COMPUTER SYSTEMS AND METHODS FOR SECURE AND SCALABLE DIGITAL ASSET CUSTODIAN

Abstract: embodiments described herein relate to computer systems and methods for digital asset custodian that seamlessly integrates off-chain multi-party computation (mpc) signing with on-chain party identity authentication. the system comprises a service provider node, multiple computation nodes equipped with robust secure hardware, and a blockchain accessible to all participating nodes. the nodes deliver a threshold signing service with utmost security—ensuring that no single node can recover the private key, while simultaneously recording and mutually authenticating each node's identity on-chain. the system boasts intrinsic support for hierarchical address creation and signing, facilitated by an enhanced protocol. its scalability, particularly in the quantity of computation nodes, is complemented by efficient communication tailored to the demands of the mpc protocol.
