Ecosystem Test Environment: Progress Report 3 (Final)

2nd Interim funding for Fellowship Secretary

### Summary of On-Demand Integration Proposal for Polkadot

- **Objective**: Develop customizable and well-documented on-demand integration modules for Polkadot.
- **Coordination**: Slot width (`w`) configurable via on-chain governance; initial version limited to one block per `w`.
- **Decentralization**: On-demand orders incur costs; governance can switch to bulk Coretime, stopping new orders.
- **Block Production**: Conditions for block production defined by each parachain; verifiable by runtime.
- **Credit Automation**: Transition to credit-based on-demand orders; module to periodically purchase credits for active collators.
- **Proposal Scope**: Includes order placement logic, configuration pallet, credit automation, example parachain, and documentation.
- **Timeline**: Estimated 1.5 to 2 months for completion.
- **Budget**: 18,000 USDT requested for initial development; audit costs to be covered separately.

Merkle Mountain Belts (MMBs) are a new data structure that can be used to commit to a database and provide a compact proof of the existence of an item in it to a verifier. MMBs can reduce operational and access costs for databases with a specific distribution of queries. MMBs would save over 40% of leaf membership proof cost per transaction against MMRs in BEEFY's use case. The proposal includes a published research paper on MMBs, a Rust library implementing MMBs, and the integration of MMBs into BEEFY. The OpenGov treasury will fund the research and success reward milestones, and the Technical Fellowship Committee (TFC) will fund the implementation milestones.

Merkle Mountain Belts (MMBs) Funding Proposal

SubSquare is a team of experienced Rust developers who want to contribute to the Polkadot ecosystem through Kreivo and VirtoSDK. Kreivo is an innovative project that aims to create a more accessible and efficient environment for both developers and users. VirtoSDK is a Rust-based toolkit for Polkadot development with focus on simplicity and portability. The team aims to support developers with tools for sustainable development practices, improve user experience for broader accessibility, and explore governance models that may inform future Polkadot developments. Longer-term funding would be ideal for retaining talent and maintaining project continuity.

Virto Team Funding Proposal

- Polkadot Anti-scam Team protects the Polkadot community from scams.
- They want to join the Polkadot Alliance and be promoted to a Fellow.
- The team's goal is to create a secure and trusted environment for the Polkadot community.
- They have a proposal that outlines their value proposition for the Alliance.
- The team is looking for feedback on their proposal.
