Can blockchain currency be bought

The explosive blockchain gives people unlimited fantasy. When many people think about the benefits of blockchain, one of its problems has aroused people's concern, that is, security. Some time ago, 360 discovered a high-risk vulnerability in the blockchain, which can control all the nodes on the EOS. We all know that 51% of the nodes in the blockchain can tamper with the data, let alone 100%. Let's see what's going on

As of May 2020, blockchain and digital currency are illegal in China

according to the announcement of the people's Bank of China Central Network Information Office, Ministry of instry and information technology, State Administration for Instry and commerce, China Banking Regulatory Commission, China Securities Regulatory Commission and China Insurance Regulatory Commission on preventing the risks of token issuance and financing, Article 2 no organization or indivial shall illegally engage in token issuance and financing activities. Organizations and indivials that have completed the token issuance and financing should make arrangements such as refund, reasonably protect the rights and interests of investors, and properly handle risks. Relevant departments will seriously investigate and deal with the activities of token issuance and financing that refuse to stop and the illegal behaviors in completed token issuance and financing projects

Article 3 strengthen the management of token financing trading platform

from the date of this announcement, any so-called token financing trading platform shall not engage in the exchange business between legal currency and token and "virtual currency", and shall not buy or sell token or "virtual currency" as a central counter party, and shall not provide pricing for token or "virtual currency" Information intermediary and other services

extension data

"illegal financial institutions and illegal financial business activities ban" stipulates that:

eleventh, the criminal suspect, funds and property involved in illegal financial institutions and illegal financial activities, and the public security organs shall take compulsory measures according to law to prevent suspect from escaping and transferring funds and property. p>

Article 12 the people's Bank of China shall, after investigation and confirmation, make a decision to ban the illegal financial institutions and financial business activities, declare them illegal, order them to stop all business activities, and make an announcement

The first is the equipment level

the equipment level of adverse water cold is from low to high: white yellow green blue red purple orange

the equipment parts that belong to attack category are: weapons, necklaces, rings, bracelets

the equipment parts that belong to defense category are: helmets, clothes, shoes, belts, hand protectors Wristbands

among them, bracelets, necklaces and wristbands cannot be strengthened

[relationship between the number of equipment entries and grade]

Blue equipment can have 2-4 entries

Red equipment can have 3-5 entries

purple equipment can have 4-6 entries

Law of heavy section of equipment 1 [Law of heavy section of equipment parts]

equipment heavy forging of two identical parts, 100% get the same part

Ring + ring = ring

two different parts of equipment re forging, The two parts are 50%

knife + shoes = 50% knife / 50% shoes

Law of heavy section of equipment 2 [rule of heavy section of number of entries]

number of entries: depending on the quality of two heavy section equipment

purple + purple (heavy section): number of entries = 4-6

Red + Red (heavy section): number of entries = 3-5

Blue + blue (heavy section): number of entries = 2-4

Red + purple (heavy section) : number of entries = 3-6

Blue + purple (heavy segment): number of entries = 3-5

Blue + Red (heavy segment): number of entries = 2-5

Law of heavy segment of equipment 3 [Law of heavy segment of equipment level]

level 60 + level 60 (heavy forging) = level 60

level 50 + level 60 (heavy segment) = probability level 50 / low probability level 60

two pieces of equipment differ by more than 12 levels, The level of the newly synthesized equipment will be higher than that of the original low-level equipment and lower than that of the original high-level equipment; You can use this method to upgrade the equipment level

Law of heavy section of equipment 4 [Law of heavy section of equipment quality]

Red + Red = red

Red + Purple = probable rate red / small probability purple

Red + blue = probable rate Blue / small probability red

purple + blue = red

Blue + refined purple = red / common Purple / minimum probability refined purple

popular science of concept

[washing entry]

suppose that equipment a has entry 1 + entry 2, and equipment B has entry 3 + entry 4, Equipment a + equipment B will become equipment C (the entry of equipment C will become a random combination of entry 1 to entry 4)

[control variable method to wash equipment]

if entry 1 of equipment a is what we want, entry 2 is what we don't want; If we want entry 3, we need to find a piece of equipment (dog food) with the same part, the same level and the same level of entry 3 to match with the equipment a; There is a chance to synthesize a piece of equipment with both entry 1 and entry 3

control other variables unchanged, only change the entry, then wash the entry; Similarly, control other variables unchanged, only change the level, it is called wash level

entry washing case:

Many friends are unfamiliar with bitcoin's computing power, bitcoin's mining machinery, mines and mining returns. Let's take a look at the operation mechanism between bitcoin and blockchain records in detail. First of all, what is blockchain? We can think of it as a distributed ledger and a corresponding credit network. In this network, everyone's behavior can be recorded on the chain, and it supports verification and retrospective investigation. Multiple chains are combined to form a block. We call it a miner who is responsible for recording this information on the chain

so, seeing here, I believe you can understand what is bitcoin's computing power and what is bitcoin's mining? In addition, the current mines are basically monopolized by large institutions, or the so-called entry threshold is very high. There is no investment of several million yuan or tens of millions of yuan. Basically, they are retail investors in the current bitcoin mining instry, and retail miners often give up mining because of the large fluctuation of computing power and the rise of electricity cost< br />

Below 63 layers of the ground, it needs to be excavated with stone pick. There are many holes below. First, make some ladders and start to dig down. Dig a grid and put a ladder to climb up. Iron ore and coal are almost the same length. Pay attention to distinguish. It's easy to find in the natural mine, but the natural mine is very dangerous, at least a suit of iron, bow and sword in hand can be safe
