Ethereum difficulty curve
money, as a measure of transaction value, does not necessarily have value in itself, it can only be used as an intermediate unit of measurement. It's just like China has only RMB as legal tender, that is to say, government guarantee has value. For example, in those war-torn areas, ten jin currency may not buy an egg, which is the reason
back to digital currency, digital currency, until now, no country has recognized it as the currency in circulation of its own country. It seems that last year or the year before last, our country also banned some. In this case, digital currency can only be sold at a price higher than your purchase price, so that you can make money. But digital currency itself does not have any value. Unlike stocks, it is your ownership of listed companies. So if you can't find someone to buy digital currency, it's worthless
the Ponzi scheme in history, the Dutch tulip, when it was the most expensive, a tulip was worth buying a house. When no one bought it, all the tulips rotted. In addition, they couldn't get a potato. Therefore, Buffett said that digital money is a bubble, which is a hoax.
in addition, there is a saying in the stock market that when all the ladies in the vegetable market begin to discuss the stock market, it is the time when the stock market reaches its peak. In my opinion, this also applies to digital currency. When many people are discussing how to make money and how to make a lot of money, the risk has accumulated to a great extent. Most of the time, when the stock begins to fall, many people are still in the previous inertial thinking, thinking that it will rebound soon, and then it will get lower and lower, and they are more reluctant to sell it. This is why many people hold a high position on it
I'm not sure whether it is the highest point of digital currency, but I think that digital currency, which can be issued by anyone, has no purchase value and can only be sold to others. I think it's a fraud.
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
these puzzles
Ethereum is an open source public blockchain platform with smart contract function. It provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency ether (also known as "Ethereum")
The token on theblockchain is called ether, and the code is eth. It can be traded in many foreign exchange markets of cryptocurrency, and it is also the medium used to pay transaction fees and computing services on Ethereum
the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, with the general meaning of "next generation cryptocurrency and decentralized application platform", and began to develop through ICO crowdfunding in 2014. As of February 2018, Ethernet is the second highest cryptocurrency in market value, second only to bitcoin
extended data:
Ethereum platform has no characteristics and value. Like programming languages, it's up to entrepreneurs and developers to decide what to use. However, it is clear that some application types benefit more from the functions of Ethereum than others. Ethereum is especially suitable for those applications that automatically interact directly between points or promote group coordination activities across networks
for example, coordinate the application of point-to-point market, or the automation of complex financial contracts. Bitcoin enables indivials to exchange money without the help of financial institutions, banks or governments. The impact of Ethereum may be more profound
in theory, any complex financial activities or transactions can be automatically and reliably carried out on Ethereum with coding. In addition to financial applications, any application scenario with high requirements for trust, security and persistence, such as asset registration, voting, management and Internet of things, will be affected by Ethereum platform on a large scale
1. Machine cost: the cost of purchasing mining machine
2. Power cost: the power cost consumed by machine mining
3. Auxiliary costs: personnel maintenance, network, cable consumables, heat dissipation, etc.
for a simple example, take the mining machine of ant S9, which consumes less power on the market, for example, the calculation power is 13.5T, and the power consumption is 1400W
when the mining machine runs for 24 hours: 1.4kw * 24 = 33.6 degrees
Shenma m3, which consumes more power on the market, has a calculation power of 11.5t, The power consumption is 2150w
under 24-hour operation, the power consumption of a single machine is 2.15kw * 24 = 51.6oc
which is roughly equivalent to the power consumption of energy-saving air conditioning, but the bitcoin miner needs 24-hour uninterrupted operation, the power consumption of a single machine is very large after a year's calculation, and the step price cost of household electricity is too high, When the market is not good, the income may not be enough for the electricity expenditure, so at present, mining will choose to be hosted in the mine, which can get cheap electricity and rece the cost price of mining. The price below 30% is the ideal price, which can keep the price of bitcoin falling to a low level, and there is still some income< According to the current mining difficulty of bitcoin:
BTC revenue per ton: 1th / s * 24h = 0.00007087btc
calculated by the comprehensive 12t machine computing power, the daily output is:
0.00007087t * 12t = 0.00085044btc
then the time required for a single machine to dig a BTC:
1 / 0.00085044 = 1175 days
the time required for ten mining machines to dig a BTC:
1 / 0.0085044 = 117 days
100 days In other words, according to the current difficulty, it takes about three years for a single miner to proce a bitcoin, 3.9 months for ten miners to dig a bitcoin, and 11.7 days for a hundred miners to dig a bitcoin. The cost of a single miner is about 8500, Ten are around 85000, one hundred is 850000, less than one million, and one month's income is more than two bitcoins. According to the current price of bitcoin, the price is about 120000. So, although the income of bitcoin mining is not as good as before, it is still considerable compared with other investment projects
however, these benefits do not include decting the cost of electricity charges and later maintenance of machines, so the premise of mining is to find a mine with low electricity charges. If the quantity is large, we need to find a safe, reliable and stable mine. What's more, we need cheap electricity to lower the cost price.
compared with bitcoin, we can find that Ethereum is more difficult to develop a new encryption technology than bitcoin. This breakthrough has greatly reced the development cost and time for developers who apply blockchain technology. The emergence of Ethereum once again reiterated the need to split the center, as well as the feasibility and advantages of decentralized distributed applications, to the existing economic market, the financial sector a new direction of development and throw to the society a new entrepreneurial ideas and opportunities.
in terms of cloth storage and mining, I recommend Heshu hardware wallet and jiajiabao intelligent home miner. The core advantage of the proct is safety
take sum hardware wallet as an example. The advantages of sum hardware wallet are as follows:
1. The private key seed is encrypted layer by layer, physically isolated and never touched the Internet.
firstly, when creating the wallet, the seed password is generated and stored in the local encryption chip, and the 10 bit payment password is required
then, the transaction is made in the wallet. At this time, the user needs to enter the payment password to obtain the private key to digitally sign the transaction, and the transaction is completed. In addition, the private key seed is permanently stored in the chip, which is physically isolated and never touches the Internet. There is no need to worry about my password being stolen by hackers
Second, the bank system verifies the financial level motherboard and encryption chipuses the bank system to verify the financial level motherboard, and the private key seed is stored in the chip. If the proct is stolen or lost, and destroyed by malicious violence, the chip will trigger a self destruct circuit, and immediately permanently and irrecoverably delete all the information in the area
Third, it supports the withdrawal of global bitcoin ATM, which is convenient and fastthe reason why digital assets attract the attention of many fields in the world is that it is creating a global fast circulation, and the larger the circulation field is, the wider the scope is, and the higher its use value is. The core of digital assets is the medium it acts on among currencies. The Heshu wallet has built-in many mainstream exchanges in the world. It can trade digital assets anytime and anywhere. With one machine in hand, it can walk around the world without worry, and no longer have to worry about exchanging foreign currency
Different from conventional digital wallets, multi signature wallets need the authorization of multiple key holders to transfer digital currency, so the security of multi signature wallets is higher. Ordinary Wallet: a wants to transfer a bitcoin to X. A only needs his signature (using the private key) to complete the transaction. Sum Wallet: if a wants to transfer a bitcoin to x, a multi signature verification is set (at least two signatures of Abc3 indivials are required to transfer the money), then a needs B or C to complete the signature (using the private key) when a wants to transfer the money to X. I hope I can help you. Thank youThe 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 contracton 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
