Ethereum cannot exchange

1. Note that Ethereum is 2.0 now. As of 13:57 on the 4th, the current deposit contract address of Ethereum 2.0 has received 1000098eth, and 31252 addresses have completed the mortgage of 32eth. With the increasing number of mortgage, the annual yield of mortgage will graally decrease. After the mortgage amount reaches 1 million eth, the current annualized yield is about 15.7%. Zhongyuan, a well-known exchange, has taken the lead in opening the mining channel of eth2.0 verification node, and then launched qeth. Users can invest their own eth in verification node mining and exchange qeth to obtain liquidity, and then participate in mining. Compared with the disadvantages of eth2.0, qeth has too many things: the liquidity is guaranteed, the user does not have to bear the technical cost, the threshold of participation does not need 32 eth as low as 0.1eth, the nodes are maintained by the platform, and the income is distributed according to eth2.0.
2. Ethereum fog, or ETF for short, is a branch chain of Ethereum, which is designed to solve the problem of distributed storage and distributed computing power that Ethereum lacks. In the later stage, it will switch to the hybrid mining of pow + POS. The original coin is ETF

  • after Ethereum bifurcates into etheric fog, the two will exist and develop together< br />

  • 3. With the upgrading of Ethereum to version 2.0 this year, the consensus mechanism will be converted to POS, which will have a huge impact on miners. There are two choices for miners. One is to sell mining equipment and buy eth to adapt to the stacking mechanism of POS; The second is to switch the miner to other networks supporting GPU miner. Nick foster, a representative of kabombacks, a US mining equipment distributor, said most eth miners would choose the latter

    after 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.

    5. It's only a matter of time before companies use monetary incentive software, judging from the issue of virtual currency released by Facebook. Enterprise managers will graally accept new things in this process
    from the traditional monetary incentive is through the current salary incentive, which is effective for short-term incentive, but in the long run, such monetary incentive has no effect. If the currency is changed into a kind of deferred cash currency, this contradiction can be well solved
    the cash currency account is an internal recognized cash account opened by the enterprise for each employee on the teamtoken platform. The corresponding relationship between cash currency and RMB is 1:1. The enterprise can use the unlimited wealth of the enterprise in the future to help the current rapid development and use the unlimited power of the future to ensure the current steady rise by issuing cash currency to employees
    for example, if an employee's salary is 10000 yuan, the enterprise can pay 2000 yuan in cash to the employee every month, and a will withdraw or purchase material benefits at a certain time point in the future (set by the enterprise), so as to achieve the effect of internal and external incentives on the employee without immediately increasing the current cost of the enterprise. This is the innovative monetary incentive for employees
    the creator of teamtoken employee wallet is the enterprise management software cloud (SaaS) with incentive as the core. The core value is to provide each employee with an employee wallet, so that each employee has his own integral account, cash currency account, virtual stock account, option account, enterprise annuity account, etc, It also provides an application ecology with incentive as the core, including team collaboration software, performance management software, CRM software, etc. these software are also the data source of employees' wallets, so that collaboration, performance, sales and other work can reflect the recognition of employees' work in real time, and reward corresponding points, cash, stocks or options, etc, Make management more incentive effect. The navigation and authority settings are clear, multi-functional and in-depth, suitable for large, medium and small enterprises. Open port, which can be embedded in nailing and enterprise wechat. It mainly helps enterprises to motivate employees from the following aspects:
    1. Let every employee have three accounts that dynamically store incentive value
    1. Integral account (quantitative process, recognition feedback) integral account, recognition feedback
    quantitative process, recognition of incentives, points obtained through behavior, task, report, performance, etc., points can be used as the basis for reward, user-defined points standards meet the needs of enterprise personalized points reward, multidimensional points statistics, 360 degree comprehensive analysis
    2. Cash account (reward achievement, medium and short-term incentive)
    enterprises issue digital currency (token) to motivate employees, and cash currency can withdraw cash, purchase benefits, subscribe virtual shares, etc. in the future. It can be applied to performance bonus, Commission Award, special award, year-end award and other scenarios. Cash currency is issued with enterprise credit as endorsement. Enterprises use future funds to motivate current employees<
    consumption right
    employees purchase welfare goods through "consumption right + cash currency" or "consumption right + points", and the consumption right is obtained through rewards
    consumption right is like the "food ticket" in the era of planned economy, which is the key for enterprises to release welfare in a planned way
    withdrawal right
    generally speaking, employees can apply for withdrawal faster with withdrawal right, The enterprise controls the timing, amount and group of cash cash by issuing the right of withdrawal. The management of the right of withdrawal has a great relationship with the cash flow of the enterprise, and it is issued by the enterprise according to its own situation
    subscription right
    only employees holding the subscription right can subscribe for the virtual equity issued by the company. Enterprises control the group, quantity and opportunity of holding the virtual equity by issuing the subscription right. Employees holding the virtual equity are the key training objects. Generally speaking, only employees with long-term incentive can be issued the subscription right
    3. Stock account (talent retention, long-term incentive)
    the purpose of virtual stock is to retain talent (long-term incentive), and the virtual stock corresponds to the dividend right. Employees obtain the virtual equity of the enterprise through enterprise reward or their own subscription of virtual stock, and enjoy the right of weighted dividend every year. Virtual stock can also be used as the pre holding mode of restricted stock of core executives and co founders
    4. Work application tools: get through cash coins and points, and quantify and reward work achievements in time
    task collaboration: task management, quantitative scoring of task quantity, task difficulty and completion quality with comprehensive points
    performance management: get through performance and cash reward
    CRM (to be launched soon): quantify customer management and sales management with points, and reward work performance with cash reward
    blockchain +, Store employee's digital assets in the enterprise
    the enterprise issues cash coins for employee incentive, cash currency account book, record employee's cash coin transfer record and equity registration, which are used as the company's equity register
    welfare mall
    thousands of welfare goods are put on the shelves with one click, and employees purchase benefits through points and cash currency
    it will be a trend for enterprises to use monetary incentive.
