The chaining chain mainly includes centralization, non tampering, traceability, openness, anonymity and democracy.
The biggest feature of block chain is “decentralization”. Centralization means that data storage, updating, maintenance, operation and so on will be based on distributed account instead of the central server. In this way, we can avoid all kinds of adverse consequences caused by the mistake of “centralization organization” and solve many problems that we encounter in real life, such as centralization of servers, being attacked by hackers, or centralization of agencies.
- No tampering
Another important feature of block chaining is “no tampering”.
The contents of the block chain need to use cryptographic principles to carry out complex operations before they can record the upper chain. Moreover, the contents of the previous block will contain the contents of the previous block on the block chain, which makes information tampering very difficult and the cost of tampering is very high, which is the “non tampering” feature of the block chain.
The characteristics of block chain “non tampering” mean that once data is written to the block chain, no one can alter the data information without authorization. This characteristic is naturally suitable for many areas, such as money supervision in the field of public welfare, efficiency improvement in the field of auditing, copyright protection, medical career and education information authentication in the field of education.
Traceability is also an important feature of block chaining. Block chain is a block chain data structure, which is similar to a chain of chains. The contents of the next loop contain the contents of the previous link, and the information on the chain is interlinked by time sequence. This makes any piece of data on the block chain traceable to its origin through “block chain data structure”, which is the traceability of the block chain.
The application field of this characteristic is also very extensive. Besides the public utilities, auditing field, copyright protection, medical treatment, academic attestation and so on, another important application is supply chain.
Based on the traceability of the block chain, the product is recorded on the block chain at the moment of initial production, followed by transportation, sales and regulatory information. It is recorded on the block chain. Once there are problems, we can trace back to see which links are having problems. As a result, the probability of fake vaccine and toxic milk powder will be greatly reduced.
The block chain is open and anonymous at the same time. Openness and anonymity seem to be contradictory. However, we say that the advantage of block chain is that it can simultaneously satisfy the openness and anonymity of data. The openness and anonymity of the chaining chain also stem from its basic characteristics — de centralization.
Openness Because block chaining is centralization, all network nodes can participate in the maintenance of data records, and the data must be open. Only when it is open can we ensure that all people can participate in the data so as to ensure the safety of the data and make it impossible for others to tamper with the data in broad daylight.
Along with the development of block chaining technology, following the bitcoin system, another Ethernet workshop appeared. This block chain is more advanced than the bitcoin. The Ethernet and bitcoin have different operation systems in advance. The Ethernet is an open source and programmable block chain. Popularly speaking, the Ethernet system is equivalent to building a relatively complete “underlying architecture”. Similar to Android and apple, application developers can develop software on this system. Therefore, the Ethernet system can also be seen as the openness of the block chain, and the “open” version is upgraded.
Therefore, we say that the block chain is a very potential technology, so long as we can fully discover and make use of its openness, it can completely jump out of the bitcoin’s single, digital service limitation, and then apply it to many application scenarios.
The main function of openness is to protect data security and reliability. However, in addition to ensuring the safety of data, we also need to ensure the rights and interests of the nodes on the chain, that is, to protect their trading privacy, and not allow the whole network node to see how much money your home has on this open account. Therefore, the block chain uses some means of cryptography to ensure the safety of private information under the premise of full data disclosure. This is the “anonymity” of the so-called “anonymous” block chain, which is popular in the “dark network”, but the “anonymity” of the block chain is not only applicable to dark networks.
In real life, the “anonymity” of the block chain can play a great role in protecting personal privacy. The most typical thing is the online shopping. Now online shopping is very unsafe. What we buy, our name, address, telephone will be provided to the seller, you give bad reviews, and some sellers send you horrible things to intimidate you. And based on the “anonymity” of the block chain, the seller knows your address but doesn’t know who you are, so that we can protect our privacy.
- Democratic nature
The characteristics of block chain “de centralization” decide that there is no “centralization” authority in the world of block chains, which makes the block chain highly democratic.
The democracy of block chain is embodied in: block chain adopts consensus mechanism, that is, “consensus mechanism”. All nodes in the system can store data and update data freely and safely in the system based on the voting and trust of nodes.
Voting, trust and consultation belong to the category of “democracy”. From this perspective, the “democracy” of the block chain is expected to break the existing production relationship: in the block chain ecosystem, the power to maintain the system is widely distributed to the nodes, and all nodes are equal. Based on the consensus and trust generated by voting, they play their role in the system and make contributions to the system to get rewards.
