Ioan Alin Tomescu Nicolescu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

Two-Round Byzantine Fault Tolerant (BFT) State Machine Replication (SMR) Protocol with Linear Authenticator Complexity and Optimistic Responsiveness

Publication number: 20240028612

Abstract: The present disclosure is directed to a leader-based partially synchronous BFT SMR protocol that improves upon existing protocols by exhibiting two rounds of communication latency, linear authenticator complexity, and optimistic responsiveness. This is achieved through the novel use of an aggregate signature scheme as part of the protocol's view-change procedure.

Type: Application
