How is Bitcoin produced

The generation mechanism of Bitcoin is based on the process of "mining". Miners use powerful computers to solve complex mathematical problems to verify transactions and package them into blocks to form a blockchain. This process relies on the Proof of Work mechanism (PoW), which is a block reward by competing to find random numbers that meet certain conditions. The reward is initially 50 bitcoins and follows a halving mechanism, which is halved every four years, while miners can also receive transaction fees. The total amount of Bitcoin is capped at 21 million, and the network is decentralized and not controlled by any single organization. These characteristics constitute the core value of Bitcoin.

Bitcoin is generated through the "mining" process, and the following is its generation mechanism:

1. Mining

• Definition: Mining is a process of using computers to solve complex mathematical problems. After successful resolution, the miner will receive a Bitcoin reward.

• Process: The miner verifies the transaction and packages it into a block, each block contains a set of transactions and a hash value pointing to the previous block, forming a blockchain.

2. Proof of Work (PoW)

• Mechanism: The miner needs to find a random number (nonce) that meets certain conditions, so that the block hash value is less than the target value.

• Difficulty adjustment: The network adjusts the difficulty every 2016 blocks (about two weeks) to ensure that the block generation time remains at about 10 minutes.

3. Block Rewards

• Initial Reward: When Bitcoin was born in 2009, 50 Bitcoins were rewarded for each block.

• Half mechanism: every 210,000 blocks (about 4 years), the reward is halved. As of 2023, the reward is 6.25 bitcoins.

4. Transaction fees

• Additional income: In addition to block rewards, miners also receive processing fees paid by transaction initiators.

5. The upper limit of total quantity

• Upper limit: The total amount of Bitcoin is 21 million, and it is expected that all of them will be dug around 2140.

6. Decentralization

• Features: The Bitcoin network is decentralized and is not controlled by any single entity and maintained by all participants.

Summarize

Bitcoin is generated through mining, and miners receive rewards by solving mathematical problems, with a limited total amount and decentralized.
