深入探讨隐私基础设施、零知识证明、密码学以及 Ethereum 和 L2 上机密交易的未来。
We open-sourced poseidon2-go, the first standalone, pure-Go implementation of Poseidon2 over BN254. Zero allocations, cross-verified against Noir and Solidity, and ready for your ZK backend.

Public blockchains have a privacy problem. Every transaction is permanent public data. Wallet addresses become identities. We built NIX Protocol to fix this - a lightweight set of smart contracts that adds privacy to any EVM chain without leaving the chains you already use.
Your browser has a GPU sitting there doing nothing while your wallet hashes on a single CPU thread. We wrote Poseidon2 as a WebGPU compute shader and got 7.8M hashes/sec on BabyBear and 323K on Grumpkin - up to 51x faster than JavaScript. Here are the numbers.
Exploring the transition from ECIES to post-quantum cryptography (Kyber, Dilithium) for future-proof on-chain privacy. A deep dive into lattice-based schemes and their blockchain applications.
A guide to ZK-SNARKs and ZK-STARKs, their trade-offs, and how they enable privacy-preserving computations on Ethereum.
How NixProtocol implements private transfers using UTXO notes, ECIES encryption, and zero-knowledge proofs in a privacy pool architecture.
A guide to implementing privacy features while maintaining regulatory compliance through selective disclosure and auditor access patterns.
Understanding how NixAddress encoding works, the UTXO note model for private payments, and how Grumpkin curve cryptography enables unlinkable transactions.
Exploring emerging trends in blockchain privacy: FHE, MPC, and next-generation ZK systems that will shape the future of confidential transactions.
