Aleph Zero is designed for use in enterprise, Web 3.0, and DeFi. It's a Proof-of-Stake public blockchain with private smart contracts created from the ground up. A unique aBFT consensus protocol and privacy framework based on ZKPs and sMPC is combined with the Substrate stack. A standout feature of Aleph Zero is its use of ZKPs and sMPC to secure and protect user data. These technologies have the potential to revolutionize internet privacy and give us control over our online personas. ZK-SNARKs provide a secure key exchange between users, while sMPC protects data through multiple computers that require consensus to access it. The result is a safer internet where sensitive data is only released with our consent.
