What is blockchain? In essence, blockchain is a method of distributed data storage, which brings immutable benefits. Blockchain is a decentralized system, and in order to ensure that the behavior and state of all participating nodes are consistent in a decentralized environment, “consensus” needs to be introduced.
It can be said that without consensus algorithm, blockchain cannot guarantee the unification and authenticity of data in each block. For beginners who want to learn blockchain development, consensus algorithm is a basic skill that must be mastered.
In the traditional distributed database, there are also some consensus algorithms, such as raft, PaxOS. How is this different from the consensus algorithm of blockchain technology? What are the categories of blockchain consensus algorithms? We will solve these problems in this technical workshop.

Topic: Consensus algorithms in blockchain
Introduction: Blockchain is a decentralized system. In order to ensure the consistent behavior and state of all participating nodes in a decentralized environment, “consensus” needs to be introduced. Some consensus algorithms that you may be familiar with are as follows: Raft, PaxOS, these are common consensus algorithms used in centralized distributed systems. There are some differences between these algorithms and the consensus algorithms in blockchain. Please bring your laptop and watch the views and practical experience of Wu Shouhe, core architect of ion chain.
