Nationwide recruitment of blockchain agents
Bitcoin is a kind of cryptocurrency based on decentralization, using peer-to-peer network and consensus initiative, open source, and blockchain as the underlying technology
on January 3, 2009, Chuangshi block was born. Anyone can participate in bitcoin activities and issue bitcoin through a computer operation called mining. Since the number of bitcoin protocols is up to 21 million, some people think that inflation can be avoided
in 2010, bitcoin proced a price in the transaction, and the initial price was about US $0.0025 per coin. If compared with the current $30000 each, the "value" of bitcoin has increased by more than 12 million times in about 10 years
many people in the "coin circle" believe that the players behind bitcoin are no longer technicians and blockchain enthusiasts, but global financial institutions
when bitcoin and other blockchain digital assets increasingly get the participation of mainstream investment institutions, it will help to rece the concern about the legitimacy of bitcoin
in November 2020, PayPal, an online payment giant with more than 300 million users, announced to provide bitcoin trading services for qualified US customers after purchasing a large number of bitcoin
in December 2020, Singapore DBS Bank launched bitcoin and other digital asset trading services for institutional investors. In the past three years, the bank has been calling bitcoin a Ponzi scheme...
however, the soaring virtual currency represented by bitcoin has not changed the reality that it is not generally recognized by the mainstream financial market, which means that the higher the value of bitcoin, the higher the value of bitcoin, The more risky investors are
After all, behind the virtual currency, there is nothing but artificial scarcity caused by technologyEth trunk interface is a kind of interface that can be created dynamically. This type of interface can be bound with several physical Ethernet interfaces and used as a logical interface to increase bandwidth and improve reliability
The advantages oftrunk are as follows:
1. Load carrying through trunk interface and traffic load carrying in eth trunk interface
2. When a member's interface is connected to the physical link, the traffic is switched over, and the link is used to improve the reliability of the whole trunk link
3. Total bandwidth of trunk interface
extended data:
trunk specific application
1. Trunk function is used to connect the switch and the server, providing the server with exclusive high bandwidth
2. Trunk function is used for cascading between switches to provide high bandwidth data transmission capacity for data exchange between switches, improve network speed, break through network bottleneck, and then greatly improve network performance (main application)
trunk function example
-- for example, in order to increase the bandwidth and improve the connection reliability, an Internet bar movie server is a al network card, which is bound and connected with 23 and 24 ports of the central switch; If the 1 and 2 ports of the layer 2 switch are connected with the 1 and 2 ports of the central switch, then the central switch needs to make the 1, 2 ports, 23 and 24 ports trunk respectively. Note: the layer 2 switch here also needs to support trunk

The characteristics of blockchain, such as decentralization, peer-to-peer network, time stamp, tamper proof, consensus and smart contract, are all related to digital identity, and they are indispensable. They cooperate with each other and provide a basis for relative trust to some extent
the source of digital identity needs a strong endorsement agency and government support. Just like every citizen's identity card is a truth, we are based on the ID card, and most of the social behavior information is in the hands of the enterprise. Social information in WeChat, payment information in Alipay, shopping information in Taobao and so on, plays an important role in improving user identity information. p>
enterprises are the strongest driving force, and also the channel bridge for users to rely on trust
