At 3:26 pm (UTC) on July 30, 2015, the first creation block of Ethereum was born. In the entire life cycle of Ethereum, code iterations are also going on at the same time to improve system performance, which is mainly divided into four Two stages: Frontier, Homestead, Metropolis, and Serenity. The first three stages of Ethereum consensus algorithm use proof of work (POW), anBitcoin mining hardware 2016d the fourth stage plans to switch to proof of stake Mechanism (POS).

The asset side of central banks in developed countries is mostly bonds. Central banks in developed countries issue currencies by purchasing treasury bonds as basic assets. Developers’ asset sides are mostly foreign exchange reserves. For example, they earn US dollars through exports and central banks buy US dollars as basic assets to put money into. In the reserve assets of all countries, gold accounts for a small amount.

Urban life needs a new order. There are rulers who are responsible for sacrifices and wars. There are also the ruled, mainly farmers, and some are handicraftsmen, civilians, and businessmen. Everyone began to divide labor. Some people no longer need to produce food, and they need to rely on the ruler to redistribute to support them.

In 2019, it is expected that major economies around the world will substantially implement counter-cyclical control, and easing monetary policy is the first choice. In addition, more proactive fiscal policies can be further expected. As the most likely to have a crisis, it has been in the forefront of the world in this countercyclical adjustment, and intensive policies have been introduced since the fourth quarter of 2018.

And DPOS does not stop there. BM and his team are still supplementing and improving the consensus mechanism. On May 3, 2018, in the eos.io0 version, BM strengthened the DPOS consensus loss problem caused by the last irreversible block.

In addition, in June of this year, William Hinman, head of the financial department of the US Securities and Exchange Commission (SEC), once stated that setting aside the fundBitcoin mining hardware 2016raising activities related to Ethereum, according to his understanding of the current status of Ethereum, the network and its decentralized structure, the current Ethereum’s Issuance and sale are not securities transactions. William Hinman may reflect the SEC's attitude to some extent, which bodes well for the Chicago Board Options Exchange.

After that, Amaury Séchet, the lead developer of Bitcoin Cash (BCH), was kicked out by the BCHSlack community. According to many sources, he bluntly expressed his preference for a pre-consensus solution, which is an organized solution that reduces orphaned blocks by reaching an agreement with block miners speed. However, this proposal was opposed by other members of the community, especially Craig Wright who claimed to be Satoshi Nakamoto.

Observers supporting regulation in Australia believe that the mandatory registration of cryptocurrency exchanges will provide more legitimacy for digital currency companies and blockchain projects. Phillippa Ryan, a cryptocurrency researcher at the University of Technology Sydney, told the Australian Broadcasting Corporation that regulation helps deprive low-quality and unreliable operators from the legitimacy.

One of the main motivations that motivated me to write this article was to identify a major misunderstanding, that is, Bitcoin's access to users' access to communication rights is different from the strong static guarantees it promises to users. As mentioned above, censorship will only occur during the spread of Bitcoin, so censorship resistance cannot be regarded as a characteristic of Bitcoin in an idle state.

However, these statistics of CoinDance are not the final result, but based on the current computing power support. There are still a few days before the Bitcoin Cash hard fork activation on November 15th, and the future computing power situation may change. Miners can still change their positions. If BitcoinABC cannot reverse the situation, BitcoinSV will receive more than 50% of miners' computing power support at the time of the fork, and ABC will drop to 20% or even lower, as will BitcoinUnlimited. Nodes that do not undergo network upgrades will receive 5-6% computing power support and become the least feasible chain after the fork.
