Lagrange: A Privacy-Preserving "Blockchain Calculator"🔐
Recently, I helped a friend with on-chain auditing, and the data was sensitive, so we didn’t dare to put it directly on-chain. Using Lagrange, I discovered it acts like a calculator with an encrypted filter; after calculating, the result goes on-chain, allowing others to verify correctness without seeing the private data✨
It’s a “super calculator that keeps secrets”:
When calculating sensitive data (like corporate revenue or credit scores), the inputs are “masked” throughout the process, with only the results being desensitized and placed on-chain📊
After collaborating with EigenLayer, the computing power soared, reducing the time to process 100 transactions from 1 hour to 10 minutes⚡
Three core capabilities:
Cross-chain accounting without data leaks: It reads data from multiple chains simultaneously, only outputting results without exposing the details of each chain💳
Adding a “trust lock” for AI inference: Model parameters and user data are encrypted, and the output “risk score” is verifiable🤖
Decentralized anti-cheating: Nodes stake LA to take orders; if they compute incorrectly and leak data, they lose coins, providing a strong sense of security🔒
Role of LA tokens:
Staking LA unlocks advanced features, improves computation priority, and greatly reduces queue time⏩
When nodes validate results, they earn LA; neighbors can take orders using their computers, earning enough monthly to buy a new hard drive🖥
Voting to change rules, LA represents voice; it once helped vote on a key proposal for the “AI Acceleration Package”📜
Summary: It makes blockchain computation “fast, secure, and mutually recognizable,” allowing privacy to be self-determined🚀
