the underlying development of blockchain can't be realized with Java
as the upper development, you just need to dock according to the given open source interface, and then develop what you need with the language you are good at
now there are many blockchain system templates, you can see which development cases

2. It's necessary to supervise. Now the coin chain is in a mess. It's just a lack of supervision. Although Li Xiaolai's story is true, it shows that a few indivials in the currency circle can call the wind and the rain in it, which makes ordinary investors feel embarrassed
technology listing can be realized as long as the regulatory agencies, financial institutions and users are moved to the chain, all transactions are on the chain, and certain management and view permissions are set, which can not only ensure data security, but also use the non tampering and traceable performance of blockchain technology to complete regulatory operations, so that the whole chain circle can develop healthily. It's always manipulated by people, where are the funds coming in? If we don't supervise it well, the market opportunities will be depressed.

3. Because blockchain technology has natural advantages in realizing smart contracts
bitcoin, Ruitai coin, Laite coin, Ethereum and other digital cryptocurrencies all use blockchain technology
blockchain is an important concept of bitcoin, which is essentially a decentralized database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

4. Blockchain is a technology, but it is not a single technology, but the result of the integration of a variety of technologies, including cryptography, mathematics, economics, network science and so on. You can think of it as a distributed shared accounting technology, or as a database, but the database is jointly maintained by all nodes in the chain, and each node has an account book. Because the account books of all nodes are consistent, different nodes can trust each other, and there is no doubt about the data, so we all say that the blockchain has realized trust technically. For detailed professional technology, you can consult some professional technology companies, such as Jinbo technology, which focuses on the development of blockchain related procts, professional R & D team and perfect after-sales service, and you can consult by telephone.

5. Talk about my understanding. Blockchain and the Internet of things are very hot now. There are many articles about trends. Yesterday, I reviewed the articles a few years ago, and some of them grasped the trends very well. To get back to business, I personally think it's a process from point, line, surface to three-dimensional. No matter the blockchain or the Internet of things, they connect things that were not closely related in the past through technological innovation, and become a whole of mutual connection and interaction. Connecting to the whole, you can do whatever you want. I hope it will help you.

The hottest things this year are "bitcoin", "Ethereum" and all kinds of cryptocurrencies, so hot that even aunts and uncles are about to start talking about them. It is no exaggeration to say that 2017 is the first year of the development of cryptocurrency and blockchain technology

as the underlying technology behind bitcoin, the concept of blockchain has only been mentioned in the past two or three years, although as early as 2009, "Nakamoto Tsung" released bitcoin. After this wave of digital currency boom, the concept of blockchain technology has really entered the eyes of all walks of life. I'm afraid it's too early to mention the wide application of blockchain technology, which is still in a very early stage of development. However, e to the arrival of the boom, many technicians and teams have contributed their efforts to build some blockchain concept projects“ Needless to say, as the first application of blockchain technology, bitcoin of "Zhongben cong" has realized the function of distributed ledger, which can realize the first decentralized value transmission of human beings. It can be said that it is "blockchain 1.0". Then Ethereum invented the smart contract, which extended the function of blockchain technology to build applications. It is well deserved to be defined as "blockchain 2.0". However, the blockchain concept projects that came out later did not realize this leap forward role, but only improved to a certain extent at the application level, so they can not be called "blockchain 3.0"

so what is "blockchain 3.0"? Maybe bitcoin OS is the answer: an operation system that is completely based on blockchain technology and follows the concept of blockchain technology. In the 1980s, before Microsoft released the windows operating system, personal computers and Internet technology were still in a non systematic state and could not be popularized. After the release, personal computers were allowed to enter ordinary people's homes, making PC and Internet universal application procts. Recently, bitcoin OS team announced the implementation of the bifurcations of bitcoin and Ethereum on Christmas day, so as to officially publish the plan of developing blockchain OS

anyone who knows a little bit about blockchain technology knows that bitcoin solves the problem of account book, while Ethereum is a smart contract to realize application expansion. Later, a team will launch a distributed storage project. But these systems with only a single functional mole are not "operating systems". The traditional definition of operating system is a huge management and control program, which includes five management functions: process and processor management, job management, storage management, device management and file management. In fact, the OS based on blockchain does not need to change all the five functional blocks into distributed ones, as long as the parts related to the external transmission of value and information can be decentralized and distributed. Therefore, the blockchain operating system should have at least three functions of "account system management, computing resource management and storage resource management", which can realize distributed ledger, edge computing and edge storage. Although it is still too early to define the instry standard in this way, bitcoin OS team is committed to realizing the blockchain OS possessed by these three functional blocks first, and then improving it through iteration

according to the bitcoin OS team, the name "bitcoin OS" is actually "blockchain OS", which is named after "bitcoin", which is also a tribute to the inventor "Satoshi Nakamoto". At present, from the technical details given by the bitcoin OS team, we may be able to see some aspects of this "blockchain 3.0" project

firstly, the management function of the account book system supports locating the ownership of resources according to the account ID, such as the private key; Computing resource management can obtain corresponding computing resources according to the demand, support edge computing, and share distributed computing power. In addition, storage resource management can use storage resources according to the demand, and support edge storage. Compared with bitcoin OS, Ethereum only supports account system and smart contract, which can not meet the distribution of distributed computing tasks. Ethereum only supports the fair execution of contract code, let alone the management of storage resources. So Ethereum is only a custom calculator

in addition, it is worth mentioning that bitcoin OS self customized enhanced smart contract. It supports two modes, which are more flexible and efficient

1. Central computing mode: the outgoing node is responsible for executing the smart contract, and both the incoming parameters and the output results support sipfs to be stored in the storage node

Distributed computing mode: ordinary nodes can claim computing tasks, input parameters and output results support sipfs storage to storage nodes

finally, we also need to mention the built-in sipfs super interstellar file system of bitcoin OS. Sipfs can realize the decentralized storage of technical input parameters and output parameters. At the same time, the file has a life cycle, and the DNA description of the file descriptor is recorded on the blockchain. The file descriptor of sipfs does not exist on the blockchain, but it will be stored in a separate file descriptor data file. After the end of the file life cycle, the blockchain will automatically delete the file descriptor, Realize the intelligent slimming of blockchain

"blockchain 3.0" is worth looking forward to, and bitcoin OS team, as the vanguard, is worth paying attention to and encouraging. We are looking forward to the real blockchain operating system

7. Doctors and nurses are different. Interns have accommodation allocation, but it's not very good. Nurses don't have it. They rent their own houses

8. There are many blockchain projects, and few of them have practical applications. The development of blockchain is still in the early stage of development! If you want to engage, you'd better understand the strength of the project party and the team's belief and attitude towards the blockchain
I learned about a project on the Internet before: akso health chain, which is engaged in blockchain health care project! Committed to solving the problem of health care data island! You can understand and pay attention to it (for reference only, no investment suggestions, thank you)

9. Blockchain technology has the characteristics of decentralization, tamper proof and time stamp proof, which naturally meets the requirements of electronic data storage. The combination of blockchain and electronic data storage can rece the cost of electronic data storage, facilitate the evidence identification of electronic data, and improve the litigation efficiency in the field of judicial storage. Blockchain certificate storage can make data consistent storage, tamper proof and non repudiation proof, and ensure the security of data transmission and access with the help of cryptography. Cipher finance mimacaijing focuses on blockchain information.
