Since its inception as a Hyperledger project almost two years ago, Hyperledger Cactus has come a long way. Today, the maintainers are excited to announce a version 1 release that supports many exciting integration applications and moves us in the direction of our “dream” modular architecture.
For creating a new token economy beyond financial and non-financial areas, blockchain interoperability has an essential role in interacting with multiple blockchains in various industries. But it is challenging to develop codes integrating with multiple blockchains because the SDKs provided by each blockchain for posting transactions or getting block data are entirely different. So, this community published a blockchain interoperability tool called “Hyperledger Cactus” to help engineers integrate multiple blockchains easily.
Hyperledger Cactus is a pluggable enterprise-grade framework for transacting multiple blockchains. This project aims to provide a decentralized, adaptable and secure integration between blockchains and various platforms. Cactus codes are composed of three types of parts. “Cactus Servers” provide abstracted APIs that can be uniformly called independent of each blockchain SDK’s format, and APIs that can use each blockchain SDK wrapped with the typescript-axios API format using Cactus API Server. “Business Logic Plugins” coordinate cross-blockchain business logic applications. “Ledger Connectors” facilitate connections to various blockchains, including all the blockchains of Graduated Hyperledger projects.
The Hyperledger Cactus v1 release includes the following modules:
As part of the continual effort to mitigate risks, the current 1.0.0 release is undergoing a a third-party security audit at the time of this writing.The process will take about 6 to 8 weeks to complete, but we are planning to keep the 1.0.0 API stability in place as dictated by the semantic versioning rules.
It’s effortless to try out Hyperledger Cactus today. We provide instructions for running a sample implementation of the Business Logic Plugins (service applications in Hyperledger Cactus architecture) that takes advantage of various blockchain platform features so you can evaluate Hyperledger Cactus on your PC.
It is even possible to set up a container with a supply chain example using a single command-line command! Here is a link to this example. We encourage you to see for yourself how easy it can be to get started with blockchain integration using Hyperledger Cactus.
Our long-term architectural goals for Hyperledger Cactus are to offer a flexible, modular system that allows users to configure blockchain integration systems to fit their needs exactly. We want users to reuse code as much as possible while still avoiding code bloat and duplication in the features. In future releases, we will actively cooperate with other Interoperability infrastructures besides Cactus, and we hope to provide more user-friendly tools by incorporating more features.

We would love to welcome you into the Hyperledger Cactus community. Unlike our project namesake, we are not prickly! Whether you want to contribute or are just interested in using Cactus, we would love to connect.
It’s easy to get in touch with us! The simplest way is to reach out on the Hyperledger Cactus Discord channel. (New to Discord? Go here for more and to get signed up.) We have pair programming sessions set up for new contributors and users almost daily (please check the Hyperledger calendar), so we would be more than happy to help if you would like to contribute or want help getting up and running. We look forward to hearing from you!
