   A mining pool operator notices that the network difficulty has increased by 20% over the last adjustment period. The pool's total hashrate has remained constant. What is the expected impact on the pool's revenue?

   • ARevenue will increase because higher difficulty attracts more miners to the pool.
   • BRevenue will remain the same because the pool's hashrate is unchanged.
   • CRevenue will decrease because the pool will find fewer blocks for the same hashrate.
   • DRevenue will increase because higher difficulty leads to higher transaction fees.

   A mining farm has just installed 100 new GPU rigs. The farm manager wants to ensure the GPUs are properly connected to the blockchain network and can participate in a mining pool. What is the essential software component that must be configured on each rig?

   • AMining software that connects to the pool and manages the GPU workload
   • BA wallet software to store mined coins securely
   • CAn operating system with built-in mining capabilities
   • DA full blockchain node to validate all transactions locally

   A miner has just purchased several ASIC miners and wants to connect them to a mining pool. What is the role of mining software in this setup?

   • AIt replaces the ASIC firmware to increase the hashrate of the miners.
   • BIt stores the mined cryptocurrency in a secure wallet.
   • CIt connects the ASIC miners to the pool's server and manages the mining process.
   • DIt calculates the optimal electricity rate for the mining operation.

   A developer is designing a new blockchain for a supply chain application. The network must be resistant to Sybil attacks and provide a clear incentive for participants to validate transactions honestly. The developer chooses Proof of Work. What is the primary reason this mechanism provides Sybil resistance?

   • AIt requires computational work to participate in consensus, making it costly to create many fake identities
   • BIt limits the number of participants to a fixed set of validators
   • CIt requires participants to lock up a financial stake that can be slashed
   • DIt uses a reputation system that rewards long-standing participants
