# What work has been completed since the start of Intersect

This page showcases the dedication and collaboration of our partners in driving the growth and success of Cardano.

## Contractual progress

Below is a list of completed projects and milestones achieved by our Cardano Continuity suppliers.

<table><thead><tr><th width="165">Contract</th><th width="118">Duration</th><th width="114">Progress</th><th>Summary</th></tr></thead><tbody><tr><td>WellTyped - LSM 1, 2, 3 &#x26; 4</td><td>24th Aug 23 - 13th Dec 24</td><td>10/11 Milestones Complete</td><td>This work develops new Log Structured Merge Tree implementations that will enable long-term scalability and sustainability for the Cardano node, by allowing large data structures to be stored externally to the node (eg on disk/SSD), but in a way that allows the data to be accessed efficiently when it is required.</td></tr><tr><td>EMURGO - Serialization Library, Yoroi Extension Wallet, Yoroi Mobile Wallet, Educational Materials</td><td>1st Jan 24 - 31st Jan 25</td><td>8/16 Milestones Complete</td><td>EMURGO produces Educational Materials which will cover every aspect of CIP 1694, testing and support of the Cardano Serialisation library, Yoroi Extension &#x26; Mobile Wallet.</td></tr><tr><td>Byron</td><td>9th August 24 - 31st December 24</td><td>Contract Complete</td><td>Refactoring of front and back end of Delegation and Voting GovTool pillars 2 and ongoing maintainer role supporting and maintaining GovTool delegation and voting pillars.</td></tr><tr><td>DQuadrant</td><td>9th August 24 - 31st December 24.</td><td>Contract Complete</td><td>Maintainer role for Cardano Govtool Integrated testing.</td></tr><tr><td>IOI - CIP-1649 , Backlog &#x26; Cardano Node Maintenance</td><td>1st Jan 24 - 31st Jan 25</td><td>Contract Complete</td><td>Enables continuation of development of CIP 1694 hard fork in addition to other development work to maintain the network.</td></tr><tr><td>Bitergia - Interactive Ecosystem Visualizations</td><td>Feb 24- Dec 24</td><td>Contract Completed</td><td>Analyzing the footprint and ecosystem network of a client's open source community on GitHub to identify collaboration opportunities, visualize resource interdependence, and integrate external projects into an open dataset</td></tr><tr><td>Tweag - Genesis</td><td>1st Jan 24 - 31st May 24</td><td>Contract Completed</td><td>Ouroboros Genesis mechanism: will enable new nodes to join the Cardano blockchain and bootstrap themselves without needing to rely on a trusted service. It also allows nodes to become disconnected and re-join the network in the same way.</td></tr><tr><td>Tweag - BlockFetch</td><td>20th May 24 - July 24</td><td>Contract Completed</td><td>Developing a modification to the block fetch decision logic to ensure analogous responsiveness from block fetch peers.<br>A report on how to identify a certain type of attack and what actions could be taken to mitigate such it.</td></tr><tr><td>Tweag - Identity Management</td><td>20th May 24 - Aug 24</td><td>Contract Completed</td><td>Tweag will provide IOG with audits for the Identity management script which is an overlay. This script thus relies on the latest PlutusV3 features around governance.</td></tr><tr><td>Galois - Halo 2</td><td>31st July 23 - 17th June 24</td><td>Contract Completed</td><td>Halo 2 eliminates the need for a trusted setup. Development of Zero-knowledge proofs (ZKPs) for future interoperability of the Cardano economy. This contract supports work on repeatedly refining proof obligations until a base obligation can be discharged.</td></tr><tr><td>Tweag - OpenSource</td><td>17th Jan - 15th May 24</td><td>Contract Completed</td><td>Conducted an assessment and provided advisory services to Intersect to develop the vision and strategy of the Open Source Program Office(“OSPO”), ensuring a successful transition for Cardano into an open-source environment</td></tr><tr><td>Tweag - Guardrails</td><td>20th May 24 - July 24</td><td>Contract Completed</td><td>Tweag will provide IOG with audits for the Guardrail script which handles a filtering of users' proposals before being subjected to votes</td></tr><tr><td>DQuadrant Hard Fork Testing</td><td>10th May 24 - 17th July 24</td><td>Contract Completed</td><td>Supporting Chang hard fork development activities by performing regression testing and testing of new features</td></tr><tr><td>VacLabs - Ledger &#x26; Trezor hardware wallets</td><td>10th May 24 - 13th Mar 24<br>[Delayed]</td><td>Contract Completed</td><td>Ensuring the continued practical use of the Ledger and Trezor hardware wallets for the Cardano community and enhancements to support the Conway era</td></tr></tbody></table>

# 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://docs.intersectmbo.org/intersect-knowledge-base/archive/cardano-budget-archive/intersect-operational-services/cardano-continuity/cardano-continuity-suppliers/cardano-continuity-reports/what-work-has-been-completed-since-the-start-of-intersect.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.
