On December 15, Bitcoin's hash rate was recorded at 876.4 EH/s, down from about 930.06 EH/s on December 14 and from roughly 1.27 ZH/s a week earlier, reflecting a sharp pullback in network computing power. The decline has been linked to enforcement actions against mining operations in China's Xinjiang region, where an estimated 400,000 ASIC machines producing around 80‑100 EH/s were reportedly switched off. During the same period, Bitcoin traded near $89,930 after losing the $90,000 support level, with the price slipping about 0.1% in 24 hours and more than 2% over the week.

He proposed on-chain timestamps for content and engagement, delayed publication of algorithm code, and the use of layered cryptography, including MPC, FHE, and TEE, for applications such as voting. Buterin's ideas emerge as zero-knowledge rollups secure billions of dollars in value and are increasingly adopted by major financial institutions and stablecoin transactions.

On 15 December 2025, analysts highlighted that strong inflows into XRP-linked exchange-traded products have not lifted spot prices, as most buying occurs OTC rather than on centralized exchanges.
