Effect: It is to determine how many latest blocks to be stored in a full node, which will affect the operation cost of each node.
选项：A 维持不变；B 减半；C 加倍
Option: A. Maintain the status quo; B. Halve; C. Double
For blocks after the checkpoint, we will maintain their metadata in memory and will keep their transaction data in disk. If a checkpoint is reverted by attackers, it will cause severe security problem. If we keep less blocks after a checkpoint, the reduced memory/disk cost is small (compared with the cost to maintain the global state), but the system safety will be greatly affected.
