Current situation of Ethereum
as long as you invest in TBCC, you don't want to come out and cut your leeks immediately when you come out, In fact, it's a capital disk. At the beginning, you were constantly allowed to develop offline in order to make money. The result of offline development is to let everyone recharge. It's just a new way of recharge. In order to avoid the supervision of capital, you will be allowed to recharge the digital currency usdt. So it's a capital disk of money. If you don't believe in it, you can ask the online people carefully how to dect the service charge and whether it can be paid at any time, They don't dare to use platforms other than their own to publicize. All the introctions and lessons are on their own platform, because it's easy to be sealed up and punished by law on other platforms. They will only tell you that if you want to make money, you should study hard on the platform. Therefore, we must see clearly and don't be fooled, If he can mention that your own bank card is OK, the card they give is meaningless. They can't say they won't let you mention it. They can control it
Eth is the Federal Institute of technology of Zurich, located in Zurich, Switzerland. It is a world-renowned top research university. For many years, it has ranked first in European universities and enjoys the reputation of "the first university in Europe". It ranks sixth in the world in the comprehensive ranking of QS World Universities in 2020
The Federal Institute of technology in Zurich was founded by the Swiss Federation in 1854 and began to teach as a technical college in 1855. Initially, it consisted of six faculties of architecture, civil engineering, mechanical engineering, chemistry and forestry, as well as an organization integrating mathematics, natural sciences, literature, social sciences and politicsthe Federal Institute of technology of Zurich ranked 9th in the world in the 2016 QS World University comprehensive ranking; In 2017, QS ranked the eighth in the world; Ranked 10th in the world in the comprehensive ranking of QS World Universities in 2018; Ranked 7th in the world in the comprehensive ranking of QS World Universities in 2019; In 2020, QS ranked the sixth in the world

the development status of eth
the Swiss Federal Institute of technology was established by the Swiss Federal Government in 1855 for the needs of national instrialization, which is a Federal University. It is not only for its own development, but also for the whole country, Europe and even the world to engage in scientific research. At the beginning, the university only had civil engineering, forest science, mechanical engineering and chemistry, and then added humanities, sociology and political science
the school has 26000 teachers and students from more than 100 countries in 16 departments, and its teaching and research fields include architecture, engineering, mathematics, natural science, social science and management science. For eth, the number of students enrolled and tuition fees are not considered at all. With the support of the federal government, the college receives as much as 9.2 billion Swiss francs a year for ecation, which does not include the use of property management and new teaching facilities
the college has also received up to 3 billion Swiss francs from third-party funding and its own technology transformation. All these funds are used for school running and scientific research, or most of them are directly used for more than 20000 students and 500 professors (full-time equivalent personnel of more than 9000 person years)
Even so, ETH continues to say that it is short of money in its annual reports in recent two years, and the reason is very simple. In order to compete with other institutions (universities), our independence is the most important, so we need a long-term sustainable financial supportlast year, we expanded the enrollment of 4% of the students. At present, the number of students is 156% of that ten years ago, the number of professors has increased by 23%, and the number of scientific research personnel has increased by 53%. However, the government's scientific research funding has only increased by 42%, and the available area for ecation has only increased by 7%. We are facing great challenges
However, it is not surprising in Switzerland. Due to its unique ecation system, all resources in Switzerland are concentrated in 10 universities and 2 federal polytechnics. In other words, there are only 12 universities at the level of higher ecation, and the country is not short of money, so the current situation is formedafter Ethereum is upgraded to version 2.0 POS mechanism, miners may switch mining machines to other networks
as Ethereum is finally ready to start its Ethereum 2.0 upgrade later this year, thus eliminating the long-term delay, the network will start to move towards the proof of rights model
therefore, the network will give up the workload proof consensus algorithm, so that eth miners have little choice. As their equipment will become obsolete, they will be forced to start mining counterfeit coins or re qualify as eth mortgagors. So, what is the current situation of Ethereum mining? With the coming transition, what will happen to the whole instry< At present, Ethereum consensus is based on POW system, which is similar to bitcoin (BTC). As a result, Ethereum's mining process is almost the same, as miners use their computing resources to earn rewards for each block they try to complete< However, there are still major differences between these processes. Although bitcoin mining has relied almost entirely on ASIC (large, loud machines designed specifically for cryptocurrency mining, most of which are concentrated in areas with low electricity prices), Ethereum's pow hash algorithm ethash is designed to support global chip manufacturers (such as NVIDIA and AMD). As Thomas Heller, global business director of cryptocurrency mining pool f2pool, explained in a conversation with cointegraph, GPU is much cheaper and easier to access than ASIC
"as ASIC is a very professional machine, when a new generation of procts is released, it is usually a huge technological leap. As a result, they have a much higher hash rate and are more energy efficient than the previous generation. This means that those manufacturers have spent a lot of money to research and develop it. Their machines are usually very expensive, and GPUs are much cheaper. "
Heller added that those who use GPU miners "have more flexibility to mine." For example, the popular NVIDIA geforce GTX 1080 Ti card can mine more than 15 different currencies, while ASIC units usually support only one currency
nevertheless, Ethereum is not completely immune to ASIC miners - at least in its current state. In April 2018, bitcontinent released antminer E3, an ASIC specially proced for mining Ethereum. Although widely praised for its hash rate of 180 megahashes per second and power consumption of 800 watts, it has received different responses from the Ethereum community. After the ASIC is inserted, a considerable number of GPU rig owners seem to suffer from loss of profits, and some are even forced to switch to other networks
"in the white paper, ETH must have ASIC resistance. I would like to say that the white paper stands for something "is one of the highest comments on the AR / ethermining topic about the topic discussed when antminer E3 was announced. Another reddit user argued that "the $800 only applies to 180mh."“ Split or die of a nation. "
some Ethereum users continue to suggest that bitmain's mining devices can lead to greater concentration, thus increasing the possibility of attack by 51%. Soon, a group of developers put forward "programmed workload proof" or progpow, which is an extension of the current Ethereum algorithm ethash, aiming to make GPU more competitive and promote decentralization
according to a paper published in March by Kristy Leigh Minehan, co-founder of progpow, about 40% of the hash rate of Ethereum is generated by bitmain ASIC. Alejandro de la Torre, the vice president of poolin, is the sixth largest pool of eth. He confirmed to cointegration that "GPU mining is still dominant" in Ethereum network, and added:
"at present, the profit of eth mining is not high, and the management threshold and cost of GPU equipment are higher than ASIC equipment. Compared with ASIC devices, GPU devices are more flexible, and you can use other algorithms to switch to other coins. "
progpow has not been integrated into Ethereum, and it is not clear when it will be finally implemented - in March, Ethereum core developers were debating whether progpow will really benefit the network in nearly two hours, and failed to reach a consensus. It is worth noting that a bitmain representative has previously told cointegraph that the mining hardware giant does not intend to extend the service life of antminer E3 to start operation after October 2020: "as far as we know, mining will end in October or some time after that."
a safe but uncertain future
indeed, Ethereum will stay away from mining in the future. Ethereum 2.0, which is planned to be launched later in 2020, is a major network upgrade on the blockchain, aiming to transfer its current POW consensus algorithm to a virtual POS (known as "block verifier")
more specifically, users are randomly selected considering their wealth in the network or their "interests". In other words, the more coins a POS verifier chooses to put in, the more coins accumulated as a reward
according to vitalik buterin, the co-founder of Ethereum, e to the transition, the network will be more secure and the attack cost will be higher than the network of bitcoin, although the debate about the better consensus algorithm in the encryption community has lasted for many years. However, it is not clear when to start Ethereum 2.0, as many errors and management issues are reported to be delaying the process
another hypothetical benefit of POS system is that it has higher energy efficiency than pow blockchain. According to digiconomist, the cryptocurrency's total annual footprint is 59.31 terawatts per hour, which is comparable to the electricity consumption of Greece as a whole. However, since a report in July 2019 estimated that 74% of the exploitation of bitcoin was done using renewable energy, the environmental impact of bitcoin does not seem to be so serious
what will happen to the actual Ethereum miner? According to the documentation of Casper upgrade as part of Ethereum 2.0 roadmap, the network will initially support a hybrid model including both POW and POS, thus providing some space for block verifiers and GPU / ASIC miners. Jack O & 39, CEO of skale network; "There will definitely be a transition period when two networks are running at the same time," Holleran told cointegration The CEO of scale network (based on Ethereum's blockchain platform) gave a detailed description of this process:
"the transition from eth1 to eth2 takes time of course - it may be years rather than months. The good news about this slow transition is that dapps and defi platforms will be able to roam around based on survivability, security and real-world evidence of adoption. This is a positive impact on the Ethereum ecosystem. "
dig or not
once Ethereum is fully in the POS orbit, miners will have two options. One is to sell the equipment and use the money to accumulate more Eth and start mortgage. The other is the choice for GPU miners, which is simply switching to other ethash networks and mining counterfeit money. Nick foster, a representative of kabombacks, a US mining equipment dealer, told cointegration that most eth miners would choose the latter:
"what I want to say is that most of the miners have not really entered Ethereum or the mining of specific tokens. Yes, there is a certain amount of mineral deposits and holds, but I oppose the view that a large number of Shanzhai coin miners hold their coins at any time. "<
foster then described how he used 3gb GPU units to mine ethash's point-to-point blockchain asset ravencoin (RVN). Once it was unable to mine eth, he said, "this is the reason for mining crows. I immediately sold stability to BTC, and then sold it to US dollars to pay for my rights. I would say that a lot of people are adopting this strategy. "
as foster concludes, he wants eth miners to jump out of the network, and new players - those who don't invest in power infrastructure or drilling rigs - will take a stake in eth. He described the following:
"I can't imagine if I found a five-year lease with $0.04 of electricity and I was mining eth, I decided to sell everything and then continue to pay the rent so that I could hold eth as a share. Substitute. "
Marc fresa, founder of asic.to, a mining firmware company, agreed in a conversation with cointegraph: "if you invest in mining, you won't bet because you have enough room to grow."
one of the main counterfeit coins that may benefit from POW miners leaving Ethereum is Ethereum classic (etc), which is a more conservative version of the blockchain. It is reported that there is no POS related plan. As it also runs on the ethash algorithm, the startup of Ethereum 2.0 may lead to the migration of miners, so its hash rate may have a significant peak
eth's larger pools have similar options. When asked about the company's plans for Ethereum after pow, Heller told cointegraph that after the announcement of Ethereum's POS upgrade, f2pool launched a sister company called story.fish in early 2018. Story.fish has started to provide mortgage services for other POS and delegated POS projects, such as tezos (xtz), Cosmos (atom) and Cardano (ADA), e to numerous handover delays. For prin, e to the transition to POS, it "may temporarily give up supporting eth mining," de la Torre told cointegraph
other top eth pools, namely nanopool, ethermine, pool center, sparkpool and spiderpool, did not respond to requests for comment from cointegraph.
Bitcoin is not gambling
At present, Atari will launch an encrypted casino in the Ethereum based virtual world{rrrrrrr}
Atari, the game company behind the iconic Pacman, asterioids and Pong, will cooperate with decentral games to develop an encrypted currency casino
according to a press release shared with coindesk on Monday, Atari casino will be built in Vegas City, the game area of the virtual space in Ethereum's decentraland, and will be leased for the first two years
in the virtual world, players live in the avatar's body when interacting with the digital world or "meta world". Decentral games, a part of decentraland ecosystem, claims to be the first community-owned Yuanjie cryptocurrency casino
according to the press release, token holders of DG will also be able to use them to participate in governance and company related decisions
"by working with decentral games, we can transfer Atari's game experience to the blockchain," Atari CEO Frederic Chesnais said in the announcement
Decentraland is supported by digital currency group, the parent company of coindeskto put it simply: if you are only the holder of eth, you don't need to make any preparation for this upgrade.
Bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items
bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals
2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the federal government of the United States, hoping that relevant institutions would pay attention to the status quo of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
3. On May 12, 2017, a global outbreak of bitcoin virus madly attacked public and commercial systems! Nearly 74 countries in the world have been seriously attacked
4. From August 1, 2017, global bitcoin trading platform will suspend recharge and withdrawal services. Bitcoin China digital asset trading platform will stop new user registration on September 14, and all trading businesses will be stopped on September 30
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software was designed and released, and P2P network was built on it. 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 to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, And the use of cryptography design to ensure the security of all aspects of money circulationthe decentralized feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
the ultimate goal of Ethereum is not to create some kind of "currency", but to become an excellent underlying protocol that provides a powerful Turing complete scripting language, on which any high-level contract, currency and other decentralized applications can be created. With Ethereum, those who come up with ideas that may greatly change the current situation of currency application will no longer need to start their own blockchain. They can simply use Ethereum script coding to realize their ideas. In short, Ethereum is a basic platform for innovation of district centered language. The core technology behind bitcoin is blockchain technology. Adding "smart contract" to the blockchain is Ethereum
blockchain is an indestructible digital ledger, which can be set not only to record financial transactions, but also to record almost all valuable information without fear of tampering. In the simplest model, blockchain is a simple distributed ledger. However, the internal meaning of blockchain is far greater than the surface meaning of its name. Blockchain can transfer the value itself in the process of transaction. As Sally rivers, a technology author of the financial times, said, in terms of bitcoin, blockchain means the same to it as Internet means to e-mail
similar to e-mail, blockchain helps to transfer wealth. Blockchain technology is rapidly exploring and deploying in many fields, including capital market, financial services, payment and remittance, derivatives trading, credit management, government governance, sharing economy, supply chain, audit, stock trading, Internet of things, insurance, health care and so on.
