Many people don’t know what a blockchain is. Here’s a detailed introduction. Blockchain is a new technology that subverts the old model. Just like people tend to ignore the invisible but indispensable oxygen, people tend to ignore the crucial thing in the market economy, which is trust. Without trust, no transaction can be established.
In addition, different races, nationalities, cultures and religious beliefs will form a trust gap. Due to the lack of mutual understanding and necessary trust between strangers, transactions are difficult to occur. Market economy appears in large numbers among strangers. The emergence and development of market economy lies in the birth of a new mechanism, which solves the problem of trust between strangers.
The most important mechanism to solve the trust problem is the “trust intermediary” system and model. The third party you and strangers trust is the trust intermediary, the government is the trust intermediary, and the bank is the trust intermediary. In today’s global village era and the Internet era, you sell your goods to strangers who will never meet and who are thousands of miles away. Without the guarantee of trust intermediary, transaction is even more impossible. In the Internet era, blockchain technology has begun to play a role.
If blockchain technology is widely used in the future, you don’t need to go to the bank to prove your income and assets, go to the police station to prove whether you are married, ask the company’s personnel to prove your employment relationship, knock endless red seals and look at all kinds of ugly faces… All these are recorded in the unchanged blockchain. When you need and authorize, it seems that the whole world can be your witness.
The concept of blockchain was first put forward in a paper written by Zhongben Cong, the founder of Bitcoin, in 2008. Blockchain can be understood as a technical solution of public accounting. All data will be open and transparent, and the central server will not be required as a trust intermediary, so as to ensure the authenticity, immutability and credibility of information on the technical level. The immutability of data is very important.
Because blockchain has the technical characteristics of large-scale expansion and data openness and transparency, and because the data of each client is consistent, even if some clients are damaged, the reliability of data security will not be affected, especially to effectively solve the problem of trust between strangers, this technology can be extended to all fields that can be digitized, such as digital currency, payment and clearing, digital bills, proof of interest, credit investigation If blockchain technology is developed, government services, medical records, etc. will be closely related to everyone in the future.
