Ethereum energy coin is not MLM
Ethereum is an open source public blockchain platform with smart contract function. Ethereum provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency Ethereum
in 2013, vitalik buterin, 19, first mentioned the idea of Ethereum in a book entitled "Ethereum white paper: next generation intelligent connection and decentralized application platform". Then, in 2014, the algorithm and protocol of Ethernet coin were officially implemented, and $150 million was raised. The system itself was finally completed on July 30, 2015
as the representative of blockchain 2.0, the mainstream currency Ethernet is regarded as the wind vane of crypto digital currency market. However, over the past week, the price of ether currency has continued to fall. On August 14, 2018, the ethereal currency plummeted by 20%, reaching a record low of $257 this year. Compared with this year's peak of $1295, the price of Ethernet currency has shrunk by more than 80%. Affected by this, on August 15, 2018, none of the top ten mainstream currencies in the digital money market was spared, falling across the board, with a number of single day declines exceeding 10%
extended data
Ethereum started planning almost in 2013, and started to implement the project in 2015. Before that, there were many digital currencies imitating bitcoin in the market, and they made various modifications on the basis of bitcoin code. In this way, it is very difficult to develop a new blockchain application, to re deploy a new chain, and then to develop an application on this chain. Using a consensus mechanism of pow alone is a huge maintenance workload. It's like developing an app on a mobile phone and developing the Android system together
after Ethereum comes out, it is equivalent to the underlying operating system of the blockchain. On Ethereum, it is very convenient to develop various dapps without considering the underlying development, and it can also share the computing power and storage of Ethereum. For programmers, the threshold of blockchain development is lowered instantly. The emergence of Ethereum has played a very important role in the development and popularization of blockchain applications. That's why Ethereum is called blockchain 2.0
POW: full name of proof of work
pos: proof of stake
both of them are the consensus mechanism of blockchain and the bookkeeping method of digital currency
the difference is:
1. POW mechanism: workload proof mechanism, that is, the proof of workload, is the requirement that must be met when generating a new transaction information (that is, a new block) to be added to the blockchain. In the blockchain network based on workload proof mechanism, the ability of nodes to obtain the correct numerical solution to generate blocks by calculating the numerical solution of random hash hash is the specific performance of node computing power
POS mechanism: the proof of rights and interests requires the certifier to provide a certain amount of ownership of cryptocurrency. The operation mode of the proof of rights and interests mechanism is that when creating a new block, the miners need to create a "currency right" transaction, and the transaction will send some coins to the miners themselves according to the preset proportion. According to the proportion and time of token owned by each node, the equity proof mechanism reces the mining difficulty of nodes proportionally according to the algorithm, so as to speed up the speed of searching for random numbersextended materials:
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
first of all, the topic is not right. Now there are all kinds of currencies on the exchange, whether it's big platforms like Qube, or small ones like coin an, or competitive ones like Shanzhai coins. They are not all POS models
for example, LTC is a variant of crypt algorithm pow, dogcoin is a variant of pow, and auxpow is a fusion mining algorithm
Dashi coin is the pow of X11 algorithm, Ethereum is the pow of ethash algorithm, and Diandian coin is the pow + POS simultaneous mining. Now the new Shanzhai coin is mostly the early POW + late POS mode, the reason is 1, the early POW is to avoid uneven distribution. 2. In the later stage, POS can't win in the pow competition, but the computing power is low, and POW is easy to be attacked by 51
that is, only from the perspective of security: high computing power pow (including auxpow like dog coin) & gt; POS> Low computing power pow
2. The circulation of next year will decrease 10 times. In theory, X2
3. The current price of eth is 260x4 = US $1040 (upgrade + expected price after proction rection)
ring this period, the return comparison between holding spot and ETF fund is as follows:
1. Holding spot makes 4 times of profit
2. Holding Ethereum ETF fund starts with 12 times of profit, Up to more than 30 times (intelligent position adjustment + fund compound interest calculation)
there is no doubt that the Ethereum ETF launched by bitoffer is the best investment choice!
this may be found from the contract law and the losses caused by violation,
If you forget the stock capital password and transaction password, there is no other way, you can only bring your ID card, shareholder account card and other relevant materials to the securities counter. For specific questions, you can consult the customer manager

opening a stock account is a prerequisite for investors to enter the stock market
precautions for opening stock account
(1) required certificate: ID card. If a legal person's stock account is opened, the original (or ) of the business license and the power of attorney of the legal person shall be issued at the same time
(2) fees include: application form fee and account opening fee(3) operation process: investors need to fill in the application form and pay the handling fee; Hold relevant certificates, application forms and receipts of account opening fees to the account opening counter and hand them to the counter undertaker; After the undertaker checks the above materials, the applicant takes back the relevant certificates and receipts and gets the stock account card
extended information:
stock account loss reporting and re handling
(1) Shenzhen securities account loss reporting and re handling

securities business department will apply for the loss of the securities account according to the following proceres:
1, carefully examine the identity card of the investor (for example, if the identity card is lost at the same time, it must provide the certificate of loss of the body certificate issued by the public security police station under the registered residence, and paste the official seal of my recent certificate); p>
2. All securities in the securities account will be frozen
3. After the investor provides a new securities account with the same securities account registration information opened by the agency of Shanghai Securities Central Registration and Clearing Company, the corresponding securities account transfer proceres shall be handled for the investor
