Polkadot Founder Lin Jiawen: The most important tool in solving the blockchain privacy problem is zero proof.

From October 27 to 28, Huobi hosted the "Infinite Future - Major Expansion of Blockchain 2020" Business Summit and the 7th Annual Huobi Group Online Summit. Babbitt founder Chang Wei delivered a speech at the conference titled "The Beginning of Hongmeng, The Rise of the Blockchain World, and the Perspective of a Pioneer." In the past, Changzheng focused more on technology development, discussed the development of proposed mechanisms for new technology of channel sharing, sharding, technology encryption, using the data sphere, etc. . Specifically, the recent development of POW approval for DPoS, POA and various BFTs. However, recently there have been fewer updates in the approval process and more recent developments in products like DeFi. This is a natural concept in the construction industry, and new construction at lower levels needs to be turned into new developments in higher level applications.
