Ethereum Constantinople bifurcation

1. The network will be upgraded to Constantinople & Petersburg at block height of 7280000. L, Z, b show that it will be upgraded on March 1, 2019 Beijing time. I don't know if the upgrade is successful

2.

The idea of Ethereum was born in 2013. Vitalik buterin ˙ When he was a programmer in the bitcoin community, he suggested to the core developers of bitcoin to develop a language for application developers to facilitate the development of various applications. Bitcoin core developers disagree. So God V decided to develop a new platform for this purpose

V God wrote the white paper of etheric currency in 2013, in which he explained the goal of building a decentralized program. In 2014, we got development funds through crowdfunding, so we developed the Ethernet system< (better digital currency trading platform "currency exchange")

since its birth, it has carried out four hard bifurcations so far

for the first time, in order to adjust the difficulty

released a stable version of "homeland" for the second time

for the fourth time, in order to prevent DDoS and rece weight

there is only the third hard fork, because of the hacker attack, and forced to fork. This is the Dao event

On July 30, 2015, v-god and Ethereum Foundation created the first smart contract platform and designed the Dao Ethereum contract

on April 30, 2016, the Dao smart contract was officially deployed, and the world's largest crowdfunding was completed, reaching an amazing $150 million As an aside, the biggest crowdfunding event in time is EOS crowdfunding, which has reached an even more amazing $5 billion!)

on June 17, 2016, the Dao was attacked by hackers, who stole about 50 million US dollars of Ethernet currency, and the price also plummeted from US $20 to US $15, causing great harm to Ethereum. In order to recover the loss of investors, the community finally decided to hard fork

therefore, on July 20, 2016, at the block height of 1920000, the hard branching was successful, and the new chain is called Ethereum eth, while the original chain is now Ethereum classic etc

3. Ethereum is a kind of virtual currency, fire money network is operating virtual currency, also operating Ethereum, this is the relationship.

4. The bifurcation of Ethereum Constantinople is about to begin. Many people are curious about this bifurcation and are not sure whether they need to be prepared in advance
to put it simply: if you are only the holder of eth, you don't need to make any preparation for this upgrade.

Let me tell you the answer first: No

or don't invest all of bitcoin. Let me give you a brief analysis

first of all, if your principal is a windfall, I suggest you allin invest in bitcoin, which may be several times more when you take it out at the end of this year. There will be another windfall

if your principal is a year-end bonus, you can consider investing half in blockchain and bitcoin

if your principal is your hard-earned money, you must be cautious in your investment, so first of all, it is not recommended that you invest in blockchain

in fact, your question tells me two basic facts: 1. You are Xiao of blockchain / currency circle; 2. You have a little deposit and want to manage money, or you need to make some money

so from my point of view, I don't recommend you to buy bitcoin or make any other blockchain investment, because there is a saying that a person can't make money beyond his cognition, and the blockchain world is beyond your cognition for you, and the coin circle is basically an extension or part of the financial system. And the financial system is the most cruel and ruthless world. When you want to make money, you should also think that there are hundreds of thousands of people, millions of people who have the same ideas as you, so as to drive them into this bloody and merciless market. So you ask yourself, can you make sure you make money

first pour a basin of cold water on you, and then answer your questions seriously. Let's take a look at the historical trend of bitcoin

I feel optimistic that the recovery may come slowly, the Federal Reserve's move may be the beginning of financial release, and the capital market may recover slowly. As a small part of the financial market, the blockchain world may also recover

from the perspective of investment, bitcoin in the blockchain world is not only the genesis currency, but also the mainstream currency that accounts for the vast majority of the total market value at present. Therefore, if you really want to invest in the blockchain world, bitcoin is the best choice

however, please note that from the perspective of professional investment advice, risks should always be shared. Exclusive bitcoin will be taken off by a currency, and it will also fall miserably. So please consider holding other mainstream currencies, such as BoChang coin, which is known as "the last good heart of the blockchain", which is also the most powerful counter trend growth currency in the bear market of the currency circle. For a long time, when the mother of other currencies, including bitcoin, didn't know each other, BoChang was the only currency that was growing slightly, which was a miracle

another example is Ethereum. Although Ethereum's hard fork has been delayed for a long time, the arrival of Constantinople's hard fork upgrade will make Ethereum the most eye-catching star in a short time. At this time, the investment can be regarded as low-level market entry, and you can make a profit by waiting for high-level investment

finally, back to my answer, if you don't even know wave field, bitcoin, Constantinople hard fork and other words, how can you determine whether you can make a sum of money in the world of currency. So this in itself is a very high risk thing

a strange capital market will swallow up all your savings. Although some people get rich overnight, they are a few people after all. If you are sure to invest in the blockchain world, bitcoin can be invested. However, from the perspective of risk sharing, please buy some other mainstream currencies to minimize the risk. Finally, I wish you a happy investment and a big fortune in the year of the pig. Please be cautious in your investment

is to read more about the various currencies or project's white paper. I pay attention to my WeChat official account: "Nanjing block chain" can get thousands of white papers free of charge, so that you will have a better understanding of the chain world. p>

The

Ethereum mining

Berlin hard fork will mark the end of the metropolitan era. This is a key stage in Ethereum's history, which is divided into two stages (Byzantine and Constantinople), including several branches, including Atlantis, Istanbul, and finally reached its peak in Berlin

7. This number is not fixed, because the price of bitcoin is constantly changing. The highest price of bitcoin is more than $19000. At present, the price of bitcoin is around $4000. You can log in to the bitcoin exchange to view the bitcoin market in real time.

8. After all the towers of the first island are closed, there is a sea crossing bridge behind the last tower. You can go to the central island. You can go to the second island through the central island. All the towers of the third island are closed. After all the towers of the last three islands are closed, you can close the larger towers of the central island.

9. Life is like a pool of ckweed, green and green, with a little bit of water color. When there is no wind, it is like a piece of cloth on the surface of the pool, without any wrinkles. It is also like a natural bronze mirror floating in the pool. Among them, there are also several branches that go straight across the surface of the pool. The surface of the ckweed is slightly broken, but it can't be completely cut, which shows its vitality. Weeds and Kingfisher also disturb the surface of ckweed from time to time, and the ripples of fish are inevitable, which makes ckweed more crowded and tense. Strong wind, wrinkled is ckweed; It is weeds that bend their heads; It is Kingfisher that has disappeared for a long time. The wrinkle is only for a moment. When the wind is a little small, Ping's face returns to its original state. After that, it was wrinkled and floating. Sometimes there are fish "visits.". Wind is the devil, weeds are bacteria, but they can't destroy it. After the wind, the surface is still intact - except for a few sundries. This reminds me of Wen Tianxiang's poem "life experience is ups and downs, the rain hits Ping". Yes, life is not like ckweed. There are always disturbances in a quiet life; And the wind and waves contain a peaceful life. The twists and turns of life, it is not the wind ckweed survival, ckweed is to take root in the water, and people are to survive in the world. Bumpy, long life, sighing to the sky, sighing the past life; Praise the Yellow River, praise the Yellow River majestic; Weeping at the grass, weeping grass nobody knows; Standing on the high mountain singing, singing the power of the high mountain; If there is only the tranquility of ckweed and no strong wind in life, then life is a cup of fresh water and tasteless; If there is only Xiaohe's selfishness, the world is frozen everywhere; If there is only the arrogance of Dashan, there is no selfless love in the world... Your own life and your own road are under your own feet and controlled by yourself. life! Duckweed!
