Cheap virtual currency POS node

2. POW: full name of proof of work

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!

3. In line with the rigorous logic of problem-solving, we should first ask whether it is, then why
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

Private key: in fact, it is a group of random numbers. We have already introced the random numbers in the blockchain
public key: the private key is generated by elliptic curve encryption algorithm, but the private key cannot be obtained by public key inversion. The function of public key is to encrypt information with one's own private key when dealing with the other party, and then the other party decrypts the original information with one's own public key. This process is commonly known as signature
address: because the public key is too long and inconvenient to use in the transaction, the public key hash is encrypted with sha256, ripemd160 and base58 algorithms to generate the address

first, the random number generator is used to generate a "private key". The subsequent public key and address will be generated by the private key, so the importance of the private key can be summarized in one sentence: & quot; Who has the private key, who has the right to use the wallet& quot;

"private key" is encrypted by elliptic curve algorithm (secp256k1) to generate & #; Public key;. This is an asymmetric one-way encryption algorithm. Knowing the private key can calculate the public key, but knowing the public key can't reverse calculate the private key

< / UL > < UL >

"public key" generates "public key hash"

through one-way hash algorithm (sha256, ripemd160), and connects a byte of address version number to the "public key hash" header (for the pubkey address of bitcoin network, The first four bytes of the result are used as the check value of "public key hash" and connected at the end of it

encode the previous result with base58 (customized version of bitcoin) to get the "wallet address"
