Common Core High School ELA Question of the Day
Test your knowledge with a hand-picked multiple-choice question.
Discussions of blockchain scalability sometimes point to throughput numbers and then pivot to decentralization as a value, while security is listed as another property. Blocks and validators are mentioned, and consensus is said to take time, which is why fees go up when networks are busy. Sharding comes up as well as rollups, which are described as solutions, though the relationship between base layers and these add-ons is not always made explicit. Some projects claim faster finality, but it is not clear how they count or whether the network becomes less open to participants. People bring up sidechains and committees and also say that storage is an issue as history grows. Examples of different protocols are sometimes compared, but the criteria change midstream and it is hard to see why one improvement causes a trade-off elsewhere. The conversation mixes user experience complaints with consensus design ideas, and the analysis skips steps when it moves from a metric to a claim about architecture.
Which revision would best enhance the passage's ability to examine and convey the complex trade-offs in blockchain scalability with college-level analytical clarity?
