Threshold distributed signature algorithm
The cross-chain solution provided by Ordigate utilizes a threshold distributed signature algorithm based on multi-party computation (MPC). This algorithm allows for the secure generation of private keys on independently operated nodes, resulting in the creation of a corresponding public key through distributed computation. Notably, this approach offers several advantages:
Enhanced Security: The use of MPC ensures that private keys remain inaccessible and undisclosed throughout the entire process. No complete private keys are ever revealed, providing a higher level of security compared to techniques like secret sharing.
Privacy Preservation: During the distributed computation, nodes do not exchange the private keys they hold. This ensures that private keys are not passed between nodes, maintaining the privacy and integrity of the keys.
Protection against Key Derivation: The MPC mechanism ensures that the intermediate results generated during distributed computation cannot be exploited to derive the corresponding private keys. This protects against unauthorized access or misuse of the keys.
By applying this algorithm to the cross-chain interconnection of digital assets, Ordigate enables a decentralized approach to securely and effectively handle digital assets. This solution offers increased trust and reliability in managing assets across different chains while maintaining the privacy and security of the underlying private keys.
