The difficulty of computing power of zcash increases

1.

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. It's only a few thousand yuan, but it's hard to upgrade it later.
if you ask the team to do it, more than 100000 yuan, plus hundreds of thousands of other things, it's safe and easy to upgrade

3. 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.

4. Friends who are new to the currency circle are dazzled to see all kinds of digital currencies. What are the origins and characteristics of these cryptocurrencies? Here is a brief introction to some mainstream cryptocurrencies< Bitcoin is the earliest cryptocurrency. In 2008, an Internet geek named Nakamoto Tsung published a paper called bitcoin: a peer-to-peer e-cash system. In 2009, the first creation block was g up by Nakamoto Tsung and has been developing ever since. The original block size of bitcoin was only 1m, and the congestion problem was getting more and more serious. As a result, the block expansion was put on the agenda. The core development group advocated the use of isolation witness and lightning network to realize the expansion, while the big block group advocated the direct expansion of the block. At last, on August 1, 2017, bitcoin cash (BCH) forked from bitcoin (BTC) and expanded its capacity by expanding the block. After this split, bitgold, bitdiamond, super bitcoin, bitgod and many other split coins have sprung up. Later, BCH itself encountered a bifurcation. The Australian CSW, who calls himself Nakamoto Tsung, has to continue to expand the block and lock the underlying protocol of bitcoin. He claims to make a bitcoin that meets Nakamoto Tsung's vision. This time, the bifurcation coin is called BSV

apart from BCH and BSV, most of the other bifurcated currencies have declined. BTC, BCH and BSV represent the exploration of three different directions respectively. BTC is the most conservative and cautious, BSV is the most radical, and BCH is relatively mild and graal. At present, BTC enjoys the name of bitcoin in fact and has the largest market value< br />
< At the end of 2013, vitalik buterin (V God), a gifted programmer born in 1994, published a white paper on Ethereum, proposing the idea of adding various smart contracts to cryptocurrency, which can be used in social networking, trading, games and other fields. The market value of Ethereum has soared all the way, and it will soon be second only to bitcoin, Ethereum with smart contracts is also known as blockchain 2.0

in 2016, Ethereum encountered a serious hacker coin theft incident (DAO), and God V decided to delete the coin theft record by using rollback method. However, some people who insisted that the blockchain should not be tampered with opposed rollback, so Ethereum also split. Unlike bitcoin, the original Ethereum chain has become a minority, known as the Ethereum classic (etc), and the new chain that has been rolled back has become a majority, the de facto Ethereum (ETH)

stable currency system

stable currency is generally anchored legal currency, which can be used to exchange legal currency 1:1 to the issuer. The currency value is relatively stable, but sometimes there will be a small amount of premium in transactions, which is widely used in cryptocurrency transactions. Now the most common stable currency is the usdt issued by tether company, 1 usdt = 1 dollar. Stable currency is generally issued on other cryptocurrency networks, such as bitcoin Omni protocol, Ethereum erc20 protocol, etc< br />


in anonymous currency

on bitcoin, every transaction is clear and searchable, although we don't know who the person behind the address is. Some people think that the privacy of bitcoin is not enough, so some anonymous coins, such as XmR, dash and zcash, which can cover up user information, have emerged. Monroe coin uses ring signature technology, dasey coin adopts mixed coin technology, and big zero coin uses zero knowledge proof, which can play an anonymous effect in different degrees

platform currency system

some digital currency trading platforms often release their own platform currency, and there are certain discounts for trading with platform currency, such as okb of okex, HT of fire currency, BNB of coin security, etc<

some other mainstream currencies

lightcoin (LTC) has copied the code of bitcoin, replaced the consensus algorithm, and shortened the block out time. When bitcoin wants to upgrade, it often does experiments on bitcoin first. Lightcoin is known as "bitcoin, lightsilver"

XRP is currently the third largest currency in market value. It is an Internet transaction protocol, allowing users to transfer money around the world quickly and cheaply

grapefruit coin (EOS), known as blockchain 3.0 and Ethereum upgrade, attempts to introce more functions and application expansion on it

"bitkangaroo" is the first digital currency financial service platform in the world that allocates theoretical revenue from its own mines and machines without power failure. The platform is mainly based on cloud computing procts, and the theoretical revenue is allocated by "1tash" of Wanyou computing power's professional mine, a strategic partner, on a regular basis every day, integrating high-yield, security, liquidity, transparency and professionalism

High Yield: the platform aims at "increasing users' assets", and customers can choose a variety of derivatives to prevent systemic risks

Security: the team stores the standby digital assets in the cold multi signature wallet, and in case of any accident, the reserve fund will be used to distribute revenue to customers

Liquidity: the platform allocates income every day, and can withdraw as soon as it reaches the minimum currency withdrawal standard

transparency: mine data and mine logs are open and transparent, and users can monitor the actual computing power of the mine at any time through the data center monitoring system

Professional: the mine is operated and managed by professional personnel who have been engaged in deep mining for many years. Each unit is isolated by professional network interruption to prevent virus invasion. Multiple standby networks are used in the computer room to eliminate non systematic risks in an all-round way

1. The supply model of Zec is very similar to that of bitcoin - it also has a fixed and known distribution model

The miner needed for digging Zec coins is simpler and cheaper

3. Zec started late and has a bright future

6. 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.

7. 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.

8. Domestic zcash currency trading platforms include lianxing.com, yuanbao.com and yuncoin.com.
