Key Insights

• The Bitcoin hashrate has increased by 56% over the last year, currently averaging about 787 EH/s.
• If growth continues at a modest rate of 20%, the hashrate could reach 1 zettahash by 2027.
• The network has recorded seven consecutive positive difficulty adjustments since October, a period not seen since China's mining ban in 2021.

Bitcoin's hashrate, which indicates the computational power required for mining, is projected to hit 1 zettahash per second ahead of the upcoming halving event in 3.5 years. This will put pressure on miners to secure cheaper power and improve their operational efficiencies. The average rate could reach this milestone at a growth rate of just 20% annually, while it has already risen by an average of 65% since 2020 and stands at roughly 787 EH/s now, per insights from Glassnode. Moreover, higher hashrates imply increased energy costs, prompting miners to optimize their operations for profitability. This milestone becomes ever more critical as the bitcoin ecosystem pushes for new ways to adapt, especially after April's halving when block rewards were cut by 50%, leading some miners to pivot operations to areas such as AI computing.

Current Trends in Hashrate and Mining Difficulty

The rise in hashrate has coincided with increased mining difficulty, with the blockchain registering a notable count of seven consecutive positive difficulty adjustments currently at 109.78 trillion (T). Unlike the previous decline that followed the mining ban in China, the current hashrate and difficulty are increasing together, indicating a more robust mining environment. Miners will need to innovate further as they approach a time when achieving 1 ZH/s might require greater adaptability to sustain operations.
