Privacy-focused crypto project ecosystem scan—this track has quite a few players. On the network layer, NYM provides privacy infrastructure, while HOPR focuses on private messaging communication. On the smart contract layer, there are two routes—XELIS and ABEL—one emphasizing privacy-oriented L1 application scenarios, and the other based on lattice cryptography technology. Looking further up, DUSK is an interesting player, combining features of regulated securities and privacy chains. But what’s relatively innovative is GHOST’s full-stack privacy layer solution built on Solana, attempting to add privacy capabilities to the existing ecosystem. The overall development approach for this sector is to cover everything from infrastructure to application layer.
