Free Fortune Telling for Miners _ Mine Gold Fortune Telling

Who paid for the miners' fees in Ethereum?

Employees. On the public chain, anyone can read and write data. Reading data is free, but writing data into the public chain requires a certain fee, which helps to prevent junk content and protect its security by paying. Any node on the network (every connected device containing a copy of the account book is called a node) can participate in protecting the network in a way called mining. Because mining requires computing power and electricity, miners need to pay for their services, which is also the source of miners' expenses.

What is gas?

The difference between Ethereum and Bitcoin is that Ethereum introduces the concept of gas, and the purpose of gas is to limit the workload required to execute the transaction and pay for the execution. Gas is used to measure resources (including computing, storage, bandwidth, etc.). ) is consumed by your transaction (or contract code call). The transfer fee generated by the transaction will be awarded to the miners who package the block containing the transaction. The block was not produced by any miners. All miners will compete for the right to package the next block, and the winner can package the next block.

There is not necessarily a block in the transaction. After the transaction is broadcast, all nodes in the whole network will receive the transaction within a few seconds. Miners will give priority to packaging transactions with reasonable gas prices and high gas prices. If the user pays a very low mining fee (dead gas) during the transaction, the transaction may not be packaged by the mining company, resulting in the failure of the transaction. Transaction cost of etheric currency = gas quantity * gas price (gas unit price, denominated in etheric currency)

The gas fee is obtained by multiplying the gas limit and the gas price. The default value of gas limit is different in different periods and operations, but you can set the gas limit yourself when performing operations. It should be noted that the number of gas units required to complete a transaction depends on the complexity of the transaction. When a transaction is more complex, it must consume more computing resources, so it needs to spend more gasoline. The price of natural gas refers to the quantity of Gwei, which will affect the speed at which your transactions are packaged by miners and put on the blockchain. If the price of natural gas is set higher, it will give miners more incentive to package your transaction; On the contrary, if the gas price is set low, it will take a long time. If you are not in a hurry to complete a transaction, you can choose a lower gas price to save money. In each transaction, you can adjust the gas price and gas price according to your own needs.
