Privacy and compliance—these two seemingly opposing concepts have long been difficult to reconcile in the crypto world. But recently, a new approach has gained attention—some teams have found a breakthrough using zero-knowledge proof technology. This EU MiCA-certified Layer1 public chain employs the PLONK scheme to achieve an interesting design: on the privacy side, the Citadel protocol supports anonymous KYC verification, and confidential smart contracts can hide sensitive transaction data; on the compliance side, regulators can still perform seamless audits and traceability. In simple terms, it can protect user privacy while not adding trouble for regulators.

The ecosystem data looks promising. Currently, over €196 million worth of securities assets are circulating on-chain, and a partnership with a leading exchange has even connected key links in traditional asset tokenization. Ecosystem tokens are actively involved in staking consensus, transaction fee distribution, and on-chain governance, becoming an important pillar in the RWA (Real-World Asset) track.

From institutional asset custody to privacy transactions for retail investors, such solutions are redefining what compliant finance looks like in Web3. Every value transfer can be both secure and free, which is a substantial progress for the entire ecosystem.
