Learning block chain Four Notes: block chain versions and architecture
Block chain system maintenance is actually a common data books of the system, all the technical units are designed in order to better safeguard the public data books. Books consistent data node reached by consensus algorithm; ensure tamper-proof as well as send data security through data encryption algorithm books; books extended data through a script expression system category.
Standing nature point of view, we can even believe that the block chain system is actually a specially designed database system or a distributed database system, the database can go in this store digital currency, you can go to store more complex logic smart broader range of contracts and various business data.
Block chain 1.0
1.0 bitcoin block chain is a virtual currency for the Times, representatives of the application of virtual currency, including the payment of its functions, such as virtual currency in circulation. The main currency trading with a digital payment functions to the center of the goal achieve currency to the center of the means of payment.
The most typical representative of bitcoin block chain is 1.0, the development of block chain has been accepted Europe and America market, but also spawned a large number of currency trading platform to achieve some of the functions of money, goods transaction can be achieved. Bitcoin outlined an ambitious blueprint for the future of the currency is no longer dependent on the central banks of the releases, but rather monetary union globalization.
Block chain 1.0 meet the needs of virtual currency, although the block chain 1.0 blueprint is huge, but can not spread to other industries. Block Chaining 1.0 era is the era of virtual currency, the emergence of a large number of coins and other cottage.
Block chain 2.0
Block chain 2.0 refers to the intelligence contract, the contract with the smart money combine to provide a wider range of application scenarios in the financial sector. Block chain with a strong natural advantages for the financial scene. In short, if the cross-border bank transfers it may be necessary to get through a variety of environments, currency exchange, transfer operations, interbank issues and so on. the block chain to achieve the point of operation, to avoid third-party intervention, direct implementation of the transfer point to point. improve work efficiency.
Smart earlier proposed contract is the concept of "intelligent contract is a promise (promises) set of definitions in digital form, including a contract agreement participants can implement these commitments in the above."
Block 2.0 represents the chain is 'Ethernet Square' Square Ethernet is a platform that offers a variety of modules allows users to build applications. Applications on the platform, in fact, is a contract. This is the core technology of Ethernet Square. Square Ethernet provides a powerful programming environment contract, through the development contract, Ethernet Square achieve a variety of commercial and non-commercial complex logic in the environment. Ethernet Square, the heart of the Bitcoin system itself is not essentially different. and Ethernet Square is the full realization of the nature of intelligence contracts. support a contract compiled let block chain technology not only made money, while providing a more commercial, non-commercial application scenarios.
That is to say, Square = Block Chaining + Ethernet intelligent contracts
Block chain 3.0
3.0 means the block chain block chain scenarios in various industries outside the financial sector. Able to meet the more complex business logic block chain is called 3.0 generation of Internet technology after technology innovation, enough to push more industrial reform.
3.0 block chain involved in all aspects of life. Therefore, the block chain 3.0 will be more practical, enabling the industry. No longer dependent on a third party or an agency to obtain trust and build credibility. Can improve the overall system by way of the realization of trust productivity. along with scalability and efficiency, block Chaining range of applications beyond the financial scope will expand to the field of authentication, notaries, audit, domain name, logistics, healthcare, energy, visa, etc., into a future society the bottom of the agreement, will block chain will enter the 3.0 era.
It can be said, is a budding 1.0 blocks chain block chain technology, is 2.0 blocks chain block chain finance technical landing, intelligent contracts direction. The block chain 3.0 is to solve the problem of mutual trust and all walks of life data landing and implement security technology transfer.
