Top 3 Milestones in ZK-Privacy History

The most significant technological breakthroughs that transformed Ethereum from a transparent ledger to a privacy-capable environment.

The top 3

  1. The Introduction of zk-SNARKs: First implemented by Zcash, these 'Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge' laid the groundwork for modern Ethereum privacy.
  2. The Emergence of Tornado Cash: While controversial, this non-custodial tool pioneered the use of zk-SNARKs to break on-chain linkability between sender and receiver addresses.
  3. Scaling via ZK-Rollups (2020-Present): The shift toward ZK-Rollups has allowed privacy to move from simple coin mixing to fully programmable, private decentralized applications.
