With the development of Internet technology, more and more novel technologies have entered the public's field of vision. If you want to ask which technology is the most popular in today's era, blockchain technology is undoubtedly selected among them.
As one of the most cutting-edge technologies of the Internet, the blockchain gradually penetrates into the daily life of the public, such as "blockchain + agriculture", "blockchain + government", "blockchain + supply chain", "blockchain Blockchain + Education", "Blockchain + Accounting", "Blockchain + Finance", "Blockchain + Smart City", etc., and even "Blockchain + Rule of Law" are gradually being piloted. Gradually it became ubiquitous and gradually infiltrated the ranks of the judiciary.
But even though the blockchain technology is ubiquitous now, there are still a large number of people who know little about the blockchain technology and do not understand why the blockchain technology is welcomed by everyone and can be widely used in various fields.
In fact, if you want to understand the blockchain well, you can start researching from the history of the blockchain. Shilian Finance (shilian.com) understands that blockchain first appeared in 1991, and was mainly used by research institutes to time stamp digital documents. At this time, blockchain technology is like a notary. Prevent document data from being tampered with. However, the technology has played no other role since then, until 2009 when a man named Satoshi Nakamoto used blockchain technology to create the digital cryptocurrency Bitcoin.
It is worth noting that the blockchain is not actually equivalent to Bitcoin. The blockchain is the underlying technology and infrastructure of Bitcoin, and Bitcoin is the application of the blockchain.
In general, the blockchain is essentially a decentralized database. It is a new application mode of computer technology, such as distributed data storage, point-to-point transmission, consensus mechanism and encryption algorithm.
The reason why it is so popular is probably because the blockchain has the following characteristics:
The first is decentralization. The most obvious feature of blockchain is decentralization. It is also because of the decentralization of the blockchain that it can facilitate peer-to-peer transactions. Therefore, no matter whether you are trading or doing anything on this platform, no third-party approval is required. It is understood that blockchain technology does not rely on additional third-party management agencies or hardware facilities. It has no central control. Except for the one-stop blockchain itself, each node completes information through distributed accounting and storage. Self-validation, delivery and management. Some insiders said that decentralization is the most prominent and essential feature of the blockchain.
Secondly, the blockchain is open , which is mainly reflected in the fact that the technical foundation of the blockchain is open source. In addition to the encryption of the private information content of both parties to the transaction, the data information of the blockchain is open to everyone. Anyone can use the public interface to view the data information of the blockchain and develop and design related applications. For this reason, the entire blockchain System information can be considered highly transparent. Although the openness of the blockchain is rarely mentioned, its importance is not bad at all, and it can even be said that openness is one of the guarantees of decentralization.
Furthermore, as mentioned above, the blockchain also has the feature of being immutable . This is because in the blockchain, information is encrypted through cryptography, and once the encryption operation is performed, the data in the blockchain cannot be changed, which improves the credibility of the data to a certain extent.
In addition, blockchain technology also has the feature of security, which makes the blockchain not controlled by any person or entity. Data information is fully replicated (distributed) across multiple computers, and attackers do not have a single point of entry. For the data stored in the network world, as long as 51% of all data information nodes cannot control and modify network data, the blockchain is actually relatively safe and reliable, and it avoids data information corruption caused by subjective human factors. Variety.
It is worth mentioning that the blockchain actually has traceability , which has cross-age historical significance for data traceability. Because of this feature of the blockchain, the blockchain is widely used in aspects such as product traceability in the maternal and infant market, eliminating consumers' concerns about potential safety hazards in the maternal and infant market and improving consumers' purchasing power. In other words, for consumers, using the traceability feature of the blockchain can not only obtain the production information, processing information, logistics information, transaction information and other information of the product, but also effectively protect their rights and health to a certain extent. Safety.
Of course, in addition to the above advantages, the popular point of the blockchain is that it has anonymity . Unless there are legal provisions, the identity information of each blockchain node does not need to be disclosed or verified, and the process of information transmission can be anonymous. The anonymity of the blockchain guarantees the privacy of users to a certain extent. However, the anonymity of the blockchain is also controversial, because although it plays a vital role in protecting people's transactions and privacy, it also provides a "protective umbrella" for certain violations of laws and disciplines.
In general, blockchain technology is so popular not only because it is one of the most cutting-edge technologies today, but also because it has characteristics that are urgently needed for the development of today's society. In this regard, some people in the circle also said that the blockchain technology may subvert the entire Internet world in the near future, and the blockchain has been endowed with greater expectations.
