Description：Concordium is a proof-of-stake blockchain with built-in identifiers to meet regulatory requirements while providing a user-friendly platform that can handle smart contracts. Concordium leverages Zero Knowledge Proof (ZKP) to allow parties to verify information without trading on-chain or storing information other than hash functions, so users can trust that their privacy business will not become someone else’s business. Concordium’s unique ID disclosure mechanism allows regulators to revoke privacy to identify suspicious bad actors and illegal transactions.
