What is Bitcoin’s target average time for mining one new block?

Bitcoin’s target average time for mining one new block is 10 minutes.

This interval is maintained by Bitcoin’s difficulty-adjustment system. Mining difficulty changes approximately every 2,016 blocks, or about two weeks, so that the network’s overall computing power does not permanently make blocks arrive much faster or slower.

Ten minutes is a target average, not a guaranteed schedule. Individual blocks can be found only seconds apart, while other blocks may take considerably longer. The system uses proof-of-work: miners compete to find a valid hash, and the winning miner broadcasts the block to the network.

The target should not be confused with transaction confirmation time. A transaction can enter a block quickly, but users may wait for additional blocks before treating a payment as strongly confirmed. Bitcoin’s block-size and transaction-fee rules also affect how quickly transactions are included.
