We have a basic blockchain that accepts transactions and allows us to mine new blocks. But the whole point of blockchains is that they should be decentralized. If they are decentralized, how can we ensure that they […]

Preface In the past decade, POW consensus protocol has been supporting the stable operation of the blockchain system safely, and the problems of energy waste and computing power concentration are also obvious. Therefore, fractal decided to explore in the direction of POS at the beginning of design in 2017, pursuing a more environmentally friendly, safe […]

Order service is a unique concept in fabric. It is mainly used to sort the received data, package the blocks, and distribute them to each node through consensus algorithm. So the consensus algorithm in fabric is embodied in the order node. If you want to learn fabric systematically, you can refer to the video tutorial […]

Preface The concept of distributed consensus In the case that multiple nodes can operate or record independently, the process of making all nodes reach a consensus for a certain state. Through the consensus mechanism, the data of multiple nodes in the distributed system can reach a consensus. Distributed consensus technology is actually the core of […]

Since the country’s opening up to the blockchain policy, the whole blockchain circle seems to have been beaten “chicken blood”, especially the domestic public chain. In a few days, the price has doubled or even higher, as if it has embarked on a broad road. However, the speech from the top of the country is […]

Blockchain must be a well-known new technology now. You must have heard about the bifurcation in the blockchain industry. Bifurcation is the core of blockchain experience, similar to system upgrade. “Branching” a chain is essentially to make changes to the software running the blockchain. According to different situations, there are many problems caused by bifurcation, […]

What is capacity consensus agreement As we all know, consensus mechanism occupies the core position in blockchain technology. In the whole system framework of blockchain, trust is the basis of network operation, while consensus mechanism is the mechanism to maintain trust. It is well known that pow (proof of work) is a node that calculates […]

There is no centralized organization like the bank in the blockchain system, so when transferring information and value, the consensus mechanism solves and ensures the consistency and correctness of each transaction on all accounting nodes. This new consensus mechanism of blockchain makes it operate in large-scale and efficient collaboration without relying on centralized organization. In […]

In the field of blockchain, two mainstream consensus mechanisms, POW and POS, have been debating in the industry. The supporters of both sides have been fighting against each other. Under the competition, two schools have formed, namely, the one based on POW mechanism with calculation power as the basis of bookkeeping right is called calculation […]
