blockchain that hosts all decentralized applications

To replace the need for smart contracts in decentralized applications
