Purpose of mining Usually, one thinks of the purpose of mining in the blockchain to get bitcoin or other cryptocurrencies. While this is true, it is not the main purpose of mining. In fact, the main purpose of mining is to ensure the permanence and security of decentralized networks. The network includes nodes that store distributed ledgers in the form of a blockchain. Miners maintain the integrity of the blockchain by verifying transactions within it. Because of the incentive system, miners (nodes) will stay in the network and help prevent network outages. Consider this: If there were no rewards, no one would want to connect to the network, and blockchain would no longer exist.
How does the mine work? Mining begins when miners try to verify new transactions and record them on the blockchain. In the process, miners will compete to solve mathematical puzzles based on cryptographic hashing algorithms. The solution found is called proof of work, or Pow. When a block is solved, all transactions contained in the candidate block are considered valid and the new block is confirmed. This new block will be added to the blockchain. For Bitcoin, it takes about 10 minutes to confirm a new block, but for other cryptocurrencies, it's much faster. So if you send or receive Bitcoin, it takes about 10 minutes to confirm the transaction. Miners are rewarded for solving complex mathematical problems. There are two types of rewards: new bitcoins and transaction fees. The number of bitcoins created drops every four years, or · every 210,000 blocks, to be exact. Today, each newly created block generates 6.25 Bitcoins. That number will continue to decline until no more bitcoins are issued. This will happen around 2140, when 21 million bitcoins will be created. After that date, no more Bitcoins will be issued. However, miners can still be rewarded in the form of transaction fees. The winning miner can collect all transaction fees in the block. With each block created by the ratio
With fewer coins, miners will be charged more for transactions. After 2140, the winning miner will be rewarded with a transaction fee
