Blockchain technology is a paradigm of distributed systems, and its consistency problem is solved by consensus algorithms. This paper summarizes the existing consensus algorithms and divides them into three types: proof, voting, and Paxos-like. The implementation methods and advantages and disadvantages of some representative algorithms among the three types of consensus algorithms are introduced. Finally, the research hotspots and development directions of consensus algorithms in terms of performance and scalability are pointed out.
In 2020, China has repeatedly expressed its views on "carbon peaking, carbon neutrality" and "building a new power system" on the international stage, and the construction of a new power system is accelerating in China. The important prerequisite for leading the low-carbon development and transformation of the power system is to build a new power system, accelerate the construction of a new power system, by accelerate the conversion of the power structure. It is also an urgent need to accomplish the goal of carbon peaking and carbon neutrality. This paper expounds the background, characteristics, problems and emerging technologies of building a new power system, and provides a reference for the planning and decision-making research of the new power system under the low-carbon environment goal.
