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. Nodes are the places where the blocks are connected, and the blocks need to be chained to be useful
core analysis:
1. Transparency, 2. Openness, 3. Information can not be tampered with, 4. Decentralization,
5. Detailed analysis
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
1. In a narrow sense, blockchain is a kind of chained data structure composed of data blocks connected in sequence according to the time sequence, and it can not be tampered with and forged by cryptography
2. Broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code.

4. Zhejiang Leiting blockchain Technology Co., Ltd. was established in early 2018, and its team is IPFs professional researchers, dedicated to the promotion of IPFs
and mining machinery research and development, distributed storage application development and mine integration construction. At present, it has participated in the construction of five IPFs mines at home and abroad, and has a number of 100000 megabytes of fixed public IP backbone networks. In the future, it will spread IPFs nodes all over the world. It is the leader in the promotion and mining of IPFs in the world, and the builder of IPFs Explorer alliance< Location of Ningbo mine: it is located in the financial core circle of the eastern new town next to Ningbo municipal government, a sub provincial city with independent urban planning in Zhejiang Province.
the mine is divided into six phases, with a total area of 500 square meters. Each phase is equipped with more than 10bp storage capacity and 2400 IPFs equity nodes. The total capacity is 14400 IPFs equity nodes. Mine technical support: Tongji blockchain laboratory IPFs team point-to-point technology IPFs team
single node hardware configuration: customized enterprise server sharing 16 core 32g DDR3, 24 disk chassis + 1200W power supply, Yingyeda b600 motherboard + Intel CPU (e5-2450l * 2 16 core 32 thread) + al heat sink + 128G memory, Dell / Seagate 6tb SAS hard disk al Gigabit network port adopts 10 Gigabit dedicated optical fiber for Telecom in each phase, and the uplink and downlink are equivalent to 10 Gigabit dedicated optical fiber. The computer room is built according to IDC five-star standard, with electrostatic floor, totem cabinet, heptafluoropropane fire extinguishing system, three-way power supply + UPS power supply + 7 * 24 monitoring system + all-weather administrator on ty
dig before the main network goes online: Based on the digital currency of IPFs storage projects, users have corresponding income at this stage, but the rental fee and operation and maintenance hosting fee are exempted
according to the official launch time of the main network test version (Q4, 2018) and the official launch time of the main network (end of Q1 & Q2, 2019), and according to the comprehensive configuration and the best technical optimization of the thunder mine nodes, IPFs proces about 2-3 filecoins in a single node, and the price of a single filecoin is about RMB 50 in the current futures exchange, with a daily income of RMB 100-200, The annual income of single filecoin is about 50000 yuan. Income in other currencies is not included
according to the application and market heat of IPFs, its reasonable currency price should be RMB 1000-2000, with great potential for later appreciation
in the fourth quarter of 2018, Zhejiang thunder blockchain technology will lay out IPFs mines in other first tier cities in China: Hangzhou, Shanghai, Beijing and Shenzhen, and will lay out overseas mine nodes in 2019.
