ZCASH 2.0 & PROJECT TACHYON

Summary from the TLDR Crypto newsletter

Bitcoin's pseudonymity has failed to provide true privacy, while centralized structures like ETFs enable wealth seizure, and transparent balances expose users to physical attacks, creating demand for genuinely private money. Zcash uses zero-knowledge technology with end-to-end encryption to achieve real privacy, but current ZK systems face severe scalability limitations from state contention and wallets needing to download all transactions. Project Tachyon, led by ZK engineer Sean Bowe, aims to solve these scalability issues within 12 months, potentially creating the world's first private money at planetary scale.
