What does the incentive mechanism in bitcoin mean
It's about 37 yuan
let me first introce the reward mechanism of bitcoin system
bitcoin can basically dig out a block every 10 minutes through system settings. The reward for each block is given to the miners who dig out the block. The miner who digs out the block is called the block miner. The block miner will record the legal transactions in the bitcoin network to the blockchain, so that the miner can receive the service charge for bookkeeping
there are two parts in the reward for the block Miner: one part is the reward given by the system, which is called coinbase reward (also known as system issuance reward), the other part is the reward for bookkeeping, which is called miner's fee. The coinbase reward started with 50 bitcoins. For every integral multiple of 210000 blocks, the coinbase reward will be halved. This is what we often hear about bitcoin mining reward halved in four years
at the present stage, the reward of coinbase is 12.5 bitcoins. At the present stage, the average transaction miner fee received by miners for digging out a block is about 0.1 bitcoin (not fixed), that is to say, the average reward received by miners for digging out a block is about 12.6 bitcoin
about 99% of miners' rewards come from the system's coinbase rewards. According to the bitcoin system, one block can be g out every 10 minutes on average. The number of new blocks that can be g out in one day is 144 (60 * 24 / 10 = 144). At present, the number of bitcoins that can be g out every day is 1800btc (144 * 12.5btc = 1800btc). With the miner's fee of about 0.1btc per block, the total reward for all miners in one day is about 1814.4btc
Bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it
mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash
and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on
extended data:
mining risk:
1, currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
2, system risk
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners
bitcoin system is composed of users (users control the wallet through the key), transactions (transactions will be broadcast to the whole bitcoin network) and miners (a blockchain is generated by competitive computing to reach a consensus at each node, and the blockchain is a distributed public authoritative account book, including all transactions in the bitcoin network)
mining is a process of increasing bitcoin money supply. Mining also protects the security of the bitcoin system, prevents fraulent transactions, and avoids "double payment", which means spending the same bitcoin multiple times. Miners offer algorithms for bitcoin networks in exchange for the opportunity to get bitcoin rewards. The miners verify each new transaction and record it in the general ledger. Every 10 minutes, a new block will be "mined", and each block contains all the transactions from the generation of the previous block to the present, which are added to the blockchain in turn. We call the transactions included in the block and added to the blockchain "confirmed" transactions. After the transaction is "confirmed", the new owner can spend the bitcoin he gets in the transaction
there are two types of rewards for miners in the process of Mining: the new currency reward for creating a new block, and the transaction fee for the transaction contained in the block. In order to get these rewards, miners compete to complete a mathematical problem based on encrypted hash algorithm, that is, to use bitcoin mining machine to calculate the hash algorithm. This requires strong computing power, how much the calculation process is, and whether the calculation results are good or bad. As the proof of miners' calculation workload, it is called "workload proof". The competition mechanism of the algorithm and the mechanism that the winner has the right to record transactions on the blockchain ensure the security of bitcoin
miners also get transaction fees. Each transaction may contain a transaction fee, which is the difference between the input and output of each transaction. A miner who successfully "digs" a new block in the process of mining can get all the transaction "tips" contained in the block. With the decrease of mining reward and the increase of the number of transactions in each block, the proportion of transaction fee in miners' income will graally increase. After 2140, all miners' earnings will be made up of transaction fees
mining is a process of decentralizing settlement, in which each settlement verifies and settles the processed transaction. Mining protects the security of bitcoin system, and achieves the consensus of the whole bitcoin network without a central organization. The invention of mining makes bitcoin very special. This decentralized security mechanism is the basis of point-to-point e-money. The reward and transaction fee for casting new coins are a kind of incentive mechanism, which can regulate miners' behavior and network security, and at the same time complete the currency issuance of bitcoin.
by the way, what game do you play?
if you hold a piece of gold in your hand, no one will give you a bonus. If the gold market price rises, it means you have a bonus
similarly, bitcoin is the same.
for example, you need to pay Niuniu 5 bitcoins, but there are 1 / 2 / 2 bitcoins in each of your a / B / C addresses, and the balance of each address is not enough to pay for 5 bitcoins
at this time, you can initiate a transfer and transfer 5 bitcoins from a / B / C to Niuniu. Take chestnuts. If you have five bitcoin addresses, you only need to transfer one to Niuniu. You need to tell the miner when transferring money: I have five bitcoins, one of which will be transferred to Niuniu, and the other four will be transferred back to myself (can be the original address or create a new address)
don't forget to say, otherwise the remaining four bitcoins will be used as handling charges for miners. This is the change mechanism of bitcoin.
a mining machine is a combination of computer hardware and computer program software that runs a specific algorithm based on bitcoin security mechanism!
