The night of blockchain waves

1. Now there are thousands of blockchain games, and the top five in spiderstore are: encryption hero, cloud dragon, ethereal elf, blockchain cute, ctypto default
2. Blockchain has developed in five stages
1. Germination stage: the real germination stage of blockchain was from 2007 to 2009. In 2008, a Japanese American with the pseudonym of Nakamoto first expounded a new fantasy report on electronic money in the form of a synonym on the cryptography discussion group, and bitcoin came out. As early as 2007, Nakamoto began to explore a series of new technologies to create a new currency. On October 31, 2008, bitcoin white paper was released, and on January 3, 2009, bitcoin system officially began to operate
the main technologies supporting bitcoin system include hash function, distributed ledger, blockchain and asymmetric encryption; It can be seen that these technologies build the initial version of the blockchain, and it can also be said that the blockchain is the underlying technology of bitcoin. During the three years from 2007 to 2009, bitcoin was an experimental stage in which a very small number of people participated, and the real commercial activities had not really started
2. "Geek" niche stage: here, "geek" refers to people who are crazy about Internet technology and take technological innovation as fashion and life. On February 6, 2010, the first exchange of bitcoin appeared. On May 22 of the same year, someone bought two hamburgers with 10000 bitcoins. On July 17 of the same year, the exchange Mt. GOx was established, marking the official inflow of bitcoin into the market. Nevertheless, the only people who can really understand and enter the market to participate in bitcoin trading are geeks who are keen on Internet technology. They discuss bitcoin technology on the forum, mine for bitcoin on their own computers, and then buy and sell bitcoin on Mt. GOx. Now these geeks have become billionaires
3. Market brewing stage: the price of bitcoin was $13 at the beginning of 2013, but on March 18 of the same year, the government of Cyprus closed the bank and stock market e to the financial crisis, which made the price of bitcoin soar, and the highest price rose to $266 in April. On August 20 of the same year, the German government confirmed the currency status of bitcoin. On October 14, China network announced the opening of bitcoin payment channel. In November, the US Senate hearing also confirmed the legitimacy of bitcoin. On November 19, the price of bitcoin rose to US $1242, forming a new high. Nevertheless, the foundation for blockchain to enter the mainstream social economy is not yet available, and the soaring price of bitcoin is only e to over optimistic expectations. The containment of China's banking system, the collapse of Mt. GOx and other events made the price of bitcoin continue to fall. At the beginning of 2015, the price of bitcoin has dropped below $200. From 2013 to the beginning of 2015, the public began to understand bitcoin and blockchain
4. The mainstream period of blockchain: on June 23, 2016, the United Kingdom left the European Union, the fifth nuclear test of North Korea in September, Trump's election in November and other events, the uncertainty of the world's mainstream economy led to the recovery of bitcoin with the function of risk aversion. The market demand was large, and the increase of trading volume made the price of bitcoin soar from $400 in 2016 to $20000 in 2017, The wealth effect of bitcoin and the transaction overflow caused by network congestion of bitcoin have led to the outbreak of other series of virtual currencies, as well as a variety of blockchain applications, resulting in the emergence of a large number of blockchain assets that are 100 times, even 1000 times and 10000 times, which has aroused the crazy pursuit of the world, Subsequently, the Chicago Mercantile Exchange launched bitcoin futures trading, marking that bitcoin has officially entered the mainstream investment proct series, and bitcoin and blockchain have entered the global attention
5. Instry landing stage: after the market frenzy in 2017, the virtual currency and blockchain have been adjusted in terms of market, supervision, cognition, etc. in 2018, returning to rationality. In 2017, many blockchain projects that follow the blockchain technology will graally die out with the cooling of the market, and the projects with real blockchain applications will be initially implemented. 2018 is not only the first year of the blockchain, but also a gold rush period for the blockchain. After the waves wash away the sand, what remains is relatively good gold
from the perspective of the history of blockchain development, blockchain technology is not yet mature and is currently in the growth period. The specific practical application of blockchain is only used in the financial field. It still needs a long way to go to apply blockchain from other instries. However, we should grasp the trend of blockchain and actively learn from the new field of blockchain.

3.
1. Hardware and infrastructure, the typical miner proction, distribution chain, where you can buy miner, mining to earn money
2. The underlying platform of blockchain and common technologies, such as Ethereum and other public chains, and the privacy protocol nucypher, where you can make money by investing in its token, building applications on the chain, and providing services for users
3. Various vertical applications, such as supply chain traceability and Finance Based on blockchain, right confirmation and trading, can be used or invested to make money
Service facilities, such as digital asset exchange and wallet, media procts, etc., you can make money by making your own exchange
extended data:
the characteristics of blockchain
1. Decentralization
blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain
2. Openness
the foundation of blockchain technology is open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
3. Independence
based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention
4. As people in the instry, what they see is that the waves are sweeping through the sand and the fittest survive. Those unreliable and pure deceptive blockchain projects will die faster in the cold winter. Even if they don't die, they will die. And companies that really have the strength to study blockchain technology will have a greater probability of survival, and then take off in the next bull market
in terms of currency price, the bull market should still be in 2019 as a whole, because bears are long and cattle are short
there will be more breakthroughs and developments in technology and commercial applications in 2019.

5. It's OK. It's known that the reputation is not bad
6. I suggest you go to lieyun finance and economics
blockchain is actually two words, block and chain. Every bill is a block, which is linked together to form a blockchain.
first, at the beginning of bitcoin's operation, Xiaoming was given 200 yuan, and it was stipulated that whoever recorded the account first could get 10 yuan (this is the consensus mechanism, which encourages everyone to agree to do the same thing), Then give you a lot of blank bills, once a transaction occurs, you can fight for bookkeeping
1 one day, Xiao Ming gave Li Si 100 yuan (that's the deal). Then Xiao Ming could roar in the crowd and I gave Li Si 100 yuan (and sign his name). When you hear this, you can fight for bookkeeping.
2 because Wang Wu remembers quickly, he yells in the group when he finishes it first, and I remember well. This is Wang Wu, and he sends the bill to others. Wang Wu remembers very well, and there is no mistake after confirmation (Li Si signed his name), so Wang Wu gets a reward of 10 yuan, Then everyone put the bill on the last page of their books& lt; There can be multiple transactions at a time & gt
3 Wang Wu likes the glory of the king. He always likes a hero, demacia, but it costs 25 yuan, but Wang Wu only costs 10 yuan, which is obviously not enough. Wang Wu starts to think that I can keep my own account. Anyway, I can't see anything from the account book. Soon, Wang Wu got another chance to keep accounts. Besides keeping good records of other accounts, Wang Wu added one. Wang Wu gave Tencent 25 and then announced it in the group
4 while Wang Wu was waiting for demacia, Li Si carefully looked at the bill and found that it was all his own signature, no problem. However, Li Si found that Wang Wu had only 10 yuan to pay for the bill, so he refused. Similarly, everyone refused
5 Wang Wu's plan failed at the cost of wasting a lot of energy without rewards
the above basically explains the process of regional chain,
is the above explanation clear? Do not understand the place, you go to ask, lieyun finance it

7. 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.
