When a Bitcoin miner is working on the Bitcoin network, they are verifying and processing transactions. In order to do this, they need to solve a math problem.
The math problem is different for each transaction and is known as a cryptographic puzzle.
The cryptographic puzzles are designed so that they can only be solved by computers. They are also designed so that it takes a lot of time and energy to solve them.
This is why Bitcoin miners need to use powerful computers and why they need to be connected to the internet.
When a miner solves the cryptographic puzzle, they are rewarded with a certain amount of Bitcoin. The amount of Bitcoin that a miner gets per puzzle is known as the block reward.
The block reward is how new Bitcoin is created on the network.
The block reward started at 50 BTC per block when Bitcoin first launched. It halves every 210,000 blocks, which works out to about once every 4 years. The current block reward is 12.
5 BTC per block. This will continue until the total supply of 21 million BTC has been mined.
So what puzzles do Bitcoin miners solve? They solve cryptographic puzzles in order to verify and process transactions on the network. By doing so, they are rewarded with new Bitcoin.
