I’m Zhiyong, a researcher and engineer working at the intersection of applied cryptography, blockchain systems, and AI.

This blog is where I publish detailed notes on topics I’m actively working on or exploring — think of it as my public knowledge base. The goal is to write the posts I wish had existed when I was learning something new.

What I write about

  • Applied Cryptography — zero-knowledge proofs, multi-party computation, threshold signatures, and how cryptographic primitives are actually used in real systems
  • Blockchain — protocol internals, smart contract security, consensus mechanisms, DeFi architecture
  • AI Tools — practical usage, workflows, and honest assessments of what works

Get in touch

The best way to reach me is by email. You can also find me on X and GitHub.

If something I wrote was useful, unclear, or just plain wrong — I’d love to hear from you.
