Federated Social Pinning Service

The **Federated Social Pinning Service** is a cooperative, semi-automated network designed to keep important files alive on IPFS by combining free-tier pinning services, homelab nodes, institutional nodes, and trusted social agreements.

It is a core module of the broader Anarchive initiative, responsible for **redundancy, resilience, and archival integrity** of culturally or scientifically significant digital assets.

# Architecture Overview Federated Pinning consists of multiple cooperating layers: - Social Layer — human trust, reciprocal pinning favors, federated identity - Pinning Services — coordination with public IPFS pinning APIs - Homelab Nodes — decentralized, self-hosted IPFS nodes (Raspberry Pi, NAS, etc.) - Verification Mesh — automated proof-of-presence, re-pinning, and reporting - Metadata and Naming — YAML/Back Matter + Federated Wiki JSON for canonical naming and social indexing - Cluster Optionals — optional IPFS Cluster deployments for syncing trusted peer nodes Each of these layers can be implemented gradually. Together they form a **socially-coordinated, semi-automated IPFS-based redundancy network**.

# Core Functions - Pin Distribution: Coordinate uploads to multiple public and private pinning services - Social Reciprocity: Use federated wiki identity and mutual agreements to ensure community pinning - Integrity Checks: Use scheduled checks to verify pin presence and alert if files are at risk - Content Naming: Use IPFS multihash filenames and Back Matter YAML to assign stable identifiers - Perspective Forking: Allow people to fork canonical files with additional context, notes, or localization

# Stakeholders - Archivists: Curate and upload files to the Anarchive - Pinning Allies: Individuals or institutions who agree to pin selected files - Verifiers: Agents or tools that periodically check file availability - Consumers: End users who access media via wiki pages or public gateways - Libraries: Institutions that provide long-term node hosting and pinning capacity - Anarchive Maintainers: Oversee the coordination layer and trust graph

# Next Steps - Define YAML `Back Matter` format for pin metadata → Metadata and Naming - Describe public API coordination logic → Pinning Services - Outline social trust rules and reciprocity ledger → Social Layer - Write homelab setup guide and node script → Homelab Nodes - Build watchdog check loop and alerting → Verification Mesh This modular design allows different contributors and communities to participate at their own comfort level while building toward a resilient, federated preservation web.
