How to solve the pain point of 3D printing industry by blockchai

1. Theoretically, it can subvert the existing social networks, but in fact, it still faces many technical and policy problems. For example, decent, a popular blockchain content publishing platform in recent years, has crowdfunded nearly 5881 bitcoins, about 28 million yuan. This is a decentralized content sharing platform. Anyone can participate in it without any restrictions. However, in the world, it still faces the risk of policy regulation. Now we can only use one sentence to describe blockchain: ideal is full, reality is bony.

2.

Since 2017, the concept of blockchain, which has been popular all over the society and the world, is still heating up, attracting people and social funds; Boost bitcoin, as well as similar network "encrypted digital currency" (such as ether coin, Wright coin, etc.) price rise, created a lot of "overnight rich" myth. The argument that digital currency and blockchain will subvert tradition and profoundly change the world is constantly rising. The start-up and development of blockchain seems to be coming like a roaring sea, but it is more and more concentrated in coin making and speculation, and more and more trapped in the thinking and paradigm of "bitcoin blockchain" of mining and coin making

in the case that bitcoin must be exchanged with fiat money and must join the network trading platform and other auxiliary links in order to play a greater function, the characteristics of bitcoin blockchain such as area center and disintermediation may have serious problems. In the real world, if the transfer of monetary assets is operated through the bitcoin blockchain system, it will actually increase the intermediary link rather than disintermediation. Moreover, because the bitcoin system is highly anonymous and deliberately evades supervision, it is difficult to fully meet the requirements of anti money laundering and anti-terrorism transportation. On the contrary, many new serious problems may arise, Many arguments about bitcoin and blockchain are difficult to hold

those unseen pain points

the so-called labels of bitcoin blockchain, such as "decentralization", "democracy, equality and freedom", can not stand scrutiny; The truth is that if it puts too much emphasis on "decentralization", it will affect efficiency; Bitcoin has not yet become a real currency; The ICO type fund-raising method is not concive to the development of blockchain... But when people enthusiastically pursue blockchain like faith, they can not see these "pain points":

first, bitcoin blockchain is difficult to build a decentralized, democratic and equal society

bitcoin blockchain system envisages the establishment of an equal and democratic world for all participants, but in fact, the core team of coding maintenance and the main forces involved in mining and operation are not so equal and democratic. Due to the influence of computer computing power, the mining and acquisition of bitcoin are not equal as advertised. As a result of competition, the opportunities of mining and acquiring bitcoin are more and more concentrated on a small number of mining pools or nodes with powerful computing power. However, more and more people are involved in mining, consuming resources, but they may not be able to obtain bitcoin. This makes bitcoin more occupied by a few people, and will enhance its voice or influence on the adjustment of network rules

secondly, there are strict conditions for bitcoin blockchain to "de trust" and "de mediate" point-to-point transactions

3. Blockchain has a high degree of technical security and broad technology prospects. It is still in continuous development, improving enterprise efficiency and recing operating costs, and will graally be promoted and applied in other fields and instries
Renren chain is an enterprise level platform service based on mainstream blockchain technology, which can help you quickly build a more secure and stable blockchain environment, rece challenges in blockchain deployment, operation and maintenance, and development, and enable you to focus more on core business innovation, so as to realize fast business on the chain
in the current enterprise management mode, no matter customer relationship management, project management, procurement management, human resource management, there are data security and reliability problems to some extent. For example, sometimes transaction data under the market mechanism is untrue / fake / deleted and changed, and some problems such as making ill considered decisions e to data resource blocking occur, In the long run, it will cause harmful business impact on enterprises. Moreover, some enterprise systems are lack of real-time tracking in the process of the project, which is prone to data disorder and lag, resulting in the inability to timely monitor the project and track the responsibility, low management efficiency and so on, which can be avoided in the early selection of enterprises!

4. With the help of blockchain technology and alliance chain node, wangchain technology integrates and writes the information of commodity raw material circulation process, proction process, commodity circulation process and marketing process into the blockchain, and uses the tamper proof attribute of the blockchain to realize the whole process traceability of one thing one code

5. Now some domestic enterprises have applied blockchain technology to the actual instry. For example, wangchain technology has applied blockchain to financial services, health care, IP right, Internet of things, sharing economy, communication, ecation,
social management, charity, public welfare, culture and entertainment, etc

8. Blockchain technology is the underlying technology of app. Blockchain technology is the best way to establish commercial public trust and mutual trust.

9. In the past two years, blockchain has never been known to the public, and has gained more and more people's attention. It is even becoming a hot emerging field. In fact, it has profound internal logic. However, except for a few companies or research institutions that have invested in it, most people's understanding of blockchain is still in the conceptual stage. They may know some features or technical terms, but they don't really know what it is. As a general technology, blockchain technology can really play the driving force, value and influence of technological innovation only by accelerating its penetration into other fields and integrating with all walks of life. At the present stage, mining high-quality projects has become the only way out of the long night for the whole instry< At present, the digitization level of medical and health field is still in the middle and lower levels, the information circulation is difficult, and hospitals are isolated from each other, which directly affects the efficiency and accuracy of hospital (related service institutions) to query patient data (cases, etc.), and leads to frequent disputes between patients and service institutions. Therefore, digitalization of the whole instry is imperative. At the same time, in the digital part, data security and privacy has become a new problem
these existing pain points can be solved from the root through Mac
the generation mode of blocks and the storage mode of data determine that the data stored on the multi source chain has the characteristics of integrity, non tampering, traceability, privacy protection and time order. These characteristics make the multi source chain have natural advantages in the complex, huge and numerous medical fields
the application of blockchain in the field of healthcare
in the field of healthcare, there are many use cases of blockchain technology, but let's focus on the most promising use cases:

1 health data
as patients move in different medical fields and systems, creating usable and highly complete health records is a big challenge in the field of healthcare. Blockchain may help by creating a reliable data source to track changes between systems and solve many problems related to data integration between private systems. In other words, blockchain can be the glue to integrate highly dispersed medical records
however, this quickly raises the most important non-technical question of blockchain: if a distributed ledger is the source of authority, who "owns" the right to access the part of the blockchain that "you" own? For patients, blockchain makes sense. It will give them more control over their data, because they (theoretically) hold the key to their data
2 medical privacy
in fact, we have all met the problems of personal privacy and data leakage, for example, when we just went to the hospital last week, we would immediately receive a lot of telephone harassment, all kinds of registered, drug sellers and so on
medical data is directly related to our life, health and personal property, so its privacy, security and accuracy are particularly important. But at present, the whole medical system is facing the problem of data sharing across platforms. Blockchain technology can help us better protect, circulate and use these very important data. Duoyuan chain is an active practitioner, trying to boost the transformation and upgrading of traditional medical instry with the potential of technology
specifically, multi source chain uses the characteristics of blockchain technology, such as decentralization, smart contract, tamper proof and information transparency, and combines with n medical resource providers to realize the functions of medical traceability, real-time tracking of data on the chain, resource circulation, etc., which can effectively solve the current situation of medical instry pain points and patients' difficulty in seeing a doctor
3 revenue cycle, reconciliation and fraud
the biggest cost burden lurking in the U.S. healthcare system is continuous tracking services and capital flows: the huge complexity and the distributed nature of our health system mean that it costs billions of dollars a year to try to understand which patients receive which services and which providers provide them. Disputes inevitably arise, and both the insurance instry and health care providers spend a lot of extra time and money to resolve them
e to its independent architecture, blockchain may become the foundation of high integrity tracking function, which can be updated in a near instant manner. This means fewer mistakes (including financial and patient care) and a significant rection in fraud. Given the scale of the field, this may generate enough interest to attract investment to help address these complex technical challenges. To solve the problems of fake drugs, high drug prices, excessive medical treatment, excessive drug use and so on
Application of blockchain in the field of life sciences
the direction of pharmaceutical / Biotechnology R & D is cross organization cooperation, sharing resources among companies, government agencies and research institutions, which is the core of its development. But agencies are often reluctant to share data because they are worried about data theft. Blockchain provides a possibility to hard code trust into the process of collaborative R & D in a magical way. More trust means more cooperation, which in turn increases proctivity
by exploring the impact of blockchain on indivials, the rise of personal genomics means that patients with gene sequences can control their own genome authorization in a way that was previously impossible. Therapeutic research is increasingly focused on genomic information mining. As an important potential technology for obtaining permission to enter indivial anonymous gene sequences, blockchain can give patients more rights, and it may soon become the mainstream technology
in addition, the opportunities of supply chain technology in network security, supply chain management, Internet of things data management and precision medicine of hospitals and pharmaceutical companies are also showing signs of rising
the digitalized medical resources have become "biomedical digital assets", which have strong liquidity, transparency and visibility. Blockchain is not only the infrastructure of the future digital economic society, but also an important magic weapon for the digital transformation of various instries. Embracing blockchain means embracing the future. Speed is the future, and mat multi chain is always on the way.
