Weakening US employment indicators are reshaping expectations for economic growth, interest rate trajectories and market liquidity. These shifts are introducing fresh macro headwinds for Bitcoin and the broader digital asset sector. Traders are recalibrating risk exposure amid mixed labor signals as the unemployment rate climbs to multi-year highs and monthly payroll additions moderate from post-pandemic peaks.

Major layer-1 blockchain networks are incorporating post-quantum cryptography into their technical roadmaps as a long-term security priority. The shift follows NIST's standardization of quantum-resistant algorithms between 2022 and 2024. Teams are addressing potential vulnerabilities in elliptic-curve signature schemes before quantum computers reach cryptanalytic capability.

Ethereum will activate its Fusaka upgrade on December 3, 2025, at slot 13,164,544. The upgrade introduces PeerDAS technology through EIP-7594, enabling validators to verify rollup data by sampling random cells rather than downloading complete datasets. The protocol changes target rollup scalability by reducing validator bandwidth requirements while creating pathways for an 8x increase in blob capacity without requiring data center infrastructure for home stakers.
