In the development of the Internet , People can point to landmark events , These events can divide the process into stages . Among these important milestones , Include 1960 The creation of the first wide area computer network in the s ,1970 The development of e-mail system in the s , Ethernet was created in the late 's ,1990 The launch of the world wide web in the's and the creation of the first browser and search engine in the late 's . With these iconic developments , The Internet has changed a lot . To achieve today's Internet format , Every step is crucial .
Again , Looking back on the development of blockchain, we also divide it into several important development stages . Blockchain technology has existed for only a small part of the Internet , So there are likely to be important developments . Experts divide the history of blockchain into at least three important stages .
Stage 1： Bitcoin and digital currency
Nakamoto, who people have never seen in his true identity , Created the bitcoin world , Bitcoin is also an embodiment of blockchain technology . Although blockchain has begun to be used in many other areas , But in a sense , It's specifically designed for this digital currency , It aims to advance the goal of digital currency more widely .
At the earliest stage , Blockchain establishes the basic system of shared public ledger supporting cryptocurrency network . Nakamoto's blockchain ideas make use of the information about bitcoin transactions 1 Megabytes （MB） Information block . Blocks are linked together through a complex password verification process , Formed an immutable chain . Even in the earliest days , Blockchain technology has established many core functions of these systems , It still exists today .
Stage 2： Intelligent contract
Over time , Developers are beginning to believe that blockchain can do more than just record transactions . for example , The founder of Ethereum had this idea , That is, assets and trust agreements can also benefit from blockchain Management . such , Ethereum represents the second generation of blockchain technology .
The main innovation that Ethereum brings is smart contracts . Often contracts in the mainstream business world are managed between two separate entities , Sometimes supervision is assisted by other entities . Smart contract refers to the contract of self-management on the blockchain . They are triggered by events such as the past of expiration dates or the achievement of specific price targets ; As a response , Smart contracts manage themselves , Adjust as needed , Without input from external entities .
But so far , We may still be taking advantage of the untapped potential of smart contracts . therefore , Whether we have really entered the next stage of blockchain development remains controversial .
The third stage ： future
One of the main problems blockchain faces is expansion . Bitcoin is still plagued by transaction processing time and bottlenecks . Many new digital currencies have tried to modify their blockchains to accommodate these problems , It has been successful to varying degrees . future , The most important scalability will pave the way for the development of blockchain Technology .
besides , New applications of blockchain technology have been developed and applied . It's hard to say exactly where these developments will lead technology and the whole cryptocurrency industry . Supporters of blockchain may find this exciting . From their point of view , We live in an era of continuous technological development and development .
At present, the first industry to apply blockchain technology is finance , I believe this will be a revolution in traditional finance . The application of blockchain Technology , Except for the financial industry , There are also many practical application scenarios , And it's all about us . And the future development will make it give more play to its advantages , Let's wait and see .
