The calculation difficulty of the Bitcoin network drops by 11.16%!

The Bitcoin network has just suffered a major technical shock. Its mining difficulty fell by 11.16%, the largest drop recorded since mining was banned in China in 2021. This sudden decline, revealing structural tensions, revives concerns about the robustness of the system and the growing pressure on mining companies. While the difficulty is supposed to ensure the stability of the protocol, its current plummet acts as a silent warning about the true state of the network and the resilience of its infrastructure.

A brutal dive into the mechanics of the network

Bitcoin mining difficulty saw a dramatic drop of 11.16%, falling from 141.61 T to 125.86 T at the height of block 935 429.

This adjustment marks the largest drop in a single adjustment since China's mining ban, with comparable declines recorded between 12.6% and 27.9% in 2021 episodes. The average time taken to mine a block recently stood at 9.47 minutes, compared to a theoretical target of 10 minutes, indicating increasing tension in the network ahead of this adjustment.

This algorithmic mechanism aims to maintain the stability of the network regardless of hashrate fluctuations. When the difficulty drops, it means that the available computing power has decreased significantly. Several key elements confirm this phenomenon:

• The adjustment block: 935,429, with the next adjustment expected around February 20;
• The measured variation: -11.16%, compared to +1.65% in the previous adjustment;
• CoinWarz data: difficulty recalibrated to 125.86 T, down sharply from the January peak;
• The next forecast: +5.63%, if the hash rate stabilizes.

A drop in difficulty of this magnitude has not occurred since the sanctions imposed on Chinese mining specialists almost five years ago.

This drop in difficulty marks an important technical inflection point, signaling a sudden adaptation of the protocol to mining conditions made more complex by a tangible reduction in the power committed to the network.

Turbulence in the mining sector

This decline in difficulty cannot be explained solely by an algorithmic adjustment. Several economic events have put a strain on the infrastructure of mining companies in recent weeks.

In January, winter storm Fern swept across the United Statescausing massive power outages across 34 states. Mining facilities have been forced to drastically reduce their energy consumption. Foundry USA briefly lost nearly 60% of its hashing power, dropping from nearly 400 EH/s to around 198 EH/s, illustrating the tangible impact of extreme weather on network security.

Added to these disruptions is a more worrying dynamic for the industry. According to the data collected, the network's total hash rate has fallen to its lowest level in four months, as mining companies' margins shrink and some operators redirect their resources to other digital activities such as data centers for AI.

The bear market, the drop in the price of BTC, which went from more than $125,000 to around $60,000 before a rebound, and a sharply compressed hash price forced the least efficient players to shut down machines that had become unprofitable.
