Definition
Bitcoin’s protocol targets a 10-minute average block time through the difficulty adjustment mechanism. However, individual block intervals follow a Poisson distribution, meaning any single block might take anywhere from seconds to over an hour to find.
The 10-minute target is a tradeoff between fast confirmations and network stability. Shorter block times would increase orphan block rates and reduce security. The difficulty adjustment ensures this average holds regardless of total network hashrate.
In Simple Terms
The average time between blocks, targeted at 10 minutes. Individual blocks vary randomly around this average.
Block Time is a term used in Bitcoin mining related to network & protocol.
Also known as: Block interval, Average block time.

Understanding block time is important for Bitcoin miners because it directly impacts mining operations, hardware selection, or profitability calculations. Whether you are a home miner running a Bitaxe or operating a larger ASIC setup, this concept helps inform better mining decisions.
