Looking ahead to 2025, Bitcoin's technological evolution exhibits three core characteristics, which are also the key to understanding the following 10 major events:

Defense Forward: The defense roadmap against quantum threats has become clearer and more practical for the first time, extending security thinking from the "present" to the "post-quantum era."
Functional Layering: The high-density discussions on soft fork proposals and the "hot-swappable" evolution of the Lightning Network demonstrate that Bitcoin is achieving its architectural goal of "bottom-layer stability and top-layer flexibility" through layered protocols.
Infrastructure Decentralization: From mining protocols (Stratum v2) to node verification (Utreexo/SwiftSync), a large amount of engineering resources have been invested in reducing participation barriers and enhancing resistance to censorship, aiming to counteract the centralizing forces of the physical world.
