abstract: This paper will introduce seven common consensus algorithms in blockchain, hoping to help readers explore blockchain. Blockchain technology originated from bitcoin and was originally an underlying technology of bitcoin and other digital currencies. Blockchain integrates cryptography, networking technology, consensus algorithm, smart contract and other technologies. With the gradual maturity of blockchain technology, it has […]

The transaction processing mode of blockchain technology is very different from the traditional mode. It designs a rigorous and orderly data structure at the technical level, introduces a strong mechanism of co construction, sharing and co supervision, and constructs a set of distributed shared general ledger to increase network trust. In general, blockchain technology is […]

Blockchain is the underlying development technology of bitcoin, which is well known. However, as the underlying development technology, blockchain needs hierarchical structure to process data and run. Data layer The data layer is the bottom layer of the six hierarchies of the blockchain. We can understand it as a database, but for the blockchain, it […]

Since October 24, the national high-level voice on the blockchain technology, the traditional industry giants and national giants began to sweep the whole industry. In fact, giants like Alibaba, Huawei, Tencent and Baidu are already ready to go. However, for these giant alliance chains, both the underlying facilities and ecological construction have been very perfect, […]

Whenever you see the blockchain project mentioned in the white paper, your first reaction is to express doubt. It’s not that it’s impossible at all, but that it’s necessary to take high TPS as a selling point, and to put it so high, it’s just that there is no it common sense. How bold do […]

In this article, the author will start with the creation of the vapor node, and then expand and explain the source code involved in the process of the vapor node block. As the first article in the series of source code analysis of vapor, this paper first introduces vapor. Vapor is the high-performance side chain […]

Tendermint Due to work reasons, I started to contact hyperledger fabric two years ago, and its community is still very active. It has developed from v0.7 to v2.0 now. But we have to say that the volume of fabric is still very large, which is difficult for secondary development. So recently, we started to turn […]

With the advent of BTC system, blockchain technology has been recognized by more and more people in the past 10 years. Blockchain has built the value network foundation in the era of digital economy. In the economic model, consensus mechanism, cryptography and other technical problems behind the blockchain public chain, there has always been a […]

What is “on chain”? What data and logic should be “linked”? Can files be linked? Can you batch check data on the chain? What is “under the chain”? There are many problems in “on chain” and “off chain” in one article. What are “on chain” and “off chain” The chain of block “chain”, including“Data link”And“Node […]

As a tool for system decentralization, blockchain does not necessarily pursue “absolute” decentralization of the system, but the degree of decentralization relative to centralization. In the content of the previous issue, we mentioned the scalability of the topic “ternary paradox” of blockchain public chain. In this issue, we will continue to discuss the “core” of […]

At present, there is a consensus mechanism in the global public chain infrastructure, which stipulates how to compete for accounting among nodes. At present, the most mainstream consensus mechanisms are ow, POS, dpos, pbft and dbft, with different emphasis on speed, security and centralization. However, some public chains choose to use the hybrid consensus mechanism. […]

Author: qinyutong, chengyueqiang Consensus mechanism is a distributed consensus algorithm for blockchain transactions. With the continuous promotion of blockchain technology, consensus mechanism, as the core of blockchain, has attracted more and more attention. Consensus mechanism plays an important role in protecting data consistency. In this paper, eight common consensus mechanisms are selected. According to the […]
