This series explores how modern encryption allows us to send secure data over public networks using surprisingly simple ideas—often explained through real-world analogies like mixing paint or using padlocked boxes.
本系列讲解现代加密如何通过出人意料的简单原理，让我们在公共网络中安全传输数据，并用现实生活中的类比（如混合颜料、上锁的盒子）帮助理解。
Explore infinities, the Axiom of Choice, and the Banach–Tarski Paradox in this journey through set theory. Discover how deep math ideas can be surprising, counterintuitive, and even a little paradoxical.
「一」之后是什么？本视频带你走进集合论的奇妙世界：有的无穷比另一些「更大」，选择公理颠覆直觉，从良序原理到著名的巴拿赫-塔斯基悖论，带你探索那些看似明显却又充满争议的数学真理。你的证明方式，也许正取决于你的选择。
Privacy must be Ethereum’s default, not an option. This roadmap advocates protocol-level integration of privacy, enabling secure, sovereign use without forcing users to prove innocence. It proposes selective disclosure and dissociation tools to balance privacy with compliance, aiming to make Ethereum both regulator-friendly and fundamentally privacy-preserving.
以隐私为默认的以太坊是实现用户主权的关键。该路线图主张将隐私深度集成至协议层，同时通过选择性披露和「去关联」机制，在保护用户隐私的同时应对监管挑战，推动以太坊迈向更安全、自主的未来。
This post explores code optimizations in post-quantum cryptography, highlighting lattice-based cryptography’s vectorization advantages via SIMD. These enable efficient polynomial and matrix operations, making it highly performant. In contrast, isogeny-based cryptography offers compact keys but limited vectorization potential. Lattices stand out for their versatility and speed.
本文探讨格基密码在后量子加密中的优化潜力，特别强调其在向量化（SIMD）方面的优势，可显著提升运算效率。相比之下，同源映射加密难以向量化，尽管拥有更小密钥。格基方法因结构规律性，在执行矩阵/多项式运算时更易并行处理。
