What is the block chain technology? Getting a must-see

"Actual results [...... is ......] the first time, a unique Internet users to transfer digital assets to another Internet user, so as to ensure the safety of the transfer, everyone knows that the transfer has taken place, no one can challenge the transfer of . legality of the consequences of this breakthrough is difficult to overstate. "
- Mark Anderson (Marc Andreessen)

Wikipedia says, from cruising altitude, the appearance of the block chain may not be much different from your familiar things.
Use block chain, many people can make an entry into the record information, and the user community can control how to modify and update the information recorded. Similarly, the Wikipedia entry is not a single publisher's products. Nobody control information.
However, from the bottom view of the unique difference block chain technology becomes more apparent. When both are running on a distributed network (the Internet), Wikipedia is using a client - server network model built on the World Wide Web (WWW) in.
Users have associated with their account privileges (client) can change Wikipedia entries are stored on a centralized server.
Whenever a user access Wikipedia pages, they will receive a "master copy" an updated version of Wikipedia entries. Wikipedia administrators retain control of the database to allow the central authority to maintain access and privileges.

Wikipedia's digital backbone network is similar to the centralized database today's highly protected government, banks or insurance companies reserved. Control of the centralized database normalization owners, including update management, access and prevent network threats.
Distributed database created by the block chain technology have fundamentally different digital trunk. This is also the block chain technology's most unique and important features.
"Master copy" Wikipedia has been edited on the server, all users can see the new version. In the case of the block chain, each node in the network will come to the same conclusion, each node independently update records, becoming the most popular recording official records in fact, not have the master copy.

Broadcasting, and each node are creating your own event later.
It is this difference in the block chain technology so useful - it represents the registration information and innovative distribution aspects, thereby eliminating the need for a trusted party to promote digital relationships.
However, block chain technology, despite its advantages, but it is not a new technology.
Instead, proven technology in new ways. It is a special arrangement of three technologies (the Internet, the private key cryptography and management incentive agreement) the bitcoin creator Satoshi thoughts become so useful.

The result is mutual trust does not require third-party digital interactive systems. Protecting digital work relationship is implicit - from the block chain technology itself is elegant, simple yet powerful network architecture provides.

Trust is a risk judgment between the different parties, in the digital world, determine the trust usually comes down to proof of identity (authentication) and proof of permission (authorization). In short, we want to know, "you say you do?" And "Are you able to do what you want to do?" On the block chain technology, private-key encryption technology provides a powerful tool ownership meet certification requirements. We have the private key is ownership. It also makes a person does not have to share more personal than that required to exchange information, enabling them vulnerable to hacker attacks.

Authentication is not enough. Authorization (have sufficient funds, broadcast the correct transaction type, etc.) require a distributed peer network as a starting point. Distributed centralized network reduces the risk of damage or malfunction. The distributed network must also be committed to record keeping and transaction security network. Authorize the transaction is the result of its application across the network design rules (block chain Protocol).

Authentication and authorization provided in this way allows to interact in the digital world, without having to rely on (expensive) trust. Today, global businesses entrepreneurs have realized the significance of this development - may appear unthinkable, new and powerful digital relationship. Block chain technology is often described as the backbone of the Internet transaction layer, the Internet is the basis of the value of the Internet. In fact, the encryption key and share ledger may encourage users to ensure the safety and formalized the idea of ​​numerical relationships incredible. Everyone from the government to the bank and then to IT companies are seeking to establish this transaction layer.

Digital transactions critical authentication and authorization is done by configuring the block chain technology established.
The idea can be applied to any need for a reliable system of record.
