Become an Ethereum and a solid blockchain developer

Consumer privaBecome an Ethereum and a solid blockchain developercy advocacy organization ElectronicFrontierFoundation strategy director DannyO'Brien said that he is worried that the relationship between members of the association may make it difficult for Libra's other digital wallets or other encryption projects with the same vision to compete with it.

Regarding the development trend of the blockchain, Jiang Xuxian, an industry practitioner and founder of Paidun Technology, said that it is foreseeable that after this wave of supervision, some projects with no value support will be eliminated by the big wave, which will bring to the industry in the short term. Greater downward pressure. But in the long run, some value projects that truly provide technology research and development services will settle down and gradually gain social recognition and attention. On the contrary, they will lead the industry to make more breakthroughs in the development of counterfeiting and realizing.

In terms of anonymity, I drew a question mark. To what extent can the central bank's digital currency be anonymous or partially anonymous? Anonymity helps protect consumers' privacy. A certain degree of anonymity is still very important, but this is not me. The focus of the talk. I mainly want to say that central bank digital currencies do not pay interest. Cash does not pay interest, but it has certain transaction costs. For example, it is troublesome to withdraw money from the bank, and it is necessary to count money. In addition, the banknotes may be damaged or lost. Therefore, although electronic money and cash have zero interest, its transaction cost is lower than that of cash, so it can play a role in replacing cash. In this way, the central bank will obtain convenience benefits.

1 In addition, as more and more traditional financial institutions and service providers enter the market, the ecosystem of virtual assets is steadily expanding and becoming more complex, providing services comparable to traditional mainstream financial institutions. For example, many traditional custodians are studying the provision of encrypted custodian services or technological solutions. In order to meet the needs of virtual asset companies, the Big Four accounting firms have extended their service scope to this category. Large-scale insurance companies and insurance brokers are increasingly open to providing insurance protection and services to the virtual asset industry. Furthermore, many traditional financial institutions are studying the use of private blockchains to develop their own cryptocurrencies to facilitate instant and cross-border fund transfers.

On the other hand, in terms of stablecoins, compared with national digital currencies including DCEP, stablecoins dominated by small companies move much faster. Take the stable currency USDT as an example. It was also proposed in 2014, but for small companies, since there are fewer external factors to consider, in the past few years, the ecological development has been very fast-many Friends may not have noticed that USDT has now reached the fourth place in the cryptocurrency market capitalization rankings, second only to BTC, ETH and XRP, and only two years ago, it was ranked above 50.

Throughout the first half of this year (Bitcoin) market was relatively good, and many people think it will rise. Now look, it has fallen to more than 8,000. In fact, today, two months later (December 10), the price of Bitcoin is less than $8,000 ($7374). The difficulty is rising, the incentive is about to be halved, and the price of the currency is not as expectedBecome an Ethereum and a solid blockchain developer-these are the three problems currently facing the mining industry.

An MRI higher than 100 means that the miners sold more than the mining volume and the inventory is consumed, while an MRI lower than 100 means that the miners sell less than the mining volume and stock up on the inventory. The traditional view is that sellers always tend to sell at high prices. Therefore, some investors will interpret MRI readings below 100 as the miners are waiting for the price to rise, so they are hoarding inventory in order to sell them at a high price at a later point in time.
