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
POC consensus mechanism integrates the advantages of pow / POS / dpos, and achieves better coordination of decentralization, efficiency and consistency in different directions, which are difficult to unify in blockchain< br />
1. Decentralization: in the POC consensus mechanism, there is no rigid limit on the number of nodes. The number of nodes is dynamic, and anyone who meets the conditions can join the nodes. Here, each outgoing node is similar to the mine pool in the pow, and can join the consensus in the mine pool by holding interests. In the pow, the pool obtains the bookkeeping rights according to the computing power. In the POC, the chance of all the pools to obtain bookkeeping rights is random and equal, which makes the node distribution of the consensus mechanism of POC more decentralized< br /> < br />
2. Efficiency: the two key factors affecting the efficiency of blockchain network are the degree of wide distribution of nodes and the hardware network resources provided by nodes. In the coordination of these two parameters, POC consensus mechanism introces the credit coefficient mechanism, which directly affects the stability of the node. Therefore, each node and the principals participating in the node will make the most favorable choice for the network to ensure that the node can provide services efficiently and stably. In addition, they will join the node consensus by means of rights and interests, The number of nodes will float in a certain range, which can be adjusted by changing the incentive parameters. When the parameters are fixed, the market will adjust automatically. In these nodes, the dpos principle of random sorting out blocks is integrated, which ensures the security and efficiency of the network and provides higher TPS carrying capacity< br />
3. Consistency: in the POC consensus mechanism, all members can participate in the consensus, and the node can only charge a certain fee to the participants. All people have equal opportunities to participate in the consensus, and the incentive is determined by the equity and node credit coefficient. Nodes and all participants will reach a consensus in order to provide stable node services.
Yfi is the token of year.finance project, which is jokingly called "Uncle" by netizens. Year.finance is a decentralized financial platform. Recently, the word "decentralized finance" is also very popular in the coin circle, that is, defi
The goal ofyear.finance is very simple, it is an aggregation platform for the loan platform to service the profit output data of different procts, and it obtains the highest profit output in the contract transaction interaction by rebalancing the data
{rrrrrrr}
extended data:
1. The total number of yfi is small:
the total number of yfi issued is only 30000. At present, more than 50% of yfi tokens are locked in different liquidity mining pools. The number of yfi flowing (tradable) outside is less than 15000. The quantity is rare, and the price is high
2. Yfi token allocation:
generally, the token allocation of a project includes founder holding, team holding, private placement, public offering, working capital and other aspects, which together will basically exceed 50% of the total amount of tokens. When these shares are unlocked, it will cause certain selling pressure
3. Hot spot of defi + project Hype:
when yfi was born, it was in the hottest period of defi, and a series of operations of the project side attracted a lot of heat. To sum up, it can be seen that yfi is actually an ordinary defi project. The reason why the recent popularity is so high is that in addition to the large increase, it is the super high unit price of 220000 yuan. Although the unit price of yfi is high, its market value is not particularly prominent. The circulation market value is about 2-4 billion yuan, which is more than 200 billion yuan compared with that of bitcoin
I have seen your question. In which aspects can blockchain be applied? Below by the small series to answer for you
