Abstract: Threshold distributed elliptic curve key generation and signature system and method are disclosed where nodes can generate their own key pairs without the participation of a trust center, each node can process its own key pair according to a secret sharing protocol, complete conversion of the (n, n) threshold to the (t, n) threshold, after determining t signature node, generates a (t, t) threshold private key according to a threshold logic, complete mapping of ptki to ptki?, and according to a signature logic, use ptki? to complete the communication and calculation in the signature protocol, store the relevant calculation results, and complete an overall signature.

Abstract: The present disclosure provides a method and system for decentralized digital asset storage and transfer. An exemplary system includes a platform including at least three dedicated and computationally independent computing nodes, and a first access gateway communicably coupled to the platform. The platform is configured to, upon receipt of a digital asset storage or transfer instruction via said first access gateway, perform a method including: performing, by each said node independently, a verification process in respect of said instruction to determine a verification result, and broadcasting said verification result thereof to the other nodes; determining a consensus between verification results determined by said nodes; and in the event of a consensus, each node processing said instruction, independently of said other nodes.
