Blockchain Chinese network

1. In many cases of blockchain commercial application, we can always see the word baas. Baas is the abbreviation of blockchain as a service, which is translated into "blockchain as a service" in Chinese. So what is blockchain as a service baas? With this question, we will follow Xiao Wang of Renren blockchain technology team to discuss it carefully
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.

2. Blockchain platform, do you want to see blockchain information? Here is Amway password finance, general chain circle, coin circle, DAPP and other information.

3. At the beginning of the blockchain, I was confused and went to all kinds of communities and wechat groups to read all kinds of CSDN, but I think the more professional ones are Babbitt, Ethereum Chinese network, understanding basic knowledge, and a forum called lookbc, which specializes in blockchain. It's quite good. There are a lot of sections, and there are all kinds of white papers. The information is very full and the activity is high, I see it from there now

5. Bitcointalk Chinese area and reddit bitcoin area are two popular blockchain forums abroad
Babbitt and bitcoin house in China are well-known information websites
European crowdfunding is an attempt of "blockchain + crowdfunding" project in China
NASDAQ is a leader in blockchain applications.

6. Coin security is the No.1 exchange in cryptocurrency, which means that coin security has a more complete ecology than Ethereum. In the future, the public chain can feed back the business of coin security master station, so from the perspective of ecology, coin security has a larger pattern.

7. In the traditional case, no matter the size of the system behind a database, the database is like a large ledger. For example, the database of a certain treasure is like a big account book, which records how much money a user has and how much money b user has. If a user pays one yuan to B user, a treasure will add one yuan to B user's account and subtract one yuan from a user's account. Therefore, the change of database can also be regarded as an accounting behavior

we usually think that the one who maintains the system is the one who manages the database, and other users have no right to participate. Just like the users of a certain treasure can not participate in the specific bookkeeping behavior

but blockchain subverts the tradition and lets every user in the system participate in it

blockchain is like a large total account book. Every user in the system can participate in competitive bookkeeping. In a certain period of time, the system will find the fastest and best users among competitors. The user writes the data changes in this period to a block, just like writing to an account page, and copies this account page to all other users in the system for backup, completing the whole action. In the next period of time, every node in the system has a of the complete ledger

since each block data is linked together through cryptography technology, we call it "blockchain" or "distributed ledger technology"

blockchain, let the whole people participate in bookkeeping. Because there is no specific bookkeeper in the system, any part of the nodes in the system will not affect the operation of the system if they are lost or destroyed. It is safer for all people to keep accounts. The system stipulates that the same number of accounts with the largest number are true accounts, and a small number of accounts that are inconsistent with other users are false accounts. This makes it difficult for a blockchain with enough nodes to be attacked and tampered with. These nodes are distributed in any corner of the Internet. Unless you are God and can control most computers in the world, you cannot tamper with them. Therefore, blockchain is considered to be the most secure way of data management in history. National bookkeeping is more efficient. Because there is no centralized intermediary organization, it can run automatically through pre-set proceres, which can greatly rece costs and improve efficiency, and ensure that the process and content of account records are open and transparent

bitcoin is only an experimental application of blockchain technology in the field of payment. Blockchain can also be used in a broader field, including medical treatment, supply chain, Internet of things, security authentication, social networking and artificial intelligence The economist called blockchain "the trust machine" and believed that it would have a huge and far-reaching impact on global finance and even social structure

to sum up in one sentence, blockchain technology is a way that enables all participants in the system to work together to record and maintain a reliable data log under the environment of multi-party without mutual trust through cryptography technology

bitcoin, blockchain content publishing platform decent and lightcoin all use blockchain technology, and anyone can participate in it in theory.
