Bitcoin Network Stats

The Bitcoin network hashrate represents the total combined computational power of all miners worldwide. It acts as the primary measure of the network's security—the higher the hashrate, the more secure the network is against attacks.

Hashrate naturally fluctuates as miners upgrade equipment, electricity prices change, or Bitcoin's price moves. A rising hashrate typically indicates a healthy, growing mining ecosystem and strong conviction from miners.

• 1 Target Block Time: Bitcoin is designed to find a new block exactly every 10 minutes, regardless of how much hashrate is on the network.
• 2 Epochs: Every 2,016 blocks (roughly every two weeks) represents a mining "Epoch".
• 3 Difficulty Adjustment: At the end of each Epoch, the network automatically adjusts the "difficulty" of finding a block. If blocks were found faster than 10 minutes, difficulty goes up. If slower, it goes down.

Block height refers to the total number of blocks that have been successfully mined and added to the Bitcoin blockchain since the very first block, known as the genesis block (Block 0).

Because blocks are mined at a targeted interval of 10 minutes, block height is often used as a reliable indicator of time in the Bitcoin protocol. For instance, specific upgrades, halving events (which occur every 210,000 blocks), and smart contract locktimes are scheduled according to block height rather than calendar dates.

The Estimated Next Difficulty Change projects the percentage adjustment that will occur at the end of the current epoch. If blocks are being solved faster than the 10-minute target (due to an influx of network hashrate), the estimate will show a positive percentage increase to make mining harder. If blocks are being solved slower, it will show a negative percentage decrease to make mining easier.

This dynamic estimation updates with every new block found during the 2,016-block epoch, gradually becoming more accurate as the epoch progress approaches 100%.
