Ethereum POW to POS plan time
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 numbersextended 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
What does this mean? That is to say, how much money you get depends on the effective work you contribute to mining. In other words, the better the performance of your computer, the more money you will be allocated. This is to allocate money according to your work certificate. Most virtual currencies, such as bitcoin, Leyte and Ruitai, are based on the pow mode (the higher the computing power and the longer the mining time, the more money you get)
pos: proof of stake
What does that mean? In short, it is a system to pay you interest according to the amount and time of currency you hold. In the POS mode of certificate of equity, there is a term called currency age. Each currency has one currency age every day. For example, if you hold 100 currencies for 30 days, then your currency age is 3000. At this time, if you find a POS block, Your currency age will be cleared to 0. Every time you are cleared 365 coins, you will get interest of 0.05 coins from the block (which can be understood as 5% annual interest rate). In this case, interest = 3000 * 5% / 365 = 0.41 coins, which is very interesting. Holding coins has interest, very good!
first of all, the topic is not right. Now there are all kinds of currencies on the exchange, whether it's big platforms like Qube, or small ones like coin an, or competitive ones like Shanzhai coins. They are not all POS models
for example, LTC is a variant of crypt algorithm pow, dogcoin is a variant of pow, and auxpow is a fusion mining algorithm
Dashi coin is the pow of X11 algorithm, Ethereum is the pow of ethash algorithm, and Diandian coin is the pow + POS simultaneous mining. Now the new Shanzhai coin is mostly the early POW + late POS mode, the reason is 1, the early POW is to avoid uneven distribution. 2. In the later stage, POS can't win in the pow competition, but the computing power is low, and POW is easy to be attacked by 51
that is, only from the perspective of security: high computing power pow (including auxpow like dog coin) & gt; POS> Low computing power pow
If you forget the stock capital password and transaction password, there is no other way, you can only bring your ID card, shareholder account card and other relevant materials to the securities counter. For specific questions, you can consult the customer manager
stock account refers to the account opened by investors in securities companies for stock trading
opening a stock account is a prerequisite for investors to enter the stock market
precautions for opening stock account
(1) required certificate: ID card. If a legal person's stock account is opened, the original (or ) of the business license and the power of attorney of the legal person shall be issued at the same time
(2) fees include: application form fee and account opening fee(3) operation process: investors need to fill in the application form and pay the handling fee; Hold relevant certificates, application forms and receipts of account opening fees to the account opening counter and hand them to the counter undertaker; After the undertaker checks the above materials, the applicant takes back the relevant certificates and receipts and gets the stock account card
extended information:
stock account loss reporting and re handling
(1) Shenzhen securities account loss reporting and re handling
1. If an investor loses his securities account card, he / she can report the loss and re handle the new number of securities account at Shenzhen Branch of China Securities Regulatory Commission or its designated securities business office with his / her ID card
2. If the investor loses the securities account and ID card at the same time, he / she should report the loss and go through the replacement proceres with the ID card loss certificate, account book and its issued by the public security organ
3. If the investor entrusts others to report the loss, the agent should present the legal notarization document at the same time
(two) the loss of the securities account in the Shanghai Stock Exchange and the replacement of the
securities business department will apply for the loss of the securities account according to the following proceres:
1, carefully examine the identity card of the investor (for example, if the identity card is lost at the same time, it must provide the certificate of loss of the body certificate issued by the public security police station under the registered residence, and paste the official seal of my recent certificate); p>
2. All securities in the securities account will be frozen
3. After the investor provides a new securities account with the same securities account registration information opened by the agency of Shanghai Securities Central Registration and Clearing Company, the corresponding securities account transfer proceres shall be handled for the investor
(4) after the securities business department has accepted the transfer of investors' accounts and registered their securities subsidiary accounts, it will send the change information to Shanghai Securities Central Registration and Clearing Company for change registration before the closing of the market on that day5. The securities business department can handle the application for investors to cancel the loss report, but the securities account that has gone through the proceres of securities transfer can not cancel the loss report
6. When the securities business department accepts the loss report of investors' securities accounts, the Shanghai Securities Central Registration and Clearing Company will change all the securities rights and interests in the loss report account to the account of the transferor at one time
Harbin miners, a key mining, Alipay can also be withdrawals, thieves are convenient. p>
2. POS is the proof of rights and interests of POS, which is an upgrade consensus mechanism of pow; According to the token proportion and time of each node; It can rece the difficulty of mining in equal proportion, so as to speed up the speed of finding random numbers. In a word: the more you hold, the more you get. POS is capitalism, distributing according to money, money makes money
3. I read the news a few days ago that God V wanted to solve this problem. Pgpow algorithm is proposed by biut public chain. Polling group proof of work integrates the advantages of POS and POW consensus algorithm to realize decentralized POW mining.
