Key Points
- Bitcoin mining difficulty hits a record high of 86.4 trillion ahead of the halving event.
- Bitcoin's hash rate could drop by 20% after the halving, according to Galaxy's mining analysts.
Ahead of the anticipated halving event, the difficulty of mining Bitcoin has reached new heights.
The halving event, which is set to reduce miner rewards by 50%, is preceded by a surge in mining difficulty.
Bitcoin Mining Difficulty and Hash Rate
The mining difficulty, which hit a record 86.4 trillion, is an indication of how hard it is to mine a new block or solve mathematical puzzles under Bitcoin's proof-of-work (PoW) consensus mechanism.
The difficulty is adjusted every 2,016 blocks, or approximately every two weeks, as Bitcoin is programmed to self-adjust the difficulty level to maintain a target block time of 10 minutes.
The mining difficulty is directly related to the Bitcoin blockchain hash rate, a unit measuring miners' computational power to produce new Bitcoin.
With the increase in Bitcoin mining difficulty, the BTC hash rate has also seen a significant increase, surging from around 619 exahashes per second (EH/s) on March 28 to 696 EH/s on April 10.
Future Predictions
Some analysts predict that the BTC hash rate will likely drop after the upcoming Bitcoin halving in 2024.
According to analysts at Galaxy, as much as 20% of Bitcoin's current hash rate could go offline after the Bitcoin halving, as many miners will likely turn off their mining rigs due to lowered efficiency post-halving.
They further stated that more than 70% of the Bitcoin hash rate was churned out by eight ASIC miner models by the end of 2023.
