[Ethereum Researcher Releases 'Privacy Guardians 2.0' Proposal, Aiming to Achieve 'Maximum Attainable Privacy' for On-Chain Payments] Foresight News reports that Ethereum researcher Leo Glisic has published the 'Privacy Guardians 2.0' proposal on the research forum. The proposal includes replacing enterprise-controlled on-chain payments with the Privacy Guardians alternative, aiming to maintain as much privacy as possible for on-chain payments while still operating on-chain. The system features an interactive architecture comprising components such as private payment mechanisms, insurance mechanisms, honeypot and claim processes, exchange rate handling, liquidity pools, and metadata management.
