508 results about "Consensus" patented technology

A fundamental problem in distributed computing and multi-agent systems is to achieve overall system reliability in the presence of a number of faulty processes. This often requires processes to agree on some data value that is needed during computation. Examples of applications of consensus include whether to commit a transaction to a database, agreeing on the identity of a leader, state machine replication, and atomic broadcasts. The real world applications include clock synchronization, PageRank, opinion formation, smart power grids, state estimation, control of UAVs (and multiple robots/agents in general), load balancing, blockchain and others.

Adaptive Network Framework For Modular, Dynamic, and Decentralized Systems

A distributed indexing and resolution architecture is disclosed for decentralized systems requiring modular, trust-scoped mutation control and dynamic alias governance. The system comprises a plurality of index entries arranged in a parent-child hierarchy, each associated with a structured alias and governed by one or more anchor nodes. Anchors perform localized resolution, mutation validation, and restructuring operations under deterministic policy constraints, enabling semantic scope enforcement and entropy-sensitive adaptation without requiring global consensus or centralized control. The architecture supports scoped alias traversal, asynchronous mutation proposals, and elastic anchor registration based on system state metrics. The indexing substrate may be integrated into heterogeneous infrastructures, including systems comprising distributed software agents, semantic execution platforms, or pseudonymous identity frameworks. Anchors coordinate within defined trust domains to ensure lineage continuity, dynamic rekeying, and semantic integrity across independently governed segments of a decentralized namespace.

Asynchronous continuation mechanism for chained instructions in resilient decentralized systems

A method and system for executing chained instructions in a resilient, decentralized architecture are disclosed. The system enables complex workflows through an asynchronous continuation mechanism. An initial instruction, executed by a first entity in a leading validation cluster, can generate one or more continuation instructions directed to other entities. These continuations are executed immediately on a “fast track” path within the leading cluster, creating a high-speed, non-blocking sequence of cross-entity actions prior to network-wide consensus. The resulting ordered sequence is then proposed to follower clusters, which perform a consensus before executing a duplicate, verifiable instance of the entire instruction chain. This separation of optimistic, continuation-driven execution from deliberate, consensus-based finality facilitates a pipelined and parallel processing model. The architecture provides the foundation for resilient microservice applications requiring complex, low-latency, and asynchronous interactions across a scalable, decentralized system.
