Perhaps for some people, we have now entered the second half of Web2.0. With the popularity of the metaverse concept, Web3 has entered people's field of vision more and more frequently. If you want to explain the relationship between them, then maybe Web3 is the Internet foundation of the metaverse.
It’s just that nowadays, the concept of the metaverse is both popular and hasty, so many rules and technologies are still in the exploratory and embryonic stage. For example, if today's network has to complete the transition from information transmission to value transmission, the biggest problem is to use technical means to solve the trust foundation of the Internet.
After all, today’s commercial and economic activities on the Internet still need to be endorsed by a centralized third-party organization, and the problems involved are self-evident, because of the security risks and risks caused by centralized data management. The trust crisis caused by the asymmetry of information and power restricts commercial and economic activities on the Internet today.
Therefore, as early as 1981, some inventors had proposed the idea of using cryptography technology to solve the Internet trust crisis. However, due to the different needs of the times and the complex issues involved behind it, the eCash system, the first anonymous digital payment system, ultimately failed.
Soon after, the idea of "God Agreement" was proposed. In this short paper, author Nick Szabo introduces us to a model that replaces third-party institutions with reliable technical means, that is, "God". He described that "all parties will input value and information into the hands of 'God', and 'God' will return reliable execution results. No one else can peep into information unrelated to the transaction." This is almost a proposal to let the Internet business and achieve a “leap of faith”. Fortunately, God soon showed up!
In 2008, after a large-scale financial tsunami, on October 31, one or a group of masters nicknamed " Satoshi Nakamoto " published what was known as the "Bitcoin White Paper" on the "Cryptopunk" website. "Bitcoin: A Peer-to-Peer Electronic Cash System" stirred up waves with one stone. Bitcoin began to enter people's field of vision and opened a new era.
Because the Bitcoin network can allow hundreds of millions of devices online to exchange information with each other safely and reliably without the need for third-party intermediaries. From then on, the trust system on the Internet is expected to get rid of the constraints of human nature. It can allow us to realize the transfer of value more safely and directly, that is, to send money directly to the other party on the Internet.
Because on the Bitcoin network, the network will automatically confirm and liquidate every ten minutes, and record these data in a linked block in chronological order, and the record of each new block must first be Confirm the data of the previous block. In addition, all confirmation information on this network is open and transparent, traceable across the entire network, and the ins and outs of all information are clear. Therefore, if someone tries to tamper with network information in public in order to steal Bitcoin, this will It is tantamount to stealing under the surveillance of the entire network, which is completely impossible to achieve.
Therefore, the emergence of the Bitcoin network provides a classic application case for the application of blockchain technology , and thus stimulates people's imagination and creativity. As open source code, everyone can download, apply and use it for free. Therefore, Buterin established Ethereum, the king of public chains, on the framework of the Bitcoin network. After more than ten years of development, blockchain technology has also seen more developments and applications in various fields.
It is the emergence of blockchain that has solved the trust crisis for the Internet and given a new digital future to various fields.
