POW: full name of proof of work

pos: proof of stake

both of them are the consensus mechanism of blockchain and the bookkeeping method of digital currency

the difference is:

1. POW mechanism: workload proof mechanism, that is, the proof of workload, is the requirement that must be met when generating a new transaction information (that is, a new block) to be added to the blockchain. In the blockchain network based on workload proof mechanism, the ability of nodes to obtain the correct numerical solution to generate blocks by calculating the numerical solution of random hash hash is the specific performance of node computing power

POS mechanism: the proof of rights and interests requires the certifier to provide a certain amount of ownership of cryptocurrency. The operation mode of the proof of rights and interests mechanism is that when creating a new block, the miners need to create a "currency right" transaction, and the transaction will send some coins to the miners themselves according to the preset proportion. According to the proportion and time of token owned by each node, the equity proof mechanism reces the mining difficulty of nodes proportionally according to the algorithm, so as to speed up the speed of searching for random numbers

extended materials:

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction

2. Yes
the advantage of the video card miner is that it can dig other coins after one coin is collapsed. AISC mining machine is more efficient, but it can only dig a single currency.

3. Bitcoin is a kind of virtual currency with more investment in recent years, similar to this kind of virtual currency. In fact, there are many kinds. If you want to really think it has investment value, you need to consider it carefully.

4. Constellation badge can be obtained by mining and doing tasks]
Aries clothing = constellation badge + sheep BAABAA (sheep Baa Baa is bought in the mall, gold coins × 20)
Gemini clothing = constellation badge + double row chocolate (double row chocolate can be mined). Pure guess luck)
Leo clothing = constellation badge + love gift box (love gift box mining can get, also can buy from players)
Virgo clothing = constellation badge + snow wool (snow wool can raise sheep, also can buy from other players)
Taurus clothing = constellation badge + Taurus (Taurus can buy in the mall, gold coins) × 2)
Scorpio clothing = constellation badge + Blue Crystal (blue crystal can only be obtained by mining)
Sagittarius clothing = constellation badge + Cupid's arrow (Cupid's arrow can be purchased from other players or sent by your boyfriend / girlfriend)
Capricorn clothing = constellation badge + wool (wool can raise sheep by itself, You can also buy it from other players)
Pisces costume = constellation badge + Aquarium (aquarium can go to mine, open treasure box and buy it from other players)
Aquarius costume = constellation badge + Black T-shaped water pipe + black straight water pipe (two items can be purchased from other players through mining)
I have finished this task for Libra costume and cancer costume. So I forgot what I needed.

5. At present, mine accidents generally refer to coal mine fatalities, so it is coal mine workers who are killed in mine accidents, of course, including coal mine management personnel. In 2010, there were four fatalities in my city, each of which was one person. As a result, it happened that every time it was the head of safety supervision section. I graated from the coal school, and my classmates and alumni have also sacrificed in the mine.
