Distributed accounting technology and digital currency

1. That's a good question. Let me give you an example. For example, when I deposit 100 yuan in the bank, the data of this deposit is only recorded in the bank's database, which can't be obtained by others, namely "central bookkeeping". The blockchain is a distributed accounting, a new information recording technology, and it is "encrypted" and "distributed". The data does not exist in a center, but is stored once on the computer of the whole network. For example, if I transfer 100 yuan to you, I will shout to all the computers in the whole network. Let's record the accounts together, that is, "Distributed Accounting".
2. Blockchain technology is also known as distributed ledger. Generally speaking, if we assume that the database is an ledger, reading and writing the database can be regarded as a kind of bookkeeping behavior. The principle of blockchain technology is to find the fastest and best person for bookkeeping in a period of time, and then send this page of information of the ledger to everyone else in the whole system. This is equivalent to changing all the records in the database and sending them to every other node in the whole network, which can not only ensure the data security, but also ensure the authenticity of the data, so as to enhance the social credit.
3. Bookkeeping means mechanisms such as distributed bookkeeping, collective agreement and intelligent consensus. Blockchain technology presents information processing characteristics such as centralization, open sharing, authenticity and reliability, which has aroused increasing attention and application in the financial field, especially in the field of Internet finance. There are many blockchain system development companies. Blockchain technology development enterprises like Renren chain are reliable. You can learn more about them
4. For the benefits, jinwowo feels that the biggest benefit is to obtain great security. First of all, there is a central ledger, so it cannot be destroyed. As like as two peas, each node is only part of the system, and each node has the same rights. Destroying some nodes has no effect on the system at all. Secondly, you can't cheat, because unless you can control most people's computers in the system to make changes, the system will refer to the opinions of most people to decide what is the real result. As a result, it will find that it is totally meaningless to modify your own account book (because others don't admit it). Secondly, since there is no centralized intermediary, making everything run automatically through preset proceres can not only greatly rece costs, but also improve efficiency. Since everyone has the same account book, it can ensure that the process of account book recording is open and transparent.
5. Blockchain and distributed ledger technology make digital currency development more reliable
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

Switch1(config-vs-domain)# exit

Switch1(config)# vsl-aggregateport 1 ------> At least two VSL links are needed, and the reliability of one link is low. When link oscillation occurs, VSU will be very unstable

Switch1(config-vsl-ap-1)# port-member interface TenGigabitEthernet 1/1 ------> Configure VSL link, heartbeat link and traffic channel between VSU active and standby cores

Switch1 (config-vsl-ap-1) ﹥ port member interface tengigabit Ethernet 1 / 2
Switch1 (config-vsl-ap-1) ﹥ exit

core switch 2:

switch2 ﹥ configuration terminal
enter configuration commands, one per line. End with CNTL/Z.

Switch2(config)# switch virtual domain 1 ------> Domain ID must be consistent with the first one

switch2 (config vs domain) # switch 2 ----- & gt; The second device must change its ID to 2

switch2 (config vs domain) { switch 2 priority 150

switch2 (config vs domain) { exit
switch2 (config) { VSL aggregateport 1 ----- & gt; At least two VSL links are needed, and the reliability of one link is low. When link oscillation occurs, VSU will be very unstable

Switch2(config-vsl-ap-1)# port-member interface TenGigabitEtherne 1/1 ------> Configure VSL link, heartbeat link and traffic channel between VSU active and standby cores

switch2 (config-vsl-ap-1) # port member interface tengigabit Ethernet 1 / 2
switch2 (config-vsl-ap-1) # exit

7. Yes?
8. It depends on your choice. The legal currency area or the currency area is OK.
