Overview Privacy-Preserving Computing Infrastructure With the rapid growth of the Internet, the Internet giants represented by FAANG and BAT, by virtue of their technological monopoly status, have collected and stored enormous user data. And with the use of big data and AI, they are enjoying data monopoly and acquiring huge business benefits. Users not only fail to obtain data dividends, but also bear the risk of personal privacy being violated and personal data being abused. The Next Generation Internet is a serverless Internet and a decentralized network. In this Internet,…

Public Blockchain design principles One of the core problems of economics research is the rational allocation of scarce resources. The public blockchain is an open, free, and distributed system that everyone can participate in. A well-designed economic model can ensure the reasonable allocation of public blockchain resources on the premise of maximizing the interests of participants, and at the same time align the interests of each participant with the overall interests of the public blockchain, so that it can pursue its own economic interests while also can contribute to the…

Summary We propose a concurrent Byzantine fault tolerance protocol (CBFT) to solve the efficiency problem of partially synchronous networks. This article analyzes consensus protocols such as PBFT, Tendermint, and Hotstuff. With reference to their best practices, CBFT designed pipeline validation, batch production, and low-complexity view-change to improve consensus efficiency. Distributed network model According to the distributed system theory, the network model of the distributed system is divided into three categories: Synchronous network model: messages sent by nodes will definitely reach the target node within a certain time Asynchronous network model: messages sent…

Governance Overview Blockchain governance mechanism refers to a set of decision rules and action standards for stakeholders in the blockchain ecosystem to agree on decisions. The goal is to allow the decentralized network to iteratively develop over time. In the blockchain, some important technologies, such as consensus mechanism, scalability, security, etc., can be better solved by providing reasonable incentives through the governance mechanism. A complete blockchain governance mechanism should be the combined product of blockchain technology, economics, and politics, including rights distribution, economic incentives, and technological realization. The blockchain’s ecological…
