+# LP-0026: Simple Forum App - [DRAFT]
+
+**`Status`**:
+- Draft: Not yet ready
+- Open: Ready for application
+- Completed: Submission accepted, prize completed
+
+**`Logos Circle: N/A`**
+
+## Overview
+
+Public forum to allow open and educational discussion of, perhaps controversial, ideas whilst retaining fundamental rights to privacy.
+With increasing surveillance, personal identification, and targeted retaliation on social media, the internet is losing its ability for people to freely speak their mind and learn rapidly from each other. A forum with privacy at its core provides a safe space for people to exchange ideas without preempting censorship/oppression, eg politics. An important muscle to work to retain free-thinking and not accept capture by authoritarian regimes that seek to isolate individuals and limit free speech.
+
+## Motivation
+
+Enable people to freely discuss ideas on any topic. Filling the gap of tools that allow free and open communication without surveillance and censorship.
+This prize mechanism works well to encourage developers to build for interesting domains, and possibly make unique tech choices. For example this [example forum](https://github.com/jzaki/forum-sample-app).
+
+## Success Criteria
+
+- A number of realistic topics and organic conversations taking place (Checks will be made to assess authenticity)
+
+**Functionality** — what the system must do. Note: applications must not depend on any centralised server or service. Use the Logos stack for communication: **Logos Storage** (storage/data availability), **Logos Delivery** (messaging) for publishing data, **Logos Chat** (messaging) for peer-to-peer coordination.
+- In summary: expected base functionality of a forum application...
+- Ability to have one or more accounts to post from
+- Ability to create new topics and reply to existing ones (text only). Optional extra: emoji reacts
+- Option to reply anonymously, or via unique id, or alias (alongside optional uid)
+- if unique id is chosen to be visible, indicate if it corresponds with msg signature
+- Single forum app, all topics at same single level. Optional extra: ability to create groups of topics
+- Optional extra: your own niche-specific flair/feature(s) if any
+
+**Usability**
+- Provide a Logos Basecamp app GUI with local build instructions and loadable in Basecamp
+
+**Reliability**
+- If offline when would have been received, an app can obtain past msgs
+- If sending a msg fails (eg offline), the text remains available locally to retry another time
+
+**Performance**
+- Does not flood the network
+
+**Supportability**
+- Software design/architecture is sound for the application
+- CI must be green on the default branch
+- A README documents end-to-end usage: deployment steps, program addresses, and step-by-step instructions for interacting with the program via Basecamp app
+- A recorded video demo of the end-to-end flow is included in the submission
+
+
+## Scope
+
+### In Scope
+
+Forum described above.
+
+### Out of Scope
+
+The developer can choose what to include or not, beyond basic forum functionality. This will help builders to differentiate themselves and their apps to stand out.
+- Use of the blockchain module is considered out of scope for this LP so that focus may remain on core forum functionality first. This may be considered in a future LP.
+
+## Prize Structure
+
+- **Total Prize:** $X
+- **Effort:** M
+Top one (or two?) forums with meaningful activity, may be complimentary topics.
+
+## Eligibility
+
+Open to any individual or team. Submissions must be original work. Teams must hold the rights to all submitted code and agree to dual-license it under the MIT License and Apache License 2.0.
+
+## Submission Requirements
+
+> A narrated video walkthrough demo is always required (see [demo requirements](../README.md#evaluation-policies)). The demo should specifically showcase and discuss:
+> - End-to-end usage of the solution, from deployment (or setup) through interacting with the program/app/module in all major user scenarios.
+> - Successful execution of all core functionality, with relevant terminal and/or UI output visible (e.g., proof generation, state changes, error handling).
+> - Any required integration with the Logos stack (e.g., use of Logos Delivery, Logos Chat, or other modules).
+> - Any features addressing explicit evaluation or success criteria (e.g., handling of error cases, reliability under failure, compliance with FURPS requirements).
+> - Unique or innovative design choices, with a brief discussion or illustration during the demo.
+> - (If applicable) Performance metrics, support/deployment workflow, or anything relevant the evaluators should notice.
+> The demo must make it easy for evaluators to verify that the implementation meets the stated criteria.
+>
+> Submissions must include a FURPS self-assessment as part of the solution (see [solution template](../solutions/LP-0000.md)).
+
+## Evaluation Process
+
+By default, submissions are evaluated first-come-first-served against the success criteria. The first submission that meets all criteria wins. Describe any deviations from this default here.
+
+Evaluators will independently clone the repository and run the application from a clean environment; the application must run without modification. Evaluators may also ask technical follow-up questions to verify authorship and understanding of the implementation.
+
+The following policies apply to all prizes (see [evaluation policies](../README.md#evaluation-policies)):
+
+- **Submissions:** each builder (or team) is allowed a maximum of **3 submissions** per prize, with at most **one submission/review per week**.
+- **Feedback:** initial evaluation feedback is limited to a pass/fail indication against the success criteria.
+
+## Resources
+
+- [example forum](https://github.com/jzaki/forum-sample-app)
+
+## Potential for Subsequent λ Prizes
+
+A follow-up prize may be opened to cover adaptation to future release set versions.

+**Note:** The Specification in this Prize describes an outcome that Logos intends to benefit the Logos ecosystem. It sets out criteria and certain requirements a Participant should fulfill in order to potentially be eligible to be awarded a Prize amount, and is not intended to be an instruction or to direct a Participant’s initiative or approach. They are guided by existing approaches and implementations in other mature blockchain systems and their ecosystems, as well as by functional requirements particular to the Logos technology stack or perceived usefulness to such stack or the wider community building on it.

+Logos makes no representation as to the legal or regulatory treatment of this Specification or any implementation of it in any jurisdiction.
+
+Participants act independently, voluntarily and at their own initiative in connection with their Submissions and are solely responsible for:
+
+1. assessing the risks and implications of their Participation in the Program and of any Artefacts that form part of their Submission;
+2. determining whether to obtain independent professional advice;
+3. complying with all applicable laws to them and in connection with the Program, including, where relevant, any licensing, registration, sanctions or anti-money laundering obligations that may arise from operating any software-as-a-service or business.
