A recent dip in Bitcoin's hashrate has sparked discussion about network security. According to reports, a major US mining pool, Foundry, experienced a significant shift in power. The hashrate drop, visible on charts like BitInfoCharts, is estimated based on blocks found over time and can be influenced by factors like weather. Winter storms and grid stress can cause miners to curtail operations, impacting hashrate. While a one-day drop is a clue, longer averages provide a more accurate picture. Block times and mempool data can also indicate changes in mining capacity.
