15. What is the incentive for miners in the Drivechain proposal?

• Miners must pay fees to join the drivechain network.
• Mining rewards are reduced to encourage participation.
• Miners receive tokens for each block they mine.
• Combined mining offers an extra profit that miners can earn while performing their usual activities.

16. What is the purpose of the signaling method in BIP 9 (Versionbits)?

• To enable all network nodes to express their support or dissent regarding specific updates or changes.
• To limit user participation in protocol decisions significantly.
• To restrict miners from proposing changes effectively.
• To enforce mandatory updates for all nodes without exceptions.

17. How does BIP 9 (Versionbits) ensure broader participation and consensus among community members?

• By enabling external stakeholders to vote on proposed updates without node participation.
• By limiting participation to developers and major stakeholders only.
• By requiring only miners to signal their approval for any changes.
• By allowing all network nodes to participate in signaling support or dissent for specific updates.
