  Blockchain technology has seen tremendous development over the past few
years. Despite the emergence of numerous blockchain systems, they all suffer
from various limitations, which can all be attributed to the fundamental issue
posed by the DCS trilemma. In light of this, this work introduces a novel
private blockchain system named DCS Chain. The core idea is to quantify the DCS
metrics and dynamically adjust the blockchain's performance across these three
dimensions, to achieve theoretically optimal system performance. Overall, our
system provides a comprehensive suite of blockchain essentials, including DCS
quantification, consensus protocol adjustment, and communication network
simulation.
