    • Key Tradeoffs: Balancing rapid development with interoperability; prioritizing MVP features over complex solutions.

  2. Protocol and Identity Standardization:

    • Active debate over adopting existing protocols (e.g., Matrix, ActivityPub) vs. custom solutions like Polyproto.
    • Major Decision Points:
      • Tentative adoption of Polyproto’s p2-core for identity federation (led by @alexia and @dark).
      • p2-chat protocol remains unimplemented, with potential custom development.
    • Identity Format: Hybrid format (e.g., [email protected]) proposed but not finalized.

  3. Infrastructure Architecture:

    • Instance Isolation vs. Global Features: Architecture prioritizes isolated instances to simplify moderation and legal responsibility.
    • Data Migration Challenges: Concerns over scalability and cost of migrating large datasets (e.g., 1M+ messages).
    • Premium Feature Portability: No consensus, but proposals to restrict cross-instance access for bandwidth-heavy features (e.g., video).

  4. Collaboration and Open Source:

    • Polyproto Partnership: Interest in collaboration for protocol alignment but skepticism about its maturity (led by @alexia and @jce).
    • AGPLv3 Compliance: Ensures transparency as community contributions grow; private branches may phase out post-refactor.
    • Self-Hosting Prioritization: Documentation for self-hosting prioritized over federation due to scaling demands (driven by @Monty and @florian).

  5. Implementation Roadmap:

    • MVP Focus: Core federation features (multi-instance client connections, identity via p2-core) prioritized over complex issues (data migration, premium portability).
    • Technical Hurdles:
      • CORS and VoIP: Solutions needed for cross-instance communication and LiveKit integration.
      • DM Storage: Debate between centralized (Fluxer-hosted) and federated models with encryption (led by @florian and @ima).

Major Architectural Decisions

Key Tradeoffs and Unresolved Issues

  1. Polyproto vs. Custom Solutions:

    • Pros of Polyproto: Accelerated development via existing specs (p2-core), potential interoperability.
    • Cons: Perceived immaturity, risk of impedance mismatch with Fluxer’s rapid iteration.

Weekly Summary: Fluxer Chat Application Federation Infrastructure

Overarching Themes

  1. Federation Architecture & Privacy

    • Decentralized Design: Agreed to avoid centralized gateways, prioritizing a peer-to-peer server-to-server model. [@gustave] explicitly rejected centralized systems.
    • Privacy Mechanisms: Roadmap confirmed use of OAuth and non-storage of user data on external servers. [@Didi] cited this as a core technical requirement.
    • Relay System: Proposed as a temporary solution until full federation is implemented, though long-term feasibility remains uncertain.

  2. Monetization & Access Control

    • Subscription Model: Consensus leaning toward restricting Plutonium-tier features (e.g., higher bandwidth, premium emojis) to the main instance (web.fluxer.app), with multi-instance subscriptions deemed impractical due to user friction. [@maelstrom, @glyph, @gustave] emphasized this as a more realistic approach.
    • Cross-Instance Feature Access: Debate over whether features like stickers or streaming should be available across instances. [@jce] proposed a pay-per-instance model, but no resolution reached. Tradeoff between accessibility and monetization complexity.

  3. Protocol & Technical Implementation

    • Rejected Solutions: Matrix protocol dismissed due to scalability issues, poor moderation tools, and client fragmentation. [@Atakku] detailed these drawbacks.
    • ATproto Consideration: Emerging interest in ATproto for identity management and federation, though current implementations (e.g., roomy.space) are deemed immature. [@ember, @dubliv] highlighted its flexibility.
    • XMPP Debate: Some users (@danct12) advocated for XMPP over newer protocols, while others pushed for alternatives like polyproto. No final decision.

  4. Resource Management & Scalability

    • Emoji/Reaction Handling: Agreed to implement instance-level caching and persistent storage for custom emojis to reduce server strain. [@myachan, @Speykious] led discussions on abuse mitigation (e.g., error-checking for broken assets).
    • Private Chats Uncertainty: ATproto’s suitability for private chats questioned; focus shifted to identity federation first. [@tulilirockz] raised concerns about compatibility.

  5. Unresolved Challenges

    • User ID Management: Disagreement between compound IDs (proposed by [@Vero]) and entropy-based IDs (suggested by [@myachan]). No consensus on schema design.
    • Guild Migration: Idea to support community transfers between instances raised but not explored further. [@zulc22] proposed it as a desirable feature.
    • Roadmap Alignment: Uncertainty about the 2026 roadmap’s mention of "federation in development," with [@Monty] questioning whether it reflects new efforts.

Major Decisions

Key Tradeoffs

Issue Options Considered Stated Preferences
Protocol Choice Matrix, XMPP, ATproto, Polyproto-core Reject Matrix; split interest between XMPP (legacy support) and ATproto (flexibility).
ID Management Compound IDs (user:server:home) vs. high-entropy IDs No decision; ongoing evaluation of tradeoffs between uniqueness and simplicity.
Cross-Instance Features Free access vs. pay-per-instance model Leaning toward restricting premium features to primary instance.
Relay vs. Polyproto-core Relays for IP obscuring vs. Polyproto-core implementation Relays chosen as "permanent plan," though tradeoffs (complexity vs. simplicity) unaddressed.

Notable Contributions by Users

Open Questions & Next Steps

  1. Finalize protocol selection (XMPP vs. ATproto vs. custom solution).
  2. Resolve user ID schema design.
  3. Address private chat support in federation.
  4. Evaluate long-term relay system efficacy.
  5. Clarify roadmap alignment with federation development timeline.

Conclusion: Progress focused on defining core architectural principles (decentralization, privacy) and mitigating technical risks (resource strain, protocol choice). Monetization and cross-instance feature access remain contentious, requiring further user and technical evaluation. Immediate priorities include ID management, emoji caching implementation, and protocol benchmarking.

Fluxer Federation & Infrastructure Weekly Summary

Overarching Themes

  1. Federation Status & Roadmap Prioritization:

    • Federation is not yet implemented and remains in early design phases.
    • Prioritization of platform stability and self-hosting readiness delays full federation deployment.
    • Interim relay system proposed as a stepping stone for cross-instance identity federation.

  2. Protocol & Architecture Debates:

    • Protocol selection unresolved: ActivityPub (Fediverse), Bluesky’s ATProto, or a custom solution.
    • Matrix protocol criticized for storage inefficiency and legal risks (content replication); Fluxer aims for lightweight, event-driven synchronization to avoid these pitfalls.

  3. Infrastructure & Self-Hosting Challenges:

    • Hardware: RAM-intensive Cassandra databases favored for multi-region HA, while SQLite suits smaller instances.
    • Storage: Cost-effective solutions like Backblaze B2 proposed for media, with retention policies to mitigate bloat.
    • Refactoring: Backend rewritten in Rust for performance; current codebase complexity hinders progress.

  4. Security & Data Sovereignty:

    • Encryption and signing keys agreed as baseline protections.
    • Avoidance of Matrix-style content replication to preserve data control.
    • Trust models under discussion to manage inter-instance moderation and illegal content.

  5. User Experience & Feature Design:

    • Plutonium (premium features) likely tied to home instances to ensure infrastructure cost coverage.
    • Cross-instance interactions (e.g., emojis, reactions) require standardized formats (e.g., instance.id:emoji:ID).

Major Architectural Decisions

Key Tradeoffs

  1. Federation vs. Centralization:

    • Balancing decentralized identity with centralized content hosting (communities reside on origin servers).
    • Risk of semi-centralization (à la Bluesky) avoided by rejecting protocol dependency on a single entity.

  2. Self-Hosting Flexibility vs. Cost:

    • Full control over features (e.g., upload limits) for self-hosters, but Plutonium benefits require per-instance subscriptions to cover infrastructure costs.

  3. Storage Efficiency vs. Complexity:

    • Avoiding Matrix’s storage-heavy replication in favor of event-based state management, though this introduces complexity in conflict resolution.

  4. Speed vs. Security:

    • Caching proposed to speed up room joins but deemed secondary to resolving state synchronization challenges.

Critical Unresolved Issues

  1. Inter-Instance DMs: Key exchange mechanisms for cross-server DMs remain unresolved.
  2. Community Portability: No clear plan for migrating communities between instances.
  3. E2EE in Public Spaces: Technical and moderation challenges need further exploration.
  4. Migration Tools: No implementation for user/data migration between instances.
  5. Trust Networks: Centralized vs. decentralized moderation trust systems under debate.

Key Participants and Drivers

Conclusion

The week focused on solidifying foundational decisions for federation, privacy, and scalability. While the User-to-Server model and Rust refactor are now clear priorities, unresolved technical challenges (e.g., inter-instance DMs) and infrastructure tradeoffs (e.g., E2EE scope) require further exploration. The team remains cautious about overextending, with stability fixes (e.g., voice chat) deemed critical before advancing federation features. Self-hosting and user-controlled data sovereignty remain central to Fluxer’s value proposition.
