An insurance company wants to automate claim payouts for flight delays. They plan to use a smart contract that receives flight data from an oracle and automatically pays the insured if the delay exceeds a threshold. Which additional consideration is critical for the smart contract to function correctly?

The smart contract must have a mechanism to manually override payouts.

The smart contract must be written in a low-level language for efficiency.

The oracle must be reliable and tamper-proof to provide accurate flight data.

The smart contract must be deployed on a private blockchain to ensure privacy.

A blockchain network for a government land registry needs to be tamper-evident and have a clear audit trail. They are considering a permissioned network with a small number of validators. Which consensus mechanism would best balance finality and accountability?

Proof of Stake (PoS) with anonymous validators.

Proof of Authority (PoA) where validators are known government entities.

Delegated Proof of Stake (DPoS) with elected delegates.

Proof of Work (PoW) with a large number of miners.
