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. The first part: build your own blockchain directory from 0 to 1:
1.1 start with imitation, First knowledge of blockchain
1.2 basis of blockchain: analysis of consensus mechanism
1.3 design principle and method of consensus mechanism
1.4 how to quickly clone a blockchain
1.5 how to turn bitcoin into its own private chain - bifurcated bitcoin
1.6 how to turn Ethereum into its own private chain - bifurcated Ethereum
1.7 how to turn ripple into its own private chain - bifurcated Ripple
1.8 how to turn stellar into a private chain of its own, How to develop your own blockchain wallet (windows and MAC) 1.11 how to develop your own blockchain wallet (Android and IOS) 1.12 how to develop an online wallet similar to blockchain.info 1.13 how to increase the security and robustness of your own blockchain network 1.14 how to use coin to handle recharge withdrawal business
1.15 How to use the fund pool to build a mixed currency service
1.16 how to design a new mining algorithm
this process is generally used, but it is also very difficult for ordinary people to complete. The mature projects of blockchain include Ethereum, decent, bitcoin and so on.

3. 1-contains a distributed database
2-The distributed database is the physical carrier of the blockchain, and the blockchain is the logical carrier of the transaction. All core nodes should contain the full of the blockchain data
3-The blockchain serializes the blocks according to time, and the blockchain is the only body of the whole network transaction data
4-The blockchain is only effective for adding, Invalid for other operations
5-public-private key verification based on asymmetric encryption
6-accounting node requires that Byzantine general problem can be solved / avoided
7-consensus progress is evolutionarily stable, that is, it will not collapse in the face of a certain amount of contradictory data of different nodes
8-consensus process can solve the problem of double spending
five characteristics of blockchain:
decentralized
e to the use of Distributed Accounting and storage, there is no centralized hardware or management organization, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system
thanks to the decentralization of blockchain, bitcoin also has the characteristics of decentralization [6]
openness
the system is open, in addition to the private information of all parties to the transaction is encrypted, the data of the blockchain is open to all, and anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
autonomy
blockchain adopts consensus based specifications and Protocols (such as a set of open and transparent algorithms) to enable all nodes in the whole system to exchange data freely and safely in a de trusted environment, so that the trust in "people" is changed into the trust in machines, and any human intervention does not work
information cannot be tampered with
once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high<
anonymity
since the exchange between nodes follows a fixed algorithm, their data interaction does not need trust (the program rules in the blockchain will judge whether the activity is effective by themselves), so the counterparties do not need to let the counterparties generate their own trust by disclosing their identities, which is very helpful for credit accumulation.

4. There are not many domestic enterprises using blockchain technology for software system development. For example, some large enterprises only study blockchain to meet the internal needs of enterprises, and they have not provided software system design and development services. Of course, a small number of domestic enterprises can use blockchain technology for software system design and development. For example, Yingtang Zhongchuang has many development schemes for its trading system. Based on the advantages and in-depth research of blockchain, the application of blockchain will have more projects landing and development.
5. This Canon laser printer icmf426dw features many functions, such as: multiple function, high-speed double-sided printing function, deformation correction function, etc. I know so much, I hope I can help you!
6. The earliest designer of China's virtual currency blockchain is Mr. Zhang Ronghuan. You can go online: Zhang Ronghuan's gene of digital economy indicates that bitcoin blockchain mode is the gene of digital economy in the top-level design of ecological civilization.
7. From the perspective of mechanism design, blockchain can be divided into three levels:
the first level is distributed network, which mainly solves the problem of point-to-point communication network and is also the foundation of blockchain
by establishing a set of cryptography account book system on top of point-to-point communication, we can move from point-to-point communication to point-to-point transaction, which is the second level of blockchain - distributed account book
adding new incentive mechanism and governance mechanism on the basis of distributed ledger is the third level of blockchain - public blockchain, such as bitcoin blockchain.

8. It has nothing to do with designers, but it has a great relationship with everyone. The popularization of blockchain technology will change the existing mode of life, involving all aspects of the field.
