Baidu centralized blockchain platform
according to Xiao Wang, the concept of blockchain as a service (baas) is mainly proposed by Microsoft and IBM. To put it bluntly, it is actually a new type of cloud service, a cloud service combined with blockchain technology. For example, Microsoft's azure cloud computing platform and IBM's bluemix garage cloud platform all provide blockchain as a service baas
blockchain as a service (baas) is a space created by enterprises such as Microsoft and IBM from their own cloud service network to run a blockchain node. Compared with ordinary nodes and exchange nodes, the main purpose of baas nodes is to quickly establish the development environment they need, and provide a series of operation services based on blockchain, such as search query, transaction submission, data analysis, etc. these services can be centralized or decentralized to help developers verify their concepts and models faster. The service of baas node is reflected in: it is more instrumental and easy to create, deploy, run and monitor blockchain.
The decentralization of blockchain refers to the form of social relations and content generation formed in the process of blockchain development. It is a new network content proction process relative to "centralization"
blockchain is an important concept of bitcoin, which is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a batch of bitcoin network transactions, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block
blockchain is unified in the whole network, so it is logically centralized. From the perspective of architecture, blockchain is based on peer-to-peer network, so it is decentralized. From the perspective of governance, blockchain makes it difficult for a few people to control the whole system through consensus algorithm, so it is decentralized

characteristics of blockchain Decentralization:
decentralization, not without the center, but by the node to freely choose the center, freely determine the center. In short, centralization means that the center determines the node. The node must depend on the center, and the node cannot survive without the center
in a decentralized system, anyone is a node, and anyone can be a center. Any center is not permanent, but phased, and no center is mandatory for nodes
with the diversification of network service forms, the decentralized network model becomes more and more clear and possible. After the rise of Web2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can create or contribute content together

Blockchain platforms include Ethereum, Asch and other underlying application development platforms
Ethereum, an open source public blockchain platform with smart contract function, provides decentralized Ethereum virtual machine to process point-to-point contract through its special cryptocurrency ether (ETH)
arch, a decentralized application platform based on side chain technology. Asch is designed to lower the threshold of developers, such as using JavaScript as the application programming language and supporting relational database to store transaction data, which is believed to be very attractive to developers and small and medium-sized enterprises
extended data
in 2008, Nakamoto first proposed the concept of blockchain. In the following years, blockchain has become the core component of electronic currency bitcoin: 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. Bitcoin's design is a source of inspiration for other applications
bitcoin is the absolute mainstream of digital currency, and digital currency is in full bloom. Bitcoin, litecoin, dogecoin, dashcoin are common. In addition to currency application, there are various derivative applications, such as Ethereum, Asch and other underlying application development platforms, as well as NXT, SIA, bitstocks, maidsafe, ripple and other instrial applications
open and transparent
open and transparent. Once all the information recorded on the blockchain is difficult to tamper with and cannot be hidden, users can check it at any time. Generally speaking, as long as the real name authentication is added to the plan, the blockchain will generate nodes, No one can modify (including the platform)
never downtime
the blockchain based on the public chain is not affected by any institution or indivial. As long as the incentive mechanism is effective and the Internet exists, the blockchain will exist. Generally speaking, since the platform service personnel are not available, the platform machine has been working
democratic decision-making
bottom up decision-making, blockchain proposes a variety of different consensus mechanisms to help users effectively form bottom-up decision-making and jointly participate in major decisions. Generally speaking, if the platform wants to modify a thing, for example, the content of the plan can only be carried out after more than half of the people participate in the voting, or the application for mutual aid needs mutual aid fund. When more than half of the people do not agree with the publicity, the platform will not pass. Thank you very much for your patience. If you have any help, please accept it. I wish you a happy life! thank you!
Generally, it's legal, but I don't think it's reliable. If you put it in your wallet, it's equivalent to being there for others, so you can't make your own decisions
at present, the blockchain world all believe in a "God" named "Nakamoto Tsung". They all have a Bible named "bitcoin: a peer-to-peer e-cash system" written by Nakamoto Tsung, even though some blockchain projects in the future have started to be independent (such as eth, gucs, etc.), But it is still unable to change the essential characteristics of constant total circulation and "peer-to-peer payment"
However, the focus of attention is different. For example, Ethereum pays more attention to the development and deployment of smart contracts, while the recent big fire of gucs focuses more on the implementation of Inclusive Finance Gucs hopes that national and cultural differences will no longer be an insurmountable gap. Inclusive Finance will spread to every corner of the world, effectively rece the global gap between the rich and the poor, promote the upgrading of consumer finance, and improve the financial situation of small and micro enterprises and indivials around the world, so that the public can really control their rights and build a fairer and better society
