How does Ethereum bifurcate
The capacity of a block in bitcoin is 1m (megabytes). A transaction is between 250 and 500 bytes
according to this algorithm, a block contains about 4194.3 transactions
the confirmation time of a block in bitcoin is 10 minutes, so the seven transactions that a block can process per second may sometimes be less than seven
What are the consequences The bifurcations of
bitcoin are divided into hard bifurcations and soft bifurcations
hard fork means that when the block format or transaction format of bitcoin changes, the UN upgraded nodes refuse to verify the blocks proced by the upgraded nodes
the upgraded nodes can verify the blocks proced by the non upgraded nodes, and they continue the chain they think is correct, so they are divided into two chains
What is soft bifurcationsoft bifurcation means that when the data structure of bitcoin transaction changes,
UN upgraded nodes can verify the blocks proced by upgraded nodes,
and upgraded nodes can also verify the blocks proced by UN upgraded nodes
In the discussion of blockchain, bitcoin and other digital currencies, we often hear the word "bifurcation". So what is bifurcation? What is the effect of bifurcation
blockchain
before talking about bifurcation, popularize a little knowledge of blockchain, so as to help us understand what bifurcation is more easily (if you don't have any concept of blockchain, please read my previous articles, which are all popular words to help you understand what blockchain is)
blockchain, as the name suggests, is a chain composed of blocks. Of course, this kind of chain is just a figurative metaphor. To put it bluntly, data blocks are connected orderly. In bitcoin, the transaction records of bitcoin are stored in the block. The size of the block and the space occupied by the transaction records determine how many transactions can be stored in a block. These transaction records are packaged into blocks, and then the blocks are connected one by one to form a blockchain
We know that bitcoin software, like other software, needs to be updated and modified regularly in order to make it better. So a new version will appear, but not everyone will download the new version, so one miner will run the old version, and some will run the new version. If the old and new versions are not compatible, the blockchain will bifurcate. Because there may be differences between the version blocks and the old version blocks, they cannot be connected to the same blockchain, so there will be two or even more chains, which is called bifurcation
soft forking
soft forking refers to that when the new consensus rules are released, nodes that have not been upgraded will proce illegal blocks because they do not know the new consensus rules, resulting in temporary forking. This kind of bifurcation will be graally repaired with the upgrading of nodes
hard fork
hard fork refers to the permanent divergence of the blockchain. After the release of the new consensus rules, some nodes that have not been upgraded cannot verify the blocks proced by the upgraded nodes, and usually hard fork occurs. Therefore, in the field of digital currency, hard bifurcation often leads to the emergence of new currencies. For example, the hard bifurcation of ethereum led to the emergence of eth
What is bifurcation? What is bitcoin bifurcationEthereum uses fog computing. The data processing and applications of fog computing are concentrated in the devices at the edge of the network, rather than almost all stored in the cloud, which is an extension concept of cloud computing, which is more in line with the spirit of decentralization of blockchain. If all the storage and operations still stay on the centralized server, then it will not be a real blockchain
recently, the hot "ethereal cat" on Ethereum network has led to the congestion of Ethereum network. The problem is that the TPS concurrency per second of Ethereum is too low. The emergence of ethereumfog with fog computing will break the embarrassing situation of Ethereum network congestion, and add powerful decentralized storage and additional computing power to the chain.
after Ethereum bifurcates into etheric fog, the two will exist and develop together< br />
compared with the existing cloud computing, fog computing does not rely on the remote server located in the central computer room, but intelligently connects to the nearest distributed computer resources, so as to achieve the most efficient utilization of computing resources. This topology is characterized by decentralized peer-to-peer network, which is a perfect match with blockchain. If cloud computing represents efficient computing power in the Internet era, then in the era of Internet of things and value networking blockchain, fog computing should be the most efficient way of computing power networking
therefore, compared with the evolution of cloud computing, which is a kind of centralized computing, fog computing is to share computing tasks with all kinds of powerful devices around us, and realize the evolution of decentralized and distributed computing, which coincides with the philosophy of blockchain itself. However, it is necessary to encourage the owners of distributed computing resources to contribute computing power to the fog computing network. It is not only difficult for centralized enterprises (such as Cisco) to organize supply and demand market settlement in real time and monopolize, but also contrary to the decentralized distributed philosophy of fog computing itself, which is difficult to be widely recognized, It is difficult to find a satisfactory solution on how to settle the compensation of fog calculation reasonably
we can see that Amazon's AWS, Microsoft's azure and Alibaba's aliyun are all centralized operators operating centralized computing services, and the combination of blockchain value network and cloud computing network, which are both decentralized philosophy, is almost perfect. Ethereumfog is born for this purpose. Upgrading Ethereum based on Ethereum will really bring fog computing to us. In the near future, many personal computing devices may contribute their computing power to do useful things on ethereumfog chain, and do not waste every resource to earn corresponding returns< We use cloud computing, but it runs in the remote data center; Fog is close to the ground and lingers around us. Fog computing makes both computing and storage decentralized distributed on the devices around us. The combination of blockchain and value Internet makes more people willing to let their computing resources participate in it. The organic combination of supply and demand is becoming more powerful. Ethereumfog etherfog (ETF) is opening the door to the new world of Ethereum.

let's talk about the value foundation of Ethereum - blockchain technology. The original idea of the framework proposed by akamoto is to enable indivials to quickly complete online transactions without traditional middlemen or third parties. This technical framework is known as blockchain. Blockchain is an indestructible digital ledger, which can be set to record not only financial transactions, but also almost all valuable information without fear of tampering
in the simplest model, blockchain is a simple distributed ledger. However, the internal meaning of blockchain is far greater than the surface meaning of its name. Blockchain can transfer the value itself in the process of transaction. As Sally rivers, a technology author of the financial times, said, in terms of bitcoin, blockchain means the same to it as Internet means to e-mail.
