From previous discussion we have got some points about the decentralization of the blockchain system to record and execute the transaction in the network. But here another question arrives: who will maintain the server and control & verify the transaction. There should be some parties in a decentralized manner obviously to control the server and maintain all the activities. And those who are responsible for maintaining the server from different parts of the world should be benefited from it. So how they will be benefited. To solve the core problems this question has to be answered. Let's get an idea about this part called miners today.

Miners verify transactions to confirm they are real. Miners solve puzzles using powerful computers and electricity. Verified transactions are added to the blockchain forever. Mining also creates new crypto for the miners. Bitcoin miners get rewarded with new Bitcoin coins. Mining is expensive and uses a lot of power.

Bitcoin has a maximum supply of 21 million. This limit helps prevent inflation and loss of value. Cryptos like Bitcoin are secure because of cryptographic technology. Cryptography protects transactions from being changed or faked. Other Crypto have different mechanisms. Mining should not always be like using electricity and solving mathematical problems.

Depending upon the nature of blockchain it can be of different form so that then electricity can be saved also as this is a concern for nature as well. People use cryptos to buy things online. Some use it to send money internationally fast. Many people invest in cryptos for future profit. Crypto prices can change very quickly every day. Not all cryptos are created by mining work. Some are created in advance and sold later. Others are created by staking coins in wallets. Staking earns rewards for supporting the crypto network. Due to issues of nature, this kind of blockchains are very popular and mostly visited in recent times.
