Ethereum developer Leo Glisic has introduced "Privacy Guardians 2.0," a proposal aimed at maximizing privacy for on-chain payments. The project, now open-sourced, seeks to address privacy concerns associated with centralized payment systems by offering a decentralized alternative. The current version includes modules for private payments, insurance, honeypot design, exchange rate management, liquidity pools, and metadata processing. Glisic emphasized that the project is in its early stages, with opportunities for improvement in cryptographic security, incentive mechanisms, and capital efficiency. He has invited the community to contribute to the project's development. The whitepaper is available at glisic.xyz.
