How long does it take to mine one Bitcoin?

The cycle to generate one Bitcoin is about 10 minutes, including five stages: 1. Block creation; 2. Calculation of hashes; 3. Difficulty adjustment; 4. Verification of blocks; 5. Reward distribution.

The generation cycle of a Bitcoin

The generation of a Bitcoin requires the following stages:

1. Block Creation

• Miners collect unconfirmed Bitcoin transactions and package them into a block.
• A block contains transaction information, the hash value of the previous block, and a random number (called a nonce).

2. Calculate the hash

• The miner repeatedly adjusts the random number until it finds a hash value that meets certain conditions.
• A hash value is a unique identifier generated by a complex mathematical formula.

3. Difficulty Adjustment

• The difficulty of hash value calculation is adjusted regularly to maintain an average block generation of one every 10 minutes.
• The higher the difficulty, the more difficult it is to find a hash value that meets the conditions.

4. Verify the Block

• Once the miner finds a valid hash, the block is broadcast to the Bitcoin network.
• Other nodes in the network verify whether the block is valid, and if so, add it to the distributed ledger (blockchain).

5. Reward distribution

• The miner who discovers a valid block will receive 6.25 Bitcoins as a reward.
• The block reward is halved every four years, which is called "halving".

Timeframe

The time it takes to generate one Bitcoin depends on the network hash rate and block difficulty. Hash rate refers to the number of hashes calculated per second by a network node.

At current hash rates and difficulty levels, it takes an average of 10 minutes to generate a block. Therefore, the generation period of one Bitcoin is usually about 10 minutes. However, this time can vary depending on network conditions.
