Global FHE Key

The protocol has a global FHE key component, which is used to encrypt and decrypt the confidential data. This encryption method operates on an asymmetric key framework, where clients utilize the public key for encrypting data, and only validators possess the corresponding private key for decryption. It is noteworthy that no single validator holds the entire key; instead, decryption necessitates a threshold signature mechanism based on Multi-Party Computation (MPC). This ensures a robust and distributed approach to confidentiality and security.
