AI Technical Summary

Technical Problem

Existing blockchain transaction approval mechanisms are vulnerable to compromise due to multiparty collusion and database vulnerabilities, leading to unauthorized transactions and fraudulent approvals.

Method used

Implementing multi-party threshold transaction approval and key recovery techniques, where transactions are distributed across a set of nodes with weighted importance, requiring cumulative weight exceeding a threshold for approval, and cryptographic keys are sharded and reconstructed from node contributions.

Benefits of technology

Enhances transaction security by increasing the number of compromised parties needed for malicious transactions, minimizing fraudulent approvals, and eliminating database vulnerabilities through distributed key recovery.

Abstract

Certain aspects of the present disclosure provide techniques for securely processing transactions on a blockchain or other distributed computing system. An example method generally includes receiving a request to execute an action in the distributed computing system. Based on the request, a set of systems in the distributed computing system are identified to approve the request to execute the action. Generally, each system in the set of systems has a weight associated with the system. Approval is requested from systems in the set of systems for execution of the request to execute the action in the distributed computing system. The action is executed in the distributed computing system based on a cumulative weight of approving systems from the set of systems exceeding a threshold weight for approval.
