Distributed accounting technology and digital currency
blockchain technology has been questioned by the collapse of the centralized currency exchange, but its potential to solve the trust and centralization problems of the existing information architecture has attracted a lot of attention. Blockchain technology first gained great popularity in the field of bitcoin and digital currency. It uses a single shared ledger to store information. It is no longer to let a single central organization obtain the account book, but to obtain multiple copies of the same distributed account book by different nodes in the peer-to-peer network. Shenzhen yuanzhongrui blockchain technology adopts advanced encryption technology to ensure that any new information in the account book can not be tampered, unless it meets some preset parameters. Moreover, this kind of Ledger has stronger defense against external attacks, such as network attacks, because this decentralized system does not have a single point of failure with high cost of centralized information architecture. At the same time, all trusted nodes can affect any modification of the ledger, provided that they meet the specific preset parameters. These changes will be immediately reflected in the ledger, and all trusted nodes can obtain relevant data to make correct decisions. It can also adjust the design of the distributed ledger, create a hierarchical system within the architecture, and configure appropriate access rights and different levels of authority
blockchain and distributed ledger technology are concive to change the management mode of land registration. At present, the credibility of the real estate market is at the lowest level, which is attributed to the inefficient and opaque property registration system. The system relies on the centralized acquisition of land registration and corresponding property transaction information. Using distributed ledger technology to obtain, manage and modify these information can ensure that the public will not be infringed by land transaction fraud. Similarly, distributed ledger can simplify and integrate cross instry and cross regulatory compliance process, because it contains real-time compliance information needed by government departments, banks, investors and other third parties. By integrating data points of multiple projects and providing feedback on beneficiaries' project participation, we can better track the implementation of social welfare plans
at present, the biggest problems of technology development include: transformation cost of unique data storage system, data reliability verification of network nodes or all levels, privacy and security dimension of decentralized data acquisition, and revision of information technology act. What's important is that blockchain technology will change the way the government interacts with citizens, and this huge change is bound to be resisted by civil servants. These are all possible problems. We should take immediate action to formulate a regulatory framework to guide application development in addition to adopting blockchain technology.
This is a data center switch, which supports virtualization, that is VSU. Configuration reference
core switch 1:
Switch1 # configuration terminal
enter configuration commands, one per line. End with cntl / Z.
Switch1 (config) # switch virtual domain 1
Switch1 (config vs domain) # switch 1
Switch1 (config vs domain) # switch 1 priority 200 -- & gt; The default priority is 100, which is configured as a higher priority. After the VSU is successfully established, it will become the management host
