What is hole digging mechanism in ore pool

1.

Mine pool refers to:

as the computing level of the whole bitcoin network continues to rise exponentially, a single device or a small amount of computing power can not get the block reward provided by the bitcoin network on the bitcoin network

after the computing power of the whole network has been improved to a certain extent, the low probability of getting rewards has prompted some geeks on "bitcoin talk" to develop a method that can combine a small amount of computing power and operate jointly, and the website established in this way is called "mine pool"

extended data:

the existence of the mine pool reces the difficulty of bitcoin and other virtual digital currency mining, reces the mining threshold, and truly realizes the bitcoin mining concept that everyone can participate in

but its disadvantages are also very obvious, because computing power is connected to the mine pool. As a mine pool, it will have huge computing power resources. In the bitcoin world, computing power represents the bookkeeping right, and computing power is everything. If the computing power of a single mine pool reaches more than 50%, it will be easy to launch 51% attacks against virtual digital currencies such as bitcoin, The consequences are very terrible:

the mine pool can make the mine pool with 49% of the remaining computing power have no harvest, instantly quit the competition and go bankrupt. The mine pool's computing power exceeds 50%. If 51% attack is launched, it will easily occupy all the effective computing power of the whole network

2. The miner background is configured with three mining addresses, the first is the main mine pool address, and the second two are the standby mine pool address. In order to ensure the miner's mining income, the miner has set up an automatic detection mechanism of the standby mine pool, that is, the miner itself will continuously detect whether the standby mine pool is connected,
the miner continuously detects the availability of the standby mine pool, During this period, the main ore pool has been connected, so it will not affect your mining income.

3.

After the computing power of the whole network has been improved to a certain extent, the probability of getting rewards is too low, so that some geeks on "bitcoin talk" can develop a method that can combine a small amount of computing power and operate jointly, and use this method to build websites

in this mechanism, no matter how much computing power an indivial miner can use, as long as he participates in mining activities by joining the mine pool, no matter whether he has successfully mined effective data blocks, he can get a small amount of bitcoin reward through his contribution to the mine pool, that is to say, many people cooperate in mining, and the bitcoin reward is shared by many people according to their contribution

as of January 2019, the top five bitcoin pools in global computing power are btc.com, pool, antpool, flush pool, and f2pool. At present, about 70% of global computing power is in the hands of Chinese miners

extended data:

handling charge:

bitcoin miners will charge a small amount of fees for most transactions, the main purpose of which is to prevent people from sending a large number of boring small transactions and wasting network resources. At present, most of the handling charges for each transaction are & T 3647; 0.0001/kb (0.0001btc / KB). In fact, after 0.9.0, the default handling charge will be reced to & 3647; 0.00001/KB(0.00001 btc/KB)

because the amount of data occupied by most transactions is less than 1 kilobyte, generally speaking, the amount of data is less than 3647; 0.00001 (0.00001 BTC / KB) is enough. At the same time, in the future, when the bitcoin block rewards are less, the service charge will become the main source of miners' income, and the service charge of bitcoin will be related to the number of bytes occupied by the transaction

at present, the calculation standard of service charge in bitcoin system is not mandatory, so users can not give any service charge when the transaction is in progress

however, most miners usually give priority to the transaction with higher handling charges when building data blocks, so that they can get higher remuneration when mining is successful. Therefore, the transaction without any handling charges may take a long time to be processed and incorporated into the blockchain

in addition, e to the block capacity limit of 1MB and the recent increase in bitcoin transaction volume, the handling charges have increased significantly, and the waiting time for the transaction to be confirmed has also become much longer

4. The mine pool is a team mining server. Corresponding mine pool address and server address. Bitcoin generates a block every 10 minutes, and there will be tens of millions of people competing. In the end, only one person owns the block, and no one else receives anything
you may have to dig for 5 years to get a block. Team mining is that once anyone in the team gets a block, they will divide the currency in the block according to their performance, so that they can get bitcoin quickly.

5. As the computing level of the whole bitcoin network is rising exponentially, a single device or a small amount of computing power can not get the block reward provided by bitcoin network. After the computing power of the whole network has been improved to a certain extent, the low probability of getting rewards has prompted some geeks on "bitcoin talk" to develop a method that can combine a small amount of computing power and operate jointly. The website built in this way is called "mining pool"
because the probability of a single miner digging a block is very small, after all, it takes a lot of computing power to dig a block in 10 minutes. Even if there is such a large amount of computing power and the ability to dig, there are many competitors. So it becomes a game of 0 and 1. And the emergence of the mine pool is to break the 0 and 1 play. The computing power of a mine pool is a collection of many miners' computing power, which is far more likely than fighting alone. Every time you dig a block in the mine, you will be rewarded to the indivial according to the percentage of the calculation power of your mining machine in the total calculation power of the mine, and there will be no unfair situation.

6. According to the operation principle of the miner, the miner will continue to accept the tasks assigned by the mine pool, and return the calculation results to the mine pool. However, there is a delay in the communication between the mine machine and the mine pool network, and the invalid submission caused by the network delay is called the rejection rate.

7. The collective data bitcoin of mining machine can be made by computer. This is called mining machine. For example, if there are 1000 mining machines, they will eat 1000

8. Dpos: delegated proof of stake, certificate of rights and interests
PS: for details of this agreement, please refer to the latest blog "detailed explanation of [blockchain] dpos official consensus mechanism (BTS / EOS)"
the dpos mechanism of bitshares is called share authorization proof mechanism (also known as trustee mechanism) in Chinese, and its principle is to let everyone holding bitshares vote, Thus, 101 representatives are generated, which can be understood as 101 super nodes or ore pools, and the rights of these 101 super nodes are completely equal to each other. In a way, dpos is a bit like a parliamentary system or a people's Congress system. If the delegates can't perform their ties (when it's their turn, they can't generate blocks), they will be removed and the network will choose a new supernode to replace them. The emergence of dpos is mainly e to the proction of mining machines. A lot of computing power is on people who don't understand and care about bitcoin. Scalpers like concerts hoard a lot of tickets and don't care about the content of concerts at all.

9. Mining is the process of bookkeeping, miners are bookkeepers, and blockchain is the ledger. How to motivate miners to dig? The accounting power of bitcoin system is decentralized, that is, every miner has the right to account. Miners who successfully seize the bookkeeping right will be rewarded with bitcoin. Therefore, mining is the process of procing bitcoin. When Nakamoto first designed bitcoin, he stipulated that every
