Suneng consensus SWF blockchain

1. 1. What is the technology of blockchain?

2. There are many consensus mechanisms in the blockchain. The advantage of the pow consensus mechanism behind bitcoin, the most influential one, is that it is secure and can not be tampered with. The disadvantage is that it is too slow to process only seven transactions a second

3. At present, there are four main types of consensus mechanisms: pow, POS, dpos, pool
1. POW workload proof, which is familiar with mining, calculates a random number that meets the rules through and or operation, that is, obtains the bookkeeping right, sends out the data that needs to be recorded in this round, and stores it together with other nodes in the whole network after verification
advantages: complete decentralization, free access of nodes
disadvantages: bitcoin has attracted most of the computing power in the world, and other blockchain applications using POW consensus mechanism are difficult to obtain the same computing power to ensure their own security; Mining causes a lot of waste of resources; The period of reaching consensus is long, which is not suitable for commercial application.

2. Proof of rights and interests of POS, a mechanism of upgrading consensus of pow; According to the token proportion and time of each node; It can rece the difficulty of mining in equal proportion, so as to speed up the speed of finding random numbers< Advantages: to a certain extent, it shortens the time to reach a consensus
disadvantages: mining is still needed, which does not solve the pain point of commercial application in essence

3. Dpos share authorization certification mechanism is similar to the voting of the board of directors, in which the coin holders cast a certain number of nodes to verify and account on their behalf
advantages: greatly rece the number of participating verification and accounting nodes, which can achieve second level consensus verification
disadvantages: the whole consensus mechanism still depends on token, and many commercial applications do not need token to exist

4. Pool verification pool, which is based on traditional distributed consistency technology and data verification mechanism; It is a consensus mechanism widely used in the instry chain at present.
advantages: it can work without token, and realizes second level consensus verification on the basis of mature distributed consistency algorithms (pasox and raft)
disadvantages: the degree of decentralization is not as good as that of bictin; The multi center business model is more suitable for multi-party participation

it has great advantages in using consensus mechanism to ensure data consistency (the consensus mechanism is first proposed by ripple, and the network transaction synchronization mechanism with data correctness priority. In the consensus network, no matter how the software code changes, if you can't reach a consensus, you can't enter the network, let alone fork)
- - - - - - - -
PS: a little black, although the consensus mechanism can absolutely ensure that there will be no hard bifurcation at any time. However, the disadvantage of this mechanism is obvious, that is, it is much longer than the current bitcoin network to reach a consensus with other nodes. In extreme cases, the consequences of disconnection in ripple consensus mechanism network are also very terrible

it is possible that one day after the power failure in your home, the whole system will no longer be able to reach a consensus with other rippled nodes (in fact, the consensus mechanism requires more than 80% of the nodes to acknowledge your data before your submission will be accepted by other nodes, otherwise it will be rejected by exclusive nodes), Even you can only empty all your 500 GB data and resynchronize to connect to other ripple nodes

so at present, the existing rippled end is not suitable for civil use (if it is commercial, the impact is relatively small. For example, RL's own rippled node is hosted in Amazon cloud data center. If it has no response for a long time, it can make high claims, and there is almost no break in that place except for large disasters). This is one of the aspects RL has always wanted to improve.

4. Before October 2018, it seems that the fastest one is REBO, next to EOS. After October, these public chains are basically silent in terms of speed, because bitconch of Baker chain has achieved 120000 TPS Based on many technical advantages, which makes it possible for applications to land. Therefore, the world's fastest public chain is the world's fastest public chain, which can be said to be the leader.

5. Non ferrous stocks in the performance of small cap stocks: mainly Baotou Steel Rare Earth, Yunnan copper, Shandong gold, Zhongjin gold, Tongling Nonferrous and so on

small cap stocks refer to the relative and large cap stocks. Large cap stocks: usually refer to the stocks of listed companies with a large number of outstanding shares. On the contrary, small cap stocks are the stocks of listed companies with a small amount of circulating stocks. At present, in China, the circulating stocks of no more than 100 million stocks can be regarded as small cap stocks<

nonferrous metals is the abbreviation of nonferrous metals, nonferrous resources is related to nonferrous metals mining, smelting and other instries of listed companies
typical Baotou Steel Rare Earth, Zhongjin gold, Tongling Nonferrous Metals, Yunnan Copper and many other, specific can enter the market software plate, check the "nonferrous metals" plate, in which more than 60 stocks are very detailed. There is also the concept of mineral resources, which reflects the main business transformation of some listed companies involving mineral resources.

6. Generally speaking, the competition of blockchain public chain is fierce now, because the public chain project is the foundation of blockchain ecology, and the public chain is a super project with huge system, extremely complex and extremely difficult. At present, the overall market situation is similar to that in the early days of the computer system, which started with the development of technology; Linux operating system and UNIX (Younis) are changing, but in the end, windows dominates and apple OS coexists for a long time< br /> 
at present, Ethereum and EOS are the most popular public chains. However, the market value of EOS has plummeted after its epic loophole recently, which has been downplayed by many media. Often the most promising at the beginning may not win in the end. Recently, because of their innovative consensus algorithm, they proposed quite innovative CPOs and focused on a new public chain project

their name is gaiaworld public chain, and their CPOs consensus algorithm is their core technology. Specific technical details can go to the official website to see the white paper, in short, TPS speed has reached a new height, faster than Ethereum, and can support the layout of large projects< br /> 
at the same time, they have innovated two other technologies. Parallel chain technology can make it easier for other developers to release side chains, and then aegis protocol, which is a specific smart contract protocol&# 160;< br /> 
now there are so many air projects, it's really hard to distinguish the good from the bad, but I think the technology platform is the future
hope to adopt

The video card is not broken, but can not open the machine fault analysis and troubleshooting are as follows:

1. The cause of computer st: the computer st is too much, resulting in abnormal computer heat dissipation, resulting in normal boot. The host machine is disassembled to clean the st, and the blower or blower is used to blow the st. After the video card and memory mole are disassembled, the gold finger is wiped with an eraser, and then the machine is installed again and restarted

2. Monitor or connecting line fault: the best way is to use another connecting line to connect another monitor which can be used normally

3. Graphics card or graphics card contact failure: after removing the connecting line, connect it to the on-board graphics card of the computer. If the display is on, it may be the graphics card or graphics card contact failure. It is recommended to remove the graphics card, wipe the gold finger of the graphics card with an eraser, and then plug it in again

4. Problems with memory mole: if the memory mole is not inserted stably or fails, remove the memory mole, wipe the golden finger of the memory mole with an eraser, and then insert it again

remarks: if conditions permit, you can use the diagnostic card to directly plug it into the main board of the computer. The fault code displayed by the diagnostic card can specifically guide which computer and where the hardware has a problem, and can quickly solve the problem. If not, the corresponding faults can only be eliminated one by one
