Hyperledger Cacti

More About hyperledger.org

Hyperledger Cacti is an open source blockchain interoperability framework (blockchain interoperability) hosted by the Hyperledger Foundation and LF Decentralized Trust, designed to support secure, pluggable integration between distinct distributed ledger technologies operated by enterprises and institutions. It focuses on enabling data exchange, asset movement, and coordinated workflows across multiple permissioned and public blockchain networks without forcing consolidation on a single platform.

The framework provides an extensible, component-based architecture (integration framework) in which different blockchain networks are integrated through connectors and plugins. These connectors interact with underlying ledgers via their native protocols and SDKs, while Cacti coordinates cross-chain operations at a higher abstraction layer. Typical use cases include atomic or dependable asset transfers between ledgers, synchronized state across separate business networks, and cross-chain workflows that link existing systems of record to one or more DLT platforms.

Cacti focuses on interoperability capabilities (blockchain middleware) such as cross-chain transaction routing, coordination logic, and standardized interfaces for initiating and monitoring operations that span multiple networks. It is structured so that organizations can add or update ledger-specific connectors as separate modules, which aligns with environments where different business units, partners, or consortia rely on distinct blockchain stacks. The project emphasizes a plugin model so that multiple DLT technologies can be supported under one interoperability framework.

Enterprises use Cacti in scenarios where they operate or interact with more than one blockchain network (enterprise integration), for example across supply chain consortia, financial networks, or multi-jurisdictional deployments. In such architectures, Cacti can sit between application layers and individual ledgers, providing APIs and configuration mechanisms to define which networks participate in cross-chain flows and how assets or data should move between them. This position allows organizations to retain existing ledger investments while enabling cross-network workflows.

From an enterprise architecture perspective, Hyperledger Cacti aligns with categories such as integration middleware, cross-domain transaction orchestration, and blockchain interoperability tooling. It is part of the broader Hyperledger ecosystem (enterprise blockchain) and is governed under the LF Decentralized Trust structure, which maintains processes for open development, technical direction, and community collaboration. For directory and taxonomy use, the project fits under open source distributed ledger interoperability frameworks, providing pluggable connectors, APIs, and orchestration logic for multi-ledger environments operated by regulated and large-scale organizations.
