Hyperledger Cacti
Hyperledger Weaver - merged into Cacti in 2022
Key principles that guide Weaver’s design are:
- Accommodate DLT heterogeneity without favoring a particular DLT design
- Allow networks to maintain their independence and collective sovereignty
- Minimize coupling during cross-network interactions
- Rely on common standards for cross-network protocol units
- Do not require a trusted intermediary or third-party ledger
- Do not require changes to existing DLT stacks
- Make no security and trust assumptions on Weaver components
- Treat privacy and least privilege as a first-class requirement
Weaver addresses three broad classes of use cases:
- Data transfer: ledger data (state) communication with proof
- Asset transfer: movement of an asset from one ledger to another
- Asset exchange: atomic exchange of asset ownership in different ledgers
The protocols to realize these use cases can be abstracted into a common stack of layers akin to the OSI model, from message formats at the bottom to governance rules at the top (see diagram below).

Blockchain Interoperability with Hyperledger Cacti Workshop
Time:
- Monday November 14, 2022 from 11am - 2pm ET
Registration:
Registration for the event is free. If you're interested in attending, we ask that you sign up now since space is limited.
Workshop description:
We present the "Blockchain Interoperability with Hyperledger Cacti" workshop, the first Hyperledger Foundation Community Workshop dedicated to blockchain interoperability. This is a three hour online course to introduce the core concepts and principles of blockchain interoperability. You will learn the foundations of interoperability, followed by an introduction to several Hyperledger projects on the field: Weaver, YUI, Firefly, and Cacti. We present in depth several Cacti's components, including its Plugin Architecture, API Server, Test Development & Execution (All-In-One Container Images), an Hello World of Cacti, and considerations about the future of the project.
Preparation :
1) Install the project dependencies and development environment described at the developer's guide (until the command yarn run configure).
2) Run a test from any package to confirm that everything is correctly setup. Follow the instructions from the developer's guide from the yarn run configure step up to the build-script-decision tree step (excluding).
This workshop only supports Ubuntu 20.04 LTS VM (or bare metal).
