What is the problem we're actually solving here? 1. Chain specific privacy protocols are only as private as the total amount of transfers going through them within that chain. That means that if you are the only user transferring that day, you'll need to stay in the protocol for an additional day before withdrawing. 24h transfer times vs immediate with Union. 2. Privacy protocols only support majors. You can privately transfer $ETH on Ethereum, but on Sei this will be hard/impossible, once again because the anonymity set is too small. Because our protocol combines anonymity sets, all $ETH transfers on Ethereum count for Sei as well. 3. Privacy within a chain is fine, but if you need to reveal because you are bridging to another chain, you still show your hand. This allows you to permanently stay private.
