## 2. Solutions

***

ConnectionChain: "allows the "Extended Smart Contract" feature to function autonomously, enabling multiple external blockchains to operate as one integrated system. To connect different kinds of blockchains, it is necessary to develop a connection that absorbs the differences in the specifications of each blockchain, but since each type of blockchain needs to be developed, “ConnectionChain” has streamlined this development by incorporating plugins called Cacti-LP（Ledger Plugins）, developed by “Hyperledger Cacti,” an OSS project hosted by the Hyperledger Foundation on the theme of ensuring interoperability. This enables “Data e-TRUST” to connect to the various blockchains supported by “Hyperledger Cacti,” making it easier to build new Web3 services."

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://qualitax.gitbook.io/interop/solutions-providers/fujitsu.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
