When did MC public chain mining go online

1.

In 2009, bencong invented bitcoin, and set that there are only 21 million bitcoins. By participating in the proction of blocks and providing proof of work (POW), he can get the reward of bitcoin network. This process is mining

the concept of "mining" comes from the existing concepts in our real economic life, such as gold mining and silver mining. Because minerals are valuable, it drives people to pay labor to dig

another important point of bitcoin mining is that the miners who participate in mining recognize the value of bitcoin, and some of them are willing to spend money in the bitcoin market. Therefore, the mining of bitcoin is meaningful

currency characteristics of bitcoin

1, decentralized

bitcoin is the first distributed virtual currency, and the whole network is composed of users without central bank. Decentralization is the guarantee of bitcoin's security and freedom

2, bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

3, exclusive ownership

controlling bitcoin requires a private key, which can be stored in any storage medium in isolation. No one can get it except the user himself

4, low transaction cost

bitcoin can be remitted free of charge, but in the end, about 1 bitfen transaction fee will be charged for each transaction to ensure faster transaction execution

5, no hidden cost

as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay

6, cross platform mining

users can explore the computing power of different hardware on many platforms

2. The public chain, as the name suggests, has great inclusiveness and fairness. The better the public chain project does in these two aspects, the more prominent it will be. At present, many public chains sacrifice fairness in order to speed up the transaction, which is not optimistic. There is a project called Fanta network. Their DSC technology claims to be safe, democratic and fair, which deserves long-term attention. However, their code will not be open source until the end of the year, and the progress needs to be accelerated

3. In fact, digital China is based on blockchain. It can be said that the blockchain issue emphasized at the meeting of the Political Bureau of China is the core issue of Digital China.

4. Tcoin is a three body terminator public chain token. It is a cryptocurrency based on three body hard fork network. The total amount of tcoin is 630 million, the initial price is $1, every 10s, and each block proces 8 rewards. The initial mining proced 19620 tcoin per day.

Alibaba has recently launched a virtual currency mining platform "P2P node". According to the terms of the service agreement of the platform, the main operator of the platform is Alibaba East China Co., Ltd. It is reported that the company completed its registration on October 10, 2017, and its registered address is located in Nanjing

at present, we have not yet known the intention behind Alibaba's move. When major platforms generally enter the blockchain ICO market, Alibaba has access to third-party platforms. Compared with blockchain projects with weak data base, Alibaba has accumulated experience to catch up with and surpass the current blockchain technology

6. Thor chain generates one block every five minutes on average, which is the basis of the issuance speed and transaction confirmation speed of Thor. Not only in the short term, but with Odin to ensure that decades must remain constant, ring this period, computer performance will improve rapidly. In addition, the people and computers involved in mining will also change constantly. In order to keep a relatively constant proction rate of new blocks, the difficulty of mining must be adjusted according to these changes. In fact, difficulty is a dynamic parameter, which will be adjusted regularly to achieve the goal of a new block every 5 minutes. In short, regardless of the mining capacity, the new block proction rate is maintained at 5 minutes.

9. Spot silver burst refers to that spot silver investors in the silver investment, the account loss reaches the lower limit of the trading platform, that is to say, the account can no longer lose money, then the system will force the account to close at this time. Then this process is called spot silver burst
in the spot silver trading system, there is a concept of spot silver burst rate, that is, when there is still a lot of margin left in the spot silver investor's account, the system will force to close the position. Of course, different trading platforms have different burst rates, which can be understood by consulting the platform. For example:
suppose that if the burst rate is 50%, the capital of account a is 100 US dollars, and the margin is 10 US dollars. When a loses all 100 US dollars in the account, and even 10 US dollars in the margin is lost by 50%, it will burst, that is, the margin is lost by 5 US dollars
if the burst rate is 100%, when a loses $100 in his account and only has $10 in margin, it will burst.
