ZAMA: BUILDING HTTPS FOR BLOCKCHAINS

Summary from the TLDR Crypto newsletter

Crypto's biggest barrier to mainstream adoption is that everything onchain is public by default - wallet balances, transaction history, DeFi positions, and payroll are all visible to anyone. While early crypto users valued this transparency, it's wildly unsafe for normal people, businesses, banks, and governments. Zama is building what it calls “HTTPS for blockchains” using Fully Homomorphic Encryption (FHE) to enable confidential smart contracts, aiming to upgrade crypto from “everything is public” to “encrypted by default” - potentially the most important infrastructure shift since smart contracts.
