Blockchain completes a transaction
the confirmation times of bitcoin are different from that of Ruitai coin, Laite coin and doggy coin.
blockchain is a distributed system, which is constructed by cryptography. Indeed, blockchain is a technical collection of concepts formed by distributed system and cryptography. We should emphasize that it is not only a concept but also a technical system, At the very beginning, blockchain only represented the account structure of the underlying technology of bitcoin. It was a narrow concept. At the beginning, because the development of this technology should be represented by a special term to distinguish it from bitcoin, this word was used to refer to it, and it became a bigger and richer concept and a complete system
when we think back to cloud computing, cloud computing existed before the word cloud computing was put forward. However, once cloud computing was put forward, it developed rapidly along the concept of cloud computing. I think blockchain also has such characteristics, and it will continue to develop. Once it becomes a complete sub Technology system, all the technologies in the sub fields under blockchain will continue to develop, The algorithms in the sub domain will develop in the direction of qualitative change in the way of adding tests. Blockchain is a kind of distributed line or network trust technology. When I studied blockchain technology, there was no blockchain word. We called it distributed computing. On the technical level, end-to-end. From a macro point of view, the blockchain is composed of multiple nodes participated by Dongfang. It is equal. The cooperation of these nodes needs to complete the mutual verification on the blockchain. At this time, there is no need for a central node to do this
macro: distributed equal deployment system, participating nodes cooperate to complete verification and storage
microcosmic: rigorous data structure is packaged and stored in the block, and logically concatenated to form a chain
digital signature and integrity verification ensure the authenticity, real-time and timing of block data
at last, after learning all the technical features, it has achieved the multi fight, informed group and supervision right, because it is transparent, shared and open. All parties of the alliance should participate in the operation of the blockchain system, which is equivalent to a co construction, sharing, sharing and co governance. When constructing the alliance, I have to think of one thing: what I store to the blockchain, which are transparent and which are encrypted. At this time, I need to determine according to your business system. If someone deliberately cheats, he or she will probably find that your data may be tampered or forged with the participation of the public or even the collective alliance, so he or she will consider the cost of doing evil. In this way, the trust cost of the alliance will be greatly reced, and there will be no friction. Outside the alliance, because you believe that you have adopted the blockchain technology, you will have a higher degree of trust in the services or procts provided by the whole alliance, so this is a very good way of virtuous circle
what should you do to build a blockchain system or to bridge business to a blockchain system? There are two steps, very simple. The first step is to construct several key roles in your business logic. Now consider how many roles there may be. There may be many roles, but now consider them as one. These perspectives must be related in business logic. They need to share and map these rules to the blockchain or put them into scripts at the same time. Next, we will talk about data, which data will be put into the blockchain and which will not be put, because the efficiency of the blockchain is security, which is generally simple and key, and only what needs to be built together is considered. On the other hand, even if some data are put into the blockchain, not all things need to be supervised, but may be closed door, and can only be seen after authorization, One is privacy, the other is regulatory compliance
after the first step, the second step is simpler. You need a convenient and reliable blockchain platform. It is an underlying infrastructure, including books, networks, supply and demand algorithms, and accounts. All these things have to exist. After general checking, you can check and send these four blocks according to your business needs. There is a protocol below. The above layer is mapping. This mapping layer is very important. It abstracts your business into many models and logics, and abstracts them into an easy-to-use system. Then you can develop your business logic on the application system, and then develop the business logic based on the blockchain. This is a fast process. In fact, a good blockchain business platform should have its own application tools, as well as monitoring, viewing and auxiliary tools, just like the early days of the database. At the beginning of the database, if it was just data without auxiliary tools, it would be very difficult to run
next, let's share a small case, which is the case of blockchain business points that we just released. There are a lot of views that we have already discussed. We must use points to make it universal, so that consumers can get profits and businesses can rece the burden. Moreover, we can let points flow and guide real secondary consumption. This is of great significance. We have to consider more when we choose commercial competition. Commercial competition itself has a certain financial or monetary attribute. It is a purely low-risk number, because it has the lowest regulatory risk to the extent of compliance and legality. Second, points can quickly accumulate digital assets, accumulate C-end users, test your blockchain platform to a certain extent, and even test your blockchain technology to verify whether your blockchain platform is right. Finally, derived with financial related attributes, for the expansion of financial means behind all laid a good foundation
according to the path of building a blockchain system that we have just seen, the first step is to make decisions. In the blockchain system, it plays two roles: merchant and consumer. Merchants are also divided into two levels, the points they send, the points they receive, and the points they receive are also divided into two levels, the points they transfer out and the points they receive. Rules are non discrimination rules; Data, integral, some data are very interesting. I can write all the people on it, and I can write the effective information on it. There are some consumer behaviors, such as what to buy, coffee or bread. These data are written on it. I will use a simple example to guide you
the second step is to find a platform for blockchain. In our Bubi blockchain, what do we get? We really got a positive feedback. We think it's a very good feedback. First, digital integral represents a variety of data assets, which can be supported on the blockchain. Second, it may have many users, whether real users or laboratory simulation users. It's no problem to support millions of transactions and storage. Third, it really builds a good foundation for us, which lays a good foundation for the exploration in the financial field.
first, define the
blockchain as an open network ledger. It originated from bitcoin and is the underlying technology of bitcoin. In bitcoin transactions, all the information of transaction records will be packaged into a "block" for storage. With the expansion of information exchange, one block links with another, forming a blockchain
Second, the digital currency represented by bitcoin is a point-to-point e-cash system. Among them, every transaction will broadcast to all participants in the network, and it will be recorded in the account book after repeated confirmation, which is called "blockchain". Each participant will have his own account book. In this way, when false information occurs, it can be broken through mutual verification, so as to ensure network securityin the blockchain, every node is equal, and there is no centralized management organization. This "decentralized" feature makes the blockchain do not need to rely on a third party, its operation does not need any human intervention, and it can independently conct self verification. In addition, the network of blockchain is open to the world, and anyone can query data through the public port, so the whole system is highly transparent
In a word, blockchain is a reliable database and a reliable "account book". In the future, it will be applied in cross-border payment, securities, loans, voting, etc. For example, in cross-border payment, with the security of blockchain, you can remit money to the world anytime and anywhere, which saves a lot of intermediate links and high feesthe centralized trading platform covers the whole trading process including account opening, recharge, automatic transfer and transaction withdrawal. That is to say, when we put our digital assets into the address of the trading platform, the trading platform becomes the trustee of our digital assets, and the control of the actual assets is in the hands of the trading platform
different from the centralized trading platform, the decentralized platform does not need to register an account. It only needs to undertake the responsibilities of asset custody, matching transaction and asset clearing, and does not need to provide non trading function, account system, kcy and legal currency exchange functions like the centralized exchange; On the other hand, in the decentralized trading platform, all operations are realized through smart contracts, and this transaction needs to wait for the confirmation of the blockchain before it is successfully completed
based on the above attributes, the decentralized platform avoids the moral hazard of the trading platform and the centralized attack of hackers to a certain extent. However, in this trading mode, the security of assets depends on the users themselves.
blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.
a small exchange may not need money, and you can even set up your own exchange for $1.2 million
large exchanges, such as fire currency and currency security, should be more than 10 million RMB
for example, some time ago, the voting cost of huocoin was about 30 million yuan
finally, the scope of blockchain is relatively large, not just sending a token to the exchange. Therefore, the exchange on the blockchain is a sick sentence.
1. Regularly clean the st in the computer, turn off the computer, open the chassis, use a hair dryer and blow with cold air< At ordinary times, 360 guard, Jinshan guard and other tools should be used to clean up the system garbage and temporary files generated by the Internet, and check and kill malicious
Italian software
3. The computer configuration is poor, so try to set the virtual memory as large as possible, and install anti-virus software with less resources, such as NOD32, or only one
auxiliary anti-virus software
4. Try to set the IP to static IP, which can rece the startup time of the computer
5. Don't put too many files and icons on the computer desktop, which will slow down the reaction of the computer. Try not to install the software on disk C
6. Regularly defragment the disk. Open the drive of my computer to defragment - properties - tools
select the disk to be defragmented. Open the "disk defragmenter" window - Analysis - defragmentation - the system will start to defragment
.
some miners accept mining, so they can't price by game performance
so the price of rx590 is almost the same as that of rtx2060
