On Wednesday, June 8, the Bitcoin network achieved a new milestone as its hashrate hit an all-time high of 292.02 EH/s, inching closer to the 300 EH/s (0.3 Zettahash) threshold. This record was set at block height 739,928, underscoring the relentless growth of the network's computational power.
Difficulty Adjustment Surprises with an Increase
Contrary to market expectations of a 0.51% decrease, Bitcoin's mining difficulty rose by 1.29% on the same day, reaching 30.28 trillion. The uptick reflects the sustained high hashrate, though current difficulty remains below the all-time high of 31.25 trillion recorded on May 10. The next difficulty retarget is scheduled around June 21 (approximately 1,600 blocks away), and preliminary estimates suggest another increase of 1.52%.
Growth Trajectory: 6.18% Gain in 37 Days
The previous hashrate ATH of 275.01 EH/s was set on May 2 at block 734,577. In just 37 days, the network's processing power surged by roughly 6.18%, propelled by aggressive deployment of next-generation mining rigs and the expansion of North American mining operations following China's crackdown in 2021. The rapid ramp-up has solidified Bitcoin's position as the most secure proof-of-work network.
Mining Pool Dominance: Foundry USA Takes the Lead
Over the past 72 hours, Bitcoin miners produced 475 blocks. Foundry USA led the pack with 52.42 EH/s, mining 109 blocks. Antpool came second with 35.11 EH/s (73 blocks), followed by F2pool with approximately 32 EH/s (67 blocks). Together, these three pools accounted for nearly 41% of the total network hashrate.
Significance of the 300 EH/s Threshold
Crossing 300 EH/s would mean performing 300 quintillion (3×10²⁰) hash calculations per second. Analysts view this as a key psychological milestone for Bitcoin security: higher hashrate makes 51% attacks economically prohibitive, further strengthening network immutability. However, the rapid hashrate growth also pressures smaller miners through rising difficulty and tighter margins.
Overall, the new ATH at 292.02 EH/s reaffirms miners' long-term confidence in Bitcoin. Whether the hashrate can push past 300 EH/s in the coming weeks will depend on factors such as mining rig deployment rates and electricity cost dynamics.
