"End of the article there are benefits."
Block chain has been developed for many years, People's Bank of China recently developed electronic money DCEP (Digital Currency Electronic Payment), the country should also develop the block chain technology. Currency fiery circle moment, then your understanding of the block chain is still in the hair coins, currency speculation stage it? It really behind the times.
This either-block chain block chain
National said block chain is not the currency circle said block chain. People's Daily commentary noted that the block chain "the future has come", but also to remain rational. Block chain technology innovation is not equal to the virtual currency speculation should be prevented from using the block chain that currency speculation air and other acts. Development block chain general direction is not wrong, but to avoid the herd, redundant construction, in order to open space for development block chain in an orderly competition. Perhaps block chain is not just the next generation of Internet technology, is the next generation of cooperation mechanisms and forms of organization.
That, clearly pointed out the need "to coin" and combined with the industry. If you force also in the direction of the currency, it should be carefully considered.
What is the block chain
An explanation of the underlying block chain already rotten Street, not repeat them. Here with a white can understand what is the way it blocks chain: a participant can block chain is accounting, audit, and accounting records almost can not be tampered database. Most Essentially, the block chain is a special database.
About a block just data storage format only, and packaging, mining, power calculation, currency and other terms is simply the process of accounting required formalities, procedures and fees paid for it. Details not to be reopened.
Industry block chain +
What country is the development of said block chain development of it? It is similar to the preceding block chain fiery invoice this category in conjunction with specific business item block chain technology.
As shown above, the block chains can be combined in the financial, judicial, logistics and traceability, supply chain, financial, economic and other aspects of sharing industry, it is also showing a diversified development trend. In particular transaction settlement, deposit certificates and other such natural electronic digital scene.
But the public understand the block chain is another type of application: digital money, wallet and exchanges and so on. These areas have become the Red Sea, but also to optimize policies.
At present domestic Internet companies, such as Tencent, Alibaba, Baidu and Jingdong all in first class to explore the "block chain +" eco-mode with a combination of specific areas.
It also pointed out the good direction to want to block chain of related industries friend, unless that want to play a simple coin "rich", or multi-field combined with the familiar, to build a new ecological model is the future of inevitable direction.
The scarcity of technical personnel
If you are skilled practitioner, then the block chain underlying technology may really be worth your deep plowing of fields. The current block chain and technical personnel in the training stage, China is extremely scarce. At the same time, technology is leading the development of core strength block chain.
We all know that the current block chain there are many issues to be resolved, such as optimization algorithms, storage and efficiency of data transactions. If the technology also has outlet, then block chain direction is clearly predictable.
At the same time, its technical staff also have higher requirements, such as the need for network, consensus algorithm, signature algorithm, security, accounting and other requirements are high. It is so, it is worth your investment of time to learn.
Block chain processes invoices
Having said that you may not understand exactly where the block chain applied. Then give an example: block chain invoices.
Research at the time of this writing the operating mechanism block chain invoices and found that most articles written only in its significance, but made no mention of the underlying implementation, it may be the reason authors do not understand it.
There are also articles analyzing block chain invoice is drawn pseudo-block chain, but electronic invoices only. Here we take a closer look.
The basic flow of electronic invoices include: online payment, invoice apply, billing, reimbursement and tax and other processes. In fact, if not block chain, the process is no different with the operation of electronic invoices. Then, the block chain block chain elements invoice there?
Service flow diagram is block chain invoices. Wherein the chain block related to billing distributed, multi consensus and asymmetric encryption technology. Business is divided into four major step process:
- The tax authorities on tax write invoicing rules in the chain, the chain restrictive conditions on invoicing, approval and control real-time billing.
- Billing invoices to apply for enterprises in the chain, and writes the order information and transaction chain identity.
- Taxpayers claim the invoice in the chain, and update the chain on the taxpayer identity;
- Ticket enterprise acceptance of invoice, invoice status on the chain lock, audit accounted for, the chain of invoice status updates, final payment reimbursement.
We look at this process, in which the invoicing rules clearly written on the block chain, records and billing process of transfer of state is also reflected in the block chain. That data function block chain has been played, it can not be tampered with to ensure that the data on the characteristics of the chain.
The main need is here, where the chain is not public understanding of this public Ethernet and EOS Square chain, but the chain alliance between several organizations, more similar to the super books (Hyperledger). Consensus also made between these organizations reached.
By then the block chain invoice achieve what effect?
- Can not be altered, increase the difficulty of forgery and falsification of invoices;
- Trust transfer, reduce costs reimbursed the company's financial audit, tax investigation;
- Not double flowers, effectively preventing a vote overstatement;
- Encrypted data isolation and privacy protection policy innovation.
Within the institutions involved to solve the problem of information silos, you can understand the whole process of invoice circulation, and all can be traced back. It also solves one vote overstatement, false issues such as virtual arrived.
Finally, look at the overall architecture diagram block chain invoices.
It can be more clearly understood from the figure above database features block chain, it needs a variety of traditional system architectures to support, but at the same time it records the data but also has a natural characteristic of the block chain.
summary
If you just stay on the block chain in those public understanding of the chain of narrow money play, you really might want to refresh a piece of knowledge. Like the above invoice has been applied block chain Tencent independent research and development of the basic platform TrustSQL block chain. This is a typical case be block chain solutions for a specific industry sectors. We hope to bring inspiration to you.
Send Benefits: Focus on micro-channel public number "program New Horizons", reply "003", was "Tencent blocks chain white paper" will refresh your knowledge of the new block chain.
