What server does blockchain need

1. A protocol is a set of rules for managing a network. blockchain protocol usually includes rules of consensus, transaction verification and network participation. Agreements often rely on economic incentives - which means they depend on an asset
generally, protocol level assets can also be used as local procts of the protocol (no platform required!) bitcoin is a good example. Bitcoin (capital B) refers to the agreement. The agreement depends on the local asset: bitcoin (small b). This local asset is also used as the end proct: it's the user's means of payment, the store of value, and (to be honest) a degree of hype. Please note that bitcoin does not really provide a platform. It's not very friendly for developers trying to build new procts on it< On the other hand, Ethereum has three levels. It's an agreement that provides the basic rules. This is a platform that enables developers to build new procts on the system. Moreover, because its agreement contains a local asset, it also gets a built-in proct (in the form of ether)
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

2. It can be, but it is usually g by special mining machine, and the mining efficiency of CPU is far less than that of GPU

According to experts, blockchain can be understood as a distributed public ledger, which is connected by various blocks into a chain. In the traditional bookkeeping system, the bookkeeping right is controlled by the central server

on the "account book" of blockchain, every point in the chain can record information on it, forming a point-to-point accounting system. Therefore, blockchain technology is considered as a decentralized technology

For example, in a village of 100 people, Zhang San bought a cow from Li Si and paid him 10000 yuan. In the past, he had to rely on Zhao Liu, a middleman, to transfer his 10000 yuan to Li Si

with the blockchain system, Zhang San can directly record his 10000 yuan to Li Si's account book, and the transaction information will be transmitted to the whole village, that is, the whole blockchain system, so that other 98 people can see the information. The whole transaction process is recorded by the system, which has the advantage of traceability to prevent the loss of Zhao Liu's account book or Li Si's denial of account

extended data

in 2008, Nakamoto first proposed the concept of blockchain. In the following years, blockchain became the core component of electronic currency bitcoin: as a public account book for all transactions. By using peer-to-peer network and distributed timestamp server, the blockchain database can be managed independently

the blockchain invented for bitcoin makes it the first digital currency to solve the problem of repeated consumption. The design of bitcoin has become a source of inspiration for other applications

4. To be exact, blockchain and traditional server cannot be compared together, because blockchain is a technical model, while server is a kind of hardware resource
but if we have to compare them, we can first see the differences or connections between the two characteristics
the traditional server is centralized
take a look at the figure below, it is a typical centralized network, the most central is the server, the others are clients, the server is responsible for providing services to all clients, and the client obtains services from the server, such as downloading files.

6. It is stored on the chain, and the data is stored on the server; It's just that the so-called servers are distributed.

7. Hello, to be exact, blockchain is a technology model, while server is a kind of hardware resource. There will be a combination of the two. For example, the combination of storage type server and blockchain improves information security
with the development of the Internet, data are stored in the storage server, the security of data can not help everyone's worry. Blockchain technology, using cryptography to ensure the security of data transmission and access, in the process of data extraction, can realize the centralized use of unstructured data required by various research, so as to make the storage server data secure
